Interpretation of high and low temperature humidity and heat test chamber

The high and low temperature humidity test chamber is tested in an environment where the temperature is not uniform and the data will be erroneous. Why?
1. The sealing is not good, the sealing strip is not customized, there are gaps, and the door is leaking air, etc., then affects the uniformity the temperature of the working space.
2. There are doubts in the planning, which leads to the internal layout and space layout of the high and low temperature humidity and heat test chamber.
3. The organization of the experimental target space in the working room of the high and low temperature humidity and heat test chamber. If the experimental samples which can affect the overall internal thermal convection are placed in the working room of the high and low temperature humidity and heat test chamber, it will definitely affect the temperature uniformity.e internal to some extent. Sex, that is, temperature uniformity.

4. If the volume of the test target is too large, or the test target is placed in the high and low temperature test box work room or the method is not appropriate, the convection of indoor air will be blocked and a large temperature uniformity error will also occur.
5. Due to the different layout of the inner wall of the high and low temperature humidity test chamber, the temperature of the inner wall of the test chamber will also be uneven, which will affect the heat convection in the work room and will cause uniformity errors. internal temperature.
6. Because the heat transfer coefficients of the front, rear, left, right, upper and lower sides of the working room box wall are different, and some have thread holes, detachment holes.ection, test holes, etc., some of them have heat dissipation and heat transfer, so the box temperature is not the same. Uniformity, then the heat transfer by radiation convection on the box wall is not uniform, which affects the uniformity of the temperature field.
