Copper Tube Fin Coil for AHU

The coil in an air conditioning unit is a key component used to transfer heat in the cooling and heating cycles. The type and function of coils depend on their location and purpose in the air conditioning system.

Condenser Coil.

A condenser is a type of coil in an air conditioning system that is located outdoors.

In the cooling cycle, high pressure, high temperature refrigerant gas flows from the compressor to the condenser.

In the condenser, the refrigerant gas gives off heat and turns into a high-pressure liquid.

This process releases heat from the air conditioning room into the outdoor environment.

The condenser is usually surrounded by an exhaust fan to help dissipate the heat.

Evaporator Coil.

The evaporator is another type of coil, usually located indoors.

During the heating cycle, refrigerant liquid passes from the evaporator to the compressor.

The refrigerant in the evaporator absorbs heat from the indoor air and turns it into refrigerant gas.

This process lowers the temperature of the indoor air.

The air conditioning unit transfers the refrigerant gas through the cycle to the condenser and then back to the evaporator again.

Function and Role.

The function of the condenser and evaporator coils is to change the state of the refrigerant at different temperatures and pressures to fulfil the cooling and heating functions in the air conditioning cycle.

The condenser radiates heat to the outdoors, while the evaporator absorbs heat to cool the indoor air.

The design of the coil is critical to the efficiency and performance of an air conditioning system. A good design improves energy efficiency and reduces energy consumption.
