Claims

[Scope of utility model registration request]

(1) An underground heat collection device that includes a space formed underground and a heat pumping device that pumps up underground heat from this space.

(2) The heat pumping device is a heat pump in which an expansion valve and an evaporator are housed in the space, and a plurality of heat collecting parts each consisting of the expansion valve and the heat generator are located at different underground depths, and In addition to being connected in parallel with each other, each heat collecting section installs an on-off valve on the heat medium supply pipe that sends the heat medium, and the temperature in the space at each depth underground is detected by a temperature sensor and the on-off valve is activated. An underground heat extraction device according to claim (1) of the utility model registration claim, which is provided with a control device for opening and closing.

(3) The space contains a heat storage material and forms an insulating air layer around it, and the heat pumping device is a ventilation duct equipped with a fan, and the heat storage material is equipped with a solar heat collector. The underground heat collection device according to claim 1, which stores collected heat and radiates heat from the heat storage material through the ventilation duct.
