Abstract
Abstract An indoor space environment heating and cooling system in which a massive thermal storage unit is interposed between a geothermal heat energy storage capacity--the earth--and a heat pump heating and/or cooling apparatus for controlling and maintaining the environment in an indoor living space. A fluid circulation apparatus is provided to circulate a working fluid from the massive thermal storage unit directly to a heat exchanger in the indoor space environment conditioning apparatus, to provide cooling when the temperature of the thermal storage unit is less than the temperature in the living space.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A geothermal system for heating and cooling the environment of indoor living space, comprising: (a) a massive thermal storage means; (b) a geothermal storage capacity means connected to the massive thermal storage means in a heat transfer relationship by a first subsystem comprising a closed circuit for conducting a working fluid between the massive thermal storage means and the geothermal storage capacity means as induced by a first pumping means in the closed circuit, the geothermal storage capacity means being the earth; (c) heat pump means operably connected to a first heat exchanger in the environment of the living space and operably connected to a second heat exchanger in the massive thermal storage means in heat exchange contact with the working fluid; and (d) a second subsystem comprising a closed circuit for conducting the working fluid between the massive thermal storage means and a third heat exchanger in the environment of the living space connected in heat exchange contact with the working fluid.
Claim 2
Dependent Claim
163 words
A geothermal system for heating and cooling the environment of indoor living space, comprising: (a) a massive thermal storage means; (b) a geothermal storage capacity means connected to the massive thermal storage means in a heat transfer relationship by a first subsystem comprising a closed circuit for conducting a working fluid between the massive thermal storage means and the geothermal storage capacity means as induced by a first pumping means in the closed circuit, the geothermal storage capacity means being the earth; (c) heat pump means operably connected to a first heat exchanger in the environment of the living space and operably connected to a second heat exchanger in the massive thermal storage means in heat exchange contact with the working fluid; and (d) a second subsystem comprising a closed circuit for conducting the working fluid between the massive thermal storage means and a third heat exchanger in the environment of the living space connected in heat exchange contact with the working fluid.
Claim 3
Dependent Claim
23 words
