Training Topic: Classification and Market Share of Refrigeration Oil Base Oils

The base oil of refrigeration oil is the core raw material that determines its performance. Currently, in the global refrigeration market, refrigeration oil base oils are mainly divided into 4 categories, with their respective market shares and characteristics as follows: 1. Mineral Oil: It accounts for about 65% of the market, and is the most widely used refrigeration oil base oil at present. Refined from petroleum distillation, it has low cost, is suitable for non-polar refrigerants, and can meet the needs of conventional refrigeration compressors with medium and low loads 2. Polyalphaolefin (PAO): It accounts for about 22% of the market. As a synthetic non-polar base oil, it has better low-temperature fluidity and high-temperature stability than mineral oil. It is suitable for non-polar/weakly polar refrigerants and is mostly used in high-load refrigeration compressors 3. Ester Oil (mainly POE polyester): It accounts for about 10% of the market. It is a synthetic polar base oil, which has excellent compatibility with polar refrigerants such as R32 and R410A, and is mostly used in frequency conversion and environmentally friendly refrigeration systems 4. Other Types (such as PVE ether oil): It accounts for about 3% of the market. This type of base oil has the strongest comprehensive performance, with outstanding low-temperature fluidity and hydrolysis stability, but the cost is relatively high, and it is generally used in special refrigeration working conditions with ultra-high temperature or ultra-low temperature Training Summary The proportion of these 4 types of base oils also reflects the current demand characteristics of the refrigeration industry: the high proportion of mineral oil reflects the popularity of conventional refrigeration scenarios, while the proportion of synthetic base oils is increasing year by year, which also shows that the industry's demand for environmentally friendly and high-load refrigeration systems is growing
