(FR) UNITÉ DE CLIMATISATION
Abstract
(EN) A first flow switching device (A) causes part of a refrigerant discharged from an injection compressor (1) to flow through a first bypass pipe (21) and be supplied to an outdoor heat exchanger (9b) targeting for defrosting. A second flow switching device (B) causes part of the refrigerant supplied to the outdoor heat exchanger (9b) targeting for defrosting to enter a second bypass pipe (31).
(FR) L'invention porte sur une unité de climatisation. Une partie d'un fluide frigorigène refoulé par un compresseur à injection (1) est contrainte de passer dans un premier tube de dérivation (21) au moyen d'un premier dispositif d'aiguillage de trajet d'écoulement (A) et est fourni à un échangeur de chaleur externe (9b) à dégivrer, et une partie du fluide frigorigène fourni à l'échangeur de chaleur externe (9b) à dégivrer est contrainte de passer dans un second tube de dérivation (31) sous l'action d'un second dispositif d'aiguillage de trajet d'écoulement (B).
