When the concentration of the exhaust gas (e.g., carbon dioxide, sulfur dioxide, etc.) in the first space 1100 reaches a certain value, the heat exchanger is activated, thereby not only ensuring the oxygen content in the first space 1100, but also reducing the heat loss in the first space 1100.

In some other embodiments, the air inside the first space 1100 and the second space 1200, and the air outside the second space 1200 and the chamber may be replaced by different ventilation structures, as shown in fig. 2. Since the ventilation structure 151 is spaced further from the ventilation structure 152, heat loss in the first space 1100 is further reduced by indirect replacement.

The working principle of the greenhouse system according to the first embodiment of the present invention will be described in detail with reference to fig. 3a and 3 b.

When the temperature outside the greenhouse system is high, the gas inside the second space 1200 is heated, at this time, the valves 11, 13, 16 are opened, the

valves

12, 14, 15, 17, 18, 19, 20, 21 are closed, the fan 141 is started, the gas inside the second space 1200 enters the first pipe network 104 through the air feeding pipe 101 and the bypass pipe 102, the heat in the first pipe network 104 is dissipated into the heat storage layer, the gas inside the first pipe network 104 continues to return to the second space 1200 through the air conveying pipe 107 under the action of the fan 141, wherein the gas flow path is shown by the arrow in fig. 3 a. After many cycles, a large amount of heat can be stored in the heat storage layer, and when the gas in the second space 1200 exchanges with the gas in the first pipe network 104, the first space 1100 is not communicated with the second space 1200, so that the gases in the two spaces do not affect each other, and the temperature change in the first space 1100 is controlled in a small range.

The above embodiment only describes the case where the second space 1200 is communicated with the first pipe network 104, in some specific embodiments, when the greenhouse system is used as a livestock house and starts to operate before winter, on the premise that the temperature inside the livestock house is suitable for the survival of animals, by controlling the opening and closing of the plurality of valves, heat energy is preferentially supplied to the soil on the lower layer, then the middle layer and then the upper layer, and when the temperature inside the second space 1200 is too high, the total amount and the speed of the gas in the second space 1200 entering the pipe network can be increased through the fan 141, so that the three pipe networks simultaneously supply heat, and the heat absorption efficiency of the soil is increased.

When the temperature outside the greenhouse system is low, the temperature of the gas inside the second space 1200 drops, and in order to prevent the chimney effect formed by the plurality of pipe networks in the heat storage layer and the inside of the second space 1200, the valve 11 needs to be closed, and at this time, the valve 11 functions as a check valve. In order to ensure that the temperature variation in the first space 1100 is controlled within a small range, the

valves

12, 13, 19 are opened, the

valves

14, 15, 16, 17, 18, 20, 21 are closed, the fan 141 is started, the gas inside the first space 1100 enters the first pipe network 104 through the gas feeding pipe 101 and the bypass pipe 102, the heat in the heat storage layer is dissipated into the first pipe network 104, and the gas inside the first pipe network 104 continues to return to the first space 1100 through the gas conveying pipe 108 under the action of the fan 141. Wherein the gas flow path is shown by the arrows in figure 3 b. After many cycles, a large amount of heat stored in the thermal storage layer enters the first space 1100, and the temperature change in the first space 1100 is controlled within a small range. When the gas in the first space 1100 exchanges with the gas in the first pipe network 104, the first space 1100 and the second space 1200 are not communicated with each other, and therefore, the gases in the two spaces do not affect each other.

The above embodiment only illustrates the case that the first space 1100 is communicated with the first pipeline network 104, and correspondingly, the opening and closing of the plurality of valves and the rotation speed of the fan 141 can be controlled according to the outdoor temperature, so that the total amount and the speed of the gas in the pipeline network entering the first space 1100 are increased, the three pipeline networks simultaneously supply heat, and the efficiency of soil heat release is increased.

In order to further ensure that the temperature variation inside the first space 1100 is controlled within a small range, the area of the insulating layer 131 covering the second structural layer 120 may be adjusted according to the temperature inside the second space 1200. For example, when sunlight is sufficient and the outdoor temperature is suitable for animals to live, part or all of the insulation layer 131 can be rolled up by the reel 132, so that the sunlight can penetrate through the second structural layer 120 to enter the first space 1100, or when the external sunlight is too strong and the temperature is too high, the insulation layer 131 can be wholly or partially used as a shading material, the temperature of the first space 1100 is reduced, and the influence of the high temperature on the animals is reduced. When the outdoor temperature drops greatly at night or in rainy, snowy and rainy days, the heat-insulating layer 131 is required to cover the whole second structural layer 120 through the scroll 132, so that the heat-insulating effect is achieved.

By the technical means, the temperature in the first space 1100 is always kept in a stable range, so that the temperature is not too cold or too hot, and livestock in the first space 1100 can adapt to the environment well.

According to the greenhouse system provided by the embodiment of the utility model, the chamber is divided into the first space and the second space by the first structural layer and the second structural layer, and the first space is surrounded by the second space; the heat exchange of the gas in the first space and the gas in the second space is realized through the heat storage structure, the heat storage structure is provided with a plurality of gaps for storing the gas, and the gas in the gaps is selectively exchanged with one of the gas in the first space and the gas in the second space, so that the gas in the first space and the gas in the second space cannot be influenced mutually when the gas exchange is carried out, and the temperature change in the first space is controlled in a smaller range.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In accordance with the embodiments of the present invention as set forth above, these embodiments are not exhaustive and do not limit the invention to the precise embodiments described. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and its various embodiments with various modifications as are suited to the particular use contemplated. The present invention is limited only by the claims and their full scope and equivalents.
