Technical Field
[0001] This utility model relates to the field of edible fungi cultivation technology, specifically to an edible fungi cultivation facility that utilizes an air-source temperature control system. Background Technology
[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. Edible fungi contain a variety of nutrients needed by the human body, such as amino acids, proteins, carbohydrates, lipids, vitamins, and minerals. With the gradual improvement of people's living standards in my country, the domestic consumption of edible fungi is increasing day by day. Therefore, in rural areas, the edible fungi industry is becoming a pillar industry for farmers to get rich and for the modernization of agricultural industry.
[0003] To meet the growing demand for edible fungi, the use of cultivation facilities for edible fungi production has become mainstream. During cultivation, edible fungi have extremely strict requirements for their growth environment, especially temperature and humidity. Different varieties of edible fungi require specific and stable temperature and humidity environments at each growth stage. Traditional edible fungi cultivation facilities mostly use boilers and electric heaters for heating, and water curtains and ground sprinklers for cooling and humidification. These methods suffer from high energy consumption, poor temperature and humidity control precision, and high operating costs. Especially during summer cooling and winter heating, energy costs account for a large proportion of the total cultivation cost. Summary of the Invention
[0004] To address the aforementioned issues, this invention provides an edible fungi cultivation facility that utilizes an air-source temperature control system to efficiently, precisely, and energy-savingly regulate the temperature and humidity environment required for edible fungi growth.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an edible fungus cultivation facility regulated by an air source temperature control system, including a cultivation room, an electrical control box, an air source heat pump unit, an indoor heat exchanger, an outdoor heat exchanger, a circulating fan, a humidification component, and a monitoring component.
[0006] The inner wall of the cultivation room is covered with polyurethane foam wall panels and has ventilation openings. The interior is equipped with a multi-layer three-dimensional cultivation rack for placing the inoculum. The electrical control box contains a controller and is installed on the side wall of the cultivation room. It is electrically connected to each electrical control component through wires.
[0007] The air source heat pump unit is installed outside the planting room, the indoor heat exchanger and circulating fan are installed inside the planting room, and the outdoor heat exchanger is installed outside the planting room. The air source heat pump unit is connected to the indoor heat exchanger and the outdoor heat exchanger through a four-way reversing valve and copper pipes respectively, forming a complete closed loop. The cooling and heating modes can be switched by switching the direction of the four-way valve.
[0008] The humidification assembly includes a humidifier and a water supply tank. The humidifier is a high-pressure micro-mist humidifier or an ultrasonic humidifier, and is installed outside the planting room with the spray pipe extending into the planting room. The water supply tank is placed below the humidifier, and the water inlet of the humidifier is connected to the water supply tank through a water pump and a water supply pipe.
[0009] The monitoring components include temperature and humidity sensors installed inside the growing room.
[0010] As an optimized solution for this case, in order to improve the uniformity of temperature and humidity distribution, achieve uniform air supply, and avoid local environmental deviations, an air handling box is installed on the inner wall of the planting room. The air handling box is divided into an exchange zone and an air supply zone by a partition. The exchange zone is located in front of the air supply zone. The partition has an air supply vent, and the size of the air supply vent gradually decreases from the exchange zone to the air supply zone, thus prolonging the heat exchange time between the air and the indoor heat exchanger. The side wall of the exchange zone has a return air vent that connects to the inside of the planting room, and an air filter is installed on the return air vent. The side wall of the air supply zone has an exhaust vent, forming a forced circulation air duct with the return air vent to improve the uniformity of temperature and humidity distribution. The indoor heat exchanger is installed in the exchange zone, and the coil surface of the indoor heat exchanger is perpendicular to the airflow direction to maximize heat exchange area. The circulating fan is a backward centrifugal fan, installed in the air supply zone, with its air inlet facing the air supply vent of the partition so as to directly draw in the air after heat exchange. The air outlet is opposite to the exhaust vent of the air supply zone.
[0011] Furthermore, an air supply duct is installed on the exhaust port of the air handling box, which extends to the long side inside the planting room. Multiple evenly distributed air outlets are opened on the duct wall to achieve uniform air supply and avoid local environmental deviations.
[0012] As an optimized solution for this case, to facilitate the growth of edible fungi and control the carbon dioxide concentration in the cultivation room, a carbon dioxide concentration sensor and an exhaust fan are installed in the cultivation room. Both are electrically connected to the electrical control box via wires, and a check valve is installed at the exhaust fan outlet. When the carbon dioxide concentration exceeds a preset value, the electrical control box activates the exhaust fan to ventilate, expelling excess carbon dioxide and replenishing fresh air.
[0013] As an optimization solution for this case, in order to prevent the air source heat pump from becoming less efficient or even shutting down in cold weather, thereby affecting the growth of edible fungi, an electric heating element is installed in the air supply duct, and the electric heating element is electrically connected to the electrical control box; when the outdoor ambient temperature is extremely low, causing the air source heat pump unit to have insufficient heating capacity or be unable to start normally, the electric heating element is activated by the electrical control box for auxiliary heating.
[0014] Beneficial effects: ①. This utility model installs the electrical control box, air source heat pump unit, indoor heat exchanger, outdoor heat exchanger, circulating fan, humidification component and monitoring component on the planting room. By using air source heat pump as the core temperature control equipment, its heating energy efficiency ratio is much higher than that of traditional electric heating, and its cooling energy efficiency ratio is also high, which significantly reduces the energy consumption in the heating and cooling process and has low operating costs.
[0015] ② Furthermore, by integrating sensors and an electrical control box, it achieves automated closed-loop control of temperature and humidity with high control precision. It can stably maintain the optimal environmental conditions required for each growth stage of edible fungi, which is conducive to improving yield and quality. Moreover, by setting different parameters through the electrical control box, it can adapt to the cultivation of edible fungi with different temperature and humidity requirements, and has high application value.

