Abstract
Description
Technical Field
[0001] This invention relates to the field of planting device technology, specifically to a planting cavity system and planting method with integrated airflow control function, and more particularly to a planting cavity system and planting method with integrated panel air outlet, substrate air compression and closed-loop waste discharge functions. Background Technology
[0002] In modern indoor agriculture, especially in high-density plant factories, controlling the plant's growth environment is crucial to ensuring yield and quality. However, existing cultivation techniques still have several technical challenges that are difficult to address systematically.
[0003] Firstly, regarding the root environment of plants, in traditional planting methods, the entry of oxygen and the expulsion of carbon dioxide into the roots mainly occur through dissolved oxygen in the water and gas diffusion. When the substrate has poor aeration or the oxygen content in the root nutrient solution is low, it will not only cause root hypoxia and suffocation, but also cause waste gases such as carbon dioxide produced by root respiration to accumulate at the bottom of the substrate. This anaerobic environment easily induces the proliferation of anaerobic microorganisms such as Pythium, ultimately leading to root rot and severely inhibiting the plant's normal absorption of nutrients.
[0004] Secondly, regarding the canopy environment, when plants enter the canopy-closing stage, the densely packed, intertwined leaves severely obstruct natural airflow. This forms a static, high-humidity air "boundary layer" on the leaf surface and at the base of the plant. Even if wind blows from the top or sides, it is difficult for the wind to reach the underside due to the intertwined leaves. This boundary layer, on the one hand, hinders the effective supply of fresh carbon dioxide to the leaf surface, thus affecting the plant's photosynthetic efficiency; on the other hand, the high humidity environment also hinders transpiration, affecting the effective transport of nutrients such as calcium carried by water, making it highly susceptible to physiological diseases such as "heartburn" and providing a breeding ground for fungal diseases such as gray mold and downy mildew. Summary of the Invention

It is connected to the main body of the implantation cavity through an air inlet branch pipe. The centrifugal fan is installed in the air inlet pipe to guide the gas from the air inlet end to the air outlet end.
[0015] Preferably, the implantation cavity body includes multiple implantation cavity bodies, and the multiple implantation cavity bodies are stacked, with different layers of implantation cavity bodies respectively connected to different layers of air intake branch pipes; The air outlet of the air intake pipe extends upward, thereby connecting sequentially with the air intake branch pipes of different layers. The diameter of the pipe at the connection point between the air outlet and the air intake branch pipes of different layers decreases sequentially from bottom to top.
[0016] Preferably, the valve includes a normally closed solenoid valve.
[0017] Preferably, it also includes a waste liquid evaporation system, located inside the waste liquid tank, for evaporating the collected waste liquid.
[0018] Preferably, the waste liquid evaporation system includes an ultrasonic atomizer, a heating element, or a fan.
[0019] Preferably, it also includes a controller and sensors; The controller is electrically connected to the sensor and the centrifugal fan of the air intake system, and is used to adaptively control the opening and closing of the centrifugal fan based on the feedback signal of the sensor.

[0021] The implantation method of the implantation cavity system with integrated airflow regulation function provided by the present invention specifically includes the following steps: The air intake system pressurizes gas into the implantation chamber body, wherein the bottom of the cup in the implantation chamber body is provided with a waste discharge hole that is connected to the waste liquid tank through a waste discharge pipe; The waste discharge pipeline is equipped with a controllable valve, the waste liquid tank is equipped with a waste liquid evaporation system, and the internal structure of the planting chamber is configured such that: a part of the gas is pressed into the substrate for plant growth through the second vent, and another part of the gas is blown toward the plant canopy through the first vent.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention systematically solves the root and leaf environment problems. Through an integrated dual airflow design, the second stomata compresses the substrate, actively supplying oxygen to the plant roots and expelling waste gas produced by root respiration. Since the temperature of the compressed gas is controllable, the temperature of the plant roots can be adjusted within a suitable range, fundamentally avoiding root rot caused by substrate hypoxia. At the same time, the first stomata blows air into the plant canopy, effectively breaking the high-humidity static boundary layer on the leaf surface, promoting gas exchange inside and outside the canopy and plant transpiration, thereby effectively preventing the occurrence of heartburn and fungal diseases. The active air supply to the roots and the gentle breeze disturbance on the leaf surface work together to greatly promote the transport of water and nutrients in the plant, comprehensively improving the plant's health and growth efficiency.
