What is the main purpose of the compressor in a refrigeration system?

The primary function of the compressor in a refrigeration system is to compress refrigerant gas and circulate it throughout the system. This process begins when the compressor takes in low-pressure refrigerant gas and increases its pressure. By doing so, the compressor effectively elevates the temperature of the refrigerant and sends it into the condenser.

The role of the compressor is crucial in the refrigeration cycle, which involves the continuous movement and transformation of the refrigerant. After the compressor has pressurized the refrigerant, it becomes a high-temperature, high-pressure gas that is then directed to the condenser, where it releases the heat absorbed from the evaporator to the surrounding environment. This cycle allows the refrigeration system to maintain the desired temperature within the cargo space or area being cooled.

Other components in the system have specific roles as well, such as absorbing heat or dissipating it, but the compressor is fundamental for maintaining the flow of refrigerant and facilitating the heat exchange process, which is essential for refrigeration to effectively cool an area.
