What does the purge system do in a refrigeration system?

The purge system in a refrigeration system plays a crucial role in maintaining the integrity and efficiency of the system by removing non-condensable gases and water. Non-condensable gases, such as air, can accumulate within the refrigeration system, leading to several negative effects, including reduced efficiency, increased operating pressure, and potential safety hazards. Water can also enter the system either through leaks or other means and can lead to corrosion and decreased performance.

By effectively purging these unwanted substances, the system can operate within its optimal parameters, ensuring that the refrigerant cycle functions properly. This process helps maintain the correct pressure within the system and allows for efficient heat exchange, which is vital for the overall performance of the refrigeration system. Therefore, the primary function of the purge system is indeed to remove non-condensable gases and water, helping to sustain the operational efficiency of the refrigeration system.
