Refrigeration & Air Conditioning
Refrigeration & Air Conditioning
Refrigeration is designed to cool an immediate area. It does this by using pipes filled with coolant – usually an F gas – which it forces from a liquid into a gas in order to create the cooling effect inside the fridge or chill room. A compressor then increases the pressure and temperature to turn the gas back into a liquid so that the process can be repeated, but not before putting the coolant through a condenser. The coolant constantly flows throughout the maze of tubing to help remove heat and keep temperatures low in a confined space.
Air conditioning uses the same principle of using a coolant already built into the system, but it also uses the ambient air in the room as part of the process for heating. Air conditioners, unlike conventional fridges, will have lots of ductwork and fans to push the hot or cold air around a building – and away from the unit – to achieve the right temperature over a much larger space. It removes heat and moisture to create a more comfortable working space when cooling, unlike in refrigeration.
