초록 ▼

A heating and cooling system is provided which includes a reversible heat pump with three refrigerant coils, one of which is in an air duct for the space to be served, another of which is in heat exchange relation with outdoor air, and a third of which is adapted to exchange heat with a heat exchange fluid which is circulated from a heat storage location, the system including valve means in the refrigerant lines for connecting any of the three coils to operate as either an evaporator or a condenser and for connecting either one of the other two coils to operate as a condenser or evaporator, respectively, so that heat can be exchanged in any combination between air in the duct serving the space to be heated, outside air, and the storage fluid. The system also preferably includes a solar collector and a second fluid storage tank, and circulating means and fluid valve means as well as a fluid-to-air heat exchanger in the duct so that heat from solar insulation may be used to heat directly or placed in storage, or heat may be provided for the space directly from the storage. Heat from storage may also be used with the heat pump operating. Various other modes of heat pump operation are also available in a cooling operation. The system also includes the provision of a diverting valve arrangement for the three coil heat pump which precludes, through a physical blocking arrangement, the possibility of short circuiting the discharge from the refrigerant compressor to the suction side of the compressor.
