DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] In this document, reference to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. Those skilled in the art will appreciate that the embodiments described herein are merely examples of the application and are not the only way in which the application can be practiced.

[0029] Reference Figure 1 and Figure 2 The present application provides a greenhouse air temperature and humidity adjusting system applied to a greenhouse, wherein the greenhouse comprises a side wall 31 and an arched shed 11 covering the top of the side wall 31 and constituting a greenhouse space with the side wall 31, and the greenhouse air temperature and humidity adjusting system comprises a heating unit, a heat storage unit and a dehumidification unit.

[0030] Specifically, the greenhouse comprises a side wall 31 and an arched shed 11 structure covering the top of the side wall 31 and constituting a greenhouse space with the side wall 31. This arched shed 11 design is usually used to enhance the structural stability of the greenhouse and optimize the utilization of the internal space. The heating unit is used to convert external energy into heat and release it into the greenhouse to maintain a suitable temperature environment; the heat storage unit is used to store excess heat for release when needed, thereby maintaining the temperature stability in the greenhouse; and the dehumidification unit is used to reduce the air humidity in the greenhouse to prevent the influence of the high-temperature environment on crops.

[0031] The heat supply unit comprises a trough-shaped mirror surface 21, a heat collecting pipe 22 and a loop heat pipe 23. The trough-shaped mirror surface 21 is arranged on the top of the side wall 31. The heat collecting pipe 22 is arranged on the trough-shaped mirror surface 21 and is adapted to collect heat collected by the trough-shaped mirror surface 21. The loop heat pipe 23 comprises a first pipe body and a second pipe body which are connected in communication. The first pipe body is coaxially arranged with the heat collecting pipe 22 and is coupled inside the heat collecting pipe 22. The second pipe body is arranged inside the side wall 31.

[0032] The trough-shaped mirror surface 21 is arranged on the top of the side wall 31 of the greenhouse. The trough-shaped mirror surface 21 is curved in a parabolic shape and is adapted to reflect and concentrate sunlight on the heat collecting pipe 22, thereby improving the utilization efficiency of energy. The first pipe body of the loop heat pipe 23 is coaxially arranged with the heat collecting pipe 22 and is coupled inside the heat collecting pipe 22. Therefore, the heat energy in the heat collecting pipe 22 can be directly obtained and transmitted to the second pipe body, i.e. the inside of the side wall 31, through the pipe of the loop heat pipe 23. The heat energy is collected, transmitted and stored based on the heat storage performance of the side wall 31. The heat supply unit of the embodiment not only makes full use of natural energy, but also realizes efficient transmission and layout of heat energy through reasonable structural layout, thereby improving the temperature control effect of the greenhouse.

[0033] The heat storage unit comprises the side wall 31, a heat insulation layer 32 and a heat insulation cotton quilt 33. The heat insulation layer 32 is arranged on the wall surface of the side wall 31 outside the greenhouse space. The heat insulation cotton quilt 33 is arranged above the arched shed 11 and is adapted to cover the arched shed 11 when unfolded.

[0034] Needless to say, the side wall 31 is the main structural part of the greenhouse and not only provides support and maintenance functions, but also plays a role in heat storage in the heat storage unit. The heat insulation layer on the surface of the side wall 31 outside the greenhouse is made of high-efficiency heat insulation material and can effectively prevent cold air from the outside from entering the greenhouse and reduce the loss of heat inside the greenhouse. The heat insulation cotton quilt 33 arranged above the arched shed 11 can prevent heat from rapidly dissipating from the top at night or in a low-temperature environment. In cold or night conditions, the heat insulation cotton quilt 33 can cover the arched shed 11 when unfolded, thereby further improving the heat insulation effect inside the greenhouse.

[0035] The dehumidification unit comprises a dehumidification heat exchanger 41 and a fan group 42. The dehumidification heat exchanger 41 is arranged inside the greenhouse space. The fan group 42 is arranged on the surface of the dehumidification heat exchanger 41.

[0036] The dehumidification heat exchanger 41 can condense or absorb the humid air inside the greenhouse through cooling or adsorption, thereby reducing the relative humidity inside the greenhouse. The fan group 42 arranged on the surface of the dehumidification heat exchanger 41 can accelerate the flow of air and enhance the dehumidification effect.

