  • Heating and cooling apparatus
    Publication number: 20070056311
    Abstract: A heating and cooling apparatus includes a compressor for pumping a heat medium through a tubing device, a primary heat exchanger coupled to the compressor, a control device coupled to the primary heat exchanger and coupled to a intermediate heat exchanger to control the intermediate heat exchanger either to dissipate heat or to absorb heat. Another control device is coupled to the intermediate heat exchanger and coupled to the compressor and a secondary heat exchanger, to control the heat medium from the intermediate heat exchanger either to flow through the secondary heat exchanger or to directly flow into the compressor without flowing through the secondary heat exchanger.
    Type: Application

  • Heating and cooling system
    Publication number: 20070056310
    Abstract: A heating and cooling system includes a compressor for pumping a heat medium through a tubing device, a heat exchanger coupled to the compressor for receiving compressed heat medium from the compressor, a flowing control device coupled to the heat exchanger, another heat exchanger coupled to the flowing control device and arranged to have the flowing control device coupled between the heat exchangers, and an air conditioner coupled to the flowing control device. The flowing control device may selectively couple the heat exchangers to the air conditioner and to the compressor, or selectively couple the heat exchangers together and to selectively couple the air conditioner to the compressor.
