The linear temperature change of the high and low temperature test chamber is the average temperature rise and fall speed of the whole process, and the linear temperature rise and fall speed. The average speed of the whole process refers to the ratio of the difference between the highest temperature and the lowest temperature in the temperature range of the high and low temperature test chamber. The technical parameters of the variable temperature rate provided by the foreign environmental test equipment manufacturers all refer to the average rate of the whole process. .
The linear temperature rise and fall speed refers to the variable temperature rate that can be guaranteed in any 5 min period. In fact, for the rapid temperature change high and low temperature test chamber, the most difficult and most critical part of ensuring the linear temperature rise and fall is that the vortex flowmeter can reach the last 5 min of the cooling section. Cooling rate.
Therefore, the high and low temperature test chamber preferably has two parameters: the average average temperature rise and fall speed and the linear temperature rise and fall speed. Generally speaking, the linear temperature rise and fall speed (average speed per 5 minutes) is 1/2 of the average temperature rise and fall speed of the whole process.
