Document Type and Number:
Japanese Patent JP7219857
Kind Code:
B2
Abstract:
To solve the problem in which a conventional underground heat utilization equipment installation work had less versatility and had not been spread well due to a high cost for transportation and assembly by a large-sized machine and a treatment of drilled earth in construction and its heat efficiency during the winter is low and the energy saving effect is low as well, thus the underground heat utilization technology had not been spread and therefore it cannot contribute to carbon dioxide reduction.SOLUTION: Underground heat which is energy renewable a low cost and high efficiency by equipment for concentric shaft multilayer structure underground heat exchanger installation, and solar heat and atmosphere heat can be exchanged by equipment for the concentric shaft multilayer structure underground heat exchanger installation buried underground, thus it enables cooling in free cooling manner by a circulation cold of heating medium liquid during summer. During winter, the underground temperature can be recovered by circulation heated water of solar heat underground during daytime, the underground temperature is lowered when an underground heat pump is utilized at night, circulation liquid of a solar heat collection circuit by solar heat during daytime brings a warming heat storage effect and is effective for utilization of underground heat in the morning and at night, thus it enables a peak cut of consumption power during winter and the power saving effect is significantly improved.SELECTED DRAWING: Figure 1
