Title (EN) REFRIGERATION CYCLE DEVICE AND HEAT SOURCE UNIT
(FR) DISPOSITIF À CYCLE FRIGORIFIQUE ET UNITÉ DE SOURCE DE CHALEUR
(JA) 冷凍サイクル装置および熱源ユニット
Abstract:
(EN) A refrigeration cycle device (2) is provided with: a refrigerant circulation circuit (20) to which a compressor (10), an oil separator (12), a condenser (14), an expansion valve (16), and an evaporator (18) are sequentially connected and through which a refrigerant circulates; an injection flow path (50) to which an opening/closing valve (54) is provided and through which the refrigerant condensed by the condenser (14) is returned to the compressor (10); and an oil return flow path (60) through which refrigerator oil separated by the oil separator (12) is joined to the upstream of the opening/closing valve (54) of the injection flow path (50).
(FR) L'invention concerne un dispositif à cycle frigorifique (2) qui comprend: un circuit de circulation de fluide frigorigène (20) auquel un compresseur (10), un séparateur d'huile (12), un condenseur (14), un détendeur (16), et un évaporateur (18) sont connectés de manière séquentielle et à travers lesquels circule un fluide frigorigène; un trajet d'écoulement d'injection (50) auquel une soupape d'ouverture/fermeture (54) est fourni et à travers lequel le fluide frigorigène condensé par le condenseur (14) est renvoyé au compresseur (10); et un trajet d'écoulement de retour d'huile (60) à travers lequel l'huile pour machine frigorifique séparée par le séparateur d'huile (12) rejoint l'amont de la soupape d'ouverture/fermeture (54) du trajet d'écoulement d'injection (50).
(JA) 冷凍サイクル装置(2)は、圧縮機(10)、油分離器(12)、凝縮器(14)、膨張弁(16)、および蒸発器(18)が順次接続され、冷媒が循環する冷媒循環回路(20)と、凝縮器(14)で凝縮された冷媒を圧縮機(10)に戻す流路であり、開閉弁(54)が設けられたインジェクション流路(50)と、インジェクション流路(50)の開閉弁(54)の上流に、油分離器(12)で分離された冷凍機油を合流させる油戻し流路(60)と、を備えたものである。
