Title (EN) AIR CONDITIONING DEVICE
(FR) DISPOSITIF DE CLIMATISATION
(JA) 空気調和装置
Abstract:
(EN) The purpose of the invention is to increase or decrease the amount of circulating refrigerant that is diverted to an indoor heat exchanger and a heat source-side heat exchanger that is being defrosted by way of increasing or decreasing the degree that a heat source-side flow rate regulating valve is opened while on-defrost is operating, to improve heating performance when a small amount of frost is formed, and to perform defrosting reliably when a large amount of frost is formed. An air conditioning device forms a defrost circuit and forms a heating circuit while on-defrost is operating. In a state where on-defrost is operating, the heat source-side flow rate regulating valve is configured to increase or decrease the amount of refrigerant circulating in either of the defrost circuit or the heating circuit by adjusting the degree the valve is opened.
(FR) L'invention vise à augmenter ou à diminuer la quantité de fluide frigorigène circulant qui est déviée vers un échangeur de chaleur intérieur et un échangeur de chaleur côté source de chaleur qui est dégivré par augmentation ou diminution du degré d’ouverture d’une soupape de régulation de débit côté source de chaleur alors qu’un dégivrage est en cours, pour améliorer la performance de chauffage lorsqu'une faible quantité de givre est formée, et qui permet le dégivrage de manière fiable lorsqu'une grande quantité de givre est formée. Un dispositif de climatisation forme un circuit de dégivrage et forme un circuit de chauffage alors que le dégivrage est en cours. Dans un état où le dégivrage est en cours, la soupape de régulation de débit côté source de chaleur est conçue pour augmenter ou réduire la quantité de fluide frigorigène circulant dans le circuit de dégivrage ou le circuit de chauffage par réglage du degré d'ouverture de la soupape.
(JA) オンデフロスト実行中に熱源側流量調整弁の開度調整によって除霜される熱源側熱交換器と室内側熱交換器に分流する冷媒循環量を増減し、着霜量が少ない場合は暖房能力を向上し、また着霜量が多い場合は除霜を確実に行う。空気調和装置は、オンデフロスト実行時に、デフロスト回路を構成し、かつ、暖房回路を構成し、オンデフロスト実行状態では、熱源側流量調整弁は、開度調整により、デフロスト回路と暖房回路とのどちらかを循環する冷媒量を増減するように構成された。
