What effect does contaminated refrigerant have on a refrigeration system?

Contaminated refrigerant can significantly affect the performance and longevity of a refrigeration system. When refrigerant is contaminated, it may contain impurities such as moisture, acids, or foreign substances. These contaminants can lead to various issues within the system.

One primary effect is the premature wear of system components. Contaminants can cause damage to critical parts like compressors, evaporators, and expansion valves by creating blockages or facilitating corrosion. For instance, moisture can form acids when combined with refrigerant, leading to rust and deterioration of metallic parts. This can result in increased friction, overheating, and ultimately, failure of key components.

Moreover, the proper function of the refrigerant is essential for efficient heat transfer. Contaminants disrupt this process, leading to decreased efficiency and potentially leading to costly repairs or replacements. Understanding the importance of clean refrigerant is crucial for maintaining a refrigeration system’s health and operational efficiency.
