what is the difference between air conditioners and evaporative coolers

One of the most frequent questions we get is what is the difference between air conditioners and evaporative coolers?

We have both for hire but we need to understand your needs before we can recommend a machine for you.

Air Conditioners

The portable air conditioners we hire are refrigerant machines. They are a smaller portable version of the internal wall mounted unit which has a pipe connected to an outside condensing unit.  As these machines use a refrigerant and a condenser they are very efficient at producing chilled air. The air out of our portable air conditioners is usually between 5 c and 10c.

How To Use Our Air Conditioners

In order to cool the room, the hot air must be removed through the air hose. The air hose needs to be placed through a window or door.

Evaporative Coolers

The evaporative coolers we hire work like a breeze over a lake or river.  The hot air from the room is pulled across a wet filter.  The heat of the air evaporates the water on the filter which cools the air. The cool air is then pushed back out into the room.

Evaporative coolers have a tank of water which needs to be constantly topped up.

These types of coolers work best in areas with a constant supply of fresh low humidity dry heat.

What are BTU’s and KW’s?

BTU’s and KW’s are different units of measure of heat or cooling energy. Here in the Ireland sometimes we use British Thermal Units (BTU’s) as a way of measuring heating and cooling machine performance. The internationally recognised unit of Kilowatts (KW) is also used to measure heating and cooling performance. There is a direct relationship between the two – 1KW is the equivalent of about 3400BTU. So a 9000BTU machine is a 2.6KW machine.
