Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to a constant temperature and humidity control box for a laboratory. Background Art

[0002] In the laboratory, in order to obtain more accurate experimental data, strict requirements are placed on the constant temperature experimental environment. Therefore, for the laboratory, the role of the constant temperature box is quite important. It will have a great impact on the laboratory's research process and research results. At the same time, more accurate research results will have a positive effect on the practical application of the resulting experimental results.

[0003] Most existing laboratories use constant temperature and humidity control boxes. Since the air inside the box is not circulated, the cooling and heating inside the box are not uniform and troublesome. Moreover, after conducting a high humidity experiment, the existing constant temperature and humidity box needs to adjust the internal humidity. Generally, the humidification device is turned off to allow the humidity to decrease naturally, which often takes a long time and is not conducive to improving the experimental efficiency. In addition, during the temperature adjustment process, the adjustment speed is too slow and unstable. Utility Model Content
