Description

[0001] The present invention relates to a double-greenhouse temperature management system,

The present invention relates to a double-vinyl house temperature control system, and more particularly, to a double-vinyl house temperature control system, which is capable of maintaining a constant temperature inside a house by forming an outer- To a temperature control system for a double vinyl house.

In general, house cultivation is common in farmhouses in order to cultivate crops regardless of season.

Especially, greenhouse cultivation is a typical example of greenhouse cultivation and vinyl house cultivation. However, glasshouse is advantageous in various parts, but it is expensive and difficult to install.

The vinyl house is generally constructed by covering a pipe with a plastic and covering the outside with vinyl, and it is variously provided according to the shape of the roof, typically a semi-circular roof.

Because the vinyl house is somewhat low in thermal insulation due to the nature of the vinyl, it is difficult to maintain the internal temperature of the vinyl house properly or to maintain the temperature of the culture soil at the proper temperature. Therefore, the vinyl house is mainly composed of a double vinyl house It is generally used.

The double vinyl house is buffered so that the external temperature is not directly transmitted to the inside between the inner vinyl and the outer vinyl so that the temperature inside the vinyl house does not change abruptly. However, , Which can lead to a more serious situation, and various complementary measures are being applied accordingly.

In other words, in the case of the winter season, the space of the double vinyl house functions to prevent the outside air from being directly transmitted to the inside. However, in order to maintain the temperature suitable for growth of the cultivated crop, The heating cost used at this time is an excessive economic burden on the farmhouse.

Also, in the case of the summer season, since the temperature of the thermal insulation space rises higher than the outside temperature, the internal temperature is raised. Therefore, a separate ventilation facility is installed or the lower end of the vinyl house is raised to a certain height so that ventilation is performed. Temperature management is impossible.

In order to solve this problem, a public utility model 2013-0006044 (entitled "Dual Thermo-Vinyl House") is provided to allow cool air or warm air to be supplied from one side to the inside and outside of the vinyl, The inside of the house is communicated with the outside through a ventilator so that ventilation can be performed.

That is, in the prior art, the warm air or cool air is supplied to the inside and the outside of the vinyl house from one side of the vinyl house, and the warm air and the cool air supplied from the other side are forcibly discharged while ventilating the inside of the plastic house. Environment.

However, in the prior art, a sudden temperature difference in the course of warm or cold air flowing from one side of the vinyl house to the other side is inevitable, so that there is a problem that uniform temperature control is impossible due to the temperature difference on both sides inside the vinyl house.

In addition, heat loss through the vinyl cladding material and heat loss through the soil also cause uneconomical problems in that the fuel cost for maintaining the inside temperature of the vinyl house is still excessively high.

The public utility model 2013-0006044 (22013.10.17.)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a temperature control system for a double vinyl house according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view illustrating a temperature control system for a double vinyl house according to the present invention. FIG. 2 is an enlarged cross-sectional view of a double-vinyl house temperature management system according to the present invention. The inner space of the inner vinyl 110 is separated from the inner space of the crop growing space S1 by the inner vinyl 11 and the outer vinyl 12, So that the temperature can be maintained constant.

The inner vinyl 11 and the outer vinyl 12 of the double vinyl house 10 have inner frames 13 each having a different outer diameter and being bent in the same shape so as to be spaced apart from each other by a predetermined distance, And outer sides of the outer frames 14, respectively.

At this time, the inner frames 13 and the outer frames 14 are spaced apart from each other along the inner main surface to be connected by the inner frame connecting bars 15 and the outer frame connecting bars 16 in the longitudinal direction , And the intersecting portions between the frames (13, 14) and the connecting bars (15, 16) are fixedly connected to each other by separate fasteners (not shown).

Therefore, a space is formed between the inner vinyl 11 and the outer vinyl 12 so as to be spaced apart from each other along the main surface so that the crop growing space S1 is not directly affected by the outside air, S2) are formed. The structure of the double-vinyl house 10 is greatly different from that of the past.

However, the present invention is intended to maximally prevent heat loss in the crop growing space S1 of the double-vinyl house 10.

To this end, the temperature control system for a double vinyl house according to the present invention comprises a supply unit 20, a thermal insulation unit 30, a thermal insulation unit 40, a thermal storage unit 50, a sensing unit 60, and a control unit 70 Respectively.

The air supply unit 20 of the present invention further includes a radiator 21 and a cooler 22 and a blower 23 for forcibly sending warm or cool air supplied from the radiator 21 and the cooler 22 to the greenhouse 10, .