Example 1
[0023] like Figure 1-3As shown, this embodiment discloses an edible fungus cultivation facility regulated by an air source temperature control system, including a cultivation room 1, an electrical control box 2, an air source heat pump unit 3, an indoor heat exchanger 4, an outdoor heat exchanger 5, a circulating fan 6, a humidification component, and a monitoring component.
[0024] See Figure 1 The inner wall of the planting room 1 is covered with polyurethane foam wall panels and has ventilation openings. The interior is equipped with a multi-layer three-dimensional planting rack for placing the inoculum. The electrical control box 2 is equipped with a controller and is installed on the side wall of the planting room 1. It is electrically connected to each electrical control component through wires.
[0025] from Figure 1 and Figure 2 As can be seen, the air source heat pump unit 3 is installed outside the planting room 1, the indoor heat exchanger 4 and the circulating fan 6 are installed inside the planting room 1, and the outdoor heat exchanger 5 is installed outside the planting room 1. The air source heat pump unit is connected to the indoor heat exchanger 4 and the outdoor heat exchanger 5 through a four-way reversing valve and copper pipes respectively, forming a complete closed loop. By switching the direction of the four-way valve, the two modes of cooling and heating can be switched.
[0026] See Figure 1 and Figure 2 The humidification assembly includes a humidifier 7 and a water supply tank 8. The humidifier 7 is a high-pressure micro-mist humidifier 7, which is installed outside the planting room 1 and the spray pipe 9 extends into the planting room 1. The water supply tank 8 is placed below the humidifier 7. The water inlet of the humidifier 7 is connected to the water supply tank 8 through a water pump and a water supply pipe to supply water.
[0027] See Figure 3 An air handling unit 12 is installed on the inner wall of the planting room 1. The air handling unit 12 is divided into an exchange zone 16 and an air supply zone 17 by a partition 18. The exchange zone 16 is located in front of the air supply zone 17. An air supply vent is provided on the partition 18, and the size of the air supply vent gradually decreases from the exchange zone 16 to the air supply zone 17, thereby prolonging the heat exchange time between the air and the indoor heat exchanger 4. A return air vent is provided on the side wall of the exchange zone 16, which is connected to the inside of the planting room 1. An air filter is installed on the top, and an exhaust port is opened on the side wall of the air supply zone 17, forming a forced circulation air duct between it and the return air port. The indoor heat exchanger 4 is installed in the exchange zone 16, and the coil surface of the indoor heat exchanger 4 is perpendicular to the airflow pattern to maximize heat exchange area. The circulating fan 6 is a backward centrifugal fan, installed in the air supply zone 17, with its air inlet facing the air supply port of the partition so as to directly draw in the air after heat exchange. The air outlet is opposite to the exhaust port of the air supply zone 17.
[0028] An air supply duct 13 is installed on the exhaust port of the air handling box 12. The air supply duct 13 extends to the long side inside the planting room 1. Multiple evenly distributed air outlets are opened on its duct wall to achieve uniform air supply and avoid local environmental deviations.
[0029] See Figure 2 The monitoring components include a temperature sensor 10 and a humidity sensor 11 installed inside the planting room 1. Example 2
[0030] like Figure 1 and Figure 3-4 As shown, the specific structure and implementation method are as illustrated in Example 1, with the difference being: See Figure 3 The planting room 1 is equipped with a carbon dioxide concentration sensor 14 and an exhaust fan 15, both of which are electrically connected to the electrical control box 2 via wires. A check valve is installed at the air outlet of the exhaust fan 15. When the carbon dioxide concentration exceeds a preset value, the electrical control box 2 starts the exhaust fan 15 to ventilate, expelling excess carbon dioxide and replenishing fresh air.
[0031] An electric heating element is installed inside the air supply duct 13, and the electric heating element is electrically connected to the electrical control box 2. When the outdoor ambient temperature is extremely low, causing the air source heat pump unit 3 to have insufficient heating capacity or fail to start normally, the electrical control box 2 will activate the electric heating element for auxiliary heating.
[0032] During temperature control, the controller in the electrical control box 2 compares the feedback from the temperature sensor 10 with the set value. If heating is required, the air source heat pump unit 3 is controlled to operate in heating mode. The process is as follows: air source heat pump unit 3 (four-way valve reversing, compressor doing work) → indoor heat exchanger 4 (acting as a condenser, releasing heat to the room) → outdoor heat exchanger 5 (acting as an evaporator, absorbing heat from the room) → back to the unit; if cooling is required, the cooling mode is operated. The process is as follows: air source heat pump unit 3 (compressor doing work) → outdoor heat exchanger 5 (acting as a condenser, releasing heat to the room) → indoor heat exchanger 4 (acting as an evaporator, absorbing heat from the room) → back to the unit.
[0033] During the above process, the circulating fan 6 runs continuously. Indoor air is drawn in from the return air inlet by the circulating fan 6, cooled or heated by the indoor heat exchanger 4, and then evenly blown to various areas of the planting room 1 through the air supply duct 13, forming a uniform and forced circulation airflow organization to promote heat exchange and temperature uniformity.
[0034] During humidity control, the controller in the electrical control box 2, based on feedback from the humidity sensor 11, will start the humidifier 7 and water pump when the humidity is lower than the set value, and spray mist into the planting room 1 until the humidity reaches the set range.
[0035] During ventilation control, the controller in the electrical control box 2, based on feedback from the carbon dioxide concentration sensor 14, will start the exhaust fan 15 for a period of time when the concentration exceeds the set upper limit, introducing fresh outdoor air and expelling excess carbon dioxide until the set range is reached.
[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
