Tetrafluoropropene-based composition
Abstract:
A composition including between 4 and 6 wt. % of difluoromethane, between 2.5 and 3.5 wt. % of pentafluoroethane, and between 91 and 93.5 wt. % of tetrafluoropropene. The use of the composition as replacement for R404A, R452A, R22, R134a, R245fa, R152a, R422, R502, R407A, R407F, R407C, R1234yf or R1234ze. A heat-transfer composition including the composition and at least one additive chosen from nanoparticles, stabilizing agents, surfactants, tracing agents, fluorescent agents, odorous agents, lubricants, and solubilizing agents.
