Solar Panels For Swimming Pools

Solar Panels for Swimming Pools! Heat Your Pool with Solar Power!

Solar energy has become a popular choice for homeowners who wish to generate their own clean electricity or heat and save on their bills. Even though electricity generating solar panels are the most talked about technology, solar thermal has been around for a longer time and was the first solar energy production to be widely commercialised in the UK. Solar thermal collectors harness solar energy which can then be used for space or water heating. In fact, one of the most popular applications of solar energy is swimming pool solar heating. These systems can heat your pool all year long with clean, free energy. Here are all their benefits.

Why Use Solar Panels to Heat Swimming Pools?

First of all, pools need to be heated even in warm weather, because they lose heat via surface evaporation. There are different ways to heat pools, such as an electric or gas heaters, heat pumps, and thermodynamic panels. So why would you choose solar panels? Solar thermal systems have a short payback period and will help you save money on your bills. While electricity and gas prices are constantly increasing and make your expenses fluctuate depending on the season, solar panels produce completely free and clean energy all year long, for as long as 20 years. Solar heating systems often have automatic control systems, so you won’t need to monitor them or spend any money on maintenance.

Pros of Solar Panels for Swimming Pools

*Depending on your geographical location and sun exposure, by installing solar swimming pool heaters you could keep enjoying your pool for up to 12 months.

*They have no additional costs of pool solar heating after installation and eliminate fuel costs.

*They last up to 20 years with no need for maintenance, and they usually carry a 10-year warranty.

*They are easy to install and can be placed on your roof or on the ground.

*They are the best choice for the environment and work in different climates, not just warmer ones.

*Solar swimming pool heaters are suitable for both residential and commercial purposes.

*Even the most extreme weather conditions will not damage the collectors: they are built to withstand hurricane-level winds exceeding 241 Km/h.

*The solar collectors work even in overcast weather because the sun’s thermal energy is unaffected by clouds. Active rain may cool them down, but they quickly regain their ideal temperature. Moreover, rain helps clean the collectors and makes maintenance easier than in dry climates.

How Do Solar Panels for Swimming Pools Work?

Swimming pool solar heating systems are efficient and easy to use. There are only four components in the complete kit: a solar collector, a pump, a valve and a filter. Debris is removed from the water through the filter, then the pump leads the water to the solar collectors, which heat it by using the sun’s energy. Then, the warmed water is pumped back to the pool. A flow control valve (manual or automatic) diverts water through the collectors.

Types of Solar Panels for Swimming Pools

*Unglazed solar collectors: this is the cheapest, simplest option. Unglazed collectors are not covered by a glass layer and are made of plastic or rubber. They have the disadvantage of being less efficient in cold climates but are much more cost efficient than their competitors. They are the best choice if you are only going to use your pool in above-freezing temperatures.

*Glazed solar collectors: these panels are more expensive, mainly due to the materials they are made of (copper, aluminium and iron-tempered glass). They are more efficient in cold climates and can be used all year long, even to for domestic water heating. However, both glazed and unglazed collectors can benefit from a freeze protection if they are intended to be used in extra cold conditions.

Useful Tips

In order to maximise the efficiency of a solar pool heating system and to be as environmentally friendly as possible, there are a few things you should consider.

*Using a pool cover helps lower the evaporation and preserve the heat you generate. Pool covers are not required but are a fundamental addition to solar heating kits. Dark coatings are recommended as they capture even more heat from the sun.

*In order to maximise the panels’ efficiency, you should make sure they are properly exposed to the sun (South-facing installations are recommended) and free of any shading.

*The size of the installation should be between 30% and 60% of the pool area or more.

Winter Pool Maintenance

Winter Pool Maintenance: 7 Off Season Pool Care Pro Tips

Depending on the region you live in, ongoing pool care can be a year round requirement. Yes, the water temperatures are cold, UV ray angles are low and your pool might not have any bather load; however your pump, filter, heater and other pool equipment are functional and need to be watched.

When it’s finally the warm pool opening season, you don’t want to find out that your pool surfaces and equipment are damaged and unusable. By doing small, weekly pool care tasks, like balancing your water chemistry, you can save yourself from large, time-consuming repairs and replacements. To avoid unexpected problems when it’s time to open your pool for the summer, follow these seven off season pool care tips this winter:

1. Keep an eye on your pool

If your pool is covered, remember to periodically remove any debris above the cover and check underneath it to ensure you have no unwanted surprises down there.

