[0002] At present, the demand for edible fungi in my country is increasing day by day, and nowadays, the factory cultivation of edible fungi is an inevitable trend. In the traditional edible fungi cultivation process, the air supply system in the mushroom house is mainly in the form of internal circulation of the air conditioner indoor unit, and the indoor air is directly returned and directly sent to the mushroom house from the side, and the outside fresh air is sent to the room in the form of a fan or wind cabinet. However, there are still many rare mushroom species and some mushroom species with more stringent growth environment requirements that do not have a more complete factory cultivation process. One reason is that this air supply system has certain defects.

[0003] Firstly, the air outlet of the air cooler is directly sent to the mushroom house from the side. The mushrooms on the top floor are easily blown directly by the higher wind speed, which may directly affect their growth. In addition, this form of air supply can easily cause uneven air supply in different areas, resulting in inconsistent growth rates of edible fungi in different positions and the production of low-quality defective mushrooms.

[0004] Secondly, the source of fresh air in the mushroom house is directly introduced into the mushroom house from the outside, which will cause the temperature of the area near the fresh air inlet to be higher, the temperature in the mushroom house to be uneven, and the mixture of cold and hot air will easily form condensation water dripping on the mushroom bags, affecting the growth of mushrooms.

[0028] like Figure 1 and Figure 2 The air supply system of an edible fungus warehouse shown includes a mushroom house and an air cooler 1 for supplying air to the mushroom house, two rows of mushroom racks 13 are symmetrically arranged in the mushroom house, two air outlet pipes 8 are symmetrically installed in the mushroom house, the two rows of mushroom racks 13 are located between the two air outlet pipes 8, the two rows of mushroom racks 13 are arranged at intervals, the air outlet pipes 8 and the mushroom racks 13 are arranged at intervals, and the air outlet pipes 8 are located above the mushroom racks 13; the air outlet pipes 8 are provided with air holes 9 with openings facing downward, and a plurality of air holes 9 are evenly arranged along the length direction of the air outlet pipes 8; a planting layer for planting edible fungi is provided on the mushroom racks 13, and a plurality of planting layers are evenly arranged on the mushroom racks 13 from top to bottom; the air holes 9 can blow air to the planting layer on the mushroom racks 13 located in the middle and below thereof; the air cooler 1 can supply air to the air outlet pipes 8, and an exhaust valve 10 is also installed on the mushroom house.

[0029] With such arrangement, through the design of the air supply duct and the air outlet, the air supply system can achieve a uniform circulating airflow effect between the multiple planting layers on the mushroom rack 13; in this way, the temperature, humidity and oxygen level in each area of ​​the mushroom house can be effectively adjusted and balanced, thereby ensuring that the mushrooms can be in the most suitable environmental conditions throughout the entire growth cycle, and can also reduce the temperature gradient and humidity difference in the mushroom house, prevent overheating or overhumidification in local areas, thereby reducing the occurrence of diseases and pests, which is of great significance for ensuring the growth quality and yield of edible fungi.

[0030] In this embodiment, a static pressure box 4 is provided in the mushroom house, and the static pressure box 4 is connected to two air outlet pipes 8 through two indoor air supply pipes 6 respectively, and the air cooler is connected to the static pressure box 4 through the outdoor air supply pipe 3; the exhaust valve 10 and the indoor air supply pipe 6 are respectively arranged on two opposite sides of the mushroom house. Furthermore, a wind shield 5 for distributing the air volume is installed in the static pressure box 4. Such an arrangement can evenly distribute the air volume of the two air outlet pipes 8, so that the air volume on both sides of the mushroom house is more even.

[0031] In this embodiment, the indoor air supply pipe 6 and the air outlet pipe 8 are connected through the air pipe elbow 7, and a stainless steel air distribution net 16 is installed at the outlet of the air pipe elbow 7, and the air enters the air outlet pipe 8 after passing through the air distribution net 16. Such a configuration can effectively adjust the wind speed in the air outlet pipe 8 and make the air supply uniform and stable.

