Evaporative Coolers Fundamentals, Pros and Cons
If you are looking for some way of cooling a area most new users consider air conditioning and evaporative air coolers to be one of the same. There is a fundamental difference in the way an air cooler works when compared to refrigerant based air conditioning unit. Evaporative air coolers use water as its medium of cooling, the water is pumped over a thin sheet of specially treated paper, perforated with air gaps to allows air to pass through which allow evaporation of the water to take place when a forced air fan drives air across it..
The evaporating water cools the passing air and a cooling effect occurs. Air coolers have a limited cooling effect output as the cooling effect it produces isn't powerful enough due to its basic design capabilities when compared with air conditioning. Because a evaporative air cooler doesn't come with a Kw/Btu output rating this makes them impossible to match against a heat load such as a server room or computer ladened room.
Because of the water associated with the cooling effect of evaporation and the need to constantly fill with water, evaporative air coolers are not suitable to be used in areas where a high density of electronic equipment is being used. Evaporative air coolers add moister to the air which can cause in a sealed area particularly a build up of humidity in the room, in server rooms static can build up in low and high humilities and if the server cases are not earthed cause equipment damage. Most evaporative coolers stipulate that the room being treated requires some form of ventilation to prevent high humidity conditions.
Air Conditioning Can Directly Match The Heat Load
As conditioning uses refrigerant as its cooling medium the cooling effect it produces is vastly more powerful. A heat load in a area that needs cooling can be directly matched by the output of the air conditioning unit, this makes refrigeration driven air conditioning a more professional way of cooling. An air conditioning unit has the opposite effect to a evaporative air cooler as it will remove moister from the air, humidity in the air being treated is removed by the cold evaporator coil and usually is collected in a bucket or pumped away.
Summery Evaporative Air Coolers or Air Conditioning?
Air conditioning systems match your heat load so are ideal for professional / commercial areas that require a "set temperature" such as server rooms.
Evaporative air coolers are ideal for residential or light commercial use such as a office.
