いわゆる太陽熱暖房方法に関している。[Detailed Description of the Invention] <Technical Field> The present invention relates to a method for heating a greenhouse, in which a heat medium is circulated between a heat collector and a heat storage tank that receive solar heat during the day, and the solar heat is stored in the heat storage tank. At night, the heat medium is circulated from the heat storage tank through the heat exchange pipes installed inside the greenhouse to supply heat to the greenhouse.
It concerns the so-called solar heating method.

During the day when the sun's rays are strong, a large amount of solar heat must be collected using a heat collector and stored in a heat storage tank.

ではなかつた。 However, since the heat collection efficiency of the heat collector is constant,
The only way to increase the amount of solar heat collected is to increase the capacity of the collector or increase the number of collectors installed, which poses the problem of high equipment costs. Moreover, since solar heat varies depending on the season and climate,
It was wasteful and uneconomical to set the capacity of the heat collector according to the conditions that required the largest amount of heat.

気冷却を行う必要がある場合もあつた。 In addition, when examining the temperature changes inside a typical greenhouse, it is found that during the night, such as in late autumn, the temperature drops to a low temperature that requires heating, but during the daytime, the temperature rises to a considerably high temperature, and there is no need for heating at all. In some cases, the temperature inside the greenhouse rose so high that it was necessary to open the plastic sheet covering the greenhouse to ventilate and cool the greenhouse.

This material, which was previously only used in greenhouses, can also be used as a heat collecting member that absorbs heat inside the greenhouse, and its heat collecting action stores the heat inside the greenhouse in a heat storage tank, improving heat storage efficiency and amount. In addition, during the heat collection process, the greenhouse can be cooled by the heat collection action of the heat exchange pipes, so it is possible to prevent the temperature of the greenhouse from becoming too high.

A large amount of thermal energy is supplied from the sun to the heat collector 1, and at the same time the greenhouse H that makes up the greenhouse
Solar heat is also supplied to the inside of the vinyl tunnel T.
そして、集熱器１内の温度が一定温度（例えば

制御盤２で制御しているポンプ３０を作動させ、
蓄熱槽３内の熱媒体を吐出配管31へと送り出し、
集熱過程を実行する。 Then, the temperature inside the heat collector 1 is a constant temperature (for example,
When the temperature exceeds 35℃, the temperature sensor 10 detects the temperature.

蓄熱槽３と集熱器１との間を循環すると同時に、
蓄熱槽３と熱交換パイプ４との間でも循環する。 That is, by opening the two-way joint 32 provided on the discharge pipe 31 of the pump 30 so that it communicates with both the heat collector 1 and the heat exchange pipe 4, As shown in FIG. 3, the heat medium circulates between the heat storage tank 3 and the heat collector 1, and at the same time,

In addition, the heat medium circulating on the heat exchange pipe 4 side also collects the thermal energy supplied inside the vinyl tunnel T due to strong sunlight during the day and stores it in the heat storage tank 3. It also acts as a cooling agent by absorbing excess solar heat.

With the control valve 33 connected to the heat collector 1 side closed, the pump 30 is operated to carry out the heat dissipation process. That is, as shown in FIG. 4, the heat medium that has sufficiently accumulated heat during the day and reached a high temperature circulates through the heat exchange pipe 4 and radiates heat within the vinyl tunnel T, thereby increasing the temperature inside the vinyl tunnel T. Keeping the crop P warm,
This will prevent the temperature from dropping at night. In addition, if the pump 30 is operated intermittently by a timer installed in the operation panel 2, the thermal energy stored in the heat medium can be effectively used, and the crops P can be heated for a long period of time. A suitable growth temperature can be maintained.

ルブ33で調整できる。 Among the greenhouse heating methods described above, in the heat collection process, the distribution of the heat medium circulated between the heat collector 1 side and the heat exchange pipe 4 side is determined by the most efficient distribution depending on the strength of the sunlight during the day. Make sure it can collect heat well. That is, in terms of heat collection efficiency, the heat collector 1 is far superior to the heat exchange pipe 4.
It is more efficient to increase the circulation amount on the heat collector 1 side, but if there is solar heat that exceeds the capacity of the heat collector 1, or if you want to actively achieve the cooling effect inside the vinyl tunnel T, heat exchange It is better to have a relatively large circulation amount on the pipe 4 side, and the distribution of the heat medium can be adjusted using the two-way joint 32 or the control valve 33 on the heat collector 1 side.

32, control valve 33, etc., electrically controlled by the control panel 2 based on information detected by the temperature sensor 10, etc., more efficient heating can be achieved. Also,
A temperature sensor is also installed on the vinyl tunnel T side that will serve as the greenhouse, and the temperature sensor is installed between the heat exchange pipe 4 and the heat collector 1.
A temperature sensor detects both temperature conditions at the same time,
A more suitable implementation would be if the circulation of the heat medium is controlled.

してもよい。 Next, in the daytime heat collection process, it is not necessary to constantly circulate the heat medium to the heat exchange pipe 4 side, and only during times when the sun's rays are strong, the heat medium is supplied to both the heat exchange pipe 4 and the heat collector 1. If the amount of heat collected is increased by circulating the heat, and the sunlight becomes weak, the circulation on the heat exchange pipe 4 side may be stopped and the heat may be collected only by the highly efficient heat collector 1.

At the same time, the heat is circulated between the heat storage tank 3 and the heat exchange pipe 4, and the heat is not only collected by the heat collector 4, but also poured into the greenhouse where the heat exchange pipe 4 is installed. It also utilizes solar heat and can efficiently collect a larger amount of solar heat.

In some cases, the sun's heat may become so intense that the temperature rises to such an extent that the greenhouse must be opened and ventilated to cool the greenhouse.
