What does a vacuum pump do in a refrigeration system?

A vacuum pump's primary function in a refrigeration system is to remove air and moisture. This is crucial because the presence of air and moisture can lead to contamination, inefficiencies, and potential damage within the system. The vacuum pump creates a low-pressure environment, helping to eliminate these unwanted elements before the system is charged with refrigerant.

By removing moisture, the vacuum pump prevents ice and sludge formation within the system, which can cause blockages and reduce the overall efficiency and performance of the refrigeration cycle. It sets the stage for optimal operation by ensuring that the refrigerant can circulate freely and effectively.

In terms of operation and maintenance, achieving a proper vacuum is essential to ensure the long-term reliability and efficiency of the refrigeration system. This makes the vacuum pump an indispensable tool during the installation, servicing, and troubleshooting of refrigeration units.
