Description

Technical Field

[0001] This invention relates to the field of environmental control technology for edible fungi cultivation, specifically a low-carbon integrated environmental control system for the fruiting period of aerobic edible fungi. Background Technology

[0002] With the increasing frequency of extreme weather events caused by global warming, edible mushroom cultivation is facing significant risks and challenges. Existing environmental control equipment for edible mushrooms is mainly applied to anaerobic varieties, such as enoki mushrooms, king oyster mushrooms, and deer antler mushrooms—specifically, artificially selected varieties adapted to this environment. However, for aerobic varieties, such as commonly cultivated oyster mushrooms, shiitake mushrooms, and enoki mushrooms, as well as rarer varieties like morels and red-topped bamboo fungus, feedback from numerous companies and individuals indicates that existing environmental control equipment produces poor-quality products with extremely high energy consumption. The root cause lies in the conflicting and restrictive factors in the target environment, such as temperature, humidity, and carbon dioxide concentration. Aerobic edible mushroom varieties remain the market mainstream in terms of both taste and consumer preferences. Therefore, minimizing the frequent fluctuations in the target environment caused by the multi-parameter coupling of existing environmental control equipment, and creating the optimal environment for fruiting body growth during the fruiting period of aerobic edible mushrooms, developing integrated environmental control equipment for these varieties has become an urgent priority for the edible mushroom cultivation industry. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a low-carbon integrated environmental control system for the fruiting period of aerobic edible fungi, which solves the problems of poor quality and high energy consumption of aerobic edible fungi produced by existing environmental control equipment.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a low-carbon integrated environmental control system for the fruiting period of aerobic edible fungi, including a planting greenhouse, wherein several exhaust fans are evenly arranged at the lower ends of both sides of the planting greenhouse, and the exhaust fans are equipped with check valves to prevent backflow of strong winds from the outside, and electric valves are provided on the inside to open or close. The planting greenhouse is equipped with an internal circulation refrigeration mechanism and an external circulation refrigeration mechanism. The internal circulation refrigeration mechanism includes an internal circulation fan coil unit fixedly connected to the upper front end of the planting greenhouse. A pair of internal circulation fans are fixedly connected to the front end of the fan coil unit. The air outlets of the left and right internal circulation fans are respectively connected to a right internal circulation four-way valve and a left internal circulation four-way valve. Electric air valves are installed on the three small branch pipes of both the right and left internal circulation four-way valves. The air outlets of the small branch pipes of the right and left internal circulation four-way valves are respectively connected to a right internal circulation fabric distribution duct and a left internal circulation fabric distribution duct. The right side of the material distribution duct is horizontally aligned with the planting greenhouse. Both the right and left internal circulation material distribution ducts are conical. The exhaust fan speed is set to high, medium, and low. The total exhaust volume of each exhaust fan speed is less than the fresh air volume generated by each external circulation fan speed, so that the planting greenhouse can always maintain a slight positive pressure when the equipment is running. There is fast-flowing cold water in the internal circulation fan coil unit. The temperature of the cold water is controlled by the variable frequency ground source heat pump outside the planting greenhouse and the circulating water structure on the internal circulation cooling and insulation water tank. At the same time, both the right and left internal circulation material distribution ducts are conical.

[0005] Preferably, the external circulation refrigeration mechanism includes an external circulation fan coil unit fixedly connected to the middle of the bottom end of the internal circulation fan coil unit. An external circulation fan coil unit window, communicating with the outside, is provided directly behind the external circulation fan coil unit. A right-hand electric valve is installed on the external circulation fan coil unit window to allow or close communication with the outside. An external circulation fan is fixedly connected to the middle of the front end face of the external circulation fan coil unit, and the air outlet of the external circulation fan is connected to an external circulation four-way valve. Electric air valves are installed on the three small branch pipes of the external circulation four-way valve, and the air outlet of the external circulation four-way valve is connected to... There is an external circulation fabric duct, which is vertically suspended in the planting greenhouse. The external circulation fabric duct is conical. The fan outlet, four-way main outlet, large, medium and small branch pipe diameters, electric air valve, and fabric duct of the external circulation fan coil unit are all the same size as the diameters of the large, medium and small internal circulation components. This design is mainly to ensure that the air pressure is equal when the nine fabric ducts are inlet. The area of ​​the external circulation fan coil unit is half that of the internal circulation fan coil unit, and the external circulation fan coil unit is surrounded by thick iron sheets, leaving only the back to connect with the external window.

