What is a common form of contamination in refrigeration systems?

Moisture and air are indeed a common form of contamination in refrigeration systems. When moisture enters a refrigeration system, it can lead to several problematic issues such as ice formation and corrosion of components, which can impair the efficiency and functionality of the system.

Air, when present in the system, creates non-condensable gases that affect the pressure levels and overall performance. The introduction of moisture and air can reduce the heat exchange efficiency, leading to decreased cooling performance and potentially causing damage that may require extensive repairs or system replacement.

Proper best practices in installation, maintenance, and servicing, including the removal of moisture from the refrigerant circuit and properly evacuating the system before charging with refrigerant, are critical to preventing this type of contamination. Thus, addressing moisture and air contamination is essential to ensure the longevity and efficiency of refrigeration systems.