In addition, the winter-induced wind or snow can put stress on your cover, so make sure that your cover, attachments, water bags and lawn anchors are securely attached so they don’t come loose.

Winter Pool Maintenance

2. Balance your water chemistry

Water chemistry balancing is not as demanding as it may seem, but it is a crucial part of protecting your pool or spa investment. If pH, alkalinity, cyanuric acid and calcium hardness are out of standard ranges for an extended period of time, it can wreak havoc on your pool equipment and surfacing.

In the winter, you should balance your pH, pool water weekly at a minimum; spa users are recommended to check their water chemistry every two to three days. In addition, use an algaecide to kill any existing algae and prevent new blooms during the winter. Your sanitizer levels can be reduced during the winter months, while still maintaining the proper water chemistry balance.

3. Check on your equipment

Even when your pool is covered and not in use, dirt, pollen and other contaminants can still enter the water. So, remember to keep an eye on the filter gauge, perform backwashing and clean your filter per the manufacturer’s recommendations. Additionally, don’t forget to check your pool pump, heater and exposed plumbing to make sure everything is functioning properly and there are no leaks.

4. Beware of freezing weather

If water is left in your equipment during the winter, the cold weather can freeze and expand the water and ruin your equipment and plumbing. So remember keep an eye on your freeze guard to ensure that your pool equipment has circulation when temperatures plummet. This can help you avoid expensive repairs from frozen equipment or plumbing.

5. Clean your pool surfaces

Maintaining clean walls, floors and other pool surfaces will prevent algae growth. Skimming, vacuuming and brushing organic debris on a weekly basis is a great off season pool care habit that will save you time dealing with a green, dirty water in the spring.

Tip: Don’t forget to brush the hard to get areas, including behind ladders, steps and corners.

6. Clear out unwanted debris

As debris builds up, remember to empty your skimmer baskets, pump baskets, floor cleaner containers and cleaner bags. This will keep your water and equipment cleaner, while also making your life easier in the spring.

7. Monitor your water level

Always make sure your pool’s water level is correctly topped off to protect your pump and keep the pool primed. The right pool water level can depend on the climate you live in. If you live in a warmer environment, that doesn’t experience freezing temperatures, your pool water should almost be filled to the top during the winter. However, if you are located in a cold environment, your pool water should be four to six inches below the skimmer in the winter months. Spending a little time each week on your off season pool care will make a big positive impact on opening your pool this spring and summer.

Enjoy Life Without Pollen

In spring and summer our gardens bloom with life. While this may seem nice, it can also cause people suffering from seasonal pollen-related asthma and allergies, such as allergic rhinitis. But what is pollen and how can you protect your family from its possible effects?

What is pollen?

Pollen, which usually appears as a fine powder, is microspores that are transferred from one plant to another, resulting in the fertilization and production of new plants. As temperatures rise, pollen production increases causing a variety of symptoms in people with pollen sensitivity including sneezing, nasal congestion, redness, itchy eyes and tearing and / or itchy nose or runny nose.

Pollen season

There are three main types of pollen that together extend the pollen season from early spring to late autumn.

  • Pollen from grass: It is the main culprit for asthma and pollen allergies associated with pollen and can affect people from March to October. Grass pollen can cause extremely strong reactions.
  • Tree Pollen: While different types of tree pollen occur at different times of the year, tree pollen is usually only a problem from February to June.
  • Weed Pollen: Weed pollen most often causes allergic rhinitis. It usually prevails in summer and early autumn.

Protect your family with Daikin air purifiers

Daikin air purifiers are the perfect way to ensure that indoor air is cleaner, healthier and cleaner, minimizing the negative effects of pollen on your health.

Daikin air purifiers:

Minimize the symptoms of asthma and allergies by removing dust and pollen particles from the air.

Heat Pump

Heat Pump For Domestic Hot Water

What is a Heat Pump?

A heat pump system circulates heat from an external energy source to a compressor inside a heat pump unit. It can collect low-grade heat from renewable sources such as water, ground or air to compress and deliver heating and hot water to a property.

Advantages

 The actual set of the heat pump is controlled by a climate curve for preventing that the hot air taken from outside (over 25°C with water at 65°C, over 35°C with water at 55°C) may cause high pressure alarms.