[0006] Preferably, an internal circulation cooling water pipe is connected to the bottom of the pair of internal circulation fan coil units, and the bottom end of the internal circulation cooling water pipe passes through the planting greenhouse and is connected to an internal circulation cooling and heat preservation water tank controlled by a variable frequency water source heat pump.

[0007] Preferably, an external circulating cooling water tank is installed on the outside of the planting greenhouse, and an external circulating cooling water pipe is connected to the external circulating cooling water tank. The external circulating cooling water pipe passes through the planting greenhouse and is connected to the external circulating fan coil unit. The volume of the external circulating cooling water tank can be set to half that of the internal circulating cooling and heat preservation water tank controlled by the variable frequency water-source heat pump. Two heat preservation water tanks are set up. The purpose is to reduce the water temperature of the internal circulating fan coil unit separately under extreme high temperature and high humidity weather conditions, thereby avoiding excessive cooling load on the external circulating fan coil unit due to weather factors.

[0008] Preferably, a centrifugal fan with a built-in water mist delivery system is installed at the central front end of the connection between the internal circulation fan coil unit and the external circulation fan coil unit. The air outlet of the centrifugal fan with a built-in water mist delivery system is connected to a PVC humidification pipe, which extends straight to the rear end of the greenhouse, parallel to the horizontal line of the greenhouse floor. A variable frequency humidifier is installed at the bottom of the greenhouse, and there is a connecting pipe between the variable frequency humidifier and the centrifugal fan with a built-in water mist delivery system. The variable frequency humidifier can humidify the greenhouse, and the humidified air is discharged through the centrifugal fan with a built-in water mist delivery system, the connecting pipe, and the PVC humidification pipe, thereby ensuring the humidity inside the greenhouse.

[0009] Preferably, a temperature and humidity sensor is suspended at the bottom of each pair of internal circulation fan coil units, and a carbon dioxide sensor is suspended in the middle of the bottom of the external circulation fan coil unit; the humidity and carbon dioxide concentration in the planting greenhouse can be monitored in real time through the humidity sensor and the carbon dioxide sensor.

[0010] Preferably, a wind baffle is fixed to the outer wall of the internal circulation fan coil unit, and a 10-centimeter space is left between the wind baffle and the inner wall of the planting greenhouse. A perforated guide plate is fixed to the middle of the inner side of a pair of wind baffles.

[0011] Preferably, the three small branches of the right inner circulation four-way, left inner circulation four-way, and outer circulation four-way are all designed with large, medium, and small diameters.

[0012] Preferably, both the internal circulation fan and the external circulation fan are set to three speeds: large, medium, and small.

The lower end face and both sides of the external circulation fabric duct are machined with a number of small round holes that are equally distributed and the same size. The two side walls of the PVC humidification pipe are machined with a number of small round holes that are equally distributed and the same size. The diameter of the small round holes in the external circulation fabric duct is half the diameter of the small round holes in the right inner circulation fabric duct and the left inner circulation fabric duct.

