Constant temperature and humidity test chamber measurement method and fan knowledge
------Collecting literature of Huanyi instrument
A. Measurement method of constant temperature and humidity test chamber:
First of all, let's talk about the location of the measurement point:
1. When the equipment volume is less than 2m³, there are 9 temperature points and 3 humidity points
2. The equipment volume is greater than 2 m³, 15 temperature points, 4 temperature points
Secondly, the measurement temperature and humidity point should generally select the upper limit, lower limit and center point of the equipment use range, and the actual commonly used temperature and humidity points can also be selected according to user needs. The last thing to talk about is that the measurement is carried out under no-load conditions. If there is a load, the load should be stated in the certificate.
A. The editor of the fan wind speed adjustment ring instrument of the constant temperature and humidity test chamber provides the answers for the majority of users as follows:
The following introduces the adjustment method of the fan speed of the constant temperature and humidity test chamber:
1. When the constant temperature and humidity test chamber is in the heating process, the circulating fan runs at high speed, which can speed up the air = convection in the working room, shorten the heating time, and improve work efficiency;
2. When the temperature in the working room is close to the control temperature, the constant temperature and humidity test chamber instrument automatically adjusts the circulating fan from high-speed operation to low-speed operation to make the air in the working room
Smooth convection, and effectively extend the life of the circulating fan;
3. If you do not need to use the automatic wind speed adjustment function, you can adjust the high and low speed control parameters to 999.9 according to the control parameter adjustment method, and the circulating fan will always be in high-speed operation.
