DuPont "encouraged" by MAC refrigerant tests

DUPONT'S proposed HFC-based, refrigerant replacement for automotive air conditioning has a GWP of just 40 and will be a direct replacement for R134a, according to new information released by the company.
Designated DP-1, the new refrigerant is a response to the forthcoming European F-gas regulations which will phase-out R134a from car ac systems.

As well as having a zero ODP, DP-1 is non-flammable and is said to have so far performed well in critical tests involving thermal stability, materials compatibility, lubricant miscibility and toxicity.
A two component blend, DP-1's pressure/temperature profile is said to be very similar to R134a, thus avoiding the high pressures possessed by its 'natural' competitor CO2. Temperature glide is said to be similar to R407C.
Mark Baunchalk, global business manager, DuPont Refrigerants. 'We are very encouraged by this initial testing because all indications are that DP-1 will be compatible with conventional 134a MAC system technology and, unlike other alternatives such as CO2, will have the potential to enable a cost effective global transition across the entire MAC industry.'
