How to avoid the problem of icing inside the high and low temperature test chamber

Many people who use high and low temperature test chambers know that when they often do ultra-low temperature testing, they will encounter the freezing of the air-conditioning evaporator in the chamber. This is not surprising, but it has caused great attention. If it is not resolved for a long time, it will affect the operating instructions of the refrigeration compressor and cause damage to the refrigeration compressor.

How to deal with the former to solve the problem of freezing inside the high and low temperature test chamber? We can solve the problem in the following aspects:

1. Check whether the box is sealed. If there is steam leakage, use silicone rubber for sealing.

2. Install heating equipment in the notes of the internal air-conditioning evaporator, and set the timing to perform defrosting.

3. Defrosting is set when the refrigeration unit re uses the high temperature caused by the refrigeration compressor.