[0037] Compared with the prior art, the utility model discloses the beneficial effect is: the groove type reflector 21 of heat supply unit in the side wall 31 top can gather the sunlight on the heat collecting pipe 22 in daytime, thereby realizes the efficient absorption of heat, the first pipe body of loop heat pipe 23 is coupled in the heat collecting pipe 22 inside, and the second pipe body is arranged in the side wall 31 inside, so that heat is gathered on the heat collecting pipe 22, is transmitted to the inside of side wall 31 through loop heat pipe 23 after gathering, thereby the heat that collects in daytime is transferred to the side wall 31, utilizes the heat storage capacity of side wall 31, improves the thermal efficiency of greenhouse, and the heat preservation layer 32 of arranging on the outer surface of side wall 31 can reduce wall body heat conductivity, avoid the large loss of heat, the heat preservation cotton quilt 33 covered on the arched shed 11 can reduce the dissipation of greenhouse heat when the outdoor temperature is lower, the fan group 42 of dehumidification unit can increase the circulation of air when the humidity in greenhouse is higher, and utilizes dehumidification heat exchanger 41 to dehumidify the air in greenhouse, to improve the dehumidification effect of greenhouse. The utility model discloses the collocation of heat supply unit, heat storage unit and dehumidification unit can comprehensively regulate and control the air temperature and humidity in greenhouse, improve the dehumidification and heat preservation capacity of greenhouse.

[0038] In the embodiment, the side wall 31 includes a heat storage layer 311 and a solid block layer 312, the heat storage layer 311 is located on the side close to the inside of the greenhouse space, the solid block layer 312 is located between the heat storage layer 311 and the heat preservation layer 312, and the second pipe body is distributed between the heat storage layer 311 and the solid block layer 312 and adheres to the heat storage layer 311 and the solid block layer 312.

[0039] The second pipe body is distributed between the heat storage layer 311 and the solid block layer 312, so that the second pipe body can efficiently transfer the heat from the heat supply unit. During the heat supply process, the second pipe body transfers the heat from the heat collecting pipe 22 to the heat storage layer 311, so that the heat storage layer 311 stores and gradually releases the heat after absorbing the heat, to maintain the temperature inside the greenhouse.

[0040] Further, the heat storage layer 311 is made of a mixture of cement mortar and paraffin-based material, stores the heat energy transferred by the loop heat pipe 23 during the day, absorbs the heat during the day and undergoes phase change, thereby storing the heat energy inside the material; and releases the stored heat energy to the inside of the greenhouse at night, so that the phase change material releases the heat at night and returns to the original phase state, thereby increasing the temperature inside the greenhouse. The heat preservation layer 32 adopts a composite magnesium silicate aluminum insulation material wall integrated structure, which greatly reduces the heat conductivity of the wall. The composite magnesium silicate aluminum insulation material uses inorganic materials such as palygorskite, sepiolite, bentonite and ceramic fiber as main raw materials, removes the harmful substance rock wool on the basis of the original magnesium silicate insulation material, and has the advantages of non-combustibility, environmental protection and long service life.

[0041] Optionally, the loop heat pipe 23 is filled with circulating medium. When the heat collector 22 absorbs the solar energy collected by the trough-shaped reflector 21, the heat in the heat collector 22 is transferred to the first pipe body of the loop heat pipe 23 inside the heat collector 22. At this time, the circulating medium inside the first pipe body is heated and evaporated, and the circulating medium absorbs heat during the evaporation process. After sinking under gravity, the circulating medium in the second pipe body between the heat storage layer 311 and the solid block layer 312 is condensed and releases heat, and then rises through capillary action, thereby forming a heat circulation system in the heat pipe. The circulating medium includes water, ethylene glycol or special refrigerant.

[0042] In the embodiment, the greenhouse air temperature and humidity regulation control system further comprises a support frame, and the trough-shaped reflector 21 is fixed above the side wall 31 by the support frame. Through the support frame, the angle of the trough-shaped reflector 21 can be accurately adjusted to maximize the collection of sunlight; the support frame is fixed above the side wall 31 of the greenhouse, so that the trough-shaped reflector 21 can effectively cover the top area of the side wall 31. Such a layout not only optimizes the light receiving area of the trough-shaped reflector 21, but also ensures that the heat collector 22 and the loop heat pipe 23 can maximize the absorption and utilization of the heat collected by the trough-shaped reflector 21.

[0043] Referring to Figure 3 , the dehumidification heat exchanger 41 is installed in the middle of the top end of the arched shed 11, and the dehumidification heat exchanger 41 comprises a first dehumidification heat exchange layer 411 and a second dehumidification heat exchange layer 412 which are alternately stacked, the first dehumidification heat exchange layer 411 comprises two first baffles oppositely arranged on the outside and a plurality of first fins 411a distributed in parallel between the two first baffles, and the second dehumidification heat exchange layer 412 comprises two second baffles oppositely arranged on the outside and a plurality of second fins 412a distributed in parallel between the two second baffles.

