Patent ID: 8099972

Claim:
Heating and/or air conditioning device for a home or other space, including a heat pump ( 3 ) thermally coupled to a buried heat exchanger ( 6 ), wherein: the heat exchanger ( 6 ) is contained in a buried thermal storage tank ( 1 ), the thermal storage tank ( 1 ) includes an underground pocket ( 1 a ) containing a permeable material ( 1 b ) and water ( 1 c ), further including: means ( 33 , 38 ) for exchange of heat with the indoor atmosphere of the space to be heated and/or means ( 26 ) for exchange of heat with a domestic hot water circuit, a heating circuit ( 35 , 36 , 28 ) using an intermediate heat exchange fluid and an intermediate circulator pump ( 32 , 34 , 25 ), means ( 31 , 24 ) for controlling the flowrate of the intermediate heat exchange fluid to provide selective thermal coupling of the heat exchange means ( 33 , 38 , 26 ) via the intermediate heat exchange fluid either with the heat pump ( 3 ) or with other collectors such as solar collectors ( 2 ) or atmosphere heat exchangers.
