Jieyang preservation library project, the preservation project, Kuhne cold

 Cold cold storage capacity classification: (a) the size of the cold storage capacity is divided into large, medium and small models. Large cold storage refrigeration capacity 10000t above; medium-sized refrigerated cold storage capacity in 1000 ~ 10000t; small refrigerator refrigerated capacity 1000t below. Cold temperature classification: (b) the design temperature refrigeration sub divided into high, medium temperature, low temperature and cryogenic refrigerator four categories. ① general design of high-temperature refrigerated cold temperatures at -2 ℃ to + 8 ℃; ② design temperature refrigerated cold temperatures this -10 ℃ to -23 ℃; ③ low temperature cold storage project in Puning, temperature is generally -23 ℃ to - 30 ℃; ④ ultra quick-freezing temperature is generally -30 ℃ to -80 ℃. Cold one, measuring the supply voltage. 2, measuring three compressor and the motor winding insulation resistance value. 3, the valve opening and closing the case to check the cooling system. 4, after the injection of the liquid filling refrigerant evacuated to a standard amount of filling 70% -80% by weight of the preservation project in Guangzhou, then operation of the compressor, from the low-pressure gas to add enough capacity so far. 5, the first boot after listening to the sound of the compressor is normal to see a condenser, cooling fan is functioning properly, the compressor phase current is stable.
