Summary of reasons for non-refrigeration of high and low temperature test chamber

When we use high and low temperature test chambers , it is inevitable that we will encounter such failures, that is, the high and low temperature test chambers are not cooled. So what is the cause of the high and low temperature test chamber not cooling? How to repair and repair?

1. Hardware failure. The hardware that is most likely to cause uncooling is a component such as a compressor or a solenoid valve. Then our users can understand the hardware damage by listening and touching. If the compressor is faulty, the sound of the compressor will be abnormal or not working or the temperature of the compressor itself will be much higher than the normal temperature, and the solenoid valve will be faulty. The user of other refrigeration components is not very well mastered, and the professional maintenance engineer of the instrument should be inspected and analyzed. In addition, damage to the controller and damage to the electronic components of the control refrigeration system may also cause the high and low temperature test chambers not to cool down or cool.

Another kind of hardware failure is when the energy matching of the high and low temperature test chamber is unreasonable. For example, the heating power is installed too much. When the heating element is damaged, the cooling capacity will directly match the heating capacity. Although there is cooling capacity, it is indeed Excessive heating is offset by the amount of heating and the amount of heating is much higher than the amount of cooling, at which point the temperature does not appear to drop.

2, soft faults. The soft fault mainly refers to the controller failure of the high and low temperature test chamber, including the internal parameters, the IS control and the output signal of the control points for controlling the on and off of the solenoid valve. The user of the fault is also not well mastered and needs professional Instrument maintenance engineer on-site inspection analysis.