The electrical heater integrates automatically the temperature of the tank to the desired setting when the actual setting is controlled by the weather curve.

Predisposition for integration with photovoltaic system. After enabling the photovoltaic inverter, the set temperature will increase to the maximum value (according to the climate control).

Flexibility and Benefits

Problem with Space? This is the answer. Compact efficient. Solar and 3rd party heating option connections available.

Waste heat recovery: the unit can be installed near the kitchen, in the boiler-room or the garage, basically in every room which has a largenumber of waste-heat so that it has the higher energy efficiency even with very low outside temperatures during the winter.

Hot water, cooling and dehumidification: the unit can be placed in the laundry room, in clothing room, gym or garage. When it produces howater it lowers the temperature and dehumidifies the room as well.

Compatible with solar energy: the unit can work with a second heat source as solar panels, boilers or other different energy sources (remark: the extra heat source is not provided with). The function for which the unit has been designed is only that of heat pump for DHW production. Any other side effect (ambient cooling, dehumidification, waste heat recovery) should be considered as a perk.

The performance data are therefore provided only with respect to the function of water heating.

Technical Features

  • Steel tank with double layer vitrification.
  • Anti-corrosion magnesium stick for assuring the durability of the tank.
  • Condenser wrapped externally to the boiler, free from fouling and gaswater contamination.
  • High thickness polyurethane foam (PU) thermal insulation.
  • Outer shell made of grey colour plastic material.
  • Acoustically isolated top part plastic cover.
  • Highly efficient compressor with the R134a refrigerant.
  • High and low gas pressure protections.
  • Electrical heater available in the unit as a back-up (with integrated thermo cut out with protection set at 90°C), assuring constant hot water even in extreme cold winters.
  • ON-OFF contact for starting the unit from an external switch.
  • Weekly disinfection cycle.
  • Possibility of manage hot sanitary water re-circulation or solar water integration (presence of a dedicated temperature probe, flow switch input and command for an external pump).
  • Electronic expansion valve for precise control
  • The pipeline intake/discharge of the air can be reduced from 177 to 160 mm by a reduction / diaphragm (not provided) inserted into the end of the pipeline.

Solar Thermal

How It Works

Have you ever felt warm water trickle out of a garden hose that’s been sitting in the sun? If so, then you have witnessed solar water heating in action.

Now imagine that same water moving slowly though a system specifically designed to heat and store water – that is the essence of solar thermal water heating. People have for centuries used water heated by the sun and stored it for bathing, hand washing, cleaning clothes, heating homes and much more. The solar thermal systems used today combine the most efficient techniques for capturing the sun’s heat with modern plumbing systems to produce cost-effective hot water and reduce the need for gas or electricity to heat water.

A Solar Thermal system works by harnessing the sun’s energy and converting it into heat, that is then transferred to your home or business. The solar collector utilises the sun’s rays to heat a transfer fluid which is a mixture of water and glycol, to prevent the water from freezing in the winter. There are a number of different solar thermal designs, but all are based on the same simple principle as the garden hose. Each has its pros and cons, and each is suitable for a specific application. 

Types of Systems

An important distinction among solar thermal systems is whether they are of direct or indirect design.

Indirect system

In an indirect system, also known as “closed loop,” a simple pump moves the antifreeze solution through a loop into the solar collector, through the collector’s pipes, and out of the solar collector. Then, the sun-warmed antifreeze solution flows into a heat-transfer unit where it warms the cool water heading into a conventional hot water tank. The antifreeze solution then returns to the pump and again flows into the solar collector without ever mixing with the building’s water. Indirect systems are encouraged in climates with extended periods of below-freezing temperatures. We primarily install these types of systems. We find they produce the greatest amount of energy, more consistently, with a greater service life than other types of systems.

Direct system

A direct system, also known as “open loop,” is a little simpler. There is no antifreeze solution; the water heated directly by the sun is the same water used by building occupants. A thermometer and controller sense when the solar collector is warm and ready to heat water. The controller starts a pump that moves cold water into the solar collector, where it is heated. The solar heated water is then stored in a conventional hot water tank. It is typical, especially during high use or periods of little sun for the water to be kept warm through supplemental gas or electricity. This type of system, because it circulates pure, potable water through an outdoor collector, is susceptible to freezing in many climates, unless safeguards are added.

