Of course, a section of the insulating layer 113 can be flexibly controlled to be unfolded or rolled according to the requirement.

A plurality of sealing layers of the greenhouse system are located at the joint of two adjacent insulating layers, as shown in fig. 4, taking two adjacent insulating

layers

113a and 113b as an example, a sealing layer 11 is arranged at the edge of the insulating layer 113a, a sealing layer 12 is arranged at the edge of the insulating layer 113b, and a part through which the supporting column 300 passes needs to be reserved after the adjacent sealing layers 11 and 12 are fixedly connected.

As shown in fig. 2a and 2b, the greenhouse system further comprises: the heat storage device comprises a pipe network, a gas delivery pipe 610, a gas transmission pipe 620 and a fan 500, wherein at least part of the pipe network is positioned in the heat storage layer 200, the gas delivery pipe 610 is respectively communicated with the pipe network and the chamber 101, the gas transmission pipe 620 is respectively communicated with the pipe network and the chamber 101, and the fan 500 is positioned in the chamber 101 and positioned on the gas delivery pipe 610. The pipe network is communicated with the chamber 101, so that gas in the pipe network and gas in the chamber 101 are exchanged, and the gas in the pipe network is exchanged with heat storage layer 200 through the pipe wall of the pipe network.

In the present embodiment, the pipe network has 3 layers, and each layer of the pipe network has a plurality of pipes. Specifically, a plurality of first pipelines 601 form a first pipeline network, a plurality of second pipelines 602 form a second pipeline network, and a plurality of third pipelines 630 form a third pipeline network.

Preferably, the material of the thermal storage layer 200 is soil, and the distances between the first pipe 601, the second pipe 602 and the third pipe 630 and the upper surface 1 of the thermal storage layer are 40cm-60cm, 80cm-100cm and 120cm-160cm, respectively. In order to reduce the heat conduction between the pipe network and the soil, a thermal insulation layer may be arranged at the bottom of the thermal storage layer 200, for example, the thermal insulation layer is arranged in the soil with the depth of 180cm-250 cm.

However, the present embodiment is not limited thereto, and those skilled in the art may make other settings for the number of layers and the burying depth of the pipe network according to the needs.

When the temperature outside the greenhouse system is high, the gas inside the chamber 101 heats up. At this point, valve 631 is opened and fan 500 is started. Gas inside the chamber 101 enters the first conduit 601 through the gas delivery conduit 610. The gas sent into the first pipeline 601 exchanges heat with the heat storage layer 200 through the pipe wall of the pipe network, and the heat is dissipated into the heat storage layer 200. The gas inside the first conduit 601 continues to return to the chamber 101 via the gas delivery conduit 620 under the influence of the blower 500. A large amount of heat is stored in the thermal storage layer 200 over multiple cycles.

The above embodiment only illustrates the case where the chamber 101 is communicated with the first pipe network 104 through the valve 631, and in some other embodiments, the heat energy can be supplied to the soil in the lower layer, the middle layer and the upper layer sequentially by controlling the opening and closing of the

valves

631, 632 and 633. When the temperature in the chamber 101 is too high, the total amount and the speed of the gas in the chamber 101 entering the pipe network can be increased by the fan 500, so that the three layers of pipe networks simultaneously supply heat to the heat storage layer 200, 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 chamber 101 drops, and the heat in the heat storage layer 200 is dissipated into the first pipeline 601 through the pipe wall of the pipeline network to exchange heat with the gas in the first pipeline 601. The blower 500 is activated, the gas inside the chamber 101 enters the first conduit 601 through the gas delivery conduit 610, and the gas inside the first piping network continues to return to the chamber 101 through the gas delivery conduit 620 under the action of the blower 500. After many cycles, a large amount of heat stored in the thermal storage layer 200 enters the chamber 101, and it is ensured that the temperature change in the chamber 101 is controlled within a small range.

The above embodiment only illustrates the case where the chamber 101 communicates with the first piping network via the valve 631. Correspondingly, the opening and closing of the

valves

631, 632 and 633 and the rotating speed of the fan 500 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 chamber 101 are increased, the three pipeline networks supply heat simultaneously, and the heat release efficiency of the soil is increased.

In some other embodiments, a temperature control device may be further disposed in the chamber 101 for controlling the temperature difference between the gas in the pipeline network and the thermal storage layer 200. The temperature control device can be used for heating gas in a pipeline network by integrating heat sources (electricity, gas, coal, biomass and the like) so as to improve the temperature difference, thereby improving the heat exchange efficiency and increasing the dehumidification effect. The carbon dioxide generated by the combustion and warming can provide nutrition to the crops in the chamber 101, so that the yield of the crops is improved.

A ventilation structure communicating the chamber 101 with the environment outside the chamber may also be provided in the greenhouse system for exchanging gases outside the chamber with the chamber 101. In some embodiments, the ventilation structure may be a heat exchanger.
