It is referring to the heart of the vapor compression system (as we discussed earlier).

The main function of the compressor is to draw the vapors of the refrigerant from an evaporator so that a minimum temperature and pressure can be maintained in the evaporator.

As a result, the purpose of boiling the refrigerant by extracting the heat from the objects that are placed within the evaporator can be fulfilled.

The compressor then has to raise the temperature of the vaporized refrigerant up to a level, so that the condensation of the refrigerant can occur by rejecting the heat to the cooling medium in the condenser.


Classification of Compressor

A typical classification of the compressor is given below. Different types of compressors are used for different purposes.

Classification of Compressor

Generally, the life of the compressor is considered to be about 10 years. But this figure may change dramatically and can only depend upon the working conditions.

As many reasons may affect the life of the compressor. Burnouts occur when a spark takes place in the compressor. This spark may burn the entire compressor and refrigerant also.

The presence of a huge amount of refrigerant or moisture may lead to additional stress on a compressor and causes it to fail permanently.

It is important to note here that the start and stop option of the compressor is working frequently, it means if the compressor starts and stops very frequently, it may lead to compressor failure permanently.

Because each start and stop operation puts additional stress on the compressor. That’s why during the supply of fluctuating power, it is advisable to turn off the refrigerator.