Applications of Solar Thermal

  • Solar Thermal Under floor heating

  • Solar Thermal Heating of domestic water

  • Solar Thermal Heating of the pool

  • Combination of the above

5 Elements To Consider When Buying An Air Conditioner

When investing in an air conditioning system, the right type, model and performance play an extremely important role. Air conditioners significantly affect your comfort and health at home. These tips will help you choose the right air conditioner for your space and needs, so that you make the most of your investment.

1. Yield Throughout The Year

All Daikin units cool homes with an energy efficiency of up to A +++, the highest on the market, while keeping the electricity bill low. With our solutions you will enjoy a perfect atmosphere throughout the year in an energy friendly way.

Mechanical Engineering Cyprus

2. The Correct Performance

When choosing an air conditioning system it is important to determine the required cooling efficiency. A system with very low power provides unsatisfactory results, while a system with more qualifications than required has a stronger air flow than required, resulting in unpleasant comfort. Finding the perfect performance is a balancing act, but your Daikin installer can help you with that.

3. What Suits Your Interior

Every house is unique. With sleek air conditioning and a wide range of models, Daikin offers comfortable and energy-efficient solutions for every room.


Our wall-mounted units  fit perfectly into any interior, offer great comfort and some have been awarded the most prestigious design awards.


Our floor units  fit perfectly under a windowsill or in a room where light is limited.


If you do not want your indoor unit to be visible, you can choose a hidden roof unit . This model is integrated in suspended ceilings or false walls so that only the output grilles are visible.

4. Take Care Of Your Outdoor Unit

When installing an air conditioner with an outdoor unit, many people only pay attention to the indoor unit because it is more visible indoors. But the location of the outdoor unit is probably more important as it can significantly affect the proper functioning of the whole system. The outdoor unit is located in the heart of the air conditioning system, so you should not forget it. Ensure that air inlet and outlet are not obstructed by obstacles or leaves. Take a look at your unit before the start of the summer and winter seasons to ensure optimal operation.

5. Timely Order Of Your Unit

Do not wait for the first hot day to order your air conditioning system. Firstly because you will not be the first to want a quick installation of a unit and the program of authorized installers will be full. Secondly, it takes time for the air conditioner of your choice to be sent to you. The time period between ordering and actual installation can take several weeks. Indicatively, the installation of an air conditioner usually takes one working day for a room. The exact installation time depends on the exact installation conditions.

10 Pool Maintenance Tips That You Need To Try

The idea of having a pool in your own backyard will always be incredibly glamourous. It’s easy to give into daydreams of hosting weekend parties, adopting an invigorated fitness routine that includes laps after work, and spending long afternoons lounging poolside while cultivating the perfect tan. But, in those daydreams, one crucial element of pool ownership is often forgotten: the maintenance. Without a proper maintenance routine, your pool could succumb to a variety of less-than-luxurious conditions – green water, broken filters, and algae build up, just to name a few. And, no one wants to lay by a pool that’s seen better days. Here are 10 pool maintenance tips that you need to try right now. Whether you have just opened your pool for the very first time or you have been a proud owner for years, check out these tips to get your summer season off to the right start.

1. Make A Skimming and Scrubbing A Part Of Life

Skimming the leaves and debris off of the surface of the water is a no-brainer, but it bears repeating. For a truly pristine pool, skimming  should be done daily.If you have a bit of money to spend, consider buying a robot vacuum that will clean the bottom of the pool for you. In addition to skimming, you need to scrub  the sides of the pool to prevent algae build-up. Thankfully, that doesn’t need to be done quite as often. You can get away with scrubbing once every other week. Just look for any growths and go at them with a scrub brush to keep your siding looking fresh and clean. For those particularly stubborn spots that won’t go away with any amount of elbow grease? Repurpose an old sock. Fill it with chlorine and let it sit on top of the spot for a few hours before scrubbing once more. The chlorine will eat away at the algae and you will finally have a use for those socks without pairs. It’s a win-win.

