摘要： A storage type hot water supplying system 1 includes: a heat exchanger 38 configured to exchange heat between a heating medium and water; a storage hot water tank 8; a first pump 11 configured to circulate the heating medium in a first circuit connecting the heat exchanger 38 and a heat pump device 3 to each other; a second pump 12 configured to circulate the water in a second circuit connecting the heat exchanger 38 and the hot water storage tank 8 to each other; and a control device 50 configured to control the first pump and the second pump. In a heat accumulating operation in which the hot water is accumulated in the hot water storage tank 8, the first pump 11 is controlled so that the temperature of the heating medium heated by the heat pump device 3 becomes equal to a target temperature, and the second pump 12 is controlled so that a water temperature difference that is the difference between the temperature of the hot water heated in the heat exchanger 38 and the temperature of the water before being heated in the heat exchanger 38 becomes equal to a heating medium temperature difference that is the difference between the temperature of the heating medium heated by the heat pump device 3 and the temperature of the heating medium before being heated by the heat pump device 3.

摘要： A storage water heater capable of ensuring hot water supply temperature stability even if there is fluctuation in hot water supply-side flow rate is provided. The storage water heater includes: a hot water supply heat exchanger 52 for performing heat exchange between hot water in the hot water storage tank 8 and supply water; a hot water supply heat source conduit 46 that guides water from an upper portion of the hot water storage tank 8 to a lower portion of the hot water storage tank 8 via the hot water supply heat exchanger 52; a hot water supply heat source pump 48 that circulates water in the hot water supply heat source conduit 46, and a control section 36. In a hot water supply operation of heating supply water using a heat source that is the hot water in the hot water storage tank 8, the control section 36 performs PID control to calculate an output of a hot water supply heat source pump 48, the output bringing a heat source-side flow rate Fl, which is a flow rate of hot water flowing in the hot water supply heat source conduit 46, to a target flow rate Ftgt, for each control interval ΔTc. Here, the control section 36 sets the control interval ΔTc to be equal to the monitoring interval ΔTf when a hot water supply-side flow rate Fk is stable, and sets the control interval ΔTc to a control interval ΔTcmin, which is shorter than the monitoring interval ΔTf, when the hot water supply-side flow rate Fk rapidly fluctuates.

摘要： A heat medium circulation system (1) includes a heat pump device (11) that heats a heat medium, a pump (2) that circulates the heat medium in a circulation circuit passing through an indoor-heating terminal (20) and the heat pump device (11), load detection means that detects an indoor-heating load during an indoor-heating operation in which the heat medium heated by the heat pump device (11) is supplied to the indoor-heating terminal (20), and a controller (6) that adjusts a heating power of the heat pump device (11) and a circulation flow rate that is a flow rate of the heat medium passing through the heat pump device (11). In the case where the indoor-heating load detected when the circulation flow rate is equal to a first flow rate is lower than a minimum load that is a load balanced with a minimum heating power of the heat pump device (11), the controller (6) adjusts the circulation flow rate such that the circulation flow rate is higher than the first flow rate.
