High Pressure Safety Valve HVAC: Description and Operation
DESCRIPTION
The compressor is equipped with a pressure relief valve which is placed in the system as a safety factor.
OPERATION
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 3036 kPa (440 psi). Any condition that causes this valve to open should be corrected, and the
refrigerant oil and refrigerant should be replaced as necessary.
