Manufacturers go take the appropriate tools. In this way, you can save time with each other. Here are two relatively simple temperature and humidity chamber cascade refrigeration system fault diagnosis and inspection methods. For your reference. Symptom screening method Refrigerant excessive temperature and humidity chamber Annotation much a part of the refrigerant) temperature at the compressor inlet suction pipe frosting 2) the inside temperature can not reach the specified temperature specification 3) High temperature compressor has "wheezes" sound 4) low temperature Refrigerant compressors can not start too low temperature and humidity chamber part too Refrigerant 1) inside temperature should be less than the temperature drop 2) Filling quantity particularly large, cold starting off frequently thermostat 3) low temperature portion exposed outside the box and expander suction tube connecting pipe freezing parts of abnormal phenomenon 4) pressure higher than normal after the input current temperature and humidity chamber after three shun the company can achieve the maintenance of technical standards: Temperature Test Range (0 ℃, -20 ℃, -40 ℃, -70 ℃) ~ +150 ℃ Humidity 30 ~ 98% RH fluctuations / uniformity of ± 0.5 ℃ / ± 2 ℃ humidity bias +2, -3% RH Heating time 1 ℃ ~ maintenance projects 3 ℃ / 35min cooling time of 0.7 ℃ ~ 1 ℃ / 40min Shenzhen Shun Detection Instrument Co. offers three are: Humidity Chamber, environmental chambers, thermal shock chambers, UV aging box, xenon lamp aging chamber, chamber, chilling cold test machine around, yellowing resistance aging box, air ventilation aging chamber, salt spray chambers, ovens and other environmental class testing equipment.
