  The refrigerant is often used in the chiller refrigeration unit. The refrigerant is indispensable for the refrigeration cycle, and it is indispensable. It plays an important role in the entire chiller. Due to the different physical and chemical properties of various refrigerants, the use and storage of refrigerants are not the same. Here to find out the answer.
   Whenever the refrigerant runs out, immediately close the gas cylinder valve. When checking the system, if the refrigerant is drawn from the series and pressed into the cylinder, it should be sufficiently cooled, and the weight of the injection cylinder must be strictly controlled. It cannot be installed. In sufficient circumstances, it generally does not exceed 60% of the cylinder volume, allowing it to have a certain expansion space at room temperature. In addition, when using halogen lamps for leak detection of the chiller refrigeration system, if the color changes, determine the leakage, immediately remove the suction Mouth to avoid phosgene poisoning.
   At different temperatures, refrigerants have different saturation pressures. At room temperature, some have higher pressures and some have lower pressures. However, no matter what the pressure is, all kinds of refrigerant bottles are pressure vessels, and care must be taken when using them. Various refrigerants have different properties, most of which are explosives. If the cylinder is not checked for corrosion, or if it is suddenly exposed to sunlight or fire, an explosion may occur, and some refrigerants are toxic. Therefore, attention must be paid to the storage, handling and use of refrigerants.
