Title (EN) REFRIGERATOR WITH AN IMPROVED DEFROST CIRCUIT AND METHOD OF CONTROLLING THE REFRIGERATOR
(FR) RÉFRIGÉRATEUR AYANT UN CIRCUIT DE DÉGIVRAGE AMÉLIORÉ, ET PROCÉDÉ DE COMMANDE DU RÉFRIGÉRATEUR
Abstract:
(EN) The present invention relates to a refrigerator comprising: a refrigeration circuit (14) which includes: a compressor (2), a condenser (3), a first capillary (4), a freezer evaporator (5) and a fresh food evaporator (6) which are serially arranged and fluidly connected to one another by respective lines for circulating a refrigerant, a defrost circuit (15) which includes a bypass line (7) which fluidly connects the output of the compressor (2) with the input of the freezer evaporator (5), and a first valve unit (8) for respectively controlling a convey of the refrigerant output from the compressor (2) to an input of the condenser (3) and to the bypass line (7) and a control unit for controlling the refrigeration circuit (14) and the defrost circuit (15), wherein the control unit has a defrost mode and a normal refrigeration mode.
(FR) La présente invention concerne un réfrigérateur comprenant : un circuit de réfrigération (14) qui comprend : un compresseur (2), un condensateur (3), un premier capillaire (4), un évaporateur de congélateur (5) et un évaporateur d'aliment frais (6) qui sont disposés en série et reliés fluidiquement l'un à l'autre par des conduites respectives pour faire circuler un réfrigérant, un circuit de dégivrage (15) qui comprend une conduite de dérivation (7) qui relie fluidiquement la sortie du compresseur (2) à l'entrée de l'évaporateur de congélateur (5), et une première unité de valve (8) pour commander respectivement un transport du réfrigérant du compresseur (2) à une entrée du condensateur (3) et à la conduite de dérivation (7), et une unité de commande pour commander le circuit de réfrigération (14) et le circuit de dégivrage (15), l'unité de commande ayant un mode de dégivrage et un mode de réfrigération normale.
