What is the purpose of using a pressure gauge in refrigeration systems?

The purpose of using a pressure gauge in refrigeration systems is primarily to assess the system's pressure and diagnose any potential issues. Refrigeration systems operate within specific pressure ranges, and monitoring these pressures helps technicians ensure that the system is functioning properly.

By checking the pressure readings on the gauge, technicians can identify if the refrigerant levels are adequate and whether the system is undercharged, overcharged, or experiencing any other abnormalities. This information is crucial for maintaining optimal performance, as deviations from the recommended pressures can lead to inefficiencies, compressor failures, or other operational problems.

Using a pressure gauge is an essential diagnostic tool in troubleshooting refrigeration systems, enabling technicians to make informed decisions regarding service and repairs to maintain system integrity.
