Title (EN) HEAT SOURCE SYSTEM
(FR) SYSTÈME DE SOURCE DE CHALEUR
(JA) 熱源システム
Abstract:
(EN) A heat source system provided with: a coolant circuit obtained by connecting a compressor, a heat-source-side heat exchanger, an expansion valve, and a load-side heat exchanger; a heating medium circuit having a flow amount adjustment pump for pumping a heating medium to the load-side heat exchanger, the heating medium circuit circulating the heating medium to a load device provided on the downstream side of the load-side heat exchanger; and a control device for controlling the frequency of the flow amount adjustment pump. The control device increases the frequency of the flow amount adjustment pump when the evaporation temperature of the load-side heat exchanger is reduced to a flow amount threshold.
(FR) L'invention concerne un système de source de chaleur comprenant : un circuit d'agent de refroidissement obtenu par raccordement d'un compresseur, un échangeur de chaleur côté source de chaleur, une vanne de détente et un échangeur de chaleur côté charge ; un circuit d'agent chauffant comportant une pompe de réglage de quantité d'écoulement destinée à pomper un agent chauffant vers l'échangeur de chaleur côté charge, le circuit d'agent chauffant faisant circuler l'agent chauffant vers un dispositif de charge disposé sur le côté aval de l'échangeur de chaleur côté charge ; et un dispositif de commande destiné à commander la fréquence de la pompe de réglage de quantité d'écoulement. Le dispositif de commande augmente la fréquence de la pompe de réglage de quantité d'écoulement lorsque la température d'évaporation de l'échangeur de chaleur côté charge diminue jusqu'à un seuil de quantité d'écoulement.
(JA) 圧縮機、熱源側熱交換器、膨張弁、及び負荷側熱交換器が接続されてなる冷媒回路と、熱媒体を負荷側熱交換器に圧送する流量調整ポンプを有し、負荷側熱交換器の下流側に設けられた負荷装置に熱媒体を循環させる熱媒体回路と、流量調整ポンプの周波数を制御する制御装置と、を備えた熱源システム。制御装置は、負荷側熱交換器の蒸発温度が流量閾値まで低下したときに、流量調整ポンプの周波数を増加させるものである。
