Abstract
(EN) This air conditioner (1000) comprises: a refrigerant circuit (100) in which a compressor (1), a switching valve (2), a cascade heat exchanger (3), an expansion valve (4), and an outdoor heat exchanger (5) are connected by first piping (21) though which a refrigerant flows, the refrigerant circuit (100) being configured so as to be capable of performing a defrosting operation for introducing the refrigerant compressed by the compressor (1) into the outdoor heat exchanger (5); a heating medium circuit (200) in which a pump (12), the cascade heat exchanger (3), and an indoor heat exchanger (11) are connected by second piping (23) through which a heating medium flows; and a control device (31) configured so as to control the compressor (1) and the pump (12). The control device (31) is configured so that, when the amount of heat stored in the heating medium is less than a threshold value, the warming capacity of the indoor heat exchanger (11) is reduced when a transition is made from a warming operation to the defrosting operation.
(FR) La présente invention concerne un climatiseur (1000) comprenant : un circuit (100) de fluide frigorigène dans lequel un compresseur (1), une soupape de commutation (2), un échangeur de chaleur en cascade (3), un détendeur (4) et un échangeur de chaleur extérieur (5) sont reliés par une première tuyauterie (21) apte à être traversée par un fluide frigorigène, le circuit (100) de fluide frigorigène étant conçu pour pouvoir effectuer un fonctionnement de dégivrage permettant d'introduire le fluide frigorigène comprimé par le compresseur (1) dans l'échangeur de chaleur extérieur (5); un circuit (200) d'agent caloporteur dans lequel une pompe (12), l'échangeur de chaleur en cascade (3) et un échangeur de chaleur intérieur (11) sont reliés par une seconde tuyauterie (23) apte à être traversée par un agent caloporteur; et un dispositif de commande (31) conçu pour commander le compresseur (1) et la pompe (12). Le dispositif de commande (31) est conçu pour que, lorsque la quantité de chaleur stockée dans l'agent caloporteur est inférieure à une valeur seuil, la capacité de chauffage de l'échangeur de chaleur intérieur (11) soit réduite lors d'une transition d'un fonctionnement de chauffage au fonctionnement de dégivrage.
(JA) 空気調和装置(1000)は、冷媒が流れる第1の配管(21)で、圧縮機(1)、切替弁(2)、カスケード熱交換器(3)、膨張弁(4)、室外熱交換器(5)が接続され、圧縮機(1)から吐出された冷媒を室外熱交換器(5)に導入する除霜運転を行なうことが可能に構成された冷媒回路(100)と、熱媒体が流れる第2の配管(23)で、ポンプ(12)、カスケード熱交換器(3)、室内熱交換器(11)が接続された熱媒体回路(200)と、圧縮機(1)およびポンプ(12)を制御するように構成される制御装置(31)とを備える。熱媒体の蓄熱量がしきい値よりも少ない場合には、制御装置(31)は、暖房運転から除霜運転に移行するときに、室内熱交換器(11)の暖房能力を低下させるように構成される。
