Huawei NetCol8000-A045D - Water-Cooled Module

● When the outdoor condensing pressure is lower than the designed opening
pressure of the condensing pressure regulator valve, the regulator valve closes
and the dierential pressure valve opens. The refrigerant at the compressor
outlet is bypassed to the liquid storage unit of the low temperature
component through the dierential 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
dierential pressure valve closes. The refrigerant at the compressor outlet
ows to the liquid storage unit of the low temperature component through
the condenser, and the system runs properly.
