PURPOSE:To permit to utilize air, whose heat is exchanged with the heat of groundwater, for snow melting and room heating in winter and room cooling or the like in the summer by a method wherein the air is sent into a well pipe, buried deep into ground, and the heat thereof is exchanged at the deep position of the well pipe, then, the air is taken out above the ground. CONSTITUTION:The well pipe 1 is buried deep into ground, an air sending pipe 2, sending air above the ground, is laid in the well pipe, the end of the air sending pipe 2 is connected to a forced air sending device 3, provided above the ground, the upper opening of the well pipe 1 is closed by a lid 4 and a delivery pipe 5, sending air which has already finished heat exchange into a desired place, is connected to the lid 4. When the air above the ground is sent to the deep part of the well pipe 1 by the forced air sending device 3 through the air sending pipe 2 and is discharged, the heat of the discharged air is exchanged with the heat of ground water in the well pipe 1 or the vein of water, then the air whose heat is exchanged already, is taken out above the ground and is utilized for the source of room cooling or heating, therefore, subsidence of ground as well as the pollution of groundwater may be prevented surely. |
