Air Conditioning & Air Cooling

What is the difference between air conditioning and air cooling?

Air Conditioning

An air conditioning unit quickly and efficiently lowers the indoor temperature during the warmest periods of the year. It works under the same principle as a fridge, where a liquid refrigerant is fed into a evaporation system under low pressure. The low pressure makes the refrigerant evaporate into a gas, which cools the unit’s fins. The large surface area of the fins lowers the temperature of the air as it is blown over them and out into the room.
The air conditioning unit is operated with a compressor that is used to transform the gas into liquid again. It is this process which generates heat, which is fed out into the open air with a fan. For larger installations, this typically happens through a fixed installation in the wall. With the portable units this is avoided. Instead, the hot air is discharged for example through a window.

Air Cooling

Air cooling is natural cooling and can best be compared with a light breeze over a lake. An air cooler cools the air through the evaporation of water. When the water evaporates air and water molecules split up. The process requires heat, and that heat is retrieved from the air, whereby the temperature is lowered.

With the use of an air cooler, windows and doors must be open and an air cooler works best when placed by an open window. The air cooler circulates the cooled air out into the room, where it again disappears out through the open doors and windows. An air cooler is therefore not air conditioning, which uses a compressor. An air cooler will not be able to achieve the same low temperatures. On the other hand, there are many other advantages:

  • Lower purchase price

  • Lower energy consumption

  • Environmentally friendly (no gas)

  • Maximum mobility

  • Low maintenance costs

  • No fixed installations

  • Cooling of open spaces

Wood’s has both mobile air conditioners and air coolers in its range. See the different models in the menu to the left.
