A condensing unit is an integral part of a refrigeration system or an air conditioning system. It is a mechanical device that is responsible for converting a high-pressure, high-temperature refrigerant gas into a liquid state.

The condensing unit

Typically located outside a building or a house, and it includes the compressor, condenser coil, fan, and controls.

The compressor

The heart of the condensing unit is the compressor and it is responsible for compressing the refrigerant gas, which raises its temperature and pressure.

The condenser coil

The high-pressure, high-temperature refrigerant gas then flows through the condenser coil, where it releases heat to the surrounding air or water, depending on the type of system.

As a result, the refrigerant gas condenses into a liquid state, which is then sent to the evaporator coil, where it absorbs heat from the air or water and cools it down.

The fan

The fan in the condensing unit is responsible for drawing air through the condenser coil and expelling it to the surrounding environment.

The controls

The controls in the unit are responsible for regulating the compressor, fan, and other components to maintain optimal performance and efficiency.

Overall, the condensing unit plays a critical role in the refrigeration cycle, and it is essential for keeping indoor environments cool and comfortable.
