Title
(EN) CAPACITY VARYING TYPE ROTARY COMPRESSOR AND REFRIGERATION SYSTEM HAVING THE SAME
(FR) COMPRESSEUR ROTATIF A CAPACITE VARIABLE ET SYSTEME DE REFRIGERATION LE COMPRENANT
Abstract
(EN) A capacity varying type rotary compressor and a refrigeration system having the same. The capacity varying type rotary compressor comprises a casing containing a certain amount of oil and maintaining a discharge pressure state; a motor installed in the casing and generating a driving force; one or more cylinder assembly fixed in the casing, having a compression space for compressing a refrigerant by a rolling piston that performs an orbit motion and a vane that performs a linear motion by contacting the rolling piston, and having a vane pressure chamber formed at a rear side of the vane, for implementing a normal driving as the vane contacts the rolling piston or implementing a saving driving as the vane is separated from the rolling piston; and a mode switching unit for selectively supplying suction pressure or a discharge pressure to the vane pressure chamber of the cylinder assembly according to a driving mode. An installation of pipes can be simplified, a capacity varying ability can be easily controlled even when the compressor is driven, and the valve has less cooling capability loss thereby to enhance a driving efficiency. Furthermore, since the refrigeration system can implement an easy mode switching, comfort and energy saving are enhanced. Also, an interference between the pipes is prevented, thereby minimizing the refrigeration system and enhancing an assembly characteristic. Additionally, since the number of the valves of the refrigeration system is decreased, a production cost is reduced.
(FR) Un compresseur rotatif à capacité variable comprend un carter contenant une certaine quantité d'huile et maintenant un état de pression de décharge ; un moteur installé dans le carter et générant une force d'entraînement ; un ou plusieurs ensembles cylindres fixés dans le carter, possédant un espace de compression pour comprimer un réfrigérant au moyen d'un piston rotatif qui décrit un mouvement orbital et d'une aube qui décrit un mouvement linéaire lorsqu'elle entre en contact avec le piston rotatif, et possédant une chambre sous pression d'aube formée à l'arrière de l'aube, conçue pour mettre en oeuvre un entraînement normal lorsque l'aube vient en contact avec le piston rotatif ou pour mettre en oeuvre un entraînement économique lorsque l'aube est séparée du piston rotatif, et une unité de commutation de mode conçue pour fournir sélectivement une pression d'aspiration ou une pression de décharge dans la chambre à pression de l'aube de l'ensemble cylindre selon le mode d'entraînement. La tuyauterie peut être simplifiée, la caractéristique de capacité variable peut être modulée facilement même lorsque le compresseur est entraîné, et les soupapes présentent une perte de capacité de refroidissement plus faible afin d'améliorer l'efficacité d'entraînement. De plus, étant donné que le système de réfrigération peut mettre en oeuvre une commutation de mode facile, le confort et l'économie d'énergie sont améliorés. Par ailleurs, l'interférence entre les tuyaux est empêchée, ce qui minimise le système de réfrigération et augmente la caractéristique de l'ensemble. Le nombre de soupapes du système de réfrigération étant réduit, le coût de production est réduit aussi.
