Description

technical field [0001] The invention relates to a refrigeration device in an environment requiring stable relative humidity, such as edible fungus cultivation and a greenhouse, and a method for controlling the relative humidity during refrigeration. Background technique [0002] In fields such as edible fungi cultivation and greenhouses, such as mushroom houses, greenhouses, and wet and cold fresh-keeping environments, there is a high requirement for stable relative humidity while cooling. Humidity will drop. In the above-mentioned places where the relative humidity of the environment is relatively high, how to ensure the stability of the relative humidity during cooling is a common problem. The common solution is to configure a humidifier, but there are still problems such as the relative humidity cannot be controlled during the cooling process, and the relative humidity of the environment is unstable after humidification.

AI Technical Summary

Problems solved by technology

The device is simple in structure, easy to use, low in energy consumption, and greatly reduces the cost of use. It is mainly suitable for off-season cultivation of edible fungi and crops in greenhouses, and can effectively improve the yield and quality of crops. The humidification system of the steam generator is used to achieve cooling while increasing the humidity, therefore, it cannot maintain the stability of the relative humidity
