In the process of refrigerant replacement,it is necessary to research on the dispersion and stability of nano-particles in the mineral-base refrigeration oil to solve the miscibility problem between the HFCs refrigerant and the mineral refrigeration oil.

The impact of n-TiO2(a) to the viscosity of mineral refrigeration oil was analyzed by way of the molecule momentum theory, and the mathematic model is given to forecast the viscosity about the n-TiO2(a)/mineral oil.

Development of new type refrigerator oil for refrigerant R600a

Influence analysis of nanometer refrigerator oil on HFC134a saturation pressure

At the laboratory,according to the German DIN51503 VG46 refrigerator oil standard,with the craft of high pressure hydrorefining(catalyst: RN-1)-high pressure hydrodewaxing(catalyst: RDW-1)-cutting distillates,the suitable refrigerator oil which can meet the demand of international market was developed on 100 mL small hydrogenation experimental apparatus by taking Karamay naphthenic VGO No.

Preparations of new type automobile air-conditioning lubricating oils;

By analyzing on the inside program of the experimental rig,the test process and the glass electrode, the results about the total acid number(TAN)of refrigeration lubricant that was on the high side is discussed in this paper.

Therefore it was significant to study on the low cost and environmental refrigerant lubricant matching HFC-134a.
