本実施例では、閉塞空間４０を、温調空間２０の長手方向一端側に接続するように設けている。 <5> Blocked space (Fig. 1)
The closed space 40 is a space partitioned so as to surround the vicinity of the air conditioner 30.
The closed space 40 is not configured to communicate with all of the work space in the vinyl house A, but is configured to communicate with the temperature control space 20 described above.
By sending the warm and cold air output from the air conditioner 30 in the closed space 40 to the temperature control space 20, the circumference of the cultivation bed 10 is adjusted to a predetermined temperature.
The "blocking" in the closed space 40 in the present invention is not intended to be a completely closed state, but is not intended to be a completely closed state, but is a temperature control space communicating with the entrance / exit of the worker, the intake / exhaust port required for the air conditioner 30, and the closed space 40. It is intended to allow the leakage of warm and cold air from the gaps and the like that are slightly formed during the construction of the 20 and to substantially block the air.

＜７＞使用イメージ（図２，３）
次に、図２，図３を参照しながら、本発明に係る温度調整構造の使用イメージについて説明する。 <7> Usage image (Figs. 2 and 3)
Next, an image of using the temperature control structure according to the present invention will be described with reference to FIGS. 2 and 3.

＜７．１＞使用状態（図３）
送風機５０の稼働によって温調空間２０内における栽培ベッド１０よりも下方の領域は、送風機５０から閉塞空間４０側へと空気が流れる。
この空気の流れに伴い、温調空間２０の長手方向他端側では、栽培ベッド１０の上部側から下部側へと折り返すように空気が流れる。
上記の流れによって、温調空間２０の上部側では、温調空間２０の長手方向一端側から他端側へと空気の流れができ、閉塞空間４０に出力された暖冷気は、温調空間２０の上部側の開口部へと流れる。また、温調空間２０の下部側は、送風機５０による空気の流れでもって、暖冷気の流れが逆流することを防止している。 <7.1> Usage status (Fig. 3)
Due to the operation of the blower 50, air flows from the blower 50 to the closed space 40 side in the region below the cultivation bed 10 in the temperature control space 20.
Along with this air flow, on the other end side of the temperature control space 20 in the longitudinal direction, air flows so as to fold back from the upper side to the lower side of the cultivation bed 10.
Due to the above flow, air flows from one end side in the longitudinal direction to the other end side of the temperature control space 20 on the upper side of the temperature control space 20, and the warm / cold air output to the closed space 40 is the temperature control space 20. It flows to the opening on the upper side of. Further, the lower side of the temperature control space 20 prevents the flow of warm and cold air from flowing backward due to the flow of air by the blower 50.

＜７．２＞非使用時（図２）
温調空間２０内の温度が過度に上昇または低下している場合や、夜間など温度調整の必要性に乏しい場合には、図２で示したように、シート２１の側部を下から捲りロール状に巻き取るなどして開放しておけば、温調空間２０とビニールハウスＡ内のその余の空間との間を連通させて換気することができる。 <7.2> When not in use (Fig. 2)
When the temperature in the temperature control space 20 is excessively increased or decreased, or when there is little need for temperature adjustment such as at night, as shown in FIG. 2, the side portion of the sheet 21 is rolled up from below and rolled. If it is opened by winding it up in a shape, the temperature control space 20 and the remaining space in the vinyl house A can be communicated with each other for ventilation.

