Main Components of a Refrigeration System

 In both commercial and residential sectors, refrigeration systems are crucial because they provide cooling or maintain a specific room temperature. With a refrigerant flowing through the units, a refrigeration cycle entails heat exchange, compression, and expansion.

The cold room's refrigeration system keeps it running. It is only a method of moving heat from one location to another. The technique of refrigeration that is most frequently utilized is the vapor-compression system. It is widely employed in sizable cold spaces, such as commercial chillers.

The condenser, compressor, evaporator, and expansion valve are the four basic parts of a refrigeration system.

Condenser

Gases become liquids by condensation. Its primary function is to liquefy the refrigerant gas that the compressor has drawn out of the evaporator. When condensation starts, heat will only transfer from the condenser into the air if the condensation temperature is higher than the ambient temperature. With the addition of some heat, the high-pressure vapor in the condenser will be cooled and transformed back into a liquid refrigerant. Condenser to liquid line flow of the liquid refrigerant will then occur.

Compressor

The purpose of the compressor is to draw low-temperature, low-pressure vapor from the evaporator using a suction line. It will be crushed when the vapor is extracted. The temperature increase will result from the vapors. Its primary job is to raise pressure by changing a low-temperature vapor into a high-temperature vapor. The compressor discharge line receives the emitted vapor.

Evaporator

Any liquid substance may be transformed into gas using an evaporator. Heat is taken in during this procedure. A liquid refrigerant, which boils in the evaporator at low pressure, transports heat from the refrigerated compartment into a heat pump through the evaporator. The liquid refrigerant should be lower than the objects being cooled to achieve heat transfer. Following the transfer, the compressor draws the liquid refrigerant from the evaporator through a suction tube. When liquid refrigerant exits the evaporator coil, it is in the form of vapor.

Expansion Valve

The expansion valve, which is frequently positioned before the evaporator and at the liquid line's terminus, is where the liquid refrigerant arrives after condensation. Its temperature will drop to a level below its atmosphere when the refrigerant's pressure is reduced. Following that, the evaporator will be pumped with this liquid.
