The high and low temperature test chamber mainly exchanges heat by converting the airflow in the box. In addition, the air inside the box is isolated from the air outside the box and closed.
Since the box is completely enclosed, the moisture in the box is quantitative. From a theoretical point of view, it is impossible to increase the amount of water to form a frost body, then where does this extra moisture come from? During the test, the user opens the cabinet door of the cryogenic chamber, and the cabinet air forms an air exchange with the outside world. The moisture in the air enters the cabinet. Therefore, when using the high-low temperature test box to conduct product testing, it is not allowed to open the door of the box, not only to increase the frost, but also to produce the uncertainty of the test data.
1 , first of all to ensure that the equipment is placed in a well-ventilated place without dust, if not used for a long time, it must be the equipment cover, or placed in a dust-free space.
2 , we must do a good job of regular maintenance, the use of the equipment must be a professional staff, and to do a good job in maintenance records, do not allow the use of only no support, only the situation can not be maintained.
3 , in the continuous summary of maintenance experience, improve the quality of maintenance, to develop a more complete maintenance system, so that self-inspection, mutual understanding, full-time inspection and a joint.
4 , can not start the compressor frequently, the best interval is 15 minutes or more.
