Evaporative Air Conditioning – Evaporative cooling |
Traditional DX (Refrigerant) Air Conditioning |
|
Low operational cost. Uses only 10% of energy in comparison with traditional air conditioning |
High operational costs. Very high electricity consumption |
|
Low system installation costs. Does not require long and expensive ventilation ductwork. Frequent possibility of simple installation via the roof or wall |
High installation cost. Long ductwork ventilation system quite often required |
|
100% clean and fresh air. The ambient air gets cleaned whilst passing through constantly sprayed and wetted cellulose pads |
Offers very restricted volume of fresh and clean air due to high recirculation rate. It presents potential health hazard and is burdensome especially to people with allergies, children and elderly persons |
|
During operation of Evaporative Air Conditioning the area windows and doors should remain open or the mechanical extract ventilation system should be turned on. It does not have a negative impact on the cooling effect |
During operation of the DX refrigerant system the area doors and windows should be kept closed. The effect of that is stuffy, bad and unhealthy air. Opening of the windows and doors will worsen the cooling effect or it will be hardly perceptible |
|
Does not cause air dry-out |
It dries out the air. It is harmful for skin, eyes and plants. |
|
The cooling medium is water |
The cooling medium is refrigerant gas potentially harmful to the Earth ozone layer and natural environment |
|
Emission of carbon dioxide (CO2)to the atmosphere is low (just 10% of the traditional DX air conditioning) |
High CO2 emissions |
|
It is environmentally friendly so it is described as GREEN COOLING TECHNOLOGY |
It is not harmful to the environment |
|
Very easy to operate |
Servicing has to be performed by specially trained and approved personnel |
