Eight Main Air Conditioner Parts and the way They Work

By Ian Parker


Right here is the collection of 8 major air conditioning parts and clarification of their key function in every air conditioning unit.

1. air-con or heat pump compressor which actually compresses low pressure refrigerant gas right into a very high pressure, warm temperature gas. In most cases the compressor is in the backyard segment of an air conditioning or heat pump device. The air conditioner or heat pump compressor device is actually a very high pressure pump driven by an electrical motor. The a/c compressor is usually packaged in the backyard compressor or condenser item.

2. A condenser or condensing element: typically a condensing coil contained within which high temperature very high pressure refrigerant gas flows, and over which a fan delivers air to chill the refrigerant gas back to a desired liquid form (and hence converting warmth from the refrigerant gas towards the air being exaggerated via the fan). The condenser device is basically a coil of finned tubing and a fan to blow air across the coil. Usually the condenser element is in the outside piece of an air conditioning system, in most cases packaged alongside the compressor pump mentioned above

3. A metering equipment which provides liquid refrigerant into an evaporator coil. The metering appliance could be simply a thin component of tubing or it may be a bit more refined thermostatic expansion valve which includes a temperature sensing control which could open and close the appliance against refrigerant flow.

4. An evaporator coil or cooling coil: generally the cooling coil is a element of finned tubing (it looks similarly to a car radiator) into which liquid refrigerant is metered and allowed to disperse from liquid to gas form contained in the coil. This state swap of the refrigerant, from liquid to gas, assimilates hot temperature, cooling the evaporator coil surface and thus cooling indoor air delivery across the cooling coil. In most cases the cooling coil is situated inside the air handler.

5. An air handler as well as blower item which provides a fan to distribute building air over or through the evaporator coil. The air handler blower fan element delivers building air across the evaporator coil surface with a purpose to condition building air by cooling it.

6. A duct structure which guides cooled or heated air from the air handler in to the office or bedroom space, and which takes air from the living area and returns it to the cooling system air handler.

7. Heat Pump Equipment utilise the same elements as explained above, with the addition of a reversing valve that fundamentally permits the unit to work backwards in winter period. Therefore in air conditioning mode the heat pump is shifting hot temperature from inside the building to outdoors whilst in heating mode the hotness pump is shifting high temperature from outdoor air towards the building interior.

8. Air conditioner controls that include an area thermostat, automatic switches, fuses or circuit breakers, condensate handling part, and air filtration systems.
