Anti-freezing type table cooler evaporator manufacturers of industrial water air conditioning table cooler coil condenser Evaporator maintenance 1, often the evaporator leakage detection work. Leakage is a common failure phenomenon of the evaporator, in the process of use should pay attention to frequent leakage detection. Ammonia evaporator leakage, there is an irritating odor, leakage point is not frost. The leak can be checked with phenolphthalein test paper, because ammonia is alkaline, meet phenolphthalein test paper becomes red. With the eye, generally in the evaporator somewhere not frost is usually the leak, but also in the leak with soapy water to find the leak. Freon evaporator leakage check can use halogen lamps and halogen leak detector, can also use soapy water to find leaks. When checking the first eye to see if there is oil on the evaporator tube, because Freon and oil can be mutually soluble, Freon leaks, oil will also seep out of the leak, therefore, where there is…
