    • A vapor compression air conditioning system (100, 200) that reduces power consumption during peak demand periods is characterized by four refrigerant circuits. A first circuit includes a compressor (12), a first heat exchanger (22) and a second heat exchanger (28). A second circuit comprises the compressor (12), the first heat exchanger (22) and a third heat exchanger (102). A third circuit comprises the third heat exchanger (102), a refrigerant pump (104) and a thermal energy storage unit. A fourth circuit includes the thermal energy storage unit, the refrigerant pump (104) and a fourth heat exchanger (118). The first heat exchanger (22) is an outdoor heat exchanger. The second and fourth heat exchangers (28, 118) are indoor heat exchangers in heat transfer relationship with the fluid to be cooled or heated. A first refrigerant is circulated in the first and second circuits by the compressor (12). A second refrigerant is circulated in the third and fourth circuits. The system (100, 200) is operable in plural cooling and heating modes.

    • The invention entails the use of a positive displacement pump (41) magnetically coupled to a drive motor (42) located in a conduit arrangement (60) which is parallel to the liquid line (22) of the refrigeration system as in Fig. 5. This parallel conduit arrangement (60) also includes a pressure regulating valve (45) that will regulate the amount of pressure added to the liquid line (22) by the parallel pump and piping arrangement (60). In addition, a check valve (47) is located in the liquid line (22) to maintain the pressure differential added to the liquid line. This parallel piping arrangement (60) is desirable in order to allow a constant predetermined pressure to be added to the liquid line regardless of variations in flow rate of the liquid refrigerant. The present invention involves the use of a controlled variable speed drive on the pump meter so the flow rate through the pump will more closely match the variable system flow.
    • 本发明需要使用磁力耦合到位于如图1所示的制冷系统的液体管线(22)的导管装置(60)中的驱动马达(42)的容积式泵(41)。 该平行导管装置(60)还包括压力调节阀(45),其通过并联泵和管道装置(60)来调节加到液体管线(22)上的压力的量。 此外,止回阀(47)位于液体管线(22)中,以保持加到液体管线上的压力差。 这种平行管道装置(60)是期望的,以便允许将恒定的预定压力添加到液体管线,而与液体制冷剂的流量的变化无关。 本发明涉及在泵表上使用受控变速驱动器,使得通过泵的流量将更可靠地匹配可变系统流。

    • A reheater (46) is used in air-conditioning system which includes a compressor (12), a condenser (14), an expansion device (16), and an evaporator (18), interconnected by conduits in a closed loop. A centrifugal pump (32) boosts the pressure of the condensed liquid refrigerant by an incremental pressure sufficient to pressure subcool the refrigerant. A reheater (46) adjacent the evaporator and coupled to an outlet of the centrifugal pump receives pressure subcooled liquid refrigerant and cooled air from the evaporator to further subcool the liquid refrigerant below its condensing temperature and partially reheat the cooled flow of air thereby decreasing the relative humidity of the air. A reheater bypass conduit (33) is coupled between an inlet of the evaporator and the outlet of the pump, with bypass control valves (35A, 35B) to control the flow of liquid refrigerant responsive to climate control apparatus (39).
