High Pressure Safety Valve HVAC: Description and Operation
V-5 Compressor Mounted Control Switches (VIN U)
PRESSURE RELIEF VALVE
The compressor is equipped with a pressure relief valve which is placed in the system as a safety factor. Under certain conditions, the refrigerant on
the discharge side may exceed the designed operating pressure. To prevent system damage, the valve is designed to open automatically at
approximately 3173 kPa (468 psi). Conditions that might cause this valve to open (defective high pressure cut-off switch, inoperative electric cooling
fan, etc.) should be corrected, and the refrigerant oil and refrigerant should be replaced as necessary.
