When the outdoor condensing pressure is lower than the designed opening
pressure of the condensing pressure regulator valve, the regulator valve closes
and the differential pressure valve opens. The refrigerant at the compressor
outlet is bypassed to the liquid storage unit of the low temperature
component through the differential pressure valve, ensuring that the
condensing pressure stays within a safe and reliable operating range.
When the condensing pressure is higher than the designed opening pressure
of the condensing pressure regulator valve, the regulator valve opens and the
differential pressure valve closes. The refrigerant at the compressor outlet
flows to the liquid storage unit of the low temperature component through
the condenser, and the system runs properly.
