A heat transfer medium liquid circulation flow channel having a first heat exchange unit exchanging heat to a second heat exchange unit is provided, and a fixed amount of first heat transfer medium liquid circulates therein. A feed pipe couples heat source holding second heat transfer medium liquid having temperature difference from the first medium liquid to the heat transfer medium liquid circulation flow channel. The feed pipe is coupled to an inlet end side of the first heat exchange unit and a discharge pipe is coupled to an outlet end side thereof. A necessary amount of second medium liquid is supplied to the inlet end side via the feed pipe so that a detected temperature of the first medium liquid in the outlet end maintains required set temperature. The same amount of the first medium liquid as the supplied second medium liquid is discharged out of the discharge pipe.
[Problem] To provide a heat exchange device with which it is possible to effectively utilize the thermal energy of a heat source. [Solution] The present invention is provided with a heat transfer medium circulation channel 7 having a first heat exchange unit 6 for exchanging heat with a second heat exchange unit 5. A fixed amount of a first heat transfer medium 9 circulates in the heat transfer medium circulation channel 7. A heat source 11, which holds a second heat transfer medium 10 having a temperature difference with respect to the temperature of the first heat transfer medium 9, and the heat transfer medium circulation channel 7 are coupled by a feed pipe 12. The feed pipe 12 is connected to the side of the first heat exchange unit 6 on which an inlet end 13 is present, and a discharge pipe 19 is connected to the side of the first heat exchange unit 6 on which an outlet end 16 is present. A necessary amount of the second heat transfer medium 10 is fed through the feed pipe 12 to the side on which the inlet end 13 is present so that the detected temperature of the first heat transfer medium 9 at the outlet end 16 is kept at a required set temperature. The same amount of the first heat transfer medium 9 as that of the fed second heat transfer medium 10 is discharged from the discharge pipe 19.

An underground heat exchanger has a bottomed tubular flexible bag body accommodated in an accommodation hole portion in the ground, and an outer tube accommodated in the accommodation hole portion, vertically extending along an outer surface portion of the bag body and communicating in its lower end with a lower end of the bag body. The outer surface portion of the hardening resin bag body can cover an inner wall portion of the accommodation hole portion in a closely contact state with the bag body being inflated. The bag body is hardened in the covering state, a lining tubular body formed by the hardening can form a liquid storage tank for storing a heat medium liquid in its internal space, and the outer tube is pinched between the outer surface portion of the bag body and the inner wall portion.

METHOD FOR CONTROLLING HEAT EXCHANGE DEVICE, HEAT EXCHANGE DEVICE, AND WATER-COOLED HEAT PUMP DEVICE
[Problem] To provide a heat exchange device with which it is possible to effectively utilize thermal energy held by geothermal heat. [Solution] The present invention is provided with a heat transfer medium circulation channel 7 having a first heat exchanger 6 for exchanging heat with a second heat exchanger 5. A given quantity of a first heat transfer medium 9 circulates in the heat transfer medium circulation channel 7. A heat source 11, which holds a second heat transfer medium 10 having a temperature difference with respect to the temperature of the first heat transfer medium 9, and the heat transfer medium circulation channel 7 are connected by a feed pipe 12. The feed pipe 12 is connected to the side on which an inlet end 13 of the first heat exchanger 6 is present, and a discharge pipe 19 is connected to the side on which an outlet end 16 of the first heat exchanger 6 is present. A necessary amount of the second heat transfer medium 10 is fed through the feed pipe 12 to the side on which the inlet end 13 is present so that the detected temperature of the first heat transfer medium 9 at the outlet end 16 is kept at a required set temperature. The same amount of the first heat transfer medium 9 as that of the fed second heat transfer medium 10 is discharged from the discharge pipe 19.
[Problem] To provide an underground heat exchanger capable of ensuring an improvement in heat efficiency. [Solution] The present invention is provided with: a flexible bottomed cylindrical bag body 5 which is housed in a housing hole 3 vertically provided in a ground 2 and extends vertically; and an outer pipe 10 which is housed in the housing hole 3 and extends vertically along the outer surface 6 of the bag body 5, and which has a lower end 7 communicating with the lower end of the bag body 5. When the bag body 5 comprising a curable resin is in an expanded state, the outer surface 6 of the bag body 5 covers the inner wall 11 of the housing hole 3 in close contact therewith. The bag body 5 is cured in such a covering state. The lining cylindrical body 15 formed by curing forms a liquid storage tank 19 for storing heat transfer liquid 17. The outer pipe 10 is held between the outer surface 6 of the bag body 5 and the inner wall 11.
