The basic facts about air conditioning
Air conditioning for cooling
In this example of an air conditioning split system which comprises an indoor and an outdoor unit, connected
together by small copper tubing, in summer, the indoor unit extracts heat from the room and exhausts it via the outdoor unit through heat exchange coils and the
principle of pumped refrigerant gas.
Air conditioning for heating
In winter, the reverse occurs. Natural heat, which is present in the outdoor air - even when it's cold is
extracted and transferred indoors. Air conditioners that are able to heat and cool are known as heat pump systems. A heat pump system can be less expensive to run than
traditional central heating.
