What happens to the refrigerant in a compressor?

In a refrigeration system, the compressor plays a crucial role in the refrigeration cycle. When the refrigerant enters the compressor, it is in a low-pressure gaseous state. The primary function of the compressor is to increase the pressure of this refrigerant gas.

As the refrigerant is compressed, its volume decreases and, as a natural consequence of the physical laws governing gases, its temperature rises. This process transforms the refrigerant into a high-pressure, high-temperature gas, which is essential for the next stage of the refrigeration cycle, where the refrigerant will reject heat to the outside environment through the condenser.

Understanding this process is foundational for anyone in the refrigeration field, as it highlights the compressor's vital function in facilitating the movement and transformation of refrigerant within the system. Knowing how processes like compression affect temperature and pressure is critical for troubleshooting and optimizing HVAC systems.
