Title
(EN) REFRIGERATION APPLIANCE AND CONTROL METHOD FOR A REFRIGERATION APPLIANCE
(FR) APPAREIL FRIGORIFIQUE MÉNAGER ET PROCÉDÉ DE COMMANDE ASSOCIÉ
Abstract
(EN)
The present invention provides a control method for a refrigerating appliance (100). The control method includes: running a compressor (4) and a fan (61, 81) to cool a storage space, and adjusting a rotating speed of the fan (61, 81) in association with a temperature of the storage space or adjusting the rotating speed of the fan (61, 81) in association with a rotating speed of the compressor (4). In this way, during refrigeration in the storage space, along with a temperature change of the storage space, a cold energy requirement of the storage space also changes, and correspondingly, the rotating speed of the compressor (4) may also change, so as to adjust the rotating speed of the fan (61, 81) based on a rotating speed change of the compressor (4), thereby causing the rotating speed of the fan (61, 81) to basically match the cold energy requirement of the storage space in real time.

La présente invention concerne un procédé de commande destiné à un appareil frigorifique ménager (100). Le procédé de commande consiste : à faire fonctionner un compresseur (4) et un ventilateur (61, 81) afin de refroidir un espace de stockage, et à régler une vitesse de rotation du ventilateur (61, 81) conjointement avec une température de l'espace de stockage, ou à régler la vitesse de rotation du ventilateur (61, 81) conjointement avec une vitesse de rotation du compresseur (4). De cette manière, pendant la réfrigération dans l'espace de stockage, conjointement avec une variation de la température de l'espace de stockage, le besoin d'énergie froide de l'espace de stockage varie également, et, de la même façon, la vitesse de rotation du compresseur (4) peut aussi varier, de façon à régler la vitesse de rotation du ventilateur (61, 81) en fonction d'une variation de la vitesse de rotation du compresseur (4), amenant ainsi la vitesse de rotation du ventilateur (61, 81) à correspondre essentiellement au besoin d'énergie froide de l'espace de stockage en temps réel.
