How a Lewisville Air Condition System Works

Here is a easy answer on how a Lewisville air conditioning system works, with sufficient detail so that it is not rocket science . Your Lewisville air conditioner or heating pump has a compressor that compresses low pressured refrigerant into a high temperature, high pressure gas. Often the compressor is in the outside portion of the air condition or heat pump system. Basically, the compressor is a high pressure pump controlled by an electric motor. The air conditioning compressor is often packaged in the outside compressor/condenser unit.

A condensing unit is a condenser: basically a condensing coil inside which high pressure and high temperature refrigerant flows, and which a fan blows air and cools the refrigerant gas back to a liquid ( changing heat from the refrigerant gas to air blown by the fan). The condenser unit is mostly coil-finned tubing and a fan to circulate air across the coil. Basically the condenser unit is in the outside section of an air conditioning system, mostly packaged with the compressor motor mentioned before. The state of change of the refrigerant, from high pressure gas to a liquid blowing heat, such as heat compressed inside of a building to outside.

A metering device can dispense liquid refrigerant into an evaporator coil. The metering device can just be a thin portion of tubing (cap tube) or it can be a little more elaborate like a thermostatic expansion valve which haves a temperature censor control that open’s and closes against refrigerant flow.

The cooling coil and evaporating coil: mostly the cooling coil is a portion of finned tubing ( similar to a car radiator) which the liquid refrigerant is regulated and allowed to evaporate from liquid to gas inside the coil. This form change of in the refrigerant, from liquid to gas, attacks heat, cooling the evaporator coil surface, and cooling indoor air circulating across the cooling coil. Sometimes the cooling coil is installed inside the air-handler.

An air handler and blower unit provides a fan to circulate building air over and through the evaporator coil. The air handler fan unit circulates air across the evaporator coil surface to enable conditioned air by cooling it (removing moisture from cooled air).

A duct system circulates conditioned air from the air handler in the specified space (or supply ducts), and grabs air from the specified space and brings back the air to the cooling system handler.

Air condition features and controls include electrical switches, room thermostat, fuses or circuit breakers, air filters, and condensate handling system.
