Lab Companion|Why do Thermal Shock Test Chambers Need Defrosting

Frost is the result of rapid cooling and crystallization of water in the air when it is exposed to cold air. The thick frost is easy to become thick ice. In the north, the car is prone to frost in the winter, and thermal shock test chambers are also prone to frost after dozens of cycles of shock test, and it is necessary to shut down for defrost work, otherwise the refrigeration function of the energy storage component itself will be affected.

After understanding why should defrost, I guess you also want to know how frost comes about in thermal shock test chamber and how to remove frost.

Let's start with how frost comes about! The frost in thermal shock test chambers is mainly on the energy storage component in the pre-cooling area, which will absorb water during the execution of work. When the energy storage component is used for refrigeration, frost or icing will occur due to low temperature with the superposition of water.

So how do you defrost it? Select the quality equipment of powerful manufacturer, and make four Settings before the shock test:

1, Automatic defrosting Settings

Defrosting start conditions can be set according to the required test content, such as defrosting once every 100 tests, or according to the required time, or defrosting mode can be turned off.

2, Defrosting times Settings

The required number or time can be set with the number or time of the program done in the program.

3. Temperature as the end of defrost Settings

Set the required defrosting temperature, the higher the temperature, the longer the defrosting time, but the better the defrosting effect.

4. Defrosting delay time Settings

When the set defrosting temperature arrives, the defrosting delay time begins to calculate, and it is generally recommended to set it to 5 to 10 minutes.

Thermal shock test chambers of Lab Companion are divided into two zone thermal shock test chambers(TS2) and three zone thermal shock test chambers(TS3), with automatic defrosting function, the defrosting frequency has been set before the factory, and it will automatically defrost when it reaches a certain number of cycles. If the customer has their own defrosting frequency requirements, they can modify the number of cycles or time in the defrosting Settings of the device control system.
