I. About the refrigeration industry

Refrigeration technology is a scientific and technological field widely used in sectors of national economic development. It has a history of over 100 years since the mid-19th century and has been applied in fields' such as air conditioning, food refrigeration, medical treatment, and'daily life.

Due to technological advancements, the refrigeration industry has adopted refrigerants such as ammonia, carbon dioxide, chloroform, chloroethane, sulfur dioxide, and isobutane. In recent years, due to environmental requirements, the refrigeration industry has successively introduced alternative refrigerants. The adoption of alternative refrigerants has further promoted the development of synthetic refrigeration oil, requiring the development of different refrigeration oils for different refrigerants. China has developed multiple types of refrigeration oils and will gradually align with the world.

Due to differences in degree of refrigeration or environmental regulations, compressor manufacturers use different refrigerants, resulting in individualized differences in refrigeration oil. Ordinary mineral oil is naturally formed and is not applies to molecular structure design, making.it difficult to meet personalized needs. However, being suitable for molecular design is precisely the advantage of synthetic oils, so synthetic oils are widely used in various refrigeration categories.

The overall price of similar products abroad is relatively high. Due to geographical advantages, domestication of imported brands can reduce costs, so cooperation with corresponding refrigeration equipment manufacturers and OEM level communication is the mainstream of development.

The main types of refrigeration oil currently used in China are:

\bullet Refrigerator oil for HFC refrigerant * Refrigeration oil for CO2 refrigerant * Refrigeration oil for hydrocarbon refrigerants \blacktriangle Refrigeration oil for ammonia refrigerant * Refrigerator oil for HCFC refrigerant

There is an obvious trend of global air conditioner production capacity shifting to China. Currently, China's air conditioner output accounts for more than 70% ofthe global output, with the improvement of domestic consumption level, the domestic air conditioner market is expanding very rapidly. The data shows that the ratio of domestic and foreign sales of domestically produced air conditioners is 47:53, while exports are basically on par with domestic sales. According to data from the National Bureau of Statistics, the cumulative production of room air conditioners and refrigerators in China in 2015 was 142,004,000 sets and 79,928,000 sets, respectively, providing potential for development for synthetic refrigeration oil. At the national level, environmental protection requirements will become increasingly strict, and the replacement of R22 in China has become an irreversible trend, which will bring a broad space for the development of synthetic refrigerated oil, but also bring new challenges to the refrigeration industry.

I. Refrigeration system and oil requirements

The refrigeration system generally consists of compressor, condenser, expansion valve, and evaporator system components. Industrial refrigeration air conditioner generally has an independent oil separator, and the system is relatively large, usually maintained by a dedicated person. Small refrigeration systems such as household air conditioners are relatively simple, but require high reliability and long service life without maintenance.

The main function of refrigeration oil in the refrigeration system is to cool the compressor, reduce friction losses, prevent wear, cool the compressor, dissipate the heat generated by compression and friction, and seal the piston (rotor), cylinder, and compressor shaft seal to prevent refrigerant leakage. These performance requirements determine the physical and chemical properties of refrigeration oil and the selection of oil products, with specific requirements including the following aspects:

* Suitable viscosity and good viscosity-temperature performance
* High thermal and chemical stability when in contact with refrigerants
* Suitable solubility with refrigerant
* Excellent lubricity
* Low water content
* High compatibility with materials

From the above requirements, it can be seen that the lubrication requirements of refrigeration systems are different from general mechanical lubrication requirements. Lubrication is only the most basic characteristic of refrigeration oil, and the more important characteristic is the compatibility performance with refrigerant. Many lubricant companies lack awareness of this, with a few types of products for most of the refrigerants, objectively speaking, the versatility has increased, but for a specific refrigeration equipment, more or less problems were caused, so that the user requirements are not satisfied. This series of refrigeration oil products fully consider the above requirements to match the refrigeration system in a targeted manner.

IMI. Overview of the uses of refrigeration oil

Refrigeration oil is mainly classified according to its solubility with refrigerants, which is also an important reference for the selection of oil in the industry.
