[0033] Prepare the refrigeration oil composition according to the formula shown in Table 1, and test the solubility of the refrigerant in the base oil (under 80°C and 2.5MPa), the two-layer separation temperature, viscosity, stability and lubricity, etc. The results are shown in Table 1 .

[0034] In Table 1, each material is calculated in parts by weight;

[0035] Refrigerant: R290 hydrocarbon-based refrigerant, the amount is relative to the amount of base oil of 100 parts by weight;

[0036] The base oil structure is shown in formula I, R 1 , R 2 and the specific selection of m are shown in Table 1;

[0037] Amine antioxidants: Dioctyldiphenylamine;

[0038] Phenolic antioxidant: 2,6-di-tert-butyl-p-cresol;

[0039] The test methods for each performance parameter are as follows:

[0040] Two-layer separation temperature (°C): Fill base oil and refrigerant (the oil content is 15% by weight, 20% by weight, 25% by weight, 30% by weight, 35% by weight) % by weight, 40% by...

Abstract

The invention relates to the field of refrigeration equipment and discloses refrigerant oil composition and an application thereof. The refrigerant oil composition comprises base oil and a refrigerant, wherein the refrigerant is propane; the base oil contains a compound shown as formula I in the description, in the formula I, R1 is H, R2 is H or C1-C18 alkyl, and m is an integer larger than or equal to 1. The invention further discloses a compressor with the refrigerant oil composition serving as a circulating cooling liquid system as well as a refrigerating circulating device. The base oil and the refrigerant propane have good solubility, the lubricity is good, so that sufficient cooling can be also realized even when the dosage of the refrigerant is lower, and the safety is guaranteed while the cooling effect is guaranteed.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration oil composition and its application. Background technique [0002] In recent years, for the purpose of protecting the earth's environment, refrigerants used in refrigeration cycle systems have begun to shift from traditional Freon R22 and hydrofluorocarbons HFCs to natural refrigerants, especially hydrocarbon-based refrigerants that are natural refrigerants. From the viewpoint of low global warming coefficient GWP, propane R290 refrigerant has attracted more and more attention. [0003] However, when hydrocarbon-based refrigerants are used in compression refrigerators, when the existing mineral oil, alkylbenzene, and synthetic POE oil are used as lubricating oils, since the base oil and the refrigerant are completely dissolved, the viscosity of the base oil is reduced and the lubricating oil is reduced. As a result, the wear resistance and sealing performan...
