Abstract
(EN)
In order to suppress excessive pressure rise during high-temperature hot-water supply of a refrigeration cycle device capable of performing an air-conditioning hot-water supply complex system hot-water supply operation, and ensure a predetermined hot-water supply capacity within the use range of a compressor, an air-conditioning hot-water supply complex system (100) is provided with a compressor (1), a plate water heat exchanger (16), a hot-water supply pressure reduction mechanism (19), and an outdoor heat exchanger (3). The air-conditioning hot-water supply complex system (100) is further provided with a high pressure sensor (201) which detects the high pressure of the compressor (1), and a control device (110) which calculates the condensation temperature of the plate water heat exchanger (16) on the basis of the high pressure detected by the high pressure sensor (201), and when the calculated condensation temperature is higher than or equal to a preset condensation temperature target value, performs condensation temperature control for controlling the operating frequency of the compressor (1) on the basis of the difference between the calculated condensation temperature and the condensation temperature target value, and in parallel with the condensation temperature control, performs opening control for controlling the opening of the hot-water supply pressure reduction mechanism (19) on the basis of the difference between a present opening and a preset opening target value of the hot-water supply pressure reduction mechanism (19).

L'invention porte sur la réfrigération. Pour supprimer l'élévation excessive de la pression pendant la distribution d'eau chaude à haute température d'un dispositif à cycle de réfrigération capable d'effectuer une opération de distribution d'eau chaude de climatisation d'un système complexe de distribution d'eau chaude, et d'assurer une capacité de distribution d'eau chaude prédéterminée dans la plage d'utilisation d'un compresseur, un système complexe de distribution d'eau chaude de climatisation (100) est équipé d'un compresseur (1), d'un échangeur de chaleur à eau à plaques (16), d'un mécanisme de réduction de pression de distribution d'eau chaude (19) et d'un échangeur de chaleur extérieur (3). Le système complexe de distribution d'eau chaude de climatisation (100) est en outre équipé d'un capteur de haute pression (201) qui détecte la haute pression du compresseur (1) et d'un dispositif de commande (110) qui calcule la température de condensation de l'échangeur de chaleur à eau à plaque (16) sur la base de la haute pression détectée par le capteur de haute pression (201) et qui, lorsque la température de condensation calculée est supérieure ou égale à une valeur cible de température de condensation prédéterminée, exécute une commande de température de condensation pour commander la fréquence de fonctionnement du compresseur (1) sur la base de la différence entre la température de condensation calculée et la valeur cible de la température de condensation, et en parallèle avec la commande de la température de condensation, exécute une commande d'ouverture pour commander l'ouverture du mécanisme de réduction de pression de distribution d'eau chaude (19) sur la base de la différence entre l'ouverture présente et une valeur cible d'ouverture prédéterminée du mécanisme de réduction de pression de distribution d'eau chaude (19).
