[Industrial Application Field] The present invention relates to a cooling device for a greenhouse used for cultivating plants. [Conventional technology] Conventionally, this type of cooling device has been
The one described in Publication No. -50752 is known. [Problems to be Solved by the Invention] However, the above conventional technology has the following problems. Because the water source is a water pipe, the temperature of the water sprayed into the greenhouse is too high. Therefore, the cooling efficiency is not good. After spraying, in order to drain the water to the outside of the greenhouse,
In order to continue cooling, paid tap water must be supplied one after another. Therefore, economic efficiency is not good. [Means for Solving the Problems] In view of the above points, the present invention has been devised for the purpose of increasing cooling efficiency and economic efficiency. An inner roof installed inside the greenhouse, a cold water spraying mechanism that sprays cold water on the upper side of the inner roof, and a cold water dispersion mechanism that circulates the air inside the greenhouse from the top to the bottom of the inner roof and from the bottom to the top. The present invention provides a greenhouse cooling device comprising an air circulation mechanism and using groundwater as the cold water. Further, as shown in claim 2, an inner roof installed inside the greenhouse, a cold water dispersion mechanism for spraying cold water on the upper side of the inner roof, and a cold water dispersion mechanism for distributing cold water on the upper side of the inner roof, and a cooling water dispersion mechanism for distributing the air in the greenhouse from above to below the inner roof. To provide a cooling device for a greenhouse, comprising: an air circulation mechanism for circulating water from the top to the top; a water circulation path for reusing water after watering; and a water cooler installed in the middle of the water circulation path. [Operation] Cold water is sprayed on the upper side of the inner roof installed in the greenhouse, cooling the air above the inner roof and circulating the air inside the greenhouse from the top to the bottom of the inner roof and from the bottom to the top, thereby spreading the entire greenhouse. This action is continued for the required time. There are various types of greenhouses such as glass houses, plastic houses, and vinyl houses, but the present invention does not particularly limit the types of greenhouses. Vinyl in vinyl houses often has light-blocking or heat-insulating properties. The inner roof is preferably one that can be rolled up and erected or suspended in the greenhouse in the form of a tent, and is formed of, for example, polyethylene film, vinyl film, vinyl acetate film, or multilayer film. The cold water distribution mechanism is preferably a sprinkler, which distributes cold water in the form of rain, mist or smoke. A ventilation fan is suitable for the air recirculation mechanism. General tap water or river water can be used as water for spraying, but when using this type of water, it must be cooled before spraying.
This is preferable because there is no need to intentionally cool it. It is efficient to reuse the water that has been sprayed once, by setting up a water circulation path and using a pump to circulate the water, and midway through the process, use a water cooler to re-cool the water. [Example] Next, an example of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, an inner roof 2 is installed inside a greenhouse 1, and a plurality of sprinklers 3 act as a cold water distribution mechanism on the upper surface of the inner roof 2.
ventilation fans 4 and 5 are installed on the upper and lower sides of the inner roof 2, each functioning as an air recirculation mechanism. Greenhouse 1 is a pipe frame with a frontage of 6.0 m, a ridge height of 2.2 m, and a depth of 6.0 m, with a multilayer film of aluminum mixed film and vinyl chloride stretched over the entire surface of the pipe frame, and is equipped with necessary equipment such as an entrance and exit (not shown). The inner roof 2 consists of a pipe frame with a width of 5.0 m, a ridge height of 1.75 m, and a depth of 4.0 m, with a polyethylene film stretched over the top surface of the pipe frame.While the pipe frame has a roughly semicylindrical shape, nothing is stretched over the flat parts at both ends. 6 is a water tank, and the tap water stored in this tank 6 is cooled by a water cooler 7, pumped up to the upper side of the inner roof 2 by a pump 8, and sprayed from a sprinkler 3. The sprinklers 3 are arranged in a line along the piping 9 and are arranged along the depth direction of the inner roof 2. The sprayed cold water falls on the upper surface of the inner roof 2 and cools the air above the inner roof 2 by heat exchange action. The sprayed water flows down along the inner roof 2, is collected in gutters 10 and 11, and is returned to the tank 6 for reuse. The ventilation fans 4 and 5 blow air in the directions indicated by the arrows, and the directions are opposite to each other, circulating the air inside the greenhouse 1 from the top to the bottom of the inner roof 2, and by spraying cold water. The cooled air above the inner roof 2 is introduced to the lower side of the inner roof 2 to cool the entire inside of the greenhouse 1 (FIG. 4). When the greenhouse 1 is a multi-building house as shown in Fig. 5, an inner roof 2, a sprinkler 3, and ventilation fans 4, 5 are installed in each house 1, but the tank 6 and water cooler 7 must be shared. is possible. As mentioned above, it is possible to use groundwater for cooling water, and if there is an abundance of groundwater, it may be discharged as is after spraying. Groundwater is generally cold and often does not need to be cooled. The inventors of the present invention used this groundwater to measure temperature changes. The table below shows the results. The temperature of groundwater at the start of watering was 17.3℃
It was hot.

As explained above, the greenhouse cooling device of the present invention sprays cold water on the upper side of the inner roof installed in the greenhouse to cool the air above the inner roof, and also cools the air inside the greenhouse from above the inner roof. This system circulates air from the bottom to the top and uses sensible heat to cool the entire greenhouse, making it possible to efficiently cool the inside of the greenhouse. It also has the following effects. When underground water is used as cold water based on the configuration according to claim 1, since the temperature of the underground water is low from the beginning, a sufficient cooling effect is achieved, and the cooling efficiency is improved compared to the conventional technology. be able to. Furthermore, when a water cooler is installed in the middle of the water circulation path based on the configuration of claim 2, the water temperature can be controlled to a low level, thereby producing a sufficient cooling effect, compared to the conventional technology. cooling efficiency can be improved. When groundwater is used as cold water based on the configuration according to claim 1, although there are environmental issues to be taken into account, since free water is used, economic efficiency can be improved compared to the conventional technology. . Furthermore, when a water circulation path for reusing water after watering is provided based on the structure of claim 2,
Due to the in-situ reuse of water, economic efficiency can be improved compared to conventional technology.
