[0002] Edible fungi contain nutrients such as amino acids, proteins, carbohydrates, lipids, vitamins, minerals, etc., and have good effects in inhibiting tumors, regulating immunity, and lowering cholesterol. Therefore, with the gradual improvement of people's living standards in my country, the domestic consumption of edible fungi is increasing, and most urban residents in China have become the main consumers of edible fungi. Assuming that each person in a city with a population of 3 million consumes 100g of edible fungi every day, a city can consume 300,000 kilograms of edible fungi every day, and the annual consumption can reach 1.1 million tons. There are more than 50 cities in my country with a population of more than 3 million. The consumption of these cities alone is more than five times the current production of edible fungi. In addition, with the strong support of the country for the agricultural sector in recent years, it is expected that in the next 20 years, my country's consumption of edible fungi will be more than ten times the current production capacity. The development prospects of the edible fungi market are very broad.

[0026] The supply and return water pipeline 4 includes a first water channel, a second water channel, a third water channel and a fourth water channel; the water outlet of the closed cooling tower 1 and the water inlet of the evaporator 3 are connected via the first water channel, and the water inlet of the closed cooling tower 1 and the water outlet of the evaporator 3 are connected via the second water channel; the water outlet of the refrigeration unit 16 and the water inlet of the evaporator 3 are connected via the third water channel, and the water inlet of the refrigeration unit 16 and the water outlet of the evaporator 3 are connected via the fourth water channel; a first valve 5 is provided on the first water channel, a second valve 7 is provided on the second water channel, a third valve 6 is provided on the third water channel, and a fourth valve 8 is provided on the fourth water channel; a water pump 2 for supplying water to the evaporator 3 is provided in the closed cooling tower 1.

[0027] Such a setting can make full use of the energy of the external environment to cool the room. Compared with directly using the cooling mode of the refrigeration unit 16, it reduces the overall energy consumption of room cooling; it can solve the problem of high infection rate of mushroom bags grown by farmers; the cultivation process of wood decaying fungi is realized in this room. Ordinary farmers can use this system to plant short-cycle mushroom seeds twice every quarter. Not only is the investment small, but it can also achieve seasonal planting and increase profits.

[0028] In this embodiment, the evaporator 3 includes a heat exchange component, a return air port and an air outlet. The heat exchange component is arranged between the return air port and the air outlet. An indoor fan is installed at the air outlet of the evaporator 3. The indoor fan can draw air in the cooling chamber 17 from the return air port of the evaporator 3, and the air is discharged from the air outlet of the evaporator 3 after heat exchange.

[0029] In this embodiment, a fresh air unit 14 is arranged outside the cooling chamber 17, and the fresh air unit 14 supplies air to the cooling chamber 17 through the air duct 15; the air outlet of the air duct 15 is arranged toward the evaporator 3, and the air duct 15 is made of galvanized iron sheet.

[0030] In this embodiment, it also includes a storage temperature probe 10 for detecting the storage temperature of the cooling chamber 17, a material temperature probe 11 for detecting the temperature of the mushroom bag pile, a water outlet temperature probe 12 for detecting the water outlet temperature of the closed cooling tower 1, and an outdoor temperature and humidity probe 13 arranged outside the cooling chamber 17; the first valve 5, the second valve 7, the third valve 6 and the fourth valve 8 are all solenoid valves.

[0032] In this embodiment, at least one set of evaporators 3 is installed in the cooling chamber 17 .

[0033] The control method for using the above-mentioned intelligent energy-saving and cooling system of the cooling chamber 17 in a sterile environment is as follows: when the mushroom bag just comes out of the sterilizing pot and enters the cooling chamber 17, the intelligent controller starts a twelve-hour countdown, and at the same time the outdoor temperature and humidity probe 13 detects the temperature and humidity of the outdoor environment. The system automatically calculates the temperature of the outlet water temperature probe 12 of the closed cooling tower 1 through the detected data, and compares it with the temperature of the material temperature probe 11. When the temperature of the material temperature probe 11 is greater than or equal to the temperature of the outlet water temperature probe 12 + 10°C temperature difference, the system enters the energy-saving and cooling mode, and when the temperature of the storage temperature probe 10 is greater than the room set temperature, the energy-saving and cooling system starts to operate; specifically, in the energy-saving and cooling mode, the evaporator 3, the first valve 5, the third valve 6, the closed cooling tower 1 and the water pump 2 are opened, and the second valve 6 and the fourth valve 8 are closed, and then the cooling chamber 17 is energy-saving and cooled through the closed cooling tower 1.

[0034] When the system calculates the time value required for cooling by the refrigeration unit 16 in this state based on the temperature of the material temperature probe 11, the target material temperature required by the mushroom bag and the cooling capacity of the refrigeration unit, and this calculated time value is greater than or equal to the system countdown value + the safety factor time value, the energy-saving cooling mode is exited, and when the temperature of the warehouse temperature probe 1010 is greater than the room set temperature, the conventional refrigeration unit 16 cooling mode is started; specifically, when the energy-saving cooling mode and the conventional refrigeration unit 16 cooling mode are switched, the closed cooling tower 1, the water pump 2, the first valve 5 and the third valve 6 are closed, and then the second valve 6, the fourth valve 8 and the refrigeration unit 16 are opened; during the operation of the conventional refrigeration unit 16 cooling mode, the refrigeration unit 16 cooling mode is exited when the temperature detected by the material temperature probe 11 drops to the target required temperature.

[0035] When the above-mentioned intelligent energy-saving cooling system for the cooling chamber 17 is used under normal conditions, the control method is as follows: when the temperature detected by the warehouse temperature probe 10 is greater than the set temperature of the warehouse, and the temperature detected by the outdoor temperature and humidity probe 13 is lower than the set temperature of the warehouse, the system directly starts the fresh air unit 14 and the terminal evaporator 33, and the system uses outdoor fresh air to cool the cooling chamber 17.

[0036] With such settings, the entire system can be started with just one button, and there is no need to worry about the allocation ratio of the energy-saving cooling time and the cooling time of the refrigeration unit 16. The system will automatically calculate it, which is simple to operate and avoids dependence on technical personnel.
