Problems solved by technology

[0002] In the past, groundwater (warm water) was used to consider the use of snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding. However, drawing a large amount of groundwater will cause subsidence of the foundation, and it is hardly used now. implemented by a technique

Embodiment Construction

[0008] Affect the embodiment of the geothermal exchange device of the present invention, such as figure 1 and shown in Figure 2. This device is to insert the inner tube 1b concentrically into the outer tube 1a with the closed bottom, and the gap passage 1c formed between the outer tube 1a and the inner tube 1b, and the concentric double tube heat exchanger 1 formed in this way is vertically The ground is buried in the ground, and then the heat medium (antifreeze) is fed from the upper part of the inner cylinder. When the heat medium reaches the bottom of the pipe, it turns over and enters the gap passage 1c, and collects geothermal heat during the ascent process, and then transfers the collected geothermal heat It is sent to the heat release pipe 2 laid under the road surface through the circulation channel 3, and is released at the heat release pipe 2 to melt snow accumulation.

[0009] The device constituted in this way is further said that on the circulation passage 3, th...

Abstract

PROBLEM TO BE SOLVED: To provide a geothermal heat exchange apparatus capable of efficiently collecting geothermal power. SOLUTION: A heat exchanger 1 for collecting geothermal power by heat exchange is vertically laid underground. The geothermal power collected by the heat exchanger 1 is transferred to a radiating pipe 2 through a circulating path 3 and is emitted from the radiating pipe 2 for snow melting or the like. In this apparatus, the circulating path 3 is provided with two heating medium circulating pumps 4 one of which is a backup, an expansion tank 5 for absorbing a volume change of the heating medium, and a pressure detector 6 for detecting a pressure lower limit due to leakage of the heating medium or the like and stopping the circulating pumps 4.

Description

technical field [0001] The present invention is a geothermal heat exchange device that can utilize geothermal energy in snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding. Background technique [0002] In the past, groundwater (warm water) was used to consider the use of snow melting, air conditioning, hot water supply, warm water swimming pool, plant cultivation, or animal breeding. However, drawing a large amount of groundwater will cause subsidence of the foundation, and it is hardly used now. implemented by a technique. [0003] In recent years, it has been considered to bury a heat exchanger for collecting geothermal heat in the ground, in which the heat exchange with the geothermal heat is carried out through the transmission of the heat medium, and the heat energy collected in this way is used for snow melting and other operations. device. Contents of the invention [0004] Yet this device in the past ...