[0014] Beneficial effects This invention provides a low-carbon integrated environmental control system for the fruiting period of aerobic edible fungi, which has the following beneficial effects: This system effectively solves the problems of poor quality and high energy consumption in the production of aerobic edible fungi from existing environmental control equipment. On the one hand, through the rational design of the internal and external circulation refrigeration mechanisms, the temperature inside the greenhouse can be precisely controlled. The internal circulation refrigeration mechanism utilizes internal circulation fan coil units, internal circulation fans, four-way valves, and fabric ducts to improve the airflow. Furthermore, the internal circulation cooling water pipes are connected to the internal circulation refrigeration and insulation water tank controlled by the variable frequency water-source heat pump, which can precisely adjust the water temperature and create a suitable temperature environment for the growth of edible fungi. The external circulation refrigeration mechanism, including external circulation fan coil units, external circulation fans, external circulation four-way valves, and external circulation fabric ducts, works in conjunction with the internal circulation mechanism to flexibly adjust the temperature under different climatic conditions. The external circulation refrigeration water tank also prevents the external circulation fan coil units from being overloaded. On the other hand, the system also performs excellently in regulating humidity and carbon dioxide concentration. The combination of the PVC pipe for humidification, the centrifugal fan for delivering water mist, the PVC humidification pipe, and the frequency converter humidifier can accurately control the humidity in the greenhouse based on real-time monitoring data from the humidity sensor. The carbon dioxide sensor provides real-time feedback on the carbon dioxide concentration in the mushroom area, providing a basis for adjusting ventilation and other operations, and ensuring a stable growth environment for edible fungi. Meanwhile, the three-part pipe design with large, medium, and small diameters for the right internal circulation four-way, left internal circulation four-way, and external circulation four-way, as well as the large, medium, and small settings for the internal and external circulation fans, can be flexibly adjusted according to actual needs, further reducing energy consumption. Moreover, the design of the perforated guide plate and the inlet, outlet, return, and exhaust of the internal and external circulation fans and exhaust fans ensures uniform gas diffusion and circulation, improving energy utilization efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-3 The present invention provides a technical solution: a low-carbon integrated environmental control system for the fruiting period of aerobic edible fungi, including a planting greenhouse 1, wherein several exhaust fans 2 are evenly arranged at the lower ends of both sides of the planting greenhouse 1, and the exhaust fans 2 are equipped with check valves to prevent backflow of strong winds from the outside, and electric valves are provided on the inside to open or close. The planting greenhouse 1 is equipped with an internal circulation refrigeration mechanism and an external circulation refrigeration mechanism. The internal circulation refrigeration mechanism includes an internal circulation fan coil unit 3 fixedly connected to the upper part of the planting greenhouse 1. A pair of internal circulation fans 4 are fixedly connected to the front end face of the internal circulation fan coil unit 3. The air outlets of the left and right internal circulation fans 4 are respectively connected to a right internal circulation four-way 5 and a left internal circulation four-way 6. Electric air valves are installed on the three small branches of the right internal circulation four-way 5 and the left internal circulation four-way 6. The air outlets of the small branches of the right internal circulation four-way 5 and the left internal circulation four-way 6 are respectively connected to a right internal circulation fabric distribution duct 7 and a left internal circulation fabric distribution duct 8. The right internal circulation fabric distribution duct 7 and the left internal circulation fabric distribution duct 8 are horizontally aligned with the planting greenhouse 1. The right internal circulation fabric distribution duct 7 and the left internal circulation fabric distribution duct 8 are both conical. The exhaust fan 2 is set to three speeds: high, medium, and low. The total exhaust volume of the six exhaust fans 2 at each speed is slightly less than the fresh air volume generated by the external circulation fan 11 at each speed. This is to ensure that the planting greenhouse 1 is always kept under a slight positive pressure during equipment operation. There is fast-flowing cold water in the internal circulation fan coil 3. The temperature of the cold water is controlled by the variable frequency ground source heat pump outside the planting greenhouse 1 and the circulating water structure on the internal circulation cooling and insulation water tank 14. At the same time, the right internal circulation fabric duct 7 and the left internal circulation fabric duct 8 are both conical.

[0021] In this embodiment, the external circulation refrigeration mechanism includes an external circulation fan coil unit 9 fixedly connected to the middle of the bottom end of the internal circulation fan coil unit 3. An external circulation fan coil unit window 22 connected to the outside is provided directly behind the external circulation fan coil unit 9, and an electric valve is installed on the external circulation fan coil unit window 22 for connecting or closing to the outside. An external circulation fan 10 is fixedly connected to the middle of the front end face of the external circulation fan coil unit 9, and the air outlet of the external circulation fan 10 is connected to an external circulation four-way valve 12. Electric air valves are installed on the three small branches of the external circulation four-way valve 12. An external circulation fabric duct 13 is connected to the air outlet of the external circulation four-way valve 12, and the external circulation fabric duct 13 is vertically suspended in the planting greenhouse 1. The external circulation fabric duct 13 is conical. The fan outlet, four-way main outlet, large, medium and small branch pipe diameters, electric air valves, and fabric air ducts of the external circulation fan coil unit 9 are all the same size as the diameters of the large, medium and small internal circulation components. This design is mainly to ensure that the air pressure is equal when multiple fabric air ducts are inlet. The area of ​​the external circulation fan coil unit 9 is half that of the internal circulation fan coil unit 3, and the external circulation fan coil unit 9 is surrounded by thick iron sheets, with only the back connected to the external window 22.