[0044] Among them, the extension direction of the first fin 411a is perpendicular to the extension direction of the second fin 412a.

[0045] The multi-layer stacking and fin interlaced arrangement design of the embodiment enables the dehumidification heat exchanger 41 to achieve maximum dehumidification and heat exchange effect in a limited volume. By optimizing the air flow path and heat exchange process, the dehumidification heat exchanger 41 can effectively reduce the humidity in the greenhouse, while reusing the heat released during condensation to avoid the influence of too low temperature on crop growth.

[0046] Further, the surfaces of the first fin 411a and the second fin 412a are adhered with solid desiccant.

[0047] The solid desiccant here is made of fine-pored silica gel and coarse-pored silica gel, and can achieve maximum dehumidification efficiency and excellent dehumidification capacity under different air humidity conditions.

[0048] Optionally, a first air duct is formed between two adjacent first fins (411a), a second air duct is formed between two adjacent second fins (412a), the dehumidification heat exchanger (41) comprises a first air inlet surface at one end of the first air duct and a second air inlet surface at one end of the second air duct, and the fan group (42) comprises a first fan and a second fan.

[0049] The first fan is attached to the first air inlet surface, and the second fan is attached to the second air inlet surface.

[0050] The dehumidification heat exchanger 41 further optimizes the air flow path and dehumidification effect. A first air duct is formed between two adjacent first fins (411a), a second air duct is formed between two adjacent second fins (412a), and corresponding first and second fans are configured. This dual-fan design ensures that air can be introduced from different directions into the dehumidification heat exchanger 41 and undergo sufficient dehumidification and heat exchange treatment as it passes through the fins and desiccant layers. Through this configuration, air can form a multi-directional flow path as it passes through the dehumidification heat exchanger 41. This multi-directional air flow not only increases the processing capacity of the dehumidification heat exchanger 41, but also ensures that the humidity in the air is more evenly distributed on the first fins 411a and the second fins 412a, thereby further improving dehumidification efficiency.

[0051] Referring to Figure 4 , the greenhouse air temperature and humidity regulation control system further comprises a first air flow pipe 51 and a second air flow pipe 52. The two ends of the first air flow pipe 51 are respectively in communication with the dehumidification heat exchanger 41 and the heat collecting pipe 22. The two ends of the second air flow pipe 52 are respectively in communication with the heat collecting pipe 22 and the greenhouse space.

[0052] Specifically, the dehumidification heat exchanger 41 works in conjunction with the heat collecting pipe 22 to achieve the linkage of dehumidification and heating. Through the connection of the air flow pipes, dry and heated air can quickly enter the greenhouse, avoiding the problem of humidity rising or temperature being insufficient. After these treatment processes, the air has reduced humidity and increased temperature, significantly improving the air quality in the greenhouse and providing a more suitable growing environment for crops.

[0053] Further, the air outlet surface of the dehumidification heat exchanger 41 is communicated with one end of the first air flow pipe, that is, the air in the greenhouse enters the first air inlet surface and the second air inlet surface of the dehumidification heat exchanger 41, after the dehumidification and heat exchange treatment of the dehumidification heat exchanger 41, enters the first air flow pipe 51 through the air outlet surface, absorbs heat through the heat collecting pipe 22, is transmitted through the second air flow pipe 52 and enters the greenhouse space, so that the dehumidification and heating of the air in the greenhouse are realized.

[0054] Optionally, a circular hole matched with the second air flow pipe 52 is formed on the floor of the ground of the greenhouse space, one end of the second air flow pipe 52 extends to the greenhouse through the circular hole, and the other end of the second air flow pipe 52 is communicated with the heat collecting pipe 22.

[0055] The utility model further optimizes the installation mode of the second air flow pipe 52, sets the floor on the greenhouse ground, forms the circular hole matched with the second air flow pipe 52 on the floor, and makes the air flow path more reasonable and concealed.

[0056] In an embodiment, the system further comprises a temperature sensor, a humidity sensor, a control unit and a thermal cotton quilt opening and closing mechanism.

[0057] The temperature sensor and the humidity sensor are installed in the greenhouse space, one end of the control unit is electrically connected with the temperature sensor and the humidity sensor, and the other end of the control unit is electrically connected with the thermal cotton quilt opening and closing mechanism and the fan group 42.
