Title
(EN) POWER SAVING TYPE COMPRESSOR AND REFRIGERATOR WITH THE SAME AND METHOD FOR CONTROLLING THE SAME
(FR) COMPRESSEUR A ECONOMIES D'ENERGIES, REFRIGERATEUR AINSI POURVU, ET PROCEDE DE REGULATION CORRESPONDANT
Abstract
(EN)
The present invention relates to a compressor (5) and a refrigerator with the same, and more particularly, to a power saving type compressor which can prevent unnecessary consumption of a current for the compressor to have high energy efficiency, and a refrigerator with the same and a method for controlling the same, wherein the power saving type compressor includes a main winding and a sub-winding respectively having a main terminal (R) and a sub- terminal (s) main winding and a sub-winding being connected with a common terminal to each other, and a PTC switching unit between a PTC unit connected to the sub-terminal for increasing a starting torque in operation of the compressor and the main terminal, for making selective switching on/off of a power input to the PTC unit.
(FR)
La présente invention concerne un compresseur (5) et un réfrigérateur ainsi équipé. L'invention concerne plus particulièrement un compresseur à économies d'énergies évitant les consommations électriques superflues pour un grand rendement du compresseur, et un réfrigérateur ainsi équipé, ainsi qu'un procédé de régulation correspondant. En l'occurrence, ce compresseur comporte un enroulement principal et un sous-enroulement comportant respectivement une borne principale (R) et un enroulement principal de sous-borne (s) ainsi qu'une sous enroulement raccordé par une borne commune l'un à l'autre, et une unité de commutation à coefficient de température positif entre, d'une part une unité de commutation à coefficient de température positif raccordée à la sous-borne de façon à augmenter le couple de lancement dans le fonctionnement du compresseur, et d'autre part la borne principale, pour faire une commutation sélective en marche/arrêt d'une entrée d'alimentation électrique sur l'unité de commutation à coefficient de température positif.
