Comparing Evaporative Air
Coolers and Air Conditioning Cooling Units
Evaporative Coolers Fundamentals, Pros and Cons
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..
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.
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.
Conditioning Can Directly Match The Heat Load
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?
conditioning systems match your heat load so are ideal for professional
/ commercial areas that require a "set temperature" such as server
Evaporative air coolers are ideal for residential or light commercial
use such as a office.
