There are three common types of high and low temperature test chamber controllers: 1.
Software failure 2.
Compressor failure 3.
Hardware failure 1.
Soft failure
.
Soft fault mainly refers to the fault of the controller of the high and low temperature test box, including internal parameters, IS control and output signals of each control point that controls the on-off of the solenoid valve
.
2.
System failure
.
System failure refers to a problem with the initial design of the refrigeration system, and also includes refrigerant leakage caused by the high and low temperature test chamber not cooling down.
Caused by poor workmanship and other reasons
.
3.
Hardware failure
.
Among them, there are hardware compressors, solenoid valves and other cooling components that may cause no cooling
.
Then our users can roughly understand what hardware damage is by listening and touching.
If it is a compressor failure, the sound of the compressor will be abnormal or it will not start or the temperature of the compressor itself is much higher than usual, and the solenoid valve failure and The failure of other refrigeration components is not very easy for users to grasp
.
In addition, the damage of the controller and the damage of the electronic parts that control the refrigeration system may also cause the phenomenon that the high and low temperature test chamber does not cool down and does not cool down
.
There is also a hardware failure encountered during the maintenance of the high and low temperature test box.
When the energy matching of the high and low temperature test box is unreasonable, for example, the heating power is installed too large, when the heating element is damaged, it will directly lead to the inconsistency between the cooling capacity and the heating capacity.
Matching, although there is cooling capacity, it is indeed offset by the excessive heating capacity and the heating capacity is much higher than the cooling capacity, and the temperature does not seem to drop at this time