[0032] In this embodiment, the air cooler 1 is arranged outside the mushroom house, and a fresh air inlet 2 for extracting outside air is arranged on the air cooler 1; a return air duct 11 for extracting air from the mushroom house is installed between the mushroom house and the air cooler 1. With such an arrangement, the air cooler 1 does not need to be used indoors, which greatly reduces the source of indoor noise, and does not cause the air cooler 1 to drip condensed water. Turning on the indoor return air can regulate the pressure, temperature and humidity in the mushroom house, reuse the treated air resources, and improve the air utilization rate.

[0033] In this embodiment, the material of the air outlet pipe 8 is PE material; the air outlet pipe 8 is hoisted on the top of the mushroom house by a steel wire rope or a nylon rope. In this way, the indoor air is completely supplied by the air duct, the structure is symmetrical and beautiful, the supporting structure is simple, the space utilization rate is high, and most of the air supply pipe sections are made of PE material, which is low in cost, easy to open holes and easy to install.

[0034] In this embodiment, a temperature and humidity sensor 14 and a carbon dioxide sensor 15 are installed in the middle of the mushroom house, and both the temperature and humidity sensor 14 and the carbon dioxide sensor 15 are electrically connected to the air cooler 1. Furthermore, the mushroom house is covered with an insulation panel 12. Such an arrangement can better ensure the stability of the environment in the mushroom house.

[0035] In this embodiment, the distance between two adjacent air holes 9 on the air outlet pipe 8 is 300 mm. In other embodiments, the distance between two adjacent air holes 9 on the air outlet pipe 8 can be adjusted according to the height of the mushroom house and the width of the aisle.

[0036] In this embodiment, a filter device for purifying air is also included, and the air enters the mushroom house after passing through the filter device.

[0037] In this embodiment, the exhaust valve 10 is a positive pressure exhaust valve; the exhaust valve 10 adopts a positive pressure exhaust form, the exhaust valve 10 automatically exhausts air outward through the self-hanging louver air outlet, and the exhaust valve 10 is provided with an insect-proof net.

[0038] The control process of the above air supply system is as follows:

[0039] When the air supply system is not turned on in the mushroom house, the temperature in the mushroom house will rise due to the high temperature environment and the heat generated by the mushrooms themselves, and the carbon dioxide concentration in the mushroom house will gradually increase due to the respiration of the mushrooms. The air supply system detects the temperature, humidity and carbon dioxide concentration in the mushroom house through the temperature and humidity sensor 14 and the carbon dioxide sensor 15, and determines whether the multifunctional air cooler 11 is supplying air by comparing the detected value with the set value;

[0040] When the air supply system is turned on, the air cooler 1 turns on the centrifugal fan and outputs the processed air through the outdoor air supply duct 3. The outdoor air supply duct 3 passes through the insulation storage panel 12 and is connected to the static pressure box 4. The wind shield 5 inside the static pressure box 4 evenly distributes the wind to the air outlets on both sides of the static pressure box 4. The air outlets are connected to the indoor air supply duct 6, and then the wind direction is changed through the air duct elbow 7. After passing through the air equalizing net 16 at the end of the air duct elbow 7, it enters the air duct and then enters the mushroom house from the air holes 9 on the air duct for air supply.

[0041] like Figure 2As shown, the air entering the mushroom house blows toward the ground of the mushroom house and the planting layer in the middle and lower positions on the planting racks. The air passes through the gap between two adjacent planting layers, and then passes through the air convection in the middle and lower sides of the two rows of planting racks and moves upward. Due to the setting of the air holes 9, wind pressure is formed on the upper and lower sides of the planting racks close to the air outlet pipe 8. The air between the two rows of planting racks passes through the planting layers in the middle and above positions on the planting racks under the action of the pressure difference.

[0042] The hot air in the mushroom house is continuously and automatically discharged through the positive pressure exhaust valve 10, thereby improving the cooling capacity utilization rate of the system.

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
