    摘要: A heat exchanger for use in a reversible refrigeration system. The exchanger is divided into a plurality of heat transfer zones containing one or more circuits. Control means are provided to route refrigerant through each zone in a series progression when the heat exchanger is serving as a condenser. The flow geometry is automatically changed when the function of the exchanger is reversed from condenser to evaporator so that refrigerant flows simultaneously through each of the heat transfer zones.

    摘要: A method and apparatus for controlling a multiple compressor heat pump system such that when the system is in the heating mode of operation the compressors are cycled individually depending upon the ambient temperature level and are individually co-ordinately operated in a defrost mode. The electrical control means disclosed provides for a second compressor being energized when the outdoor heat exchanger of a first compressor is being defrosted and the first and second contact means located within the individual defrost circuits for the first and second outdoor heat exchangers such that when the first outdoor heat exchanger is being defrosted the second outdoor heat exchanger may not commence a defrost cycle and when the second compressor is being operated in a defrost cycle a first compressor may not commence a defrost cycle.

    摘要: Apparatus and a method for providing a combination of non-reverse and reverse defrost for a refrigeration circuit are disclosed. A three-way valve is provided for initially circulating hot gaseous refrigerant directly from the compressor to the heat exchanger requiring defrost. An intermediate header is provided as part of the internal circuiting of the outdoor heat exchanger, said intermediate header serving to direct hot gaseous refrigerant from the three-way valve into all of the circuits of the outdoor heat exchanger simultaneously to effect defrost thereof. If, after a predetermined time period, the first mode of defrost directing hot gaseous refrigerant directly to the outdoor heat exchanger fails to accomplish defrost then the three-way valve is returned to its original position and the system is operated in a second defrost mode with the reversing valve being changed such that the system operates in the cooling mode and the outdoor heat exchanger serves as a condenser until defrost is completed. During the first mode of defrost, a liquid line solenoid valve is used to prevent the flow of refrigerant between the indoor heat exchanger and the outdoor heat exchanger.
