As a result, the heat medium 2 in the supply tank 1 kept at 2 ° C. to 4 ° C. is supplied to the underground heat exchanger 4 through the outward path 7 a via the intermediate tank 14. At this time, the circulation amount of the heat medium 2 is set to a predetermined value by the valve 9 and the flow meter 10.

Then, the temperature of the heat medium 2 before the underground heat extraction (temperature of the inlet side 4a)
And the temperature after sampling (the temperature on the outlet side 4b) are measured after a certain period of time. Based on the respective measured values thus obtained and the circulation amount of the heating medium 2, it is possible to detect the amount of underground heat that can be collected at the predetermined place.

模を設定することができる。For example, when a certain amount of the heat medium 2 is circulated for a certain period of time, the heat exchange causes the temperature of the heat medium 2 on the outlet side 4b to rise, while the temperature of the underground heat decreases. The temperature of the heat medium 2 on the outlet side 4b (the temperature measured by the second heat medium thermometer 12) is higher than the temperature on the inlet side 4a (the temperature measured by the first heat medium thermometer 11), and If the temperature of heat (the temperature measured by the underground heat thermometer 13) maintains a constant state as it is, it means that that much underground heat can be stably collected at that location. The number and scale of the underground heat exchangers 4 to be buried can be set based on that.

に行うことができる。On the contrary, for example, when the temperature of the outlet side 4b of the heat medium 2 decreases to the same level as the temperature of the inlet side 4a, or the temperature of the underground heat continues to decrease, that much is found at that place. Since it means that there is no underground heat, the valve 9 is throttled to reduce the circulation amount of the heating medium 2 until the temperature becomes stable. Then, when the temperatures become stable, the number of the underground heat exchangers 4 and the like are set based on the stable temperature. In this way, by using this sampling heat quantity detection method and the apparatus thereof, it is possible to easily make a concrete underground heat utilization plan.
