The removal of non-condensables, moisture, and other contaminants from a refrigeration system is a critical step in its installation, maintenance, and repair. This process prepares the system for optimal refrigerant charge and efficient operation by creating a clean, dry, and contaminant-free environment. For instance, a system improperly prepared can experience significantly reduced cooling capacity and increased energy consumption.
The absence of these detrimental elements is paramount to the system’s long-term performance and reliability. Moisture, for example, can react with refrigerant and oil to form acids, which corrode internal components and lead to compressor failure. Non-condensables, such as air, raise the system’s operating pressure, increasing stress on the compressor and reducing its lifespan. Historically, recognizing the impact of these contaminants has driven advancements in vacuum pump technology and procedures, improving overall system efficiency and durability.
