The key technical key points of the application are that the principle of air conditioner heat exchange is fully used for reference, and effective improvement is carried out, specifically:

(1) fully using for reference the principle of heat exchange of an air conditioner, the air flow firstly flows through the evaporator to be cooled and dehumidified; the saturated content of the water vapor in the air is different under different temperatures and the same pressure condition, the higher the temperature is, the higher the saturated content of the water vapor is, the lower the temperature is, the saturated content of the water vapor is, and in the air with the same quality of saturated moisture, the moisture content in the air with high temperature is higher than that in the air with low temperature;

(2) the dehumidified low-temperature airflow flows through the radiator again to increase the temperature of the air, and then returns to the fermentation chamber, so that the temperature of the air in the chamber is kept from being lost, the energy consumption of extra heating is reduced, and meanwhile, the high-temperature dry air is evaporated by utilizing the water vapor of the materials in the chamber;

(3) the gas in the fermentation cabin returns to the fermentation cabin after being dehumidified and heated, and does not overflow to the outside of the fermentation cabin, so that air pollution caused by the gas in the fermentation cabin is avoided.

The application has the following main advantages:

(1) the heat loss brought away by directly discharging the gas in the cabin is reduced;

(2) after the dehumidified warm gas flows back into the fermentation chamber, the air humidity in the chamber is reduced, so that the water in the chamber can be evaporated more quickly;

(3) the air pollution caused by directly discharging the gas in the cabin is reduced, some peculiar smell gas is emitted more or less in the cabin, and the pollution of the outside air is certainly caused by directly discharging the gas;

(4) when the water vapor in the cabin is dehumidified and liquefied through the evaporator, a lot of vaporization heat can be released, and the heat energy is absorbed by heat exchange medium gas, and is brought to the end of the radiator to release reflux gas in the heating cabin.
