Abstract
A binary composition of 2,3,3,3-tetrafluoropropene and of ammonia, and also to the use thereof, in particular as a heat transfer fluid.
Claims20
A refrigerant composition comprising:
- optionally, an additive selected from the group consisting of surface active agents, stabilizers, tracers, fluorescent agents, odorants, and solubilizing agents;
- optionally, a lubricant;
- and
- an azeotrope-like composition, the azeotrope-like composition consisting of:
- from 20 to 60 wt % ammonia;
- and
- from 40 to 80 wt % HFO1234yf,
- wherein the azeotrope-like composition, at constant temperature of 5° C., exhibits a pressure of the saturated liquid and a pressure of the saturated vapor which differ by 10% or less.
