  The thermal heat storage tank 113 is provided directly below the heat collecting plate 111 and stores the thermal energy collected by the heat collecting plate 111. Although the fluid (antifreeze) is stored in the thermal heat storage tank 113, a solid material such as soil can be stored instead.

  The underground heat pile 114 is composed of a plurality of U-shaped pipes, and is buried vertically in the ground, and in the summer, the underground thermal energy is collected by a fluid (antifreeze) flowing inside.

  The controller 116 supplies the thermal energy collected by the heat collecting plate 111 and the underground heat pile 114 to the heat exhaust plate 115. In the winter, the heat exhaust plate 115 is supplied by a command from the controller 116. The thermal energy is supplied from the thermal energy, and the pavement layer 101 is melted with the thermal energy.

In winter, the thermal energy is supplied to the thermal supply pipe 115a of the exhaust heat plate 115 provided immediately below the runway in accordance with a command from the controller 116. Thereby, since the thermal energy is released from the exhaust heat plate 115, snow melting of the pavement layer 101 can be performed effectively.

In addition, the heat collecting plate 111 in this modified example is set to the same size as the pavement layer 101. Therefore, the thermal energy can be collected effectively in a wide range, and a large amount of thermal energy can be stored in the thermal storage tank 113. Thereby, it is possible to perform snow melting more effectively in winter by abundant thermal energy.

FIGS. 15 to 17 show a fifth modification of the solar thermal geothermal heat storage and supply facility 110 according to the present invention.

A base layer 119 made of concrete or asphalt is provided directly below the heat collecting plate 111. By providing this base layer 119, it is possible to prevent the thermal energy and cold energy collected by the heat collecting plate 111 from being released into the ground.

  The heat collecting plate 111 is laid horizontally near the ground surface in the ground, and has a heat collecting pipe 18 in which fluid (antifreeze) flows inside, collecting the thermal energy of sunlight in the summer, and in the winter In this case, the energy of cold energy is collected.

  The thermal heat storage tank 113 is provided directly under the building 102, stores the thermal energy supplied from the heat collecting plate 111 in the summer, and supplies the thermal energy to the heating of the building 102 in the winter.

  The cold heat storage tank 117 is also provided immediately below the building 102 and stores cold energy supplied from the heat collecting plate 111 in winter. In summer, cold energy is supplied to the heating of the building 102.

  The underground heat pile 114 is composed of a plurality of U-shaped pipes and is buried vertically in the ground. In the summer, the underground thermal energy is collected by a fluid (antifreeze) flowing inside. It is supplied to the thermal heat storage tank 113. In winter, the cold energy in the ground is collected and supplied to the cold heat storage tank 117.

In the summer, the solar geothermal heat storage and supply equipment 110 according to this modified example collects the thermal energy of sunlight with the heat collecting plate 111 and collects the thermal energy of the ground with the underground heat pile 114, and uses them. Store in the thermal storage tank 113. In winter, the stored thermal energy is used for heating the building 102. Therefore, the building 102 can be effectively heated.

  In winter, the thermal energy is collected by the heat collecting plate 111 and the underground thermal energy is collected by the underground heat pile 114 and stored in the cold heat storage tank 117. In the summer, the cold energy is used for cooling the building 102. Therefore, the building 102 can be effectively cooled.

  Moreover, since the thermal storage tank 113 and the cold storage tank 117 are respectively provided directly under the building 102, for example, the second floor portion is air-cooled and heated via the cooling / heating device 103, and the first floor section is replaced with the thermal storage tank 113 and Floor heating and floor cooling can be performed directly from the cold heat storage tank 117 through the floor 102a of the building 102. Thereby, more effective cooling and heating can be performed.

FIG. 18 shows a second embodiment of the solar geothermal heat storage and supply facility according to the present invention. This is the structure of the first embodiment in which intermediate soil layers 86 and 87 having a thickness of 20 to 30 cm are provided between the heat exchange pipe groups 81 and 91 and the foamed polystyrene plates 83 and 93 for heat insulation. is there. By doing so, heat can be stored not only by the soil layers 85 and 95 but also by the intermediate soil layers 86 and 87, so that the heat storage effect can be further enhanced.

  Soil is a container of heat with a sufficiently large capacity, but in the natural state, large inflow and outflow of heat particularly occur from its surface. Therefore, it is a feature of the present invention that the ground is used as a large heat storage tank by covering the surface with a heat insulating material.

In above-mentioned 2nd embodiment, in order to take out and store heat from this thermal storage tank, the heat exchange pipe is embed | buried under 20-30 cm of a heat insulating material. That is, intermediate soil layers 86 and 87 having a thickness of 20 to 30 cm are formed between the foamed polystyrene plates 83 and 93 and the soil layers 85 and 95 for heat insulation.

  And pipes are buried in the road paving slab as a heat supply source, thereby collecting solar radiation from the sun and cold in the winter, and connecting this to the underground heat exchange pipes It stores the exhaust heat that accompanies cooling and heating of the building in this underground heat storage tank. When this means is used for road snow melting, the heat release plate used for snow melting can be used as it is as the heat collecting plate described below, and the heat collecting pipe at the time of snow melting underground becomes a heat storage pipe to the underground in summer.

  The present invention uses a geological layer near the surface of the underground (up to a depth of about 10 m) as a heat storage tank, unlike the means of using underground heat or heat stored in the ground using groundwater. The heat (or exhaust heat associated with cooling) is stored in this heat storage tank, and it is taken out in winter and used for melting snow on roads and parking lots or heating buildings. Conversely, the cold stored in the winter is taken out in the summer to cool the roads and parking lots or cool the building, thereby alleviating the heat island phenomenon.

  In other words, the heat discarded for cooling in the summer is stored in the ground, taken out in the winter, and the heat storage tank cooled by heat collection in the winter is effectively used for cooling in the summer. It balances the heat balance and minimizes the energy used.

The following effects are further recognized in the present invention.
(1) Since only the heat collection / radiation pipe and the heat insulating material are buried near the surface of the earth, the structure is simple and the construction cost is low compared with other methods (embedding deep underground).
(2) By effectively using energy from the sun received by roads, parking lots, etc., it is possible to reduce energy consumption from fossil fuels.
(3) The heat island phenomenon can be mitigated, and this system is friendly to the global environment along with energy saving.
(4) As a result of building cooling and heating, the heat energy released and absorbed is stored in the ground and reused throughout the year, so that energy consumption in cooling and heating can be reduced.

In addition, the present invention has the following utilization method and its accompanying effects.
(1) Road maintenance costs can be reduced by melting snow on winter roads (including runways) and preventing overheating of summer roads.
(2) Annual energy consumption can be reduced by using it as a heat source for air conditioning of buildings.
(3) It helps to mitigate urban heat island phenomenon by storing road heat in summer and exhaust heat from buildings underground and not releasing it to the outside.
