Refrigerant-based air conditioning works by taking the ambient air inside and passing it through a coil fan. This cools it down and releases it back into the space. However, evaporative cooling takes a whole other approach which delivers many more benefits as a cooling solution.
If you’re wondering, ‘how does evaporative cooling work?’, here is a guide from the experts at EcoCooling, the largest manufacturer and distributor of fresh air direct evaporative coolers in the UK.
How Evaporative Cooling Works
To start, warm air is drawn over wetted filter pads using a motor-driven fan. The pads are kept continuously moist using a water pump. Normally, evaporative coolers are installed on the outside of buildings, but it ultimately depends on space, planning an aesthetics. At EcoCooling, we also have a range of internal coolers that fit inside the space too.
Then, the water naturally evaporates into the air, taking with it the heat required to make it evaporate. The cooling effect from evaporative cooling comes from the energy required to change water from a liquid to a gas.
This is then delivered through a series of outlets, ducts or through the cooler directly wherever it is placed in the building. Therefore, the water acts as its own refrigerant and the air is cooled down to a comfortable temperature.
This results in a steady supply of fresh, cool air for temperate climates like the UK. Its dry heat means the air has a low relative humidity, so it can absorb a large quantity of water and our evaporative coolers can deliver the most cooling effect.
Is It Less Effective With Windows & Doors Open?
There is no need to worry about leaving the windows and doors open when using evaporative cooling. Refrigerant-based air conditioning recirculates the same air round and round, cooling it a bit each time it cycles through, so replacing the cooler air with outdoor air with windows and doors opens means it will never work as efficiently. Evaporative cooling constantly brings in fresh air and exhausts the old air, so you don’t have to worry about recirculation.
