All good air conditioning is based on precise control of temperature, humidity and air flow.
Air is cooled or heated by circulating it through an air conditioning unit (the heat exchanger) prior to its controlled discharge into the room via an indoor unit.
Criteria to be considered would include geographical location of building, U values (thermal insulation at build), room size & number of people working or living within the area.
Also, the type of equipment in use within the environment like, photocopiers or computers. These will give off heat so suitable locations for equipment would ensure maximum benefit is obtained. And of course, power supply.
For the various systems we can install, please refer to Air Conditioning Design Options
When an area becomes hot, the heat is absorbed by refrigeration liquid, sealed within the air conditioning system.
As the refrigerant absorbs the heat from the room, it becomes gas and passes through small copper tubes to the condenser outside and is released into the atmosphere.
The gas then changes back into a cold liquid, returned to the indoor unit, where the air is fanned over it, sending cool air back into the room. This cycle is repeated in order to maintain the temperature required.
Air conditioning units fitted with heat pumps allow the cooling process to be reversed to allow heating.
A heat pump extracts ‘free’ heat from the outside air, even when the temperature is as low as -10°, and then transfers this heat indoors.
Heat pump units avoid the need for a boiler, and allow cooling and heating within the same unit, thus enabling cost savings on energy throughout the year.
Air conditioning will heat an area faster than a conventional heating system.
