Title
(EN) HOUSEHOLD APPLIANCE CONTAINING A HEAT TRANSFER FLUID
(FR) APPAREIL DOMESTIQUE CONTENANT UN FLUIDE DE TRANSFERT THERMIQUE
Abstract
(EN)
The invention relates to a household appliance (1) comprising a drying chamber (2) for drying wet articles (3) therein, a process air loop (4) for circulating process air to dry the articles (3) and a heat pump (8, 9, 10, 11, 12). Said heat pump (8, 9, 10, 11, 12) comprises a heat transfer loop (8) containing a heat transfer fluid to be circulated through said heat transfer loop (8), an evaporator heat exchanger (9) for transferring heat from the process air into said heat transfer fluid by evaporating said heat transfer fluid, a liquefier heat exchanger (10) for transferring heat from said heat transfer fluid to the process air by liquefying said heat transfer fluid, a compressor (11) for compressing the heat transfer fluid and driving the heat transfer fluid through said heat transfer loop (8), and a nozzle (12) for decompressing said heat transfer fluid. Further, said heat transfer fluid has a critical temperature above 60°C, a nominal heat of vaporization at boiling point of at least 220 kJ/kg, a GWP index of less than 150 and a lower flammability level of at least 0,1 kg/m3. Preferably, the household appliance (1) is a dryer (1) for drying wet laundry (3).
(FR)
La présente invention concerne un appareil domestique (1) qui comprend une chambre de séchage (2) destinée à sécher des articles humides (3), une boucle d'air de traitement (4) destinée à faire circuler un air de traitement pour sécher les articles (3) et une pompe à chaleur (8, 9, 10, 11, 12). Ladite pompe à chaleur (8, 9, 10, 11, 12) comprend une boucle de transfert thermique (8) qui contient un fluide de transfert thermique devant circuler à travers ladite boucle de transfert thermique (8); un échangeur thermique évaporateur (9) destiné à transférer la chaleur de l'air de traitement audit fluide de transfert thermique, en faisant évaporer ledit fluide de transfert thermique; un échangeur thermique liquéfacteur (10) destiné à transférer la chaleur dudit fluide de transfert thermique à l'air de traitement en liquéfiant ledit fluide de transfert thermique; un compresseur (11) destiné à comprimer le fluide de transfert thermique et entraîner le fluide de transfert thermique à travers ladite boucle de transfert thermique (8); et une buse (12) destinée à décomprimer ledit fluide de transfert thermique. En outre, ledit fluide de transfert thermique a une température critique supérieure à 60°C, une chaleur nominale de vaporisation, à un point d'ébullition, d'au moins 220 kJ/kg, un indice GWP inférieur à 150 et un niveau d'inflammabilité inférieur d'au moins 0,1 kg/m3. De préférence, l'appareil domestique (1) est un sèche-linge (1) pour sécher du linge humide (3).
