Evaporative cooling is the new kid on the block. It is also known as adiabatic cooling and it works on the principle of evaporation of water by dint of which the air temperature of the room/s is brought down to a bearable and comfortable degree. Evaporative coolers use water as the refrigerant and are extremely environmentally friendly.
Working Principle Of An Evaporative Cooler
During the process of evaporative cooling, the water gets evaporated into a stream of air at first, followed by it turning from a liquid to a gas. This change from the aqueous to a gaseous form needs a lot of energy, which is extracted from the air in the room as heat. Resultantly, the air in the room cools down.
There are 3 ways to apply this evaporative process; direct adiabatic cooling, Indirect adiabatic cooling and Indirect/Direct adiabatic cooling. In all of these cases, the principle of operation is the passage of dry and hot outside air through water-filled filter pads. Consequently, the water temperature is lowered with an increase in humidity. For climates like Australia, where the summers are really hot, evaporative coolers and evaporative cooling are the best solutions.
Here are the advantages and health benefits of installing evaporative cooling systems at home:
1, Best Indoor Air Quality:
When your workplace and its immediate environment is well ventilated with a good deal of fresh air, the employees will give you higher productivity and lower absenteeism. With evaporative cooling, you have 100% filtered and fresh outside air to cool the insides of the room or the building. This is in direct contrast to mechanical cooling where the warm and polluted air indoors is often circulated with the addition of refrigerants.
2. Air Humidity Is Optimal:
Evaporative cooling units will make sure that the relative humidity stays between the optimal range of 40% to 70%. This is the much sought after humidity level where virus protection is ensured and your throat, nose and eyes get the comfort they deserve.
3. Climate Control Along With Energy Efficiency:
Most evaporative air conditioners depend on a two-stage evaporating cooling. In doing so, it uses a minuscule amount of energy- only 10% of what you need with mechanical cooling. With this kind of air conditioning, over 95% of the cooling is through the natural process of evaporation of water. While the evaporative cooling service, 1kWH of electricity will give you an output of 40kWH. In the case of a mechanical cooling system, 1kwH of energy produces 3kWh. So it is quite clear that efficiency-wise, adiabatic cooling is superior to mechanical cooling systems.
4. The Comfortable Environment At Work:
If your work environment is too hot, your employees will find it stuffy and cloggy very quickly into the workday and their productivity will come down. Additionally, they will be unable to concentrate for lengths of time as required in their jobs. There are some two-stage evaporative cooling systems that can bring down the temperature down by 20 degrees centigrade compared to the outside. Not only the office space but the entire building you occupy could be fitted out with evaporative coolers to bring down heating and cooling bills.
5. Environment Friendly:
At a time when world leaders are trying hard to align their objectives to fall in place with the Paris Climate Agreement bill of 2050, evaporative coolers offer a ray of hope for those in the legislation concerned with rising carbon footprints. With evaporative cooling, you have the friendliest cooling solution available. It uses water as a refrigerant, thereby omitting harmful refrigerants in the cycle, ensuring no harmful leakages that affect the ozone layer. For some advanced evaporative coolers, the Global Warming Potential is a big zero, some achievement indeed, considering that most other businesses and products in the same category fall woefully short of the Paris Climate Agreement of 2050.
6. Ecological And Healthy:
Besides being very economical, evaporative cooling is also ecological and healthy. This kind of system will ensure constant removal of heated air and will improve the quality of the air by removal of gases, fumes or unpleasant odours. With this kind of cooling, you can easily keep the doors and the windows open, which is a huge relief for a country like Australia, reeling in heat in the summertime.
7. Repairs:
When something awry happens in a mechanical cooling system, it takes a lot of inspection and expert hands to get the system up and running once again. With evaporative coolers, this is not the case. Evaporative cooling repairs hardly take time, and the technician will be in and out of your house within an hour at most, optimistically speaking.
8. Deduction For Energy Investment:
The Netherlands has taken the lead in giving “Ënergy Investment Deductions”. This gives you an 11% benefit of the whole cooling investment. We hope that Australia also brings this into action, so people can be spurred on to create a planet where self-sufficiency should not be at crossroads with harm to the planet.
9. Air Conditioner V/S Evaporative Cooler:
By looking at the Energy Efficiency Ratio for both air conditioners and evaporative coolers, it is evident that they perform much better in varied conditions, and some have efficiencies oftentimes compared to conventional air conditioners.
Conclusion
Evaporative cooling is capable of being a highly sustainable and energy-efficient method of cooling that provides a productive and comfortable climate for you and your employees working in your office. It can be used in production facilities as well as distribution centres. Needing only 10% of the energy required for mechanical cooling, evaporative coolers give you equivalent temperatures at a fraction of the cost. Lastly, because evaporative coolers do not recirculate the air via artificial refrigerants, you will receive 100% filtered, fresh, cleaned and cooled air to use for your home or office. It is the way forward and people will soon ditch mechanical air coolers in favour of this new kid on the block.
