Freezer refers to the compressor used by compression refrigeration, because of its use conditions and compression medium, it is different from the general air compressor. According to the working characteristics of the refrigerator and the specific requirements of the lubricating oil and the deployment of lubricating oil type, the commonly used refrigerants are: freon, ammonia, lithium bromide, methane chloride, etc..
Pour point refers to the oil in the specified test conditions, the cooling sample can flow at the lowest temperature; Freezing point refers to the oil in the specified test conditions, the cooling sample oil surface no longer move when the highest temperature, are expressed in ℃.
The physical significance of pour point is one of the parameters reflecting the low temperature fluidity of oil. The lower the pour point is, the better the low temperature fluidity of oil.
Pour point is a conventional indicator used to measure the fluidity of lubricating oil and other low temperature. The pour point of the same oil is a few degrees higher than the freezing point, which was commonly used in the past and used internationally.
High pour point or freezing point, low temperature fluidity of oil is poor. People can consider the measures to be taken when transporting, storing, receiving and receiving under low temperature conditions according to the level of oil pour point, and can also be used to evaluate the low temperature performance of some oil.
Testing standard: GB/T3535-2006, which is equivalent to ISO 3016-1994
