Title (EN) AIR CONDITIONING DEVICE
(FR) DISPOSITIF DE CLIMATISATION
(JA) 空気調和装置
Abstract:
(EN) This air conditioning device is configured so that during an operation in which some of a plurality of use-side heat exchangers serve as a condenser and the others serve as an evaporator, when, from between use-side heat exchangers (31a, 31b) that are operating in the same operation mode as a heat source-side heat exchanger, there is a request from the first use-side heat exchanger (31b) to increase heat-exchange capability, the heat exchange capacity of a heat source-side heat exchanger (13) is made small, the opening degree of an expansion valve (32a) corresponding to the second use-side heat exchanger (31a) that did not make a heat-exchange capability increase request is controlled, and the flow rate of a refrigerant flowing to the second use-side heat exchanger (31a) is reduced. This configuration enables the capability of the first use-side heat exchanger to be made greater than the design capacity, and prevents the capability of the second use-side heat exchanger from becoming excessive.
(FR) L'invention porte sur un dispositif de climatisation, lequel dispositif est configuré de telle sorte que, pendant un fonctionnement dans lequel certains d'une pluralité d'échangeurs de chaleur côté utilisation jouent le rôle de condenseur et les autres jouent le rôle d'évaporateur, quand, à partir d'entre les échangeurs de chaleur côté utilisation (31a, 31b) qui fonctionnent dans le même mode de fonctionnement qu'un échangeur de chaleur côté source de chaleur, il y a une demande à partir du premier échangeur de chaleur côté utilisation (31b) pour augmenter la capacité d'échange de chaleur, la capacité d'échange de chaleur d'un échangeur de chaleur côté source de chaleur (13) est rendue petite, le degré d'ouverture d'une soupape de détente (32a) correspondant au second échangeur de chaleur côté utilisation (31a) qui n'a pas effectué une demande d'augmentation de capacité d'échange de chaleur est commandé, et le débit d'écoulement d'un réfrigérant s'écoulant vers le second échangeur de chaleur côté utilisation (31a) est réduit. Cette configuration permet à la capacité du premier échangeur de chaleur côté utilisation d'être rendue supérieure à la capacité nominale, et empêche la capacité du second échangeur de chaleur côté utilisation de devenir excessive.
(JA)  本発明に係る空気調和装置は、複数の利用側熱交換器のうちの一部が凝縮器、その他が蒸発器となる運転中、熱源側熱交換器と同じ運転モードで運転している利用側熱交換器(31a,31b)のうち、第1の利用側熱交換器(31b)から熱交換能力を増大させる要求があると、熱源側熱交換器(13)の熱交換容量を小さくし、熱交換能力増大要求の無い第2の利用側熱交換器(31a)に対応する膨張弁(32a)の開度を制御して、第2の利用側熱交換器(31a)に流れる冷媒の流量を減少させる。 これにより、第1の利用側熱交換器の能力を設計容量よりも大きくするとともに、第2の利用側熱交換器の能力が過大となるのを抑制することができる。
