In this blog post, we will delve into the inner workings of air conditioners and explain how they keep your home cool and comfortable even in the hottest of summers.

Refrigeration Cycle

Air conditioners work on the principle of the refrigeration cycle. It begins with the compressor, which pressurizes the refrigerant, usually a Freon gas. The high-pressure refrigerant then flows to the condenser coil located outside the house, where it releases heat and condenses into a high-pressure liquid.

Heat Exchange

The condensed refrigerant moves to the evaporator coil, situated inside the house. As warm indoor air blows across the evaporator coil, which consists of numerous small, intricate metal fins that help maximize the surface area for heat exchange. Then, the refrigerant absorbs heat energy from the surrounding air, effectively cooling the air passing through the evaporator coil. This cooled air is then distributed back into your living space, providing a refreshing and comfortable indoor environment.

Air Circulation

To ensure that the cooled air reaches all areas of your home, air conditioners employ a blower fan and a network of ducts. The blower fan is located in the air handler or furnace and is responsible for drawing air from your living space and forcing it across the evaporator coil.
Once the evaporator coil has cooled the air, the blower fan propels it through the ductwork system. The system of ducts consists of channels that are strategically designed to carry the conditioned air to different rooms in your home. These ducts are often hidden behind walls, in ceilings, or under floors, and they ensure that every part of your home receives cooled air.

Thermostat Control

The thermostat plays a crucial role in air conditioning systems. It allows you to set and maintain your desired indoor temperature. Once the temperature reaches the set point, the thermostat signals the air conditioner to turn off. When the temperature rises above the set point, the thermostat activates the cooling cycle again, ensuring a consistent and comfortable indoor environment.
