Description

Semi-basement type greenhouse

The present invention relates to a greenhouse, and more particularly, to a ring-type greenhouse that minimizes the energy consumed in greenhouse operation by improving the internal temperature of the greenhouse by improving the greenhouse structure.

The greenhouse is a structure that can artificially control light, temperature and humidity suitable for crops such as vegetables and flowers. It is used for the cultivation of various crops. Especially in Korea where four seasons are clear, Is widely used for the cultivation of non-cultivable crops.

However, in many cases, it is difficult to adequately maintain or control the temperature inside the greenhouse by such a structure alone.

As a technique for keeping the temperature inside the greenhouse at an appropriate level, Patent Document 1 discloses a heating device provided inside the greenhouse to maintain the temperature inside the greenhouse at an appropriate temperature. Such a heating device has recently been used in practice.

However, when the internal temperature of the greenhouse is controlled by such a heating device, the energy consumption is considerable. In fact, the heating cost accounts for 30 to 40% of the operating expenses of the horticultural farmhouse. There is a problem of pollution, and it is necessary to develop technology that uses natural energy such as geothermal heat and solar heat.

 In addition, since 85% of the heating fuel used for cultivating horticultural crops uses oil, the amount of oil consumed per year is about 1.2 million kL, which amounts to about 1.3 trillion won, so that the heating fuel is minimized There is an urgent need for a technology capable of greatly reducing heating costs in winter.

Specifically, the outer rafter 220 and the inner rafter 210 have inner and outer rafters 211 and 221 extending from the bent portion O located at the center thereof to one side end thereof, And each of the rafters 211, 221, 212 and 222 has a shape inclined downward toward the opposite ends of the inner and outer pillars 110 and 120. In this case, the inner and outer rafters 212 and 222, The driving unit 30 is located at the folded portion O between the outer rafter 220 and the inner rafter 210 and can walk or hit the insulating curtains 201 and 202 located on both sides thereof.

Further, in another embodiment, the bending portion O 'of the other embodiment is located at a distance from the center of the rafter 200 to one side, preferably about 3/4 of a length from the edge of the rafter 200, Can be of the three-quarter type.

As described above, according to the ring-type greenhouse of the present invention, it is possible to improve the temperature maintenance efficiency inside the greenhouse because it is basically excellent in the warm / cold force compared to the conventional greenhouse.

FIG. 6 and FIG. 7 are graphs comparing these.

As shown in FIG. 6, the temperature inside the greenhouse during the winter night between 19:00 and 08:00 was higher than that of the existing greenhouses, and the lower the outside average temperature was, the higher the warming effect was.

Also, as shown in Fig. 7, the temperature between 09:00 and 18:00 during the winter season can be kept lower than that of the existing greenhouse, thereby reducing the high temperature stress of the crop.

As shown in the following Table 1, it can be seen that it can contribute to the reduction of the heating cost of the greenhouse in winter. When the cost efficiency of conventional greenhouses was 100.0 in the cultivation test for the actual tomato greenhouse, the heating cost of the ring-type greenhouse according to the present invention was 77.0, which was about 23% But it is expected to reduce the heating cost by 20 ~ 30% compared to the conventional greenhouse.

In addition, the above-mentioned temperature holding effect can be achieved by the effect of the temperature drop during the day and the effect of keeping the night during the night due to the hot summer geothermal heat of summer.