[0022] In this embodiment, the bottom of the pair of internal circulation fan coil units 3 is connected to an internal circulation cooling water pipe 18, and the bottom end of the internal circulation cooling water pipe 18 passes through the planting greenhouse 1 and is connected to a variable frequency water source heat pump controlled internal circulation cooling and heat preservation water tank 14.

[0023] In this embodiment, an external circulation cooling water tank 15 is provided on the outside of the planting greenhouse 1. An external circulation cooling water pipe 17 is connected to the external circulation cooling water tank 15. The external circulation cooling water pipe 17 passes through the planting greenhouse 1 and is connected to the external circulation fan coil unit 9. The volume of the external circulation cooling water tank 15 can be set to half that of the internal circulation cooling insulation water tank 14 controlled by the variable frequency water source heat pump. Two insulation water tanks are set up so that the water temperature of the internal circulation fan coil unit 3 can be reduced separately under extreme high temperature and high humidity weather conditions, thereby avoiding excessive cooling load on the external circulation fan coil unit 9 due to weather factors.

[0024] In this embodiment, the internal circulation fan coil unit 3 and the external circulation fan coil unit 9 are connected by a centrifugal fan 19 with a built-in water mist delivery PVC pipe. The air outlet of the centrifugal fan 19 with a built-in water mist delivery PVC pipe is connected to a PVC humidification pipe 11. The right end of the PVC humidification pipe 11 extends straight to the rear end of the greenhouse, parallel to the horizontal line of the ground of the planting greenhouse 1. A variable frequency humidifier 20 is installed at the bottom inside the planting greenhouse 1. There is a connecting pipe 21 between the variable frequency humidifier 20 and the centrifugal fan 19 with a built-in water mist delivery PVC pipe. The variable frequency humidifier 20 can humidify, and then the humidified gas is discharged through the built-in water mist centrifugal fan 19 in the humidification PVC pipe, in conjunction with the connecting pipe 21 and the PVC humidification pipe 11, thereby ensuring the humidity inside the planting greenhouse 1.

[0025] In this embodiment, a temperature and humidity sensor 16 is suspended at the bottom of each pair of internal circulation fan coil units 3, and a carbon dioxide sensor 23 is suspended in the middle of the bottom of the external circulation fan coil unit 9. The humidity and carbon dioxide concentration inside the planting greenhouse 1 can be monitored in real time using humidity sensor 16 and carbon dioxide sensor 23.

[0026] In this embodiment, the outer wall of the internal circulation fan coil unit 3 is fixedly connected to a wind baffle 25, and the wind baffle 25 and the inner wall of the planting greenhouse 1 are left with a space of 10 cm. A perforated guide plate 24 is fixedly connected to the middle of the inner side of a pair of wind baffles 25.

[0027] In this embodiment, the three small branch pipes of the right inner circulation four-way 5, the left inner circulation four-way 6, and the outer circulation four-way 12 are designed with large, medium, and small diameters, respectively. Three electric air valves with matching diameters are installed at their outlets. Then, according to the outer walls of the large, medium, and small branch pipes, fabric air pipes with matching diameters are tightly fitted. The inner circulation air pipes are arranged horizontally from the inside to the outside and suspended on the roof of the greenhouse according to the large, medium, and small diameters. The outer circulation air pipes are arranged vertically according to the large, medium, and small diameters and suspended, extending straight along the roof to the rear end of the planting greenhouse 1.

