How Air Conditioning Units Work

By Paul Myers


Air Conditioning systems are installed usually due to a requirement to create comfortable living or working conditions. The Air Conditioning industry has never been large in the UK in comparison with warmer countries elsewhere in the world. The onset of global warming however seems likely to completely transform the market for air conditioning in the UK.

A 240 volt electric supply is needed to power the fan units in each room and an external compressor. Mounted wall units will be discreetly fitted in each room. These will be connected with a series of thin copper pipes to a small external compressor unit to allow the flow and return of refrigerant gas.

A typical domestic air conditioning system comprises of wall mounted units in each room with a small compressor unit mounted externally. The two components are then linked with a pair of thin copper pipes which provide for the flow and return of refrigerant gas. A 240v electric supply then drives the fan unit in the room and the external compressor. Typically a remote control (like a TV remote) is then used to control the system for on/off, temperature and fan speeds.

The internal wall mounted unit is alternatively referred to as a wall inverter unit or high-wall inverter. The advent of inverter technology has transformed the efficiency of air conditioning. Its general application is in digitally controlling the capacity and fan speed of the system to match it precisely to the temperature to be maintained or achieved.

Some air conditioning units on the continent and in holiday destinations give the systems a bad name, as they are often extremely noisy and ineffective. But this shouldn't prevent you from considering an air-con system for your home. Modern systems are so quiet if sited in the right place that they will not disturb your home or the residential area that you live in.

Air conditioning systems have the ability to effectively be 'run in reverse', thereby also acting as a heat pump. This is an extremely efficient use of electricity in providing domestic heating by provision of warm blow air. As a guideline the cost indication would be that a single wall inverter unit and compressor can be supplied and fitted at under 2000 +vat.
