A solar-assisted multiple source and multiple sink heat pump system for use in residential homes includes a solar/air coil mounted in the attic of the residential home and selectively open to the attic interior with the attic roof bearing a solar window with selective shield permitting the attic solar space to constitute a passive solar collector. The solar/air coil is positioned within duct work which selectively opens to the attic interior or the outside air to permit thermal energy pick up from the attic solar space or outside air or wasting of heat thereto. The inside air coil is also mounted in a separate duct work within the attic shielded from the attic interior but selectively open thereto and to and from the building interior beneath the attic for adding heat to the building interior or removing the same. One or more thermal storage tanks may constitute heat and cold sinks. Energy amplified by the heat pump may be delivered to inside air, a domestic hot water heater within the building, hydronic heating system water within the building space to be conditioned, the storage system tank media, or alternatively discharged to the outside air through the solar/outside air coil in the case of net requirement for rejection to ambient through the heat pump system. Direct room heating from the solar space or cooling by outside air flow is achieved without heat pump operation, and free-wheeling to and from storage media is provided.

A heat pump refrigeration system for conditioning a residential building space or the like, said building comprising an attic thermally isolated from the space to be conditioned, said attic including a solar window facing a solar radiation source such that said attic defines a passive solar collector and forms a solar space, said refrigeration system comprising: a first heat exchange coil; a second heat exchange coil, said coils trading functions as evaporator or condenser to absorb heat and discharge heat, respectively; a compressor; conduit means carrying refrigerant and defining a closed refrigeration loop circuit including said coils and said compressor and further comprising means for selectively operating said first and second heat exchange coils as evaporator or condenser as required, the improvement comprising: a first duct within said attic, said first duct housing said first coil and having an inlet and an outlet; a second duct within said attic and thermally isolated from said first duct, said second duct housing said second coil and having an inlet and an outlet; blower means for forcing air flow through said ducts; means for selectively communicating said first duct inlet and outlet to the building exterior or to said attic solar space; said second duct outlet opening into the building space to be conditioned; and means for communicating said second duct inlet to at least said space to be conditioned, whereby said first coil functions to pick up heat from said solar space or from said outside when functioning as system evaporator or to discharge heat to the outside when functioning as system condenser, and said second coil functions to heat or cool the space to be conditioned when functioning as condenser and evaporator, respectively.
