Abstract
(EN) A portion of coolant discharged from an injection compressor (1) is made to pass through a first bypass pipe (21) by means of a first flow path switchover device (A) and supplied to an external heat exchanger (9b) to be defrosted, and a portion of the coolant supplied to the external heat exchanger (9b) to be defrosted is made to flow into a second bypass pipe (31) by means of a second flow path switchover device (B).
(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).
(JA)  第1の流路切替装置Aにより、インジェクション式圧縮機1から吐出された冷媒の一部を第1のバイパス配管21を通過させ、デフロスト対象の室外熱交換器9bに供給し、第2の流路切替装置Bにより、デフロスト対象の室外熱交換器9bに供給された冷媒の一部を第2のバイパス配管31に流入させる。
