IIIWuhan walk-in constant temperature and humidity test roomCharging method of refrigerant:
There are two methods for fluorine filling in split refrigeration equipment: high-pressure liquid refrigerant filling and low-pressure gas refrigerant filling. The method of high-pressure liquid refrigerant filling is often used for refrigerant filling during the production process of refrigeration equipment or for refilling refrigerant after major repairs of large air conditioning units. The method of low-pressure gas refrigerant charging is often used for supplementary operations of large refrigeration equipment or refrigerant refilling of general household refrigeration equipment. The charging operation method for split type refrigeration equipment is as follows:
(1) Method of filling refrigerant from the high-pressure side of refrigeration equipment (weighing method)
(2) Method of filling refrigerant from the low-pressure side of refrigeration equipment
4Wuhan walk-in constant temperature and humidity test roomEnvironmental conditions:
Temperature: 5 ℃~+35 ℃ (average temperature within 24 hours ≤ 28 ℃);
