However, the new refrigerant does not have an excellent heat exchange rate compared to Freon, and the conventional compressor has the same compression.

Abstract

L'invention concerne un compresseur à spirale capable de contribuer à la réduction de la totalité de la taille et du poids de celui-ci et présentant une excellente durabilité et une excellente fiabilité. Le compresseur à spirale peut être actionné à ultra haute vitesse en appliquant un nouveau réfrigérant au compresseur à spirale. Dans le compresseur à spirale, le substrat d'un anneau d'Oldham (107) est composé d'un alliage d'aluminium, et une couche DLC dure est formée sur la surface du substrat par l'intermédiaire de couches de base qui présentent une excellente adhésivité et compensent la dureté et, par conséquent, le poids de l'anneau d'Oldham est réduit d'environ 1/3, et l'adhésion et l'abrasion entre des éléments coulissants sont empêchées afin d'améliorer la résistance à l'abrasion et de réduire le coefficient de frottement et, en outre, la masse d'inertie d'un système de rotation est réduite. En outre, une spirale rotative (101) comprend une structure de matériau similaire à la structure de l'anneau d'Oldham et, par conséquent, la masse excentrique d'un système de rotation est réduite. Ainsi, la charge de couple d'un moteur (100) peut être extrêmement réduite, la totalité du poids et de la taille peut être réduite, et la durabilité et la fiabilité sont excellentes. Le compresseur à spirale peut être actionné à ultra haute vitesse en appliquant un nouveau réfrigérant au compresseur à spirale, et une performance de compression similaire à celle obtenue lorsque du chlorofluorocarbure est utilisé peut être obtenue.
