What type of pressure change does a compressor create in a refrigeration system?

In a refrigeration system, the compressor plays a crucial role in the refrigeration cycle by altering the pressure of the refrigerant. It primarily increases the pressure of the refrigerant gas drawn in from the evaporator. When the refrigerant vapor enters the compressor, it is at a low-pressure state. The compressor then compresses this gas, which leads to a significant increase in pressure.

However, within the entire refrigeration cycle, the system also operates on differing pressure levels. While the compressor increases the pressure of the vapor, it is essential to acknowledge that the process begins with low-pressure gas in the evaporator. Hence, the refrigeration cycle involves both low and high-pressure states.

By recognizing both the creation of high pressure and the initial low-pressure condition from the evaporator, it's evident that the compressor functions to facilitate pressure changes throughout the system. This dynamic illustrates how integral the compressor is in maneuvering the refrigerant between various pressure states, supporting efficient refrigeration processes.
