(EN) WORKING FLUID FOR HEAT CYCLE AND HEAT CYCLE SYSTEM
(FR) FLUIDE MOTEUR POUR CYCLE DE CHAUFFAGE, ET SYSTÈME DE CYCLE DE CHAUFFAGE
Abstract
(EN)
To provide a working medium for heat cycle which has inflammability suppressed, which has less influence over the ozone layer, which has less influence over global warming and which provides a heat cycle system excellent in the cycle performance (efficiency), and a heat cycle system whereby safety is secured and which is excellent in the cycle performance (efficiency). A working medium for heat cycle comprising 1,1-dichloro-2,3,3,3tetrafluoropropene is employed for a heat cycle system (such as a Rankine cycle system, a heat pump cycle system, a refrigerating cycle system 10 or a heat transport system).

(FR)
L'invention fournit : un fluide moteur pour cycle de chauffage qui présente des caractéristiques de combustion régulées, un faible impact sur la couche d'ozone et sur le réchauffement de la planète, et qui confère un système de cycle de chauffage dont les performances de cycle (rendement) sont excellentes; et ledit système de cycle de chauffage dont la sécurité est assurée, et dont les performances de cycle (rendement) sont excellentes. Ce fluide moteur pour cycle de chauffage qui contient un 1,1-dichloro-2,3,3,3-tétrafluoropropène, est mis en œuvre dans un système de cycle de chauffage (système de cycle de Rankine, système de cycle de pompe à chaleur, système de cycle de refroidissement (10), système de transfert de chaleur, ou similaire).