The radiator 21 and the radiator 22 selectively operate and may not operate simultaneously depending on the situation. The warm or cool air generated from the radiator 21 and the radiator 22 may be sent to the blower 23 to be forcibly delivered to the greenhouse 10 do.

It is most preferable that the blower 23 is provided so as to be able to adjust the blowing intensity automatically or manually and the blower 23 is provided at a position as close as possible to the position where the warm or cool air from the greenhouse 10 flows.

The warm or cool air supplied from the air supply unit 20 is supplied to the warming space S2 through the warming unit 30. [

3 is an enlarged cross-sectional view illustrating an air supply duct and an exhaust duct in a temperature control system for a double vinyl house according to the present invention.

As shown in the figure, the warming unit 30 includes an air supply duct 31 provided along the bottom of the thermal insulation space S2 between the inner vinyl 11 and the outer vinyl 12, an exhaust duct 32 at the upper end of the thermal storage space S2 ).

The air supply duct 31 is installed along the bottom surface of the heat insulating space S2 so that warm air or cool air supplied from the air blower 23 is injected upward through a plurality of air supply holes 310 formed at regular intervals on the main surface .

Since the supply duct 31 is tubular, it is more preferable to fix the supply duct 31 along the outer frame 14.

The exhaust duct 32 provided at the upper end of the heat insulating space S2 is formed along the entire length of the greenhouse 10 along the outer frame 14 like the air supply duct 31 while a plurality of intake holes 320 are formed so that warm or cool air that flows upward along the warming space S2 flows into the inside.

The warm air or the cool air flowing into the exhaust duct 32 is supplied again to the blower 23 of the air supply unit 20 and the circulating blower 33 is discharged from the exhaust duct 32 It is more preferable to provide the end portion or the pipe at a position close thereto.

4 is an enlarged structural view illustrating a schematic structure of a heat insulating portion and a heat storage portion in a temperature control system for a double vinyl house according to the present invention.

The heat insulating part 40 of the present invention is constructed such that the heat insulating material 41 is buried in a certain depth from the lower end side surface of the heat insulating space S2 so that the outside air is not transmitted to the crop growing space S1 through the ground surface.

At this time, the heat insulating material 41 should be made of a conventional insulating material such as styrofoam, and the depth of buried material is preferably 1 m or more.

The heat accumulating part 50 according to the present invention is provided with a heat collecting plate 51 along the upper surface of the heat insulating material 41 installed along the bottom surface of the heat insulating space S2, The heat accumulating bag 52 is filled with water or a latent heat material so that the heat accumulating bag 52 is housed.

The heat collecting plate 51 is composed of a reflecting plate having a reflector as its upper surface. The aluminum plate is most effective as the heat collecting plate 51.

The heat storage unit 50 is configured to heat the water or latent heat material filled in the heat storage bag 52 by solar heat collected from the sun to the heat collection plate 51 to a predetermined temperature, So as to form a basic temperature.

On the other hand, during the summer season, the temperature of the warming space S2 can be excessively raised by the external heat, so that the cooler air is supplied to the warming space S2 to lower the temperature. It is most preferable that the upper portion of the heat collecting plate 51 is covered by the heat storage bag 52 while discharging the water or the latent heat material from the heat storage bag 52 during the summer season.

However, the water or the latent heat material to be filled in the heat accumulation bag 52 may be continuously supplied to the heat accumulation bag 52 by using a separate solar collecting device 53 outside the greenhouse 10 to heat the fluid to a predetermined temperature or higher It is also possible to arrange such that it is circulated.

The sensing unit 60 of the present invention has a configuration including a first sensor 61 and a second sensor 62 for checking the temperatures of the crop cultivation space S1 and the warming space S2, The first sensor 61 of the heat insulating portion S1 is installed at a position not shifted to one side in the crop cultivation space S1 and the second sensor 62 of the heat insulating space S2 is disposed at a position So as to be installed near the duct 32.

The control unit 70 checks the temperature from the second sensor 62 on the side of the thermal insulation space S2 together with the temperature from the first sensor 61 on the side of the crop growing space S1, ) Is controlled to be equal to or higher than the crop cultivation space S1 by a predetermined temperature.

In the meantime, despite the warming using the heat storage unit 50 and the heater 21 in the warming space S2 of the present invention, the outside air is further lowered in a cold season, and sufficient warmth can not be generated.

In particular, since the warm air supplied to the warming space S2 is supplied at a constant intensity by using the blower 23, if the temperature of the warmer is excessively high, the inner vinyl 11 and the outer vinyl 12 may be damaged, 23 can not be limited to a certain temperature.

