Why are pressure gauges critical in refrigeration?

Pressure gauges are critical in refrigeration because they provide essential information about the performance of the refrigeration system. By measuring the pressure of the refrigerant in various parts of the system, technicians can determine if the system is operating within the correct parameters.

When a technician reads the pressure gauges, they can identify whether the refrigerant charge is appropriate, whether the compressor is functioning correctly, and if there are any leaks or blockages in the system. These readings allow for accurate diagnosis and troubleshooting of potential issues which is key to maintaining efficiency and preventing breakdowns. Therefore, the ability to assess system performance and detect issues through pressure gauges is vital for the reliability and effectiveness of refrigeration systems.