[0026] 2. This invention achieves zero discharge of waste liquid and physical blocking of diseases. Through a closed-loop waste liquid treatment mode of "collection-isolation-evaporation", the nutrient waste liquid generated during the planting process is collected and evaporated, which completely avoids the pollution caused by the direct discharge of nutrient waste liquid to the environment. Furthermore, by setting controllable valves on the waste discharge pipeline for physical isolation and evaporating the waste liquid in the waste liquid tank, pathogens that may be carried in the waste liquid can be effectively killed, fundamentally blocking the path of disease transmission in the planting system through waste liquid circulation, and significantly improving the biosafety of the entire planting system.
[0027] 3. The present invention has a high degree of structural integration and ingenious design. By cleverly integrating the plant support structure, the pressure chamber forming a dual airflow channel and the controlled waste discharge function into a single planting cavity, the system has a compact structure and powerful functions. While achieving integrated and precise control of the microenvironment of plant roots and leaves, it also solves the problem of waste liquid treatment and realizes efficient integrated design.

Figure 5 This is a half-sectional schematic diagram of the implant cavity body from a side view angle in one embodiment of the present invention; Figure 6This is a half-sectional schematic diagram of the implant cavity body from a side view angle in another embodiment of the present invention.
[0029] The diagram shows: Detailed Implementation
[0030] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0031] Example 1 In one embodiment of the present invention, a basic implementation scheme for a planting chamber system integrating dual airflow and closed-loop waste discharge is provided. This system, through a highly integrated approach, collaboratively achieves active compressed air supply to the plant root zone, micro-wind disturbance of the canopy, precise control of root zone temperature, and zero-discharge treatment of waste liquid.
[0032] like Figure 1 The diagram shown is a schematic representation of the overall structure of the implantation cavity body 1 in this embodiment. The system mainly includes the implantation cavity body 1, a waste drainage system, and a waste liquid treatment device. As an optional implementation, the system also includes an intake air temperature control unit located in the intake system. Specifically, the implant chamber body 1, as the core load-bearing structure of the entire system, is internally constructed as an airtight pressure chamber. The implant chamber body 1 can be integrally molded from food-grade engineering plastics (such as ABS or PP) or corrosion-resistant, easy-to-clean materials such as stainless steel through processes such as injection molding or welding to ensure its structural strength and airtightness. An air inlet 13 is provided on the side wall of the implant chamber body 1, which is connected to an air intake system (such as an air pump or centrifugal fan) to pressurize gas into the implant chamber body 1.
[0033] The top surface of the planting chamber body 1 is a planting panel with several planting holes evenly distributed on it, and a support cup 11 is placed in each planting hole. The support cup 11 is a container for holding the plant growth substrate. In this embodiment, the plant, along with the capsule substrate required for its growth, is placed together in the support cup 11. It is understood that the capsule substrate may include, but is not limited to, materials with good air permeability and water retention, such as rock wool, coconut coir, peat moss, or sponge.
[0034] A key feature of this embodiment is that it utilizes the internal structure of the implant cavity body 1 to form at least two airflow channels with different functions. The following will combine... Figure 6The formation path of the dual airflow is explained in the figure, which is a partial cross-sectional schematic diagram of the implant cavity body 1, clearly revealing the formation path of the dual airflow.
[0035] The first airflow channel is used to direct gas to the surface of the planting panel to aerate the plant canopy. In this embodiment, the channel is specifically composed of at least one first vent 12 disposed on the planting panel and distributed around the edge of each cup 11. When a positive pressure is formed inside the planting chamber 1, some gas is blown upward from these first vent 12, forming one or more breezes that directly act on the base of the plant canopy. This upward airflow can effectively break the static, high-humidity air "boundary layer" formed between dense leaves. On the one hand, it promotes air exchange between the inside and outside of the canopy, supplementing the leaves with fresh carbon dioxide for photosynthesis; on the other hand, it accelerates the evaporation of water from the leaf surface, promoting transpiration. It is understood that vigorous transpiration is the main driving force for the upward transport of water and nutrients (especially poorly mobile calcium) in plants. Therefore, this design can effectively prevent physiological diseases such as "heartburn" caused by obstructed calcium transport. At the same time, keeping the leaf surface dry also greatly inhibits the conditions for the occurrence of fungal diseases such as gray mold and downy mildew.
