内余剰熱と温室外の太陽熱または廃熱を地層内に蓄えて
夜間の暖房に利用する地中蓄熱温室に関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to an underground heat storage greenhouse that stores internal surplus heat and solar heat or waste heat outside the greenhouse in a stratum and uses it for nighttime heating.
従来の地中蓄熱温室としては，昼間の温室内余剰熱を地
中に蓄える方式を［采用したもの（内部集熱型地中蓄熱
温室）と温室外の太陽熱を地中に蓄える方式を採用した
もの（外部集熱型地中蓄熱温室）がある。Conventional underground heat storage greenhouses have adopted a method that stores the surplus heat inside the greenhouse during the day underground (internal heat collecting type underground heat storage greenhouse), and a method that stores the solar heat outside the greenhouse underground. (external heat collection type underground heat storage greenhouse).
しかし、いずれもそれらの蓄熱量だけでは，夜間の温室
暖房の必要量を総て賄うことができず。However, in both cases, the amount of heat stored cannot cover the entire greenhouse heating requirement at night.
補助暖房設備が必要であり７そのエネルギー源は。Auxiliary heating equipment is required, and what is its energy source?
化石燃料に依存している。dependent on fossil fuels.
その原因は，内部集熱型地中蓄熱温室においては，蓄熱
方式が一日単位であるため，雨天，曇天日には，蓄熱量
が減り，夜間暖房惜が不足する。The reason for this is that internal heat collection type underground heat storage greenhouses store heat on a daily basis, so on rainy or cloudy days, the amount of heat stored decreases, resulting in a lack of nighttime heating.
また、外部集熱型地中蓄熱温室は，蓄熱方式が。In addition, external heat collection type underground heat storage greenhouses use a heat storage method.
１週間〜月間単位であるものの，その蓄熱量だけで夜間
暖房を賄う場合，太陽熱集熱器の面積は。If the amount of stored heat is enough to provide nighttime heating for a period of one week to a month, what is the area of the solar collector?
温室面積のＡ−ｌイが必要とされており、その設置面積
が犬であることと、建設費が高くなることより、集熱器
の面積を少なくせざるを得す、補助燃料を［吏用してい
る。Since greenhouse area A-1 is required, the installation area is small and the construction cost is high, so it is necessary to reduce the area of the heat collector, and it is necessary to use auxiliary fuel. I am using it.
本発明の目的は、前記従来技術の欠点を解消し。The object of the present invention is to overcome the drawbacks of the prior art.
省エネルギー効果を増加し、しかも設置面積や建設費を
少なくすることにある。The aim is to increase the energy saving effect and reduce the installation area and construction cost.

方式の差異を考慮してなされたも弓ゲあり２本発明の！
特徴は温室内外の地中に夫々。The present invention was made in consideration of the difference in the underground heat transfer method between an internal heat collection type underground heat storage section (underground heat storage section outside a greenhouse) and an external heat collection type underground heat storage section (underground heat storage section inside a greenhouse). Game and 2 inventions!
The characteristics are underground, inside and outside the greenhouse.

するように構成した点にある。即ち、内部集熱型地中蓄
熱部は伝熱器と周囲地層間の熱の授受であり、昼間は。Heat transfer devices are installed, and these heat transfer devices form an underground heat storage area together with the surrounding soil, and the air inside the greenhouse is supplied to the heat transfer vessel forming the underground heat storage area outside the greenhouse. A fluid heated by solar heat or waste heat is circulated through the heat transfer device forming the heat storage section, and the heat transfer device forming the underground heat storage section in the greenhouse is installed at a depth of 04 to 07 m from the ground surface. The point is that it is configured to do so. In other words, the internal heat collection type underground heat storage section transfers heat between the heat transfer device and the surrounding strata during the day.
伝熱器より地層へ、夜間は、地層より伝熱器への熱の移
動であり、その熱流の地中に及ぼす範囲は。At night, heat transfers from the heat transfer device to the geological formation, and from the formation to the heat transfer device, and the extent to which this heat flow affects the underground.

となるので０４゛へ以下の深さで適宜、設置位置を決め
ればよい。It is said to be 10 to 5 cm from the surface of the heat transfer device. Sword 2
It is said that the range that temperature changes on the earth's surface in diurnal (-day) units affect underground is 25 cn1 to 30 cntn below the earth's surface. Therefore, if the heat transfer device is placed at a depth of 0.4 m or more underground, even if the underground heat storage section is installed outside the greenhouse, the heat will not be dissipated to the ground surface in layers and will not be affected by the ground surface temperature. If installed deeper than necessary, the construction cost will increase and groundwater countermeasures will be required, so the installation position should be determined appropriately at a depth below 04゛.

熱器は、必ず温室内地表に設置しなければならない。ま
た、伝熱器の地表からの深さは、大であれば犬である程
伝熱抵抗が増大し。On the other hand, in an external heat collection type underground heat storage unit, the heat transfer device must be installed on the surface of the greenhouse in order to heat the greenhouse using the heat flow flowing from the heat transfer device to the surface of the earth via the strata. Also, the greater the depth of the heat transfer device from the ground, the greater the heat transfer resistance.
地表への熱流束が減少し、暖房効果を減少させる。The heat flux to the ground is reduced, reducing the heating effect.
また、浅過ぎても、地中蓄熱量が減少し、雨天。Also, if it is too shallow, the amount of heat stored underground will decrease, resulting in rainy weather.
曇日には、暖房効果が減少する。これらのことを考慮し
、外部集熱型地中蓄熱部を形成する伝熱器を温室内地下
０４〜０．”７ｍに設けるものである。On cloudy days, the heating effect is reduced. Taking these things into consideration, a heat transfer device forming an external heat collecting type underground heat storage section was installed underground in the greenhouse from 04 to 0. ``It is installed at a height of 7 m.

This will be explained with reference to FIG. FIG. 1 is a side view, and FIG. 2 is a plan view. A heat transfer device 2 of an external heat collection type underground heat storage section is buried 0.5 m underground of the greenhouse body 1, and hot water heated by a solar heat collector 3 flows into the heat transfer device. This heats the underground and forms an underground heat storage area. The hot water circulation system includes a circulation tank4. A pump 5 is provided. In addition, an internal heat collection type underground heat storage-concave ρ heat transfer device 6 is buried 0.5771 m below the ground of the solar heat collector 3, and the air inside the greenhouse body l flows into the heat transfer device, and the geological layer The exchange of heat was accomplished.

を利用する場合には終日、運転される場合もある。It operates continuously, regardless of night time, and the underground heat storage section (external cold heat type) inside the greenhouse is operated only during the day. Do not operate at night as heat is dissipated from the heat collector. The indoor heat storage section mainly releases heat into the room gradually on a weekly basis through the strata. Therefore, during the night, heat is supplied from both heat storage sections. On the other hand, the outdoor heat storage section exchanges heat with the greenhouse on a daily (layer) basis using indoor air as a heat medium. In this embodiment, the underground heat storage section in the greenhouse uses solar heat, so it is operated only during the day, but if waste heat or the like is used, it may be operated all day.
