Central Air Conditioning Systems

What is a Central Air Conditioning System?

A central air conditioning system is a popular cooling solution for homes. It provides efficient cooling to all rooms by utilizing a network of ducts and vents. The system comprises a central unit that cools the air and distributes it throughout the house.

How Does a Central Air Conditioning System Work?

A central air conditioning system works by drawing in warm air from the rooms, passing it through a cooling mechanism, and delivering cool air back into the living spaces. The central unit, typically located outside the house, contains a compressor, a condenser, and an evaporator coil.

The compressor pressurizes the refrigerant, raising its temperature. The hot refrigerant then flows to the condenser, where it releases heat and becomes a high-pressure gas. Next, the refrigerant travels to the evaporator coil, located inside the house.

Meanwhile, the warm air from the rooms is drawn into the return ducts and passes over the chilled evaporator coil. As the air comes into contact with the cold coil, heat is transferred, and the air is cooled. The cooled air is then circulated back into the rooms through the supply ducts and vents.
