GEOTHERMAL WATER ENVIRONMENT-PRESERVATION TYPE HEAT SUPPLY SYSTEM

PROBLEM TO BE SOLVED: To provide a geothermal water environment-preservation type heat supply system which effectively utilizes geothermal water for melting snow and cooling road surfaces, and returns the circulated geothermal water to an aquifer without making the water contact with the outside air as much as possible. SOLUTION: The system includes an exterior pipe 2 buried under the ground to the aquifer L holding geothermal water, a geothermal water permeation strainer 21 for making the geothermal water of the aquifer L permeate into the exterior pipe 2, a geothermal water pump-up pump 3 for pumping up the geothermal water which permeated in the exterior pipe 2, geothermal water supply piping 4 for circulating the pumped-up geothermal water in a predetermined site F as a heat source, a geothermal water returning strainer 22 for returning the geothermal water which has circulated in the geothermal water supply piping and is returned into the exterior pipe 2 to the aquifer L, a reservoir tank 5 for collecting and reserving melted snow water, rain water, and sprayed water, etc., generated in the site F without making them flow to the outside of the site F, a water spray means 6 for spraying water in the reservoir tank 5 to the site F, and a geothermal water refilling mean 7 for suitably supplying the geothermal water as water for spraying from the geothermal water supply piping 4 to the reservoir tank 5.