［ＣＯ２供給機の追加］（図４）
本発明の第２実施例について、図４を参照しながら説明する。
本発明では、温調空間２０にＣＯ２ガスを送り込む、ＣＯ２供給機６０を設けてもよい。なお、図４では、ＣＯ２供給機６０を空調機３０と同一空間に設置しているが、本発明では上記の設置例に限定するものではない。
ＣＯ２供給機６０は、炭酸ガス発生機や光合成促進機とも呼ばれる公知の装置を用いることができる。
また、本発明において空調機３０とＣＯ２供給機６０とは別体の装置であることを限定するものではなく、一体化した装置を用いても良い。
また、空調機３０として用いるボイラーの燃焼で排出された排気ガスに含まれるＣＯ２を流用してもよい。
このＣＯ２供給機６０からＣＯ２ガスを温調空間２０内に送り込むことで、温調空間２０内の二酸化炭素濃度を高めることができる。
また、温調空間２０内は、ビニールハウスＡ内のその余の空間から区画されているため、作業従事者が歩き回るその他の空間内の二酸化炭素濃度が高くなりにくく、息苦しさ、倦怠感、頭痛などの人体に対する影響も発生しない。
その結果、作業従事者の人体に悪影響を生じさせることなく、温調空間２０内の二酸化炭素濃度を光合成の促進が期待できる望ましい値にまで高めることができ、栽培対象Ｂの成長を促進させることができる。 [ Addition of CO 2 supply machine] (Fig. 4)
A second embodiment of the present invention will be described with reference to FIG.
In the present invention, a CO 2 supply machine 60 that sends CO 2 gas to the temperature control space 20 may be provided. Although the CO 2 supply device 60 is installed in the same space as the air conditioner 30 in FIG. 4, the present invention is not limited to the above installation example.
As the CO 2 supply machine 60, a known device also called a carbon dioxide gas generator or a photosynthesis accelerator can be used.
Further, in the present invention, the air conditioner 30 and the CO 2 supply device 60 are not limited to be separate devices, and an integrated device may be used.
Further, CO 2 contained in the exhaust gas discharged by the combustion of the boiler used as the air conditioner 30 may be diverted.
By sending CO 2 gas from the CO 2 supply machine 60 into the temperature control space 20, the carbon dioxide concentration in the temperature control space 20 can be increased.
Further, since the temperature control space 20 is partitioned from the remaining space in the vinyl house A, the carbon dioxide concentration in the other spaces where the worker walks around is unlikely to increase, resulting in suffocation, fatigue, and headache. There is no effect on the human body.
As a result, the carbon dioxide concentration in the temperature control space 20 can be increased to a desirable value that can be expected to promote photosynthesis without causing an adverse effect on the human body of the worker, and the growth of the cultivation target B can be promoted. Can be done.

温調空間２０は畝Ｃを跨ぐように配置したアーチ状の支柱材と、当該支柱材を骨組として畝の近傍周囲を覆うように敷設したシートでもって構成することができる。
温調空間２０の長手方向一端側は、空調機３０を設置している閉塞空間４０に接続している。
また、温調空間２０の長手方向他端側には、換気扇からなる送風機５０を設けつつ、ビニールハウスＡ内に別途設けたダクト７０を接続している。
各温調空間２０に接続したダクト７０の出口は閉塞空間４０へと繋がり、温調空間２０を通った暖冷気は、送風機５０によってダクトへと送られ、閉塞空間４０へと循環する。
また、図５に図示しないが、実施例２で説明した暖冷気の流路の途上に、ＣＯ２供給機を追加してもよい。
当該構成によっても、畝の周りに設けた温調空間自体がビニールハウス内に設置された局所的なビニールハウスとして機能し、栽培対象の育成促進のための温度調整コストを削減することができる。 [Application example in soil cultivation] (Fig. 5)
A third embodiment of the present invention will be described with reference to FIG.
The temperature control structure according to the present invention can also be applied to so-called soil cultivation, that is, when the cultivation target is planted on the ground in a vinyl house.
In the schematic plan view shown in FIG. 5, a plurality of linearly extending ridges C are arranged in one vinyl house A, and a temperature control space 20 is formed for each of the ridges C.
The temperature control space 20 can be configured by an arch-shaped strut material arranged so as to straddle the ridge C and a sheet laid so as to cover the vicinity of the ridge with the strut material as a frame.
One end side of the temperature control space 20 in the longitudinal direction is connected to the closed space 40 in which the air conditioner 30 is installed.
Further, on the other end side of the temperature control space 20 in the longitudinal direction, a blower 50 made of a ventilation fan is provided, and a duct 70 separately provided in the vinyl house A is connected.
The outlet of the duct 70 connected to each temperature control space 20 is connected to the closed space 40, and the warm / cold air passing through the temperature control space 20 is sent to the duct by the blower 50 and circulates to the closed space 40.
Further, although not shown in FIG. 5, a CO 2 supply device may be added in the middle of the hot / cold air flow path described in the second embodiment.
Even with this configuration, the temperature control space itself provided around the ridges functions as a local greenhouse installed in the greenhouse, and the temperature control cost for promoting the growth of the cultivation target can be reduced.

［閉塞空間の省略］（図示せず）
本発明では、閉塞空間４０を設けない構成とすることもできる（図示せず）。
例えば、空調機３０がダクト出力である場合、このダクトと温調空間２０とを接続させれば、空調機３０からの暖冷気を直接温調空間２０に送り込むこともできる。 [Omission of closed space] (not shown)
In the present invention, the blockage space 40 may not be provided (not shown).
For example, when the air conditioner 30 has a duct output, if the duct and the temperature control space 20 are connected, the warm / cold air from the air conditioner 30 can be directly sent to the temperature control space 20.
