Abstract (en)
[origin: US2013186114A1] 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.
