  • System and method for controlling the discharge temperature of a high pressure stage of a multi-stage centrifugal compression refrigeration unit
    Patent number: 4262488
    Abstract: A system for controlling the discharge temperature of a high pressure stage of a multi-stage centrifugal compression refrigeration unit includes flow control means for maintaining a continuous flow of refrigerant through the high pressure stage regardless of changes in the heating load thereon. When the heating load on the high pressure stage decreases below a predetermined level the pressure at the suction side of the high pressure stage is substantially reduced to decrease the weight flow of refrigerant through the high pressure stage. Simultaneously, the pressure differential across the high pressure stage is substantially equalized.
