What is the primary purpose of pressure gauges in a refrigerant recovery system?

The primary purpose of pressure gauges in a refrigerant recovery system is to monitor system pressure and ensure proper operation. These gauges provide real-time readings of the pressure inside the recovery system, allowing technicians to assess whether the system is functioning correctly. By monitoring the pressure, technicians can determine if the refrigerant is present in the proper amounts and at the correct pressures necessary for effective recovery, thereby avoiding potential issues such as overcharging or undercharging the system.

This accurate pressure monitoring is critical to maintaining safe operations and ensuring that the recovery process meets legal and environmental regulations regarding refrigerant management. Understanding the pressure levels also helps in diagnosing issues within the system, ensuring that the recovery procedure is efficient and adheres to industry standards.
