  • Patent number: 6463755
    Abstract: An energy transfer system is provided for a household or commercial refrigeration appliance. The energy transfer system includes a fluid passage disposed in the housing of the appliance for enabling the transfer of a fluid into, through, and out of the housing. The fluid is circulated through a heat exchanger which can be disposed outside of a home or commercial building or underground so that the fluid is cooled by the outside air or by the ground. The cooling fluid is also utilized to cool the compressor of an air conditioning unit. A heat exchanger is also utilized for transferring heat from the cooling fluid to an interior of a building.
    Type: Grant

    Inventors: Amir L. Ecker, Joseph A. Pietsch
  • Patent number: 4320630
    Abstract: What is disclosed is an improvement in a heat pump water heater wherein the elements are disposed in a thermoplastic, molded base atop the hot water storage tank. The molded base has a drain for draining off liquid condensate. The condenser is in the form of a coil having the respective refrigerant and water paths for flowing in heat exchange relationship and disposed atop the hot water storage tank. The water has its own respective pump for being circulated through the condenser for heating the water while condensing the refrigerant. The evaporator is disposed peripherally around the top of the hot water storage tank so that the air that vaporizes the refrigerant is cooled and can be vented back to the air conditioned space. A self-supporting air filter is provided.