5 is a perspective view illustrating a structure in which a heating pipe is applied to a temperature control system for a double vinyl house according to the present invention.

Since the temperature of the air supplied through the air supply unit 20 can not be increased beyond the limit temperature, the space between the inner frame 13 and the outer frame 14 on the upper side of the air supply duct 31 is constant A plurality of heating pipes 80 may be provided so as to extend over the connection ports 17 or separate connecting means to be connected while being spaced apart from each other.

The heating pipe 80 is electrically operated and the heat heated by the heating pipe 80 flows upward by the discharge pressure of the warm air sent out through the air supply duct 31 at the lower part thereof, Let the temperature rise.

The operation and effect of the temperature control system for a double vinyl house according to the present invention will now be described.

6 is a control block diagram of a temperature control system for a double vinyl house according to the present invention. As shown in the figure, the vinyl house 10 of the present invention uses a temperature difference between a crop growing space S1 and a warming space S2 The temperature on the side of the heat insulation space S2 is adjusted to the temperature of the crop growing space S1 so that the heat loss in the crop growing space S1 can be prevented as much as possible.

To explain this in more detail, there is a slight difference depending on the crop to be cultivated, but the optimal temperature is set for the cultivation of the crop.

The advantage of maintaining the cultivation temperature is favored greenhouse cultivation using vinyl house. The problem is that it is not easy to adjust crop cultivation temperature because of the heat loss caused by greenhouse cultivation, and the heating cost required for it is very difficult Remains.

In order to solve such a problem, the present invention allows the heat or cold air to flow into the heat insulating space S2 between the inner vinyl 11 and the outer vinyl 12 so that there is no heat loss through the heat insulating space S2, And a heat insulating portion 41 having a constant height is formed in the lower layer of the space S2 so that the heat loss through the layer is minimized.

The supply of warm or cool air to the warming space S2 is performed by supplying warm or cool air generated from the heater 21 or the cooler 22 of the supply unit 20 to the supply duct 23 of the warming unit 31 using the blower 23, (31).

At this time, the water or the latent heat material filled in the heat accumulation bag 52 is heated by the solar heat using the lower heat collecting plate 51 so that a certain amount of heat can be secured in the heat insulating space S2 basically And a solar collecting device 53 provided outside the greenhouse 10 may be used for securing higher heat quantity by the heat accumulating bag 52.

In other words, if the fluid further heated through the solar collecting device 53 is supplied to the heat accumulation bag 52 and circulated continuously, the heat storage bag 52 is supplied with the higher temperature fluid stably, I will get it.

On the other hand, when the warm air supplied through the heater 21 to the warmth through the heat accumulating bag 52 is supplied to the warming space S2 at the same time, these warmers move from the lower part to the upper part of the heat insulating space S2, So that the temperature gradually decreases.

However, when the air supply duct 31 is supplied with the warm air through the blower 23 and is discharged from the outside of the air exhaust duct 32 through the circulating air blower 33, the warm air moves more quickly, So that there is almost no temperature difference.

By comparing the temperature with the temperature checked by the first sensor 61 on the side of the crop growing space S1 while checking the second sensor 62 provided at the upper end of the warming space S2 flowing into the exhaust duct 32, So that the internal temperature of the heat insulating space S2 is adjusted by the difference.

The control unit 70 checks the temperature from the first sensor 61 and the second sensor 62 to control the heater 21 or the cooler 22 and the blower 23 of the supply unit 20, S2 to be at the same temperature as the temperature of the crop growing space S1.

However, in the case where a large amount of heat or snow is present in the winter season, the heat loss is extremely large even in the warming space S2. Therefore, in the state where control through the heater 21 and the blower 23 is difficult, The temperature in the thermal insulation space S2 is further raised by the heat generated through the heating pipe 80 provided on the upper portion of the outer vinyl 12 to minimize the temperature difference with the crop growing space S1, It can be prevented from accumulating.

As described above, according to the present invention, it is possible to effectively maintain a stable warming even with a relatively low energy cost, thereby further saving the maintenance cost of the vinyl house.

Further, the inner vinyl 11 between the crop cultivation space S1 and the thermal insulation space S2 no longer generates a dew condensation phenomenon, and the temperature can be more easily adjusted.

In this way, the heat loss of the greenhouse 10 can be reduced by 90% or more, so that the heating cost can be reduced and the temperature suitable for growing crops can be stably maintained, thereby greatly increasing the crop yield.