[0028] In this embodiment, both the internal circulation fan 4 and the external circulation fan 11 are configured with three speeds: large, medium, and small.

[0029] In this embodiment, the lower end face and both sides of the right inner circulation fabric duct 7 and the left inner circulation fabric duct 8 are each machined with a number of small round holes that are equally distributed and the same size. The lower end face and both sides of the external circulation fabric duct 13 are each machined with a number of small round holes that are equally distributed and the same size. The two side walls of the PVC humidification pipe 11 are each machined with a number of small round holes that are equally distributed and the same size. The diameter of the small round holes in the external circulation fabric duct 13 is half the diameter of the small round holes in the right inner circulation fabric duct 7 and the left inner circulation fabric duct 8. The ten ducts mentioned above—the right inner circulation fabric duct 7, the left inner circulation fabric duct 8, the PVC humidification pipe 11, and the outer circulation fabric duct 13—are suspended vertically from their respective heights, parallel to the horizontal line of the ground, to the rear end of the greenhouse. Several small, identical holes are drilled at appropriate angles and in a straight line at appropriate intervals on the lower surfaces of the right inner circulation fabric duct 7 and the left inner circulation fabric duct 8. Several small, equally sized holes are drilled at appropriate angles and in a straight line on the left and right sides of the outer circulation fabric duct 3, at appropriate angles and in a straight line, corresponding to half the diameter of the small holes in the right inner circulation fabric duct 7 and the left inner circulation fabric duct 8. The airflow exiting from the small holes in the inner circulation fabric duct 7 and the left inner circulation fabric duct 8 intersects perpendicularly with the airflow exiting from the small holes in the outer circulation fabric duct 13. The lower left and right sides of the PVC humidification pipe 11 are at appropriate angles... Drill several small round holes of the same size (with appropriate diameter) at equal intervals in a straight line. The small round holes on the right inner circulation fabric duct 7, the left inner circulation fabric duct 8, the PVC humidification pipe 11, and the outer circulation fabric duct 13 are also equidistant. In this way, the mist and water air discharged from the small round holes of the PVC humidification pipe will also accurately converge at the above-mentioned vertical convergence point. Since the wind pressure of the 10 ducts is equal in any working state, the airflow speed discharged from the small round holes is also consistent. Therefore, the convergence point of the airflow discharged from all the small round holes is located in a space of equal height and width (left and right) above the mushroom growing area in the greenhouse. Due to the momentum combination effect, the three different airflows form a stable mixed air as soon as they diffuse into the mushroom growing area. This temperature and humidity is the optimal temperature and humidity set for the mushroom growing area.

[0030] It is worth noting that all standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The models of electrical structures and equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. Furthermore, the circuit connections adopt conventional connection methods in the prior art. The supporting electrical structures for control, current detection, position feedback, predicted voltage synchronization, and parameter adjustment of the electrical equipment are all existing technologies, such as PLC controllers and module structures, and therefore will not be described in detail here. All content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0031] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0032] Example: The combination of operation and shutdown of all internal and external circulation and exhaust fan 2 equipment units is as follows: Group A: 1. Switches for 4 main speeds of internal circulation fan; 2. Switches for 22 electric valves on the outer window of external circulation fan coil unit; 3. Main switch for all speeds of external circulation fan 10; 4. Switches for the inner electric valve of exhaust fan 2 and the main switch for all speeds of that fan; 5. Switches for large, medium and small electric air valves of all 3-point pipes with oblique four-way valves. This combination is used during the budding stage. The operating status is as follows: 1 is operated at the high setting, 2 and 4 electric valves are closed, 3 and 4 main switches are disconnected, 5 internal circulation two electric large air valves are open, and the rest are closed.

[0033] Group B: 1. External circulation fan 10-speed switch, 2. Internal circulation fan 4-speed switch, 3. Exhaust fan 2-speed switch and inner electric valve switch, 4. All 3-point pipe electric valve switches for the oblique four-way valves, 5. External circulation fan coil unit external window 22 electric valve switch. This combination is used during the young mushroom stage. The operating status is as follows: 1, 2, and 3 are operated at the low setting, the electric valve of 3 is open, the three electric small air valves of the internal and external circulation of 4 are open, and the rest are closed, and the valve of 5 is open.

