Problems solved by technology

[0002] So far, although it has been considered to use underground water (warm water) for snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding, etc., it has not been actively implemented in practice because a large amount of water is extracted. Groundwater will cause foundation subsidence and other problems

Embodiment Construction

[0009] Based on the detection method of the heat collected by the underground heat exchanger and the implementation form of the same detection device in the present invention, it will be described with reference to FIG. 1 . This device uses water as the heat medium 2, and is equipped with a supply tank 1, an intermediate tank 14, an underground heat exchanger 4, a circulation path 7, a circulation pump 8, a valve 9, a flow meter 10, a first heat medium thermometer 11, a second Thermal medium thermometer 12 and geothermal thermometer 13. Of course, the heat medium 2 is not limited to water, for example, an antifreeze liquid may also be used.

[0010] The supply tank 1 needs to be filled with ice cubes 3 in order to keep the water heat medium 2 at 2° C. to 4° C., and is also provided with an intermediate tank 14 communicating with it and also filled with ice cubes. The underground heat exchanger 4 is a concentric double-tube type consisting of an outer cylinder 5 with a closed ...

Abstract

PROBLEM TO BE SOLVED: To suppress fluctuation of resistance value due to variance of resistor shape or of resistor element when integrally sintering an insulation substrate composed of glass ceramic. and a resistor. SOLUTION: A wiring board is provided with an insulation substrate 3 comprising a glass ceramic sintered body, a resistor 1 integrally sintered with the insulation substrate 3 inside of and / or on a surface of the substrate 3, and a wiring conductor 2 whose ends are connected overlapping with the upper portions of both ends of the resistor 1. The resistor 1 in the wiring board contains 40-70 mass% tin oxide and 30-60 mass% platinum. Resistance value of the resistor 1 is stabilized by controlling reaction / diffusion phenomenon with glass ceramics with a resistor composition material, and by stabilizing the resistor shape.

Description

technical field [0001] The present invention relates to the use of the heat collected by the ground heat exchanger for snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding when utilizing geothermal heat. A method and device for measuring the circulating volume of heat medium, the temperature of the heat medium and the temperature of geothermal heat. Background technique [0002] So far, although it has been considered to use underground water (warm water) for snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding, etc., it has not been actively implemented in practice because a large amount of water is extracted. Groundwater will cause problems such as subsidence of the foundation. [0003] In recent years, a method of using geothermal energy to replace groundwater has been proposed, that is, an underground heat exchanger is buried in the ground, and heat ...
