Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE DE RÉFRIGÉRATION
(JA) 冷凍サイクル装置
Abstract:
(EN) This refrigeration cycle device is provided with pressure pulsation reduction units (15b, 15c, 15d) that reduce pressure pulsation of a refrigerant in a gas-phase refrigerant path (15). One example of the pressure pulsation reductions units is a muffler (15b) that increases the cross-sectional area of the gas-phase refrigerant path and that is arranged between a hose (15a) and a differential pressure valve (16) in the gas-phase refrigerant path (15). Other examples of the pressure pulsation reduction units include resonators (15c, 15d) that form a resonance space and that are connected between the hose (15a) and an intermediate pressure port (11b) in the gas-phase refrigerant path (15).
(FR) L'invention porte sur un dispositif à cycle de réfrigération pourvu d'unités de réduction de pulsation de pression (15b, 15c, 15d) réduisant la pulsation de pression d'un réfrigérant dans un trajet de réfrigérant en phase gazeuse (15). Comme exemple d'unités de réduction de pulsation de pression, un silencieux (15b) qui augmente la surface de section transversale du trajet de réfrigérant en phase gazeuse et qui est agencé entre un tuyau (15a) et une soupape de pression différentielle (16) dans le trajet de réfrigérant en phase gazeuse (15). D'autres exemples des unités de réduction de pulsation de pression comprennent des résonateurs (15c, 15d) qui forment un espace de résonance et qui sont connectés entre le tuyau (15a) et un orifice de pression intermédiaire (11b) dans le trajet de réfrigérant en phase gazeuse (15).
(JA) 気相冷媒通路(15)における冷媒の圧力脈動を低減する圧力脈動低減部(15b、15c、15d)を備える。例えば、圧力脈動低減部は、気相冷媒通路の断面積を拡大させるマフラ(15b)であり、気相冷媒通路(15)のうちホース(15a)と差圧弁(16)との間に配置されている。例えば、圧力脈動低減部は、共鳴空間を形成するレゾネータ(15c、15d)であり、気相冷媒通路(15)のうちホース(15a)と中間圧ポート(11b)との間に接続されている。