2. Think Of The Filter As Your Pool’s Kidneys

Just as your kidneys are constantly working to remove impurities from your body, your pool’s filter is responsible for removing impurities from the water – think dirt, leaves, and even small toys. Most of the time, the pool can be cleaned by turning off the filter, removing the filter cap located on the pool deck, lifting out the filter basket, and removing any debris before replacing everything. It’s best to clean out your filter basket at least once a week. Once a month you will also want to clean out the pipes utilized by your filter system, which you can do by backwashing. To do so, simply set your filter to “backwash,” remove the leaf basket and clean it out. Then turn on your pump and let it run until the waste pipe ejects clear water. A final note on turning the filter on and off: doing so too often can cause the filter’s mechanics to crack. Set your filter on a timer and allow it to run for at least six hours a day.

3. Pools Need Consistent Chemical Levels

Chemical levels are arguably one of the most important facets of pool maintenance.  Improperly balanced water looks murky, irritates skin and eyes, and can cause your pool to become a breeding ground for bacteria.Ideally, you should test the water at least once a week. According to the Center for Disease Control (CDC), there are six chemical levels that need to be considered:

  • Cyanuric Acid – Protects chlorine from sunlight and determines the required Free Chlorine level. An ideal reading for outdoor pools is 30- 50.
  • Free Chlorine – A sanitizer which keeps your pool water safe and free of germs.
  • Acidity/Alkalinity – Also known as the PH level, acidity needs to be kept between 7.5 and 7.8 to prevent irritation and protect the pool equipment from eroding.
  •  Total Alkalinity –  Helps keep the PH in balance. Levels should be within range of 60-120.
  • Calcium Hardness – Appropriate levels help prevent plaster damage. Aim for 220-350, but lower for pools with vinyl siding.

Testing the water is easy. Simply buy a few testing kits from your local pool store. Fill it with a sample of your pool’s water. Add the provided solution to the testing kit and close the vials. After a few seconds, your sample water will change color and a comparison of the sample water to the colors shown on the testing kit should allow you to determine the current chemical levels. You should adjust the levels, as needed, to achieve an ideal balance.When all the chemicals are properly balanced, the water should be crystal clear, have no scent, and leave very little residue on your skin.

4. Chemicals Costing Too Much? Give Baking Soda A Try

There’s no denying that pool chemicals can be expensive to purchase, so why not get a little help straight from the grocery store? Most pool stores suggest using sodium bicarbonate to control the alkalinity of a pool without drastically reducing the PH levels. They will try to  sell overpriced solutions in order to get the job done. As it turns out, regular baking soda does the same job as sodium bicarbonate for only a fraction of the price. All baking soda boxes even have “sodium bicarbonate” listed on their ingredients label. Take a look! If you are worried that using baking soda will mean doing a lot of complicated mathematical conversions, don’t be. Baking soda has the same concentration of sodium bicarbonate per pound as the solutions, so the amount you would need to add to your water would be identical.

5. Don’t Be Afraid To Shock A Cloudy Pool

On the topic of chemicals, don’t be afraid to shock your pool when necessary. While that may seem like a process only fit for public pools. But, think about how your pool water looks after you throw a big party. Odds are it’s murkier than it was the day before the big bash. That murkiness? It’s bacteria that you will want to get rid of as soon as possible. Shocking refers to drastically raising the chlorine levels for a short period of time to kill bacteria. It’s done by diluting three to five times the normal amount of chlorine or other chemical sanitizer with water, slowly poring it into the pool’s return line, letting it filter throughout the pool, and then slowly refilling the pool with water over time. While shocking too often would risk damage to your pool’s siding, you should aim to shock the pool at least twice every season.

6. You Need To Keep An Eye On The Water Level

As important as the chemical composition of the water is, the physical water level is just as important. The levels will naturally fluctuate after a heavy rainstorm or an afternoon of kids doing cannonballs.You want to maintain a level that is halfway up the opening of your skimmer. If the water is too low, simply use a garden hose to add the necessary amount of water back in. If the water level is too high, rent a submergible pump from a home improvement store to drain the excess. However, if you are pool’s liner is a vinyl or fiberglass material that could be easily damaged by the weight of the pump, consider consulting a professional.When you’ve reached the appropriate water level, remember to recheck the chemicals. The water level fluctuations will have thrown them off balance.