[0036] The second airflow channel is used to guide and pressurize the gas into the substrate for plant growth. In this embodiment, the channel is specifically composed of at least one second air hole 16 located at the bottom of the cup 11. When the gas source is activated, the gas is pressed in from the air inlet 13 and fills the entire planting chamber body 1, creating positive pressure inside. Correspondingly, under this pressure gradient, another portion of the gas is forced through the capsule substrate from bottom to top through the second air hole 16 at the bottom of the cup 11. This process can actively transport oxygen-rich air to the area where the plant roots are located, while simultaneously expelling waste gases such as carbon dioxide and ethylene produced by root respiration from the substrate. The expelled carbon dioxide can also be supplied to the leaves as nutrients. It should be noted that experimental data shows that when the oxygen concentration in the substrate drops below 5%, anaerobic microorganisms will rapidly multiply and cause root rot. The substrate pressurization scheme provided in this embodiment can ensure that the oxygen concentration in the root zone is always maintained at a healthy level, thereby fundamentally preventing the occurrence of root rot.
[0037] like Figure 3As shown, the waste drainage system of this embodiment includes a waste drainage port 14 located on the side of the implantation cavity body 1, a waste drainage hole 15 located at the bottom of the cup 11, a waste drainage branch pipe 17 connecting the waste drainage hole 15 and the waste drainage port 14, a waste drainage pipeline 8 connected to the waste drainage port 14, and a waste liquid tank 10 for receiving waste liquid. To ensure that the waste liquid accumulated in the cavity can be completely drained by gravity, the waste drainage port 14 is preferably located at the lowest point of the end of the waste drainage branch pipe 17. The waste drainage pipeline 8 allows fluid communication between the implantation cavity body 1 and the waste liquid tank 1 located below it.
[0038] In a preferred embodiment, no waste drain branch pipe 17 is provided inside the implantation cavity body 1, and the waste drain port 14 is directly provided at the bottom of the entire implantation cavity body 1. The waste liquid at the bottom of each cup 11 is naturally dripped into the bottom of the implantation cavity body 1 under the action of gravity, and discharged into the waste drain pipe 8 through the waste drain port 14 left at the bottom. In order to ensure that the waste liquid can be emptied by gravity, the bottom of the implantation cavity body 1 is configured to be horizontal or inclined downward toward the waste drain port 14.
[0039] A controllable valve 9 is installed on the waste discharge pipeline 8 to control the connection and disconnection between the implant chamber body 1 and the waste liquid tank 10. As a preferred implementation, this controllable valve 9 can be a normally closed solenoid valve. It should be noted that the normally closed characteristic (i.e., the valve is closed in the normal state when not energized) ensures that the implant chamber body 1 can maintain an airtight seal to establish effective working pressure when performing the compressed air / blowing function. The controller only energizes the solenoid valve to open it when waste discharge is required. This design not only achieves automated control of the waste discharge process, but more importantly, through the isolation of the physical valve, it can completely block the possibility of pathogens in the waste liquid tank 10 flowing back through the pipeline or entering the implant chamber body 1 in the form of aerosols, thereby significantly improving the biosafety of the system.
[0040] Waste liquid tank 10 is used to collect waste liquid containing residual nutrients discharged from the main body 1 of the planting chamber. To achieve closed-loop treatment and zero discharge of waste liquid, a waste liquid evaporation system is installed inside the waste liquid tank 10. In this embodiment, the waste liquid evaporation system is specifically a heating evaporation system, for example, composed of heating elements such as heating wires, heating tubes, or positive temperature coefficient thermistors. When the waste liquid tank 10 collects a certain amount of waste liquid, the controller starts the heating evaporation system to heat the waste liquid to boiling and evaporate it. In another embodiment, considering power consumption and efficiency, the waste liquid evaporation system can also use a fan, which directly acts on the waste liquid to evaporate it. The generated water vapor can be discharged into the indoor environment through the vent at the top of the waste liquid tank 10 (for humidification) or collected and treated uniformly through pipes, while the mineral salts in the waste liquid remain in solid form in the waste liquid tank 10, which can be cleaned periodically and recycled as solid fertilizer.
