A heat transfer system for effecting heating and cooling at maximum system operating cost efficiency in both modes of operation. In a preferred embodiment, a solar collector is utilized to transfer radiant heat from the sun to a heat storage medium, such as water, which is circulated through a water coil of an indoor heat exchanger. A conventional heat pump has an indoor refrigerant coil supported in the same heat exchanger in thermal contact with the water coil. During heating or cooling, air is passed through the heat exchanger and the heat pump is used to supplement the circulating water when the water is insufficient for heating or cooling purposes. |
