摘要:
The invention relates to the use of 1,1,1,2-tetrafluoroethane for increasing the miscibility of 2,3,3,3-tetrafluoropropene with a lubricating oil, and in particular with a polyalkylene glycol oil. In this regard, the invention provides heat-transfer compositions and also equipment and processes using these compositions.
摘要:
The invention relates to a composition comprising: a heat-transfer fluid comprising from 15% to 30% ammonia and from 70% to 85% 2,3,3,3-tetrafluoropropene; and a lubricant oil comprising a polyalkylene glycol. The invention also relates to the use of ammonia for increasing the miscibility of 2,3,3,3-tetrafluoropropene with the polyalkylene glycol, and vice versa.
