More particularly, the present invention relates to a double coated greenhouse, and more particularly to a double coated greenhouse, wherein the distance between the outer coating layer and the inner coating layer constituting the greenhouse is set within 100 mm to suppress the convection phenomenon, the outer screening net is provided at the lower end of the outer coating layer, The present invention relates to a double-coated greenhouse capable of reducing the ventilation energy by a chimney effect while enhancing the effect of keeping warmth and keeping cool by providing an inner screen net.

Generally, a greenhouse such as a greenhouse means a building which is capable of artificially controlling the light, temperature and humidity, which are the main growth environment of the plant. The greenhouse refers to a structure in which the growth of the crops is promoted by forcing cultivation, It is possible to produce agricultural products continuously throughout the year, and special crops that can not be cultivated in open fields can be cultivated and produced. Therefore, it is possible to earn high profit from a certain area and can freely control the growth stages of various crops, It is widely used for breeding (breeding).

In addition, the relationship between environment and crop growth can be studied by controlling the temperature, humidity, light rays, and reaction of crops, and it can be used as educational facility by protecting and nurturing tropical and subtropical plants.

However, greenhouses have disadvantages such as a high cost of facilities and maintenance.

As a conventional technique for solving such drawbacks, Korean Patent Laid-Open Publication No. 2013-0005818 (Patent Document 1) discloses a double thermostatted vinyl house having an outside vinyl house and an inside vinyl house, and is installed at a lower portion of one side of the outside vinyl house A heat exchanger for cooling or heating the outside air using the pumped groundwater as a heat source and a heat exchanger installed integrally with the heat exchanger for sucking the outside air to circulate the cooling air or the heating air to the space between the outside vinyl house and the inner vinyl house A second blower installed at a lower portion of the other side of the outer plastic greenhouse to discharge the circulated cooling air or the heated air to the outside; And the air in the inside of the greenhouse is ventilated Key is the bar offered a dual thermostatic greenhouses, including the fans.

Patent Document 1 has the advantage of improving the heat insulating effect compared to a single-layer vinyl house because it has a double vinyl house structure. However, since air is injected into a space between the outside and the inner greenhouse, And a ventilator for ventilating the inside air is separately required. Therefore, there is a problem in that the electricity consumption is excessive and the maintenance cost can not be reduced.

2 is a perspective view of a double coated greenhouse according to one embodiment of the present invention.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It should be understood, however, that there is no intention to limit the invention to the form just described, and the spirit and scope of the present invention encompasses the ordinary variations, equivalents, and alternatives of the illustrated forms.

FIG. 1 is a cross-sectional view of a double coated greenhouse according to one embodiment of the present invention, and FIG. 2 is a perspective view of a double coated greenhouse according to an embodiment of the present invention.

1 and 2, the double coating greenhouse of the present invention is roughly divided into an outer coating layer 1 having an outer passage 2 and an inner coating layer 3 having an inner passage 4.

The outer coating layer 1 is made of a transparent material capable of transmitting sunlight, for example, a flexible film, an air bubble film filled with air, a synthetic resin plate material, a synthetic resin double-walled plate material, a glass plate material, And at least one outer passage 2 is formed at the bottom portion so that air in the greenhouse outer region S1 flows into the double coated region S2 It is made possible.

The inner coating layer 3 is spaced a predetermined distance from the inside of the outer coating layer 1 so that a double coating region S2 is formed between the inner coating layer 3 and the outer coating layer 1, 1), it is made of a transparent material which can transmit sunlight, for example, a flexible film, an air-blown film filled with air, a synthetic resin plate, a synthetic resin double-walled plate, a glass plate, The inner passage 4 is formed so that air in the double coated region S2 can be introduced into the greenhouse interior region S3.

At this time, if the distance between the outer coating layer 1 and the inner coating layer 3 is narrowly set to 100 mm or less, a chimney effect occurs in the double coating region S2, and convection is suppressed.

