Humidity control assembly, refrigerating system and humidity control method of refrigerating system

The invention discloses a humidity control assembly, a refrigerating system and a humidity control method of the refrigerating system, relates to the field of refrigerating systems, and solves the problems that in the prior art, humidity is controlled through temperature control, so that the humidity at part of temperature exceeds a preset range, and accurate humidity control cannot be achieved. The humidity control assembly comprises a weight detection assembly and a humidity adjusting assembly, the weight detection assembly is arranged in a to-be-controlled space and used for determining the weight of water vapor in the to-be-controlled space, and the humidity adjusting assembly is arranged in the to-be-controlled space. The humidity adjusting assembly is used for adjusting the humidity of the to-be-controlled space and making the weight of water vapor in the to-be-controlled space within a first preset water vapor weight range. According to the control assembly and the humidity adjusting assembly, the humi