[0041] To further optimize the plant's growth environment, especially in controlling the root zone temperature, this embodiment preferably also includes an inlet temperature control unit. For example... Figure 2 As shown, the air intake temperature control unit is installed in the air intake pipe 2 of the air intake system to regulate the temperature of the gas entering the main body 1 of the planting chamber. Specifically, the air intake temperature control unit may include an energy storage tank 6, which has a heat exchange structure inside, such as a coil-type heat exchange plate 4. Water is pumped from inside the energy storage tank 6 to the heat exchange plate 4, and after flowing through the heat exchange plate 4, the water flows back into the energy storage tank 6. The gas drawn from the air intake end 5 of the air intake pipe 2 exchanges heat with the heat exchange plate 4 as it flows through it. In this embodiment, the energy storage tank 6 is also equipped with an active cooling system or heating system to precisely regulate and stabilize the water temperature within an optimal range. Research and experimental data show that stabilizing the root zone temperature within the range of 20-25℃ (especially around 22℃) has a significant effect on increasing yield and improving quality for most crops. This is because the root system has the highest absorption efficiency for key nutrients such as phosphorus and potassium within this temperature range, and the dissolved oxygen content in the water is also at a high level. Furthermore, maintaining the temperature at 22°C can effectively inhibit the activity of various pathogens, such as Pythium, that prefer high-temperature environments (e.g., above 28°C). Therefore, pre-regulating the air temperature entering the substrate to 22°C through the air intake temperature control unit is one of the key measures to achieve optimal microenvironment control in the root zone.
[0042] Furthermore, in this embodiment, the implantation cavity body 1 can be multiple stacked, with different layers of implantation cavity bodies 1 respectively connected to different layers of air inlet branch pipes 7. Correspondingly, the air outlet end of the air inlet pipe 2 extends upward, thereby connecting sequentially with the air inlet branch pipes 7 of different layers. The diameter of the pipe at the connection point between the air outlet end and the air inlet branch pipes 7 of different layers decreases sequentially from bottom to top, thereby ensuring that during the blowing / compressing stage, the gas can be pumped to each layer of implantation cavity body 1 at the same pressure.
[0043] The following is a detailed description of a planting method that integrates dual airflow and closed-loop waste discharge, as provided in this embodiment.
[0044] A complete work cycle can be automatically executed by a controller (such as a microcontroller, programmable logic controller, or industrial computer) according to a preset program.
[0045] First, the system enters the air compression / blowing phase. The cycle starts. The controller first issues a command to ensure the normally closed solenoid valve is de-energized and closed to guarantee the airtightness of the planting chamber body 1. Then, the controller starts the centrifugal fan 3 to pressurize the planting chamber body 1 with air regulated by the inlet temperature control unit. The pressure inside the chamber quickly builds up, and dual airflow (i.e., substrate compression and panel blowing) occurs simultaneously. This phase lasts for a preset time, such as 5 minutes, controlled by a timer or delay program. It should be noted that this duration can be adjusted according to factors such as plant size, planting density, and ambient temperature and humidity. After the timer expires, the controller stops the centrifugal fan 3.
[0046] Next, the system enters the waste discharge judgment and execution phase. The compressed air / blowing cycle can be executed at a fixed frequency (e.g., once per hour). At certain specific times, such as after daily drip irrigation and fertilization has been completed and after a period of infiltration and settling, the system needs to perform a waste discharge operation. Waste discharge can be controlled by detecting the difference between the EC value of the discharged nutrient solution and the EC value of the dripped nutrient solution, or by using empirical values. When waste discharge is required, the drip irrigation nutrient solution exceeds the substrate's saturation storage value, causing nutrient solution to seep out, thus forming waste liquid. The waste liquid flows directly from the main body 1 of the planting chamber into the waste discharge pipe 8. By opening the solenoid valve 9 above the waste liquid tank 10, the waste liquid is discharged into the waste liquid tank 10. At this time, the controller determines whether the preset waste discharge time has been reached. If the time has not been reached, the current cycle ends, waiting for the triggering of the next compressed air / blowing cycle. If the determination is yes, the controller sends an energizing command to the normally closed solenoid valve to open it. Waste fluid accumulated inside the implantation chamber 1 flows into the waste fluid tank 10 through the waste drain hole 15 and the waste drain pipe 8 under the influence of gravity. This waste draining process also lasts for a preset time (e.g., 2 minutes) to ensure that the chamber is emptied. After the waste draining is completed, the controller cuts off the power supply to the solenoid valve, causing it to close automatically, and the implantation chamber 1 returns to a sealed state.
[0047] Next is the waste liquid treatment stage. A liquid level sensor can be installed inside the waste liquid tank 10. When the sensor detects that the waste liquid level has reached a preset threshold, it will trigger the controller to start the heating and evaporation system. The heating and evaporation system will continue to operate until the liquid level drops to the minimum point or stops after a preset period of time. It can be understood that this process is independent of the gas compression and waste discharge cycle and is carried out on demand.
[0048] Through the above structure and method, this embodiment successfully integrates multiple key aspects required for plant growth, such as root zone oxygen supply, canopy ventilation, root zone temperature control, and waste liquid treatment, into a single system, achieving synergistic effects and providing a complete, efficient, and environmentally friendly solution for high-density indoor planting.