7. Power Wash To Make The Pool Deck Shine

The area that surrounds your pool is just as important as the physical structure itself. You can help keep your pool deck shining by power washing. Power washing, also known as pressure washing, will help get rid of any rust or weather stains that occur over time. You can rent a power washer at any home improvement store. Start the process by sweeping the deck free of any errant dirt or leaves first, so you don’t end up spreading them all over during the cleaning process. Then, put the power washer together according to the directions. Set the machine on a weak to medium power spray and remove the surface debris in layers, repeating the process until the surface is clean. As you spray, be sure to overlap the  areas you have cleaned in order to help prevent streaks. You will want the nozzle of the power washer several feet off the surface of the pool deck and maintain this height to prevent gouging.

8. Use A Tennis Ball To Absorb Oils

Most of the time when people think about tennis balls in a pool, they think about playing catch. However, those toys can do double duty. When swimmers exit the pool, certain oils can get left behind in the water – suntan lotion, hair product, the natural oils produced by our skin. While it’s unpleasant to think about, luckily there’s an easy solution. Simply throw a tennis ball into the water. The fibers used to make the tennis ball will help absorb the oils and keep them from leaving a slick sheen on top of the water.

9. Schedule A Yearly Service Appointment – Whether You Think You Need It Or Not

Sometimes you need to trust an expert. Especially when it comes to your pool’s mechanical equipment – pumps, filters, heating systems – you may not have the proper knowledge for care. At least once a year, have a pool service professional come out to check your devices.Before your appointment, take a thorough look at your pool as a whole, making sure to use all of your senses. Compile a list of any leaks you see in the piping, holes you notice in the linear, loud sounds coming from the mechanisms, or odd smells coming from the water. Mention them to your serviceperson in oder to give him or her an idea of where to start.In the event that there is noting amiss with your pool, the yearly service appointment may seem like a waste of money and it can be tempting to cancel. But remember: detecting and fixing a small problem now can save you from having to fix a huge crisis later down the road.

10. Learn How To Properly Winterize To Prevent Damage

As important as pool care is during the summer, it’s even more important to make sure that you properly secure it for winter.  After all, no one wants to remove a pool cover at the start of summer only to find out that their pool has a leak or that their water is full of dangerous bacteria. Taking the right steps to properly winterize your pool can save you lots of time and money on repairs for next season.Before closing up shop in the fall, buy a water testing kit to ensure your chemicals are correctly balanced. Then,  blow any excess water out of your plumbing lines, and invest in a cover to keep the pool free of debris.Keeping a pool in good shape does entail a certain amount of work, but it doesn’t need to be a burden. By incorporating these pool maintenance tips into a regular cleaning routine, you can ensure that you will spend more time sunbathing than doing chores. Which is exactly how it should be.

Geothermal Energy

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth’s surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity. A geothermal energy cooling / heating system is based on using the full potential of the constant temperature and thermal conductivity of the earths substructure.

We can see this phenomenon in basement areas where during the summer the area is cool and during the winter warm without the use of air conditioning.

Geothermal energy can be broken down into two categories: open loop systems and closed loop systems.

Open loop geothermal energy for cooling / heating is the pumping of under ground water source through a heat pump (or VRV) and the return of the water after the energy transfer. This method needs a constant water supply.

mechanical installations

Closed loop Geothermal energy systems can be divide into two categories.

Horizontal closed loop Geothermal energy system is installed at least 1.5 meters below the ground with pipe spacing of at least 1.8 – 2.2  Rm per m². Output is 20 – 35W/m². This system has the disadvantage of requiring a large area to be installed.

Vertical closed loop Geothermal energy system where the loop is installed in a vertical bore well (6” – 8” diameter) and 60 – 120 deep. The minimum distance between the wells is 5 meters and the output is 40-70W/meter of depth, and depending on the soil structure. This system is more popular as you need less space and have a higher output.

The heat which is collected from the earth is transferred to the  system (heat pump, chiller, VRV, etc.) and the exchange is made via heat exchangers and transferred to the cooling circuit of the unit as in a normal system. Due to the fact that the temperature is constant in the earth (±18.5°C) the energy required for this  this process is much less than in a normal system where the  air temperature is 40°C in summer and 5-10°C in winter.

Geothermal  energy can be used for under floor heating, fan coils, or for VRV systems, and the savings in comparison to a normal Air to water system can be up to 50-60% depending on the application and use of system.

Indoor Air Quality Solutions

Why Indoor Air Quality (IAQ) is Important

Indoor Air Quality (IAQ) is the air quality in a building or structure, the air that the occupants of the building breathe every day.

