How An Air Conditioner Works?

Imagine enduring a hot, humid Lexington summer without a functioning air conditioner. The temperature, humidity, and overall air quality may all be altered by using an air conditioner. An air conditioning system, more specifically, cools your room by extracting heat energy from within and sending it to the outdoors, then replenishing the air in through colder air.

The process of air conditioning is twofold; inside the house and outside the house.

Within The House

Warm, humid air is chilled as it passes through a refrigerant-filled cooling coil. As the refrigerant transitions from liquid to gas, heating from the interior air is absorbed. The chilled air is recirculated throughout the home.

The thermostat detects and regulates the internal air temperature and is generally installed on a panel in a central area within the household. When the thermostat detects that the ambient temperature has to be decreased, it sends the signal to the air conditioner units both in and out of the house to turn on. However, the thermostat may cause a problem in signaling correctly sometimes. In that case, contact an AC repair Lexington KY.

The fan from the air conditioning unit draws hot air from within the home through exchange air ducts. Dust, dirt, and other small particles are captured when the air flows through filtration. After that, the filtered, heated interior air flows over the cold evaporator coil. This filter and coil can be replaced if not working. Just contact an air conditioning replacement Lexington KY.

Hot air from the indoor space is absorbed into the refrigerant as the liquid refrigerant within the evaporator coil changes to gas, reducing the temperature as it travels over the coil. The cooled air is then pumped back via the living area ducting and into the different living spaces by the indoor unit’s blower fan. 

Outside The House

The refrigerant gas flows via a copper tube just outside of the house and into the engine of the air conditioning system. During air conditioning installation Lexington KY, there is a compressor installed. Consider the compressor to be a significant electric pump. The compressor compresses the refrigerant gas and transfers it to the condenser on the outside unit.

Outdoor air is drawn through the copper tube by a powerful fan, causing the system to collect and release thermal energy from the residence. The refrigerant is turned back to a liquid during this procedure. It then returns to the indoor unit through a copper tube, passing through an expansion mechanism that controls the flow of refrigerant into the evaporator. After that, the cold refrigerant absorbs excessive heat from the air indoors. This cycle continues throughout the entire functioning of the AC unit. If it does not, then consider an AC repair company near me.
