What’s The Difference Between Condenser Coils & Evaporator Coils?

The main difference between these two types of coils is their function, with condenser coils releasing heat from the refrigerant, while evaporator coils absorb heat from the environment. Both coils are essential for the proper functioning of a commercial refrigeration system.

Condenser Coils

Condenser coils are responsible for releasing the heat absorbed by the refrigerant during the cooling process. They are usually located on the outside of the refrigeration unit and are exposed to the ambient air.

The refrigerant enters the condenser coils as a hot, high-pressure gas and releases its heat to the surroundings, which causes it to condense back into a liquid. This liquid refrigerant is then sent to the evaporator coils to begin the cooling process again.

Evaporator Coils

On the other hand, evaporator coils are responsible for absorbing heat from the surrounding environment and transferring it to the refrigerant. They are usually located inside the refrigeration unit and are exposed to the air inside the cooling compartment.

The refrigerant enters the evaporator coils as a low-pressure liquid and absorbs heat from the surrounding air, causing it to evaporate into a gas. This gas refrigerant is then sent to the condenser coils to release the heat and complete the cooling cycle.
