Abstract: front page image
(EN)Disclosed is a refrigeration cycle device that is brought into a supercritical state on a high pressure side by the use of a refrigerant that transitions to a supercritical state and that can increase cooling capacity even under overload conditions. The refrigeration cycle device (100) regulates the high pressure-side pressure of the refrigerant which flows through a main refrigerant circuit, by the use of a control device (50) to control a second expansion valve (6) aperture and the heat transfer surface area of a radiator (2).
(FR)L'invention concerne un dispositif de cycle de refroidissement porté à un état supercritique du côté haute pression, lequel met en oeuvre un agent réfrigérant passant à l'état supercritique et lequel permet d'augmenter la capacité de refroidissement même en condition de surcharge. Ce dispositif de cycle de refroidissement (100), par contrôle du degré d'ouverture d'un deuxième détendeur (6) et de la surface de transmission de chaleur d'un organe (2) d'évacuation de la chaleur au moyen d'un dispositif de commande (50), permet de réguler la pression côté haute pression de l'agent réfrigérant s'écoulant dans le circuit principal de refroidissement.
(JA) 超臨界状態に遷移する冷媒を用い、高圧側で超臨界状態となる冷凍サイクル装置において、過負荷条件となったときでも冷房能力を大きくすることが可能な冷凍サイクル装置を提供する。 冷凍サイクル装置100は、制御装置50によって、第2膨張弁6の開度及び放熱器2の伝熱面積を制御することによって、主冷媒回路を流れる冷媒の高圧側圧力を調整している。
