Problems solved by technology

The preparation methods must use mechanical stirring and disturbance to mix the refrigerant, or add surfactants to form microemulsions, which are difficult to evenly distribute in the two-phase system, and must be continuously applied external stirring or circulation even when additives are added. To promote the mixing of the two phases, the presence or absence and continuity of this external force greatly affects the mixing degree of the two phases, which limits the compatibility between the refrigerant and the lubricating oil, thus affecting the heat transfer performance of the refrigerant and other properties
In addition, the external mechanical shear force, electromagnetic field and ultrasonic wave have greatly increased equipment investment and energy consumption.

Description

technical field [0001] The invention relates to the field of refrigerants, in particular to a refrigerant added with an amide compatibilizer and a preparation method thereof. Background technique [0002] As with any replacement material associated with refrigeration compositions, these materials must be compatible with the lubricant employed in the compressor. Unfortunately, conventionally used lubricants, including, for example, mineral oils, alkylbenzenes, or polyU-olefins, etc., are relatively insoluble and / or immiscible with many non-chlorinated refrigerant fluids. In order to have a refrigeration fluid-lubricant combination that works effectively in compression refrigeration, air conditioning or heat pump systems, the lubricant must be sufficiently soluble in the refrigeration liquid over a wide range of operating temperatures. This solubility reduces the viscosity of the lubricant and allows it to flow through the system more easily. In the absence of this solubilit...
