Analyze the causes of non-refrigeration in the thermal shock test chamber

1. When the thermal shock test chamber is not cooling, you can check the circuit first to see if the compressor is operating normally, and use measurement to test whether the circuit switch is stable. If the switch is unstable, it will also cause the compressor to not work properly, which will also lead to no cooling.

2. You can turn off the main power supply of the equipment, remove part of the cover of the refrigeration system, and check the pipes of each refrigeration system with soapy water to see if bubbles are generated. If bubbles are generated, it means that the pipes are leaking. At this time, we need to repair the leaks. .

3. thermal shock test chamber If the inspection finds that there is no air leakage, then we can check whether the discharge and suction pressures of the compressor unit are normal. If the pressure value is low and the suction pressure value reaches the evacuated state, this is the lack of refrigerant. Added. Then we can touch the compressor's discharge and suction pipes by hand. If the temperature of the discharge pipe is low and the suction pipe is not frosted, this is also caused by insufficient refrigerant. We can check, maintain and maintain the cold and heat shock test chamber used for the refrigerant, so as to avoid failure.
