What should be done when the refrigerated display cabinet is flooded

The refrigeration system of refrigerated display cabinet may enter moisture due to improper operation, resulting in ice blocking and affecting the normal work of the refrigeration system.

Treatment method of refrigerating display cabinet after water entering into the refrigeration system:

One. Reasons:

The first step is to check the cause of water entering the refrigeration system and what causes water entering the refrigeration system.

Two. Sectional blowout:

Water can be first blown with an air compressor (saving), until no water fog out. Then blow with high pressure, which can be heated at the same time (heating is forbidden in cylinders). Due to the complexity of refrigerant pipeline, it is possible to use welding in some parts of the pipeline to separate and blow. Heat drying, for capillary, thermal valve, compressor and other small parts can choose the oven drying. The refrigerated oil must be replaced after the compressor is dried with water

Three. Vacuum drying:

Restore the pipeline and connect the vacuum pump for vacuum drying after keeping pressure and ensuring air tightness. (the drying filter bucket must be added in the front of the vacuum pump to avoid excessive water and air in the vacuum pump) in the vacuum drying can heat the part of the pipeline where water is easy to store, the time is determined according to the site.

Four. Commissioning and operation:

Make sure that the water in the basic elimination of clean. Connect the external drying filter bucket in the center and change the desiccant after 5 minutes of operation. At the same time, observe the operating parameters of the unit and pay attention to the running sound of the compressor. If there is a pressure difference of more than 0.5 kg before and after the drying filter cooling, valve frosting and air return filter, stop the machine immediately. (desiccant: calcium chloride drying particles have large water absorption capacity, and can be used in the case of excessive water at the beginning. After the desiccant change into color silica gel, 24 hours of operation to ensure that the color silica gel maintains the original color

Five. completion:

Remove the refrigerant line from the dry filter barrel and restore it. Check supplemental refrigerant quantity. Start the machine to check the normal operation parameters.
