ABSTRACT:
Process and apparatus for control of the climatic environment of an underground enclosure having at least one source tending to emit a quantity of extraneous heat and associated with premises presenting a potential need for heating. Utilization is made directly of the regulating characteristics of the ground at a depth taking account of thermal inertia in order to enable the ground to operate as a heat source or thermal absorbent. For this purpose, apparatus is provided which is arranged entirely under the level of the ground at a mean depth which should not exceed 10 m, at latitudes in France, but this depth is variable according to the particular geological nature of the terrain. To take advantage of the thermal buffer the temperature of which is generally about 12.degree. C. in the Parisian region, the apparatus includes a wall structure with some of the walls formed of a material with a high coefficient of thermal exchange. The apparatus also includes an array of piping embedded in the walls together with means for circulating a refrigerant through the piping at low temperature, and a utilization circuit including an array of heat diffusers arranged in the premises to be heated, and a heat pump including an evaporator located in circuit of the piping and a condenser located in the utilization circuit. Shutters are also provided in the walls, and depending on their open or closed condition determines the transfer of heat through the lateral walls.
