Résumé

ECP744 is a near azeotrope which shows promising improvements in system efficiency compared to pure R744, whilst also operating at significantly lower pressures. It is considered to be particularly applicable to vehicle air conditioning equipment. The improvement in efficiency is a significant benefit, but the main commercial benefit arises from the reduced pressure (compared to R744). Since the major problem for R744 refrigeration systems is the high pressure which increases leakage despite the use of considerably more aluminium material for the equipment. The use of lower pressure ECP744 refrigerant will minimise this problem, reducing leakage and the weight of aluminium required. Furthermore, it is understood that the CO2 content of ECP744 is sufficiently diluted to overcome the US EPA toxicity objections to the use of R744 in MAC applications.
