Abstract
(EN)
A refrigerant circulating system, relating to the field of air conditioners, and being used for optimizing the effect of cooling an oil-less bearing (110). The refrigerant circulating system comprises a compressor (1), a first refrigerant flow path (2), and a second refrigerant flow path (3). The compressor (1) comprises a bearing cavity (111) and a bearing (110) provided in the bearing cavity (111); the first refrigerant flow path (2) is in communication with the bearing cavity (111) and is configured to cool the bearing (110); and the second refrigerant flow path (3) exchanges heat with the first refrigerant flow path (2) so as to cool a refrigerant in the first refrigerant flow path (2). According to the technical solution, supercooling of the refrigerant of the bearing (110) is implemented, so that the temperature of the refrigerant used for cooling the bearing (110) is low, the cooling effect of the bearing (110) is optimized, and the problem that heat is accumulated when the oil-free bearing (110) works is solved.

La présente invention se rapporte au domaine des climatiseurs et concerne un système de circulation de fluide frigorigène qui est utilisé pour optimiser l'effet de refroidissement d'un coussinet auto-lubrifiant (110). Le système de circulation de fluide frigorigène comprend un compresseur (1), un premier trajet d'écoulement de fluide frigorigène (2) et un second trajet d'écoulement de fluide frigorigène (3). Le compresseur (1) comprend une cavité de coussinet (111) et un coussinet (110) disposé dans la cavité de coussinet (111); le premier trajet d'écoulement de fluide frigorigène (2) est en communication avec la cavité de coussinet (111) et est configuré pour refroidir le coussinet (110); et le second trajet d'écoulement de fluide frigorigène (3) échange de la chaleur avec le premier trajet d'écoulement de fluide frigorigène (2) de façon à refroidir un fluide frigorigène dans le premier trajet d'écoulement de fluide frigorigène (2). Selon la solution technique, la surfusion du fluide frigorigène du coussinet (110) est réalisée, de sorte que la température du fluide frigorigène utilisé pour refroidir le coussinet (110) soit faible, l'effet de refroidissement du coussinet (110) est optimisé, et le problème selon lequel la chaleur est accumulée lorsque le coussinet auto-lubrifiant (110) fonctionne est résolu.