[0034] Group C: 1. Medium speed switch for external circulation fan 10, 2. Medium speed switch for internal circulation fan 4, 3. Medium speed switch for exhaust fan 2 and inner electric valve switch, 4. Electric air valve switches for all 3-point pipes of the oblique four-way valves (large, medium and small), 5. Electric valve switch for external circulation fan coil unit outer window 22. This combination is used during the mid-season mushroom cultivation. The operating status is as follows: 1, 2, and 3 are operated at medium speed, the electric valve of 3 is open, the three electric medium-speed valves of 4 for internal and external circulation are open and the rest are closed, and the valve of 5 is open.

[0035] Group D: 1. External circulation fan 10-speed switch, 2. Internal circulation fan 5-speed switch, 3. Exhaust fan 2-speed switch and inner electric valve switch, 4. All 3-point pipe electric valve switches for all oblique four-way valves, 5. External circulation fan coil unit external window 22 electric valve switch. This combination is used during the mushroom growing season. The operating status is as follows: 1, 2, and 3 are operated at the highest setting, the electric valve of 3 is open, the three electric large air valves of the internal and external circulation of 4 are open and the rest are closed, and the valve of 5 is open. The relationships between the combinations A, B, C, and D above are as follows: 1. When combination A is running, combinations B, C, and D are stopped; 2. When combination B is running, combinations A, C, and D will stop. 3. Combination C runs, while combinations A, B, and D stop. 4. When combination D is running, combinations A, B, and C stop. In addition to the four combinations A, B, C, and D, in production practice, one or two additional special application combinations such as D or E can be added, which will not be elaborated here.

[0036] The internal switches of the above-mentioned combined equipment units are replaced with a unified wireless receiver, which controls the operation and shutdown of the combination of A, B, C, and D according to the optimal carbon dioxide concentration commands set by the carbon dioxide concentration sensors suspended in the fruiting area for different growth stages of the aerobic edible fungi during the fruiting period, corresponding to the different growth stages of the fruiting bodies.

[0037] In addition, the temperature sensor of the initial stable temperature and humidity zone of the three mixed air streams suspended above the mushroom growing area has a unified command receiving relationship with the variable frequency water source heat pump unit, while the humidity sensor has a unified command receiving relationship with the variable frequency humidifier. Then, all of these wireless receivers are integrated into the same outdoor electronic panel for operation, which enables better low-carbon integrated environmental control cultivation of aerobic edible fungi during the fruiting period.

[0038] When the above-mentioned combination of B, C, and D is in operation, the cold air discharged downward from the small round holes of the left and right inner circulation fabric air ducts, the pre-cooled fresh air discharged to the left and right from the small round holes of the outer circulation fabric air duct 13, and the misty air discharged from the PVC humidification pipe 11 converge. In this way, the three airflows mix and diffuse towards the mushroom growing area at the lower left and right, forming a stable temperature and humidity. This temperature and humidity can be set according to different growth stages of aerobic edible fungi fruiting bodies, and the temperature and humidity sensors suspended on the upper left and right sides of the mushroom growing area instruct the variable frequency water source heat pump to control the water temperature controlled by the inner circulation cooling and heat preservation water tank, so as to achieve precise control of temperature and humidity at the set value.

[0039] The operation and shutdown of the combination of A, B, C, and D, controlled by the carbon dioxide sensors suspended in the mushroom growing area, satisfies the oxygen consumption of aerobic edible fungi fruiting bodies at different growth stages due to metabolism in the target environment (within cultivation greenhouse 1). The large amount of carbon dioxide gas generated during the operation of the combination of B, C, and D is promptly discharged. In addition, the slight positive pressure inside the greenhouse ensures that the aerobic edible fungi fruiting bodies at different growth stages, from young mushrooms to medium-sized mushrooms to large mushrooms, achieve the most suitable carbon dioxide concentration when the combination of B, C, and D is in operation. This makes the air inside cultivation greenhouse 1 close to that of fresh air in nature.