That is, when the distance between the outer coating layer 1 and the inner covering layer 3 is large, when the temperature T3 of the greenhouse outer area S1 is higher than the temperature T1 of the greenhouse interior area S3, S2, the temperature of the portion close to the outer coating layer 1 rises and the temperature of the portion close to the inner covering layer 3 falls, and a convection phenomenon occurs due to a change in air pressure depending on the temperature difference. Therefore, in order to reduce the heat loss due to the convection, it is desirable that the distance between the outer coating layer 1 and the inner coating layer 3 is narrowed to 100 mm or less so that convection does not occur.

It is also possible to prevent insects in the greenhouse outer area S1 from entering the greenhouse interior area S3 by forming insect control nets in the outer passage 2 and the inner passage 4, There is no restriction on the type and the form of the pest, provided that the pest can be prevented from invading smoothly.

Further, a first ventilation window (5) such as a window is installed on the upper part of the greenhouse (the upper end of the greenhouse possible) so as to ventilate the air in the greenhouse interior area (S3) A second ventilation window 6 such as a window is provided at the lower portion of the greenhouse (the lowest end of the greenhouse as far as possible), and the second ventilation window 6 is also provided in the first ventilation window 5 in the form of a sliding door or a hinged door, So that the first ventilation window 5 and the second ventilation window 6 can be opened or closed as necessary.

Of course, the first ventilation window 5 and the second ventilation window 6 may be further provided with ventilators (not shown) for smooth ventilation.

In order to constitute the double coating greenhouses of the outer coating layer 1 and the inner coating layer 3, for example, a plurality of basic frame frames 10 are provided at regular intervals in an arch shape as shown in Fig. 2, A plurality of outer pads 11 are provided in the lateral direction on the outer surface of the frame 10 and a plurality of inner pads 12 are provided on the inner surface of the frame 10 in the transverse direction.

Thereafter, the outer coating layer 1 is provided on the outer pad 11 and the inner coating layer 3 is provided on the inner pad 12. The outer coating layer 1 is provided between the outer coating layer 1 and the inner coating layer 3, A double coated region S2 spaced apart by the thickness of the substrate 10 may be formed.

Of course, the configuration of the greenhouse can be variously designed according to the type and material of each coating layer (1) and (3), and thus is not limited to the configuration of FIG.

Hereinafter, the operating relationship of the greenhouse will be described with reference to FIG. 1, and the present invention will be further detailed.

(1) In the day when the sunlight is irradiated during the winter season, since the air in the double coated region S2 is heated by the solar energy Q, the temperature relationship in each region is as follows.

T2> T0> T1> T3

T0 is the set temperature (desired temperature inside the greenhouse), T1 is the inside temperature of the greenhouse, T2 is the inflow air temperature (air temperature in the double coating region), and T3 is the outside temperature of the greenhouse.

Since the air temperature T2 in the double covering region S2 is higher than the outside temperature T3 of the greenhouse and the inside temperature T1 of the greenhouse because the air temperature is increased by the solar energy Q, The heated air in the inside of the greenhouse is raised upward by the chimney effect and flows into the greenhouse interior area S3 through the inner passage 4. [

That is, when the air inside the double coated region S2 is heated by the solar energy Q, the air inside the heated double coated region moves to the upper layer. When the air temperature on the upper side of the double coated region S2 becomes higher than the temperature T1 of the inside region S3 of the greenhouse, the air pressure on the upper side of the double covered region S2 becomes higher than the air pressure in the greenhouse internal region S3, The air on the upper side of the region S2 flows into the greenhouse interior region S3 and then the air in the greenhouse exterior region S1 is sucked into the double covered region S2 and a so-called chimney effect is generated.

At this time, as described above, if the width of the double coated region S2 is too large, the convection phenomenon may occur and the chimney effect may be reduced or may not occur. Therefore, the separation distance between the outer coating layer 1 and the inner coating layer 3 should be designed as narrow as possible .

The warm air introduced into the greenhouse interior area S3 increases the greenhouse interior temperature T1 lower than the set temperature T0 and raises the air in the greenhouse interior area S3 close to the set temperature T0, . ≪ / RTI >

In this case, the first ventilation window 5 located on the uppermost greenhouse should be closed so that the hot air in the greenhouse interior area S3 does not flow out to the outside. On the contrary, the second ventilation window 6 located on the lowermost side of the greenhouse is opened Allow for ventilation.

