What happens if non-condensable gases enter the refrigerant system?

When non-condensable gases enter the refrigerant system, they can lead to several issues, particularly posing a risk to the compressor. Non-condensable gases, such as air, do not condense under normal operating conditions, which can result in improper heat exchange and increased operating pressures. This can lead to overheating of the compressor, as it struggles to compress the gases efficiently, leading to potential mechanical failure or damage over time.

By disrupting the intended refrigerant cycle, non-condensable gases hinder cooling performance, which can exacerbate wear and tear on the compressor components, ultimately risking catastrophic failure. Therefore, understanding the detrimental impact of non-condensables is essential for maintaining system integrity and ensuring optimal operation.
