Central Air Conditioning

How it works

Central air conditioning systems are designed to cool an entire home or building by circulating cool air through a network of ducts. These systems typically consist of an outdoor unit, which contains the compressor and condenser coils, and an indoor unit, which includes the evaporator coils and blower fan. The indoor and outdoor units are connected by a series of ducts, which allow the cool air to be distributed throughout the building.

When the system is turned on, the compressor pumps refrigerant through the system, which absorbs heat from the indoor air as it passes through the evaporator coils. The refrigerant is then compressed and sent to the outdoor unit, where the heat is released as the refrigerant passes through the condenser coils. The cool air is then distributed through the ducts to the indoor unit, where it is blown out into the room.

Advantages

One of the main advantages of central air conditioning systems is their ability to cool an entire home or building with a single unit. This can be particularly beneficial for larger homes or buildings, as it eliminates the need for multiple air conditioning units. Central air conditioning systems are also typically more energy efficient than window units, as they can more effectively regulate the temperature of the entire building.
