How Home Air Conditioning Units Work

Nothing is nicer on the days highlighted by searing heat than returning to a cold and air-conditioned place. While we can always appreciate homemade air conditioning systems, very few of us know how the air miraculously keeps our houses cool in these mysterious boxes. 

It could intuitively seem that the domestic air conditioners work simply by refreshing the air entering your house. While this is one of the main aspects of your house’s air conditioning process, the heat removal process is another key aspect where the AC components work together to keep the air cold and the temperature at home controlled.

In both a home and a company, an air conditioner is a central heating and cooling system that provides cool air through sheet metal ductwork by drawing warm air inside and eliminating its heat, replaced by cooler air.

It could intuitively seem that the domestic air conditioners work simply by refreshing the air entering your house. While this is one of the main aspects of your house’s air conditioning process, the heat removal process is another key aspect where the AC components work together to keep the air cold and the temperature at home controlled.

The entire process of bringing the air temperature in your home to a comfortable level is based on a single scientific premise, with the rest being accomplished through mechanical means. In its most basic form, the air conditioning process entails two simultaneous processes, one within the residence and one outside. Let’s look at how air conditioning works to keep your home cool.

Warm indoor air is cooled as it blows past a cold cooling coil filled with refrigerant inside the residence (often referred to as the system’s “cold side”). As the refrigerant transitions from liquid to gas, heat from the indoor air is absorbed into it. The cooled air is re-circulated throughout the residence.

The refrigerant gas is pressurized outside the home (often referred to as the “hot side” of the system) before entering a huge coil in the outdoor unit. As the refrigerant returns to a liquid, heat is released outdoors, and a big fan draws exterior air through the outdoor coil, rejecting the heat collected from the house.

As a result, heat, and humidity are removed from interior air, cold air is returned to the residence, and heat and humidity are expelled.

Working of Air Conditioner in detail

Now that you have a fundamental grasp of how air conditioners work let’s go through the complete process in detail.

The thermostat monitors and controls the interior air temperature and is often located on a wall in a central area within the home. When the thermostat detects that the air temperature needs to be dropped, it signals the air conditioning system components to turn inside and outside the house.

Through return air ducts, the fan from the indoor unit sucks hot air from inside the house. Dust, lint, and other airborne particles are gathered as the airflow through filters. After that, the filtered, heated interior air travels through a cool evaporator coil. 

The heat from the indoor air is absorbed into the refrigerant as the liquid refrigerant inside the evaporator coil transforms to a gas, cooling the air passing over the coil. The cooled air is then pumped through the home’s ductwork and into the various living rooms by the blower fan of the indoor unit.

The refrigerant gas travels through a copper tube outside the house and into the compressor in the air conditioner unit. Imagine a huge electric pump as the compressor. The compressor compresses the refrigerant gas before sending it to the condenser coil on the outdoor unit.

Outdoor air is drawn through the condenser coil by a big fan, which allows the air to collect and release heating energy from home. The refrigerant is returned to a liquid during this procedure. It then returns to the indoor unit via a copper tube, passing via an expansion device that controls refrigerant flow into the evaporator coil. The cold refrigerant takes even more heat from the inside air, and the cycle repeats.

Role of each component of AC

Condenser Coil: In a split system HVAC, the condenser coil absorbs heat from the refrigerant and converts it to a liquid state, removing it from the system.

Refrigerant: The compressor in the air conditioning unit’s outer half transports this cooling liquid throughout the system.

Compressor: The compressor sends refrigerant to the condensing coil as a high-pressure gas in a literal compression operation.

Fan and Air Handling Unit: The condensing coil is cooled by a fan on the exterior component, while the internal fan blows cool air into your home.

Evaporating Coil: This liquid travels from the condensing coil to the evaporating coil in the indoor portion of the air conditioner. To transform the liquid back into a cooled gas, pressure decreases in the evaporating coil. The evaporating coil absorbs heat from within your home and sends it to the condenser, which restarts the cooling process.

Filters: In order to maintain good indoor air quality, a filter located in the inside half of the AC plays a key function in keeping dust and debris out of the building.

Thermostat: The air conditioning unit has a thermostat that allows you to set the temperature to your liking.
