Definitions

  • the compressor also includes a rotating shaft and a suction chamber.
  • the rotating shaft is arranged inside the casing and extends along the height direction of the casing.
  • the first scroll is connected with the rotating shaft, and can perform rotary motion under the driving of the rotating shaft, and then cooperate with the second scroll to compress the medium.
  • a suction chamber is also formed between the first scroll and the second scroll, and the pressure chamber communicates with the suction chamber and the discharge chamber at the same time.
  • the suction chamber sucks the medium, the medium in the suction chamber enters the intermediate pressure chamber to be compressed, the compressed medium enters the discharge chamber, and finally discharges the compressor.
  • the compressor is a scroll compressor.
  • the requirements for the sealing gasket can be effectively reduced, thereby greatly reducing the design and assembly difficulty of the compressor, and reducing the cost of the compressor.

Abstract

Compresseur et dispositif de réfrigération. Le compresseur comprend : un ensemble plaque à spirale comprenant une chambre de pression (106) ; un élément de contre-pression (108) raccordé à l'ensemble plaque à spirale, et une cavité d'évacuation est formée sur un côté de l'élément de contre-pression (108) à distance de l'ensemble plaque à spirale ; un premier passage (110), disposé sur l'élément de contre-pression (108), et le premier passage (110) est en communication avec la chambre de pression (106) et la cavité d'évacuation ; un commutateur de dérivation (112), disposé à l'intérieur du premier passage (110) et configuré pour communiquer ou fermer le premier passage (110). En utilisant le commutateur de dérivation (112) pour commander l'ouverture ou la fermeture du premier passage (110), la quantité de milieu comprimé dans la chambre de pression (106) peut être ajustée de manière flexible, de sorte que la quantité de milieu comprimé correspond à la demande réelle, ce qui permet d'améliorer l'adaptabilité du compresseur.