[0040] Depend on Figure 3As shown, denser carbon dioxide gas is discharged from the left and right exhaust fans 2. Additionally, due to the obstruction of the wind deflector 25 by the three airflows and their converging momentum-combined airflow, the rising, slightly warmer airflow mainly enters the internal circulation cooling fan coil unit 3 along the internal circulation cooling return air path for cooling. Meanwhile, the air inlet path of the PVC humidifier pipe 11 is also mainly located at the slightly warmer top of the planting greenhouse 1. Thus, the target environment (within the planting greenhouse 1) forms a situation where carbon dioxide sinks and is promptly discharged by the exhaust fans 2, hot air rises and is promptly cooled by the internal circulation cooling system, and pre-cooled fresh air (external circulation cooling) continuously supplies oxygen, creating a... With a slight positive pressure, when any combination of B, C, and D is running, the three airflows—the internal circulation cooling return air, the PVC pipe air inlet air, and the airflow discharged from the small round holes on the internal and external circulation fabric air ducts and PVC humidification pipe 11—converge and their momentum combines to diffuse towards the fruiting area. The airflow discharged outward by the exhaust fans 2 at the lower ends of both sides of the planting greenhouse 1 also flows towards its respective target with minimal interference or disturbance, following its own path and direction. This cycle repeats continuously, forming an efficient, energy-saving, scientific, and reasonable airflow circulation. Thus, an optimal spatial environment for different growth stages of aerobic edible fungi fruiting bodies during the fruiting period is created through a sophisticated airflow organization design.

[0041] The unique airflow organization design mentioned above is the core difference from traditional environmental control equipment. Because aerobic edible fungi are very sensitive to carbon dioxide concentration during the fruiting period from young mushrooms to medium-sized mushrooms to large mushrooms, and the airflow organization of traditional environmental control equipment is very easy to accumulate carbon dioxide gas, this causes the carbon dioxide sensor inside to frequently activate its ventilation equipment, which in turn causes frequent fluctuations in temperature and humidity, making it difficult to create the optimal growth environment for edible fungi during the fruiting period.

[0042] Since the constant temperature layer below the surface in most parts of central and eastern my country is 10 to 20 degrees Celsius, and the optimal growth temperature of most aerobic edible fungi during the fruiting period is within this range, when the A, B, C, and D combinations are running, the compressor of the variable frequency water-source heat pump controlling the internal circulation cooling and insulation water tank 14 does not need to work or runs at a low frequency to maintain the stability of the set cold water temperature in the internal and external circulation coils. In addition, if the aerobic edible fungi require a lower suitable temperature during the fruiting period (such as morels), a dehumidification method can be added to the window 22 of the external circulation cooling coil to reduce the dew point temperature of the air outside the shed (entering the external circulation fan coil 9), thereby reducing its cooling load. Cold energy recovery equipment can also be installed at the exhaust port, which will not be elaborated here. In this way, the optimal temperature set in the target environment (inside the planting shed 1) can be maintained stably with low energy consumption.

[0043] Since the cooling load is the superposition of latent heat exchange and sensible heat exchange, while the heating load is only sensible heat exchange, when heating is applied in the target environment (inside greenhouse 1), the heat generated by the metabolism of the mushroom bags and fruiting bodies in the greenhouse is added. The greenhouse only needs to turn on the humidification system according to the humidity sensor to meet the optimal environment for different growth stages of aerobic edible mushroom fruiting bodies under low temperature weather conditions. This will not be elaborated further here.

[0044] Since there is no contradiction or constraint between light and environmental factors such as temperature, humidity, and carbon dioxide concentration, it will not be discussed further here.

[0045] In engineering practice, the installation location, configuration size, and combination method of all equipment units inside and outside the greenhouse can be calculated based on the condition of the greenhouse, the number of mushroom spawn bags, and weather factors to determine the required power, size, quantity, and model of the equipment units.

[0046] The optimal environmental factors required for different growth stages of the fruiting bodies of the above aerobic edible fungi during the fruiting period can be truly realized under the control of variable frequency water source heat pumps, achieving low-carbon integrated environmental control.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
