What role do compressors typically play in a refrigeration cycle?

In the refrigeration cycle, compressors play a crucial role by increasing the pressure of the refrigerant. When the refrigerant enters the compressor, it is typically in a low-pressure gaseous state. The compressor draws in this low-pressure gas and then compresses it, which raises both its pressure and temperature. This pressurization is essential for the refrigeration cycle to function effectively, as it enables the refrigerant to carry heat from the space being cooled to the outside environment.

Once the refrigerant is compressed to a high-pressure state, it can then flow into the condenser, where it will release heat and change back into a liquid state. By increasing the pressure, the compressor sets the stage for the subsequent phases of the refrigeration cycle, allowing the system to continue efficiently transferring heat. This fundamental function of the compressor is why its primary role is to increase refrigerant pressure.
