Improper management of refrigerant in chillers is extremely dangerous
Refrigerant is an essential substance for the cooling effect of air-cooled chillers, and there are many precautions to be taken during use. Improper management can be very dangerous.
Refrigerant, also known as refrigerant, refrigerant, or snow seed, has different methods of adding refrigerant to different equipment, and the elements of the refrigerant used are also different. Industrial refrigerants are explosive materials with the potential for explosion, so special attention should be paid to their storage.
For the materials used to store refrigerants, it is recommended to choose steel cylinders, which are relatively new. Although some new steel cylinders are used, they should be carefully checked for sealing status, corrosion spots, and if there are corrosion spots, it is recommended to replace them. We cannot be careless in this matter. Negligence ultimately leads to more serious things happening too late.
Also, do not fill the steel cylinder too full in summer, as it is very dangerous. The temperature in summer is particularly high, so it should be placed in a cool place and not exposed to direct sunlight for a long time, otherwise the pressure inside the cylinder will increase. According to the principle of thermal expansion and contraction, the weight of refrigerant injected into the cylinder must be controlled well, and remember not to fill it completely. How much should be installed? Usually, it should not exceed 60% of the cylinder capacity, so even if the temperature rises, there will be room for expansion. In addition to not being exposed to direct sunlight, it is also important to avoid contact with sources of fire and stay away from flammable materials.
Be careful when using it, improper management of refrigerant in air-cooled chillers can be very dangerous. Regardless of the composition or type of refrigerant, the cylinder valve should be immediately closed after use. When using halogen lamps to detect leaks in the refrigeration system of a freezer, if the color changes and the leak point is determined, the suction port should be immediately removed to avoid phosgene poisoning.
