Air Conditioner & Heating Repair System Operation

The experts at Feder’s Heating and Air Conditioning are pleased to share the following information that explains the major components of an air conditioning system and how an air conditioning system works.

One of the main components of a Amana, American Standard, Carrier, Coleman, Day & Night, Fedders, Goodman, Haier, Heil, Lennox, LG, Maytag, Payne, Rheem, Ruud, Soleus, Trane or York air conditioner unit is its pump compressor that compresses low pressure refrigerant gas into a high pressure, high temperature gas. Air conditioners compressor, as it is more commonly known, is in the outdoor portion of an air conditioning system, often found outside a bedroom window. This high technical compressor is a high pressure pump driven by an electric motor in a residential or commercial setting.

Another one of the main components of a unit setting it is a condensing coil through which a high temperature, high pressure refrigerant GAS flows, and over which a fan blows air to cool the refrigerant gas back to a LIQUID state (thus transferring the heat from the refrigerant gas to the air being blown by the condenser unit is basically a coil of finned tubing and a unit fan to blow air across the coil. It is the unit’s condenser that changes the state of the refrigerant from a hot high pressure gas to a cool liquid that releases the heat that was captured from the house (building) and releases it to the outside cooling the indoor rooms.

The air conditioning systems metering device has the responsibility of dispensing the liquid refrigerant into an evaporator coil. The unit’s metering device is sometimes a simple a thin section of tubing, also known as capillary and other times it is a thermostatic expansion valve that includes a temperature sensing control that is able to open and shut the device against the refrigerant’s flow.

One of the requisite equipment parts of the air conditioning system is the evaporator coil, also known as the cooling coil. The cooling coil is usually a section of finned tubing that looks like a car radiator in and it is here that the liquid refrigerant is metered and allowed to evaporate from a liquid condition to a gas condition inside the evaporator coil. This conditioning change from liquid to gas in which the coil absorbs heat and the cooling evaporator coil surface and then cooling indoor air is blown across the cooling coil.

The air handler and blower unit provides a fan to blow the room air (building air) across or through the evaporator coil. The air handler blowing unit fan moves the house air at across the evaporator coil surface in order to condition the house air by cooling it, and thereby removing the moisture from the cooled air.

The air conditioning system has a circular duct system that distributes the conditioned air from the air handler in to the occupied space of the supply ducts and that also takes the air from the occupied space and returns it to the cooling system’s air handler.

The last component of the air conditioner system are the controls that include a room thermostat, electrical switches, fuses and circuit breakers, a condensate handling system and air filters.
