How Do Air Conditioners Work?

“How do air conditioning units work?” To sum it up, air conditioning devices eliminate heat and humidity from the atmosphere inside your home and transport it outside to cool things down.

To complete this process, many different parts of the air conditioner must work together in harmony. And don’t forget that various air conditioning models serve the same purpose of cooling your home. Therefore, before installing an air conditioner at your place, it is better to consult professionals for Columbia, MD air conditioning installation service to understand which system is best for you.

How does an air conditioning unit work?

Air conditioning units come in all shapes and dimensions, but they all work on the same basic principle. In addition, cooling devices offer cold air within your home or enclosed area by expelling heat and humidity from the ambient air. It returns cooled air to the interior while transferring undesired heat and humidity outside.

A typical air conditioner or cooling system employs a specialized chemical known as refrigerant and consists of three major mechanical parts: a compressor, a cooling coil, and an evaporator coil. These pieces fit together to transform the coolant from gas to liquid and back as quickly as possible. The compressor increases the pressure and temperature of the cooling medium before sending it to the condenser coil to be transformed into liquid.

The refrigerant then returns indoors and reaches the evaporator coil. The cooling fluid evaporates here, cooling the indoor coil. A fan circulates indoor air across the cold evaporator coil, where the refrigerant absorbs heat from the house. The cooled air is then distributed throughout the house, while the warmed evaporated gas gets returned to the compressor outside.

How does a cooling system work in detail?

The thermostat displays and restricts the temperature of the filtered air, and you can readily install it on a wall in a centralized location within your place. When the thermostat detects that it must lower the air temperature, it sends messages to the air conditioning system elements inside and outside the home to begin operating. The fan on the indoor unit draws hot air from the house via return air ducts. This air gets routed through filters, which collect dust, dirt, and other airborne particles.

The filtered, warm indoor air passes over the cold exchanger coil. The heat from the ambient air is assimilated into the coolant as the refrigerant vapor inside the heat exchanger coil converts to gas, cooling the air as it passes over the coil. The chilled air is then pumped back through the home’s ductwork by the indoor unit’s blower fan and into the various living spaces.

The refrigerant gas exits the house via a copper tube and enters the compressed air in the outdoor air conditioner unit. Consider the compressor to be a large electric pump. The compressor compresses the refrigerant gas and directs it to the outdoor unit’s condenser coil.
