How to distinguish the quality of refrigeration compressor unit of constant temperature and humidity test chamber?

2024-09-04

Distinguishing the quality of a constant temperature and humidity test chamber mainly depends on distinguishing the quality of the refrigeration compressor unit to see if it meets the relevant performance of the equipment you have purchased. Its quality directly affects the service life and test results of the constant temperature and humidity test chamber. You can simply judge it from these aspects: appearance, production date, sound, surface temperature of the compressor, etc.

The compressor in a brand-new constant temperature and humidity test chamber generally has a very smooth appearance and bright colors. The welding ports of the input and output pipes are directly welded to the evaporator. If it is rewelded, there will generally be traces of grinding.
There is a nameplate on a new compressor, which is marked with the compressor model, number, production date, power size, etc. We can check them one by one.
When the compressor starts to rotate, as the running time increases, the compressor should emit a clear, uniform and stable running sound, and the sound will gradually decrease.
When the compressor stops, it will not make abnormal sounds.
When the compressor of the constant temperature and humidity test chamber is working, we can also touch its casing with the back of our hand.
The casing will not be very hot. If the above inspections do not meet or if one item does not meet the performance standard, you can directly ask the manufacturer providing the test equipment what the problem is and request a solution.
