<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioning heat source device superior in energy-saving, electric power load leveling and system extension, by reducing work cost by making a geothermal heat exchange coil compact, by dispensing with an antifreeze, by preventing a large variation in the soil temperature when using geothermal heat. <P>SOLUTION: The geothermal heat exchange coil, a heat source machine and an air-conditioning heat pump (hereinafter referred to as an air conditioner) are connected by a circulating water pipe. The air conditioner gathers heat from circulating water, or stores heat in soil by the geothermal heat exchange coil by an over or short calorific value by exhausting the heat in the circulating water. A deviation from the natural temperature of the soil temperature generated as a result of this, is eliminated by heating control or cooling control of the heat source machine operated by mainly using night power, in addition to heat conduction (using geothermal heat) from surrounding soil or to the surrounding soil. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
