Treatment of refrigeration failure of Shanghai high and low temperature test chamber

The maintenance of test equipment is more important to its service life and test effect, we should do some daily care for it.

Under normal circumstances, the high and low temperature test chamber should be placed in an environment with a temperature of 8 ℃ ~ 28 ℃, the laboratory does not have this condition, it must be equipped with an appropriate air conditioner. Daily maintenance and maintenance should be adhered to, and the condenser should be cleaned every three months. If the compressor uses air cooling, the condenser fan should be regularly repaired and the condenser should be decontaminated and dedusted to ensure good ventilation and heat exchange performance.

For compressors using water cooling, in addition to ensuring the inlet water pressure and inlet water temperature, the corresponding flow rate must also be guaranteed, and the inside of the condenser should be cleaned and descaled regularly to obtain its continuous heat exchange performance.

If the refrigerant in the compressor is not tested for a long time, it should be stored in the storage tank to prevent it from corroding the refrigeration components.
