ABSTRACT:
An earth type heat pump having a heat exchanger including an evaporator coil and a compressor, condenser, receiver and expansion valve in series with the evaporator coil for delivering heat picked up at the heat exchanger from the condenser, and heat pickup tubes positioned vertically in the earth and connected with the heat exchange structure for passively supplying heat from the earth to the heat exchanger by means of a refrigerant passing between the heat pickup tubes and heat exchange structure, and the corresponding method of supplying heat from an earth type heat pump. In one modification the heat of the earth is supplemented by a solar heating system including a collector and heater tubes connected to the collector positioned vertically and interspersed with the heat pickup tubes of the heat pump. In another modification of the invention, heat transfer between the vertically positioned tubes is promoted by structure for and the method of moistening the earth around the vertical heat pickup tubes and the heater tubes.