When planning new resiednetial buildings, schools, offices or light commercial buildings, many factors need to be considered. Apart from the construction factors, there are also issues of heating, cooling and something that is often neglected: indoor air quality.

Did you know that the indoor air we breathe, at home, in the office or even in a hotel room, can actually be much more poluted than the air outside?

  • The 90% of our lives is spent indoors
  • The indoor air quality can be 2-5 times worse than outdoor air quality because of pollutants, such as pollen, bacteria etc.

Pollutants And Indoor Air Particles

With the right system (air conditioner, ventilation, air purification equipment), contaminants such as pollen, spores, concrete dust, bacteria, viruses or germs can be removed from the air by filtration. The smaller these particles are, the more dangerous they are to our health, so particulate matter is categorized according to its size.

Particles And Storage Areas

The thinner and smaller a particle is, the longer it stays in the air.

• PM 10: all particles up to 10 µm (0.01 mm)

Deposition in the nose and pharynx of the human respiratory system

• PM 2.5: all particles up to 2.5 (m (0.0025 mm)

They are so small that they reach the human lung

• PM 1: all particles up to 1 µm (0.001 mm = 1 micron)

They are so small that they pass through the cell membrane of alveoli into the human circulatory system and cause life-threatening diseases.

Due to their harmful properties (high risk of cardiovascular disease), their permanence and frequency, particles smaller than 2.5 μm (ie PM 2.5 and PM 1 ) require the most attention .

Elements of indoor quality

Aeration

Ventilation systems ensure optimal air conditioning conditions by providing a fresh, healthy and comfortable environment for buildings of all dimentions and different applications. In a completely enclosed space in a bulding, air cannot enter/leave easly, leaving air pollutants remaining and accumulating in the room. This can effect the health of the people in the room. Ventilation is essential for diluting and removing these air pollutants. A well-maintained ventilation system and and adequate air exchange rate have proven to be an effective solution to protect people from contaminants, incluidng visruses.

Daikin ventilation products are perfectly combined in a total heat pump solution, so that it is possible to reduce the number of individual systems and independent suppliers for your HVAC-R system

To achieve optimal ventilation, Daikin maintains the highest standards of energy efficiency and has a wide range of options to achieve the filtration and level of hygiene required for your project.

Filtering

Filter efficiency classification

ISO 16890

With the introduction of the new ISO 16890 standard, the classification of filters is based on the ability to filter specific particles according to particle size.

A filter is classified in the ISO ePM 1 Filter Group if the minimum filter efficiency is at least 50% (the filter removes at least 50% or more particles ≤1 μm in size) as shown in the table.

The average filter performance is also indicated . If the average yield for ISO PM 1 particles is 68%, then the classification becomes PM 1 65% as the average yield is rounded down to the nearest 5% increase.

HEPA filters

HEPA filters provide extremely high particle filtration and must filter at least 99.95% of particulate matter with a diameter of 0.3 μm!

As such a HEPA filter is more efficient than an ePM 1 filter .

Air disinfection additives for filtration

With a good filtration system you can collect very small particulate matter from the air stream but the viruses, bacteria and fungal organisms that accumulate are not inactivated. They can continue to reproduce and possibly cause disease. To prevent this from happening, air disinfection is required.

Flash Streamer

Superior air treatment through the unique Flash Streamer technology

Daikin’s patented Flash streamer technology disables more than 99.9% of the new coronavirus (SARS-CoV-2).

The huge streamer discharge hits allergens and hazardous chemicals, breaking down and breaking down surface proteins, which are then destroyed by oxidation.

During the test, allergens are placed on the electrode of the streamer discharge unit and then photographed with the electron microscope after being irradiated.

UV-C lamp

UV energy inactivates viral, bacterial and fungal organisms so that they can not reproduce and possibly cause disease.

The entire UV spectrum has the ability to inactivate microorganisms, but UV-C energy (wavelengths 200 – 280 nm) provides the greatest microbicidal effect.

UV-C disinfection and sterilization is widely used in hospitals.

However, the UV-C lamp is a danger to the health of the human body.

By treating the fresh recirculation air with a UV-C lamp directly inside the air management units, pure germ-free air can be achieved without exposing the human body to the harmful UV lamp.