[0049] Example 2 This embodiment provides a modified waste liquid treatment solution, aiming to provide a waste liquid evaporation method with lower energy consumption and higher safety. In this embodiment, the overall structure of the system, including the main body 1 of the implantation chamber, the formation of the dual airflow channels, the waste discharge system, and the air inlet temperature control unit, is basically the same as that of Embodiment 1. The main difference lies in the specific composition of the waste liquid evaporation system inside the waste liquid tank 10.
[0050] In Example 1, the waste liquid evaporation system used a heating evaporation system. In contrast, in this example, the waste liquid evaporation system uses one or more high-power ultrasonic atomizers instead of heating elements. The ultrasonic atomizer is installed at the bottom or side wall of the waste liquid tank 10 and is immersed in the collected waste liquid. The ultrasonic atomizer is electrically connected to the system controller.
[0051] Its working process is similar to that of Example 1: In the waste liquid treatment stage, after the waste liquid tank 10 collects waste liquid through the waste discharge pipe 8 and the normally closed solenoid valve, the controller starts the ultrasonic atomizer. The ultrasonic atomizer uses the high-frequency mechanical vibration (usually at 1.7MHz or 2.4MHz) generated by its transducer to convert electrical energy into mechanical energy. When this high-frequency vibration acts on the liquid, it can disperse the liquid water into tiny droplets with a diameter of only a few micrometers, thereby forming a cold mist. Because these tiny droplets have a huge specific surface area, they can achieve rapid vaporization and evaporation at room temperature. The generated water mist can be naturally diffused through the vent at the top of the waste liquid tank 10, or blown out with the assistance of a small fan.
[0052] Compared to the heating evaporation scheme in Example 1, the ultrasonic atomization scheme used in this example has the following significant advantages: 1. Lower energy consumption: The ultrasonic atomization process does not require heating the entire tank of water to its boiling point. Its energy is mainly used to overcome the surface tension of water. Therefore, the energy consumption for evaporation per unit volume of water is much lower than that for heating evaporation, saving a significant amount of electricity in long-term operation. 2. Higher safety: The entire evaporation process is carried out at room temperature, without involving high-temperature components or boiling water, thus avoiding the risk of burns and potential equipment aging or fire hazards caused by high temperatures, thereby improving the overall safety of the system. 3. Environmental regulation function: The generated cold mist can effectively supplement and regulate the air humidity in the planting room, especially suitable for dry climates or seasons. By directly discharging the water mist into the planting environment, it is possible to achieve both waste liquid treatment and environmental humidification in one machine, further improving the overall efficiency of the system.
[0053] In summary, this embodiment provides a preferred technical solution that achieves zero emissions and disease prevention while also offering advantages in energy saving and safety.
[0054] Example 3 Based on the structure of Example 1, this embodiment introduces sensors and adaptive control logic, aiming to upgrade the system from open-loop control based on fixed timing to closed-loop intelligent control based on real-time environmental feedback, thereby more accurately meeting the needs of plants at different growth stages and under environmental changes, and further saving energy.
[0055] The system structure of this embodiment adds several sensors and an air intake control valve to the structure of embodiment 1. Specifically, a temperature and humidity sensor is deployed in at least one area inside the plant canopy to monitor the temperature and humidity of the microenvironment between leaves in real time; simultaneously, a liquid level sensor is installed inside the main body 1 of the planting chamber near the waste outlet 14 to monitor the height of the liquid accumulation in the chamber in real time. In addition, an air intake control valve controlled by a controller is added to the pipeline between the air intake system and the air inlet 13. Correspondingly, the system controller also adopts a microprocessor unit capable of acquiring and processing these sensor signals, such as a microcontroller or embedded system with multiple input / output interfaces.
[0056] Based on the aforementioned hardware, the system's operating method has also been adjusted to an adaptive intelligent control mode: 1. Adaptive Compressed / Blowered Air Control: The controller no longer relies solely on fixed time intervals to initiate the compressed / blowing cycle, but instead uses real-time data from temperature and humidity sensors as the primary trigger. The controller is configured to immediately trigger a compressed / blowing cycle when the relative humidity inside the canopy, as measured by the temperature and humidity sensors, remains above a preset humidity threshold (e.g., 95%) for a continuous period (e.g., 5 minutes). At this time, the controller opens the intake control valve and starts the air pump for forced ventilation to reduce canopy humidity, thereby breaking conditions that may lead to disease. This on-demand response control logic can more effectively address sudden increases in humidity caused by sudden changes in light, irrigation operations, or fluctuations in the external environment, greatly improving the timeliness and effectiveness of disease prevention. Once the humidity returns to a safe range, the controller can stop ventilation early, even if the preset ventilation time has not yet elapsed, thus saving energy consumption of the air pump.
