System Specifications

R-134a Pressures:





The low pressure is maintained in the refrigerant system by the variable displacement compressor throughout changing conditions and varying engine speeds (RPM).





The pressure relief valve is mounted on the compressor. At approx. 38 bar (551 psi), the valve opens to vent excessive pressure. When system pressure is reduced to approx. 30-35 bar (435-508 psi), the valve closes to prevent total refrigerant loss.
