Abstract
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 i…