[0057] 2. Adaptive Waste Discharge Control: Waste discharge operations are no longer dependent on fixed time points. The controller monitors the signal from the liquid level sensor inside the main body 1 of the planting chamber in real time. After drip irrigation or sprinkler irrigation, the controller only issues a command to open the normally closed solenoid valve for waste discharge when the liquid level sensor detects that the liquid level in the chamber has reached the preset waste discharge height. Furthermore, the controller continuously monitors the liquid level until the signal from the liquid level sensor indicates that the liquid level has dropped to the lowest point (i.e., the empty state), at which point the controller closes the normally closed solenoid valve. This control method based on liquid level feedback achieves true "on-demand waste discharge." Compared to the fixed-duration waste discharge method, it ensures that waste liquid is emptied every time, avoiding incomplete or excessive waste discharge caused by changes in irrigation volume, and also avoids the valve being open when there is no liquid in the chamber, thereby reducing unnecessary energy consumption and equipment wear.
[0058] By introducing sensors and adaptive control algorithms, this embodiment enables the entire implantation chamber system to have adaptive control capabilities. The system operates more intelligently and purposefully, with energy (such as the power consumption of the air pump and solenoid valves) consumed only when actually needed, achieving significant energy savings. More importantly, the system responds more quickly and accurately to adverse environmental factors that may cause disease (such as high humidity and waterlogging), thereby further improving the success rate, stability, and quality of the final product.
[0059] Example 4 This embodiment aims to provide a simplified and lower-cost intake air temperature regulation solution, which is particularly suitable for application scenarios where the requirements for root zone temperature are not so extreme or the external ambient temperature is relatively mild.
[0060] The overall system structure of this embodiment is largely similar to that of Embodiment 1, with the core difference being the specific construction and working principle of the inlet temperature control unit. In Embodiment 1, the inlet temperature control unit employs active temperature control, which precisely controls the water temperature in the tank through a refrigeration or heating system; however, in this embodiment, the inlet temperature control unit employs passive temperature control.
[0061] Specifically, the air intake temperature control unit here also includes an energy storage water tank 6 and a heat exchange structure disposed within the energy storage water tank 6. As a preferred implementation, this heat exchange structure includes pipes and a water pump, which directly pumps water from the tank to the heat exchange plate 4 within the air intake pipe 2 for heat exchange with the gas. However, unlike Embodiment 1, this energy storage water tank does not contain any active cooling or heating system; it merely acts as a passive heat exchange buffer, and the internal water temperature dynamically balances with the ambient air temperature within the planting room over time.
[0062] Its working process is as follows: When the centrifugal fan 3 is started, the air drawn from the indoor environment, whose temperature may fluctuate, must first flow through a long coil submerged in water before entering the main body 1 of the implantation chamber. Since the specific heat capacity of water is much greater than that of air, the large amount of water in the energy storage tank 6 constitutes a thermal flywheel with huge thermal inertia.
[0063] When the centrifugal fan 3 draws in a relatively warm stream of air for a short period (e.g., on a summer afternoon), the air is effectively pre-cooled as it flows through the coils surrounded by relatively cool water, its heat transferred to the water. Conversely, if the centrifugal fan 3 draws in a cold stream of air (e.g., in winter or when the air conditioner is first turned on), it is preheated by the relatively warm water as it passes through the coils. Ultimately, regardless of fluctuations in the inlet air temperature, the gas temperature entering the main body 1 of the planting chamber is effectively "smoothed" after being processed by this passive inlet temperature control unit, thus preventing severe temperature spikes from directly impacting the plant roots.
[0064] Although the solution in this embodiment cannot precisely control the intake air temperature to 22°C as in Embodiment 1, it can effectively buffer and mitigate the direct impact of drastic fluctuations in ambient temperature (such as diurnal temperature differences, air conditioning start-up and shutdown) on plant roots with extremely low hardware costs and zero operating energy consumption. It is understood that this still has a very significant beneficial effect on maintaining the stability of root physiological activities and preventing plants from experiencing stress responses due to drastic temperature changes. Therefore, this embodiment provides a more economical and universally applicable implementation option for the technical solution of this invention.