(2) Since there is no solar energy (Q) in the case that the sunlight is not irradiated during the winter season, that is, when there is no sunlight or cloudy daytime, the temperature relationship in each region is as follows.

T0> T1> T2> T3

As described above, the temperature T3 of the greenhouse is the lowest, the temperature T2 of the double coated region S2 next to the greenhouse outside region S1 is low, and the greenhouse internal temperature T1 is relatively low Since the outer passage 2 is located in the lower portion of the greenhouse and the inner passage 4 is located in the upper portion of the greenhouse in the state where the temperature of the outer space 2 is higher than the temperature of the region S2, Is not introduced into the greenhouse interior area S3 (c). That is, the double coated region S2 in which the convection phenomenon is suppressed functions to block the inflow of the greenhouse outside region S1, thereby preventing the temperature of the greenhouse inside region S3 from being lowered.

At this time, both the first ventilation window 5 and the second ventilation window 6 should be closed to prevent hot air in the greenhouse interior area S3 from flowing out.

(3) In the case of spring / autumn, since the air in the double covering region (S2) is heated by the solar energy (Q) in the daytime, the temperature relationship in each region is as follows.

T2> T0> T1> T3

Since the air temperature in the double coated region S2 is higher than the greenhouse external temperature T3 and the greenhouse internal temperature T1, the heated air in the double covered region S2 rises upward due to the chimney effect, 4) to the interior region S3 of the greenhouse.

The warm air thus introduced into the greenhouse interior region S3 can increase the greenhouse interior temperature T1 lower than the set temperature T0.

At this time, if the internal temperature T1 of the greenhouse is lower than the preset temperature T0, the first ventilation window 5 should be closed to prevent the hot air in the interior region S3 of the greenhouse from flowing out, If it is higher than the set temperature T0, both the first ventilation window 5 and the second ventilation window 6 should be opened to forcibly discharge warm air in the greenhouse interior area S3 to the outside.

(4) When the summer sunlight is irradiated, the inside temperature T1 of the greenhouse is lower than the outside temperature T3 of the greenhouse due to the heat insulating action of the double covering region S2, ) Are heated, so the temperature relations in each region are as follows.

T2> T3> T1> T0

The air in the double coated region S2 is heated to a temperature higher than the greenhouse inner temperature T1 and the set temperature T0 and flows into the greenhouse interior region S3 through the inner passage 4 by the chimney effect, As a result, the temperature inside the greenhouse (T1) rises higher than the set temperature (T0), causing high temperature damage in the growth of the crop.

Accordingly, both the first ventilation window 5 and the second ventilation window 6 should be opened so that hot air in the greenhouse interior area S3 flows out to the greenhouse outside area S1 to lower the greenhouse interior temperature T1.

At this time, the hot air in the greenhouse interior area S3 is moved upward, and the first ventilation window 5 is located on the uppermost side of the greenhouse, so that hot air can be quickly discharged through the first ventilation window 5, The air in the outside region S1 of the greenhouse flows into the inside region S3 of the greenhouse through the air circulation path 6 so that the proper temperature is maintained by the air circulation.

(5) Summer daytime temperature is always higher than nighttime, and summer daytime outdoor temperature is higher than the set temperature (T0) suitable for cropping. Further, since the interior of the greenhouse is heated by the sunlight, the temperature T1 of the interior region S3 of the greenhouse is higher than the temperature T3 of the exterior region S1 of the greenhouse.

The temperature T3 of the outside region S1 of the greenhouse is lowered at the night of the summer, and the temperature gradually falls from the region contacting the outside region S1 of the greenhouse.

T1> T0> T2> T3

In this case, the lower air having a relatively high temperature in the greenhouse interior area S1 is moved upward. At this time, the first ventilation window 5 is opened to allow cool air in the greenhouse outside area S1 to flow into the greenhouse interior area S3. The inside temperature T1 of the greenhouse can be lowered by forcing the hot air in the interior region S3 of the greenhouse to flow out to the outside.

At this time, if the outside temperature T3 of the greenhouse is higher than the greenhouse internal temperature T3 and the set temperature T0, the first ventilation window 5 is closed, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims. will be.
