It is approximately 2,740 kPa (27.9 kg/cm 2 , 397 psi) when the engine speed is less than 1,500 rpm. When it is approximately 120 kPa (1.2 kg/cm 2 , 17 psi) or less, ECM turns the A/C relay to OFF and stops the compressor. Pressure Relief Valve The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor. 2 , 526 psi)]. RJIA1552E |
