摘要： In a hot-water supply system with a heat pump cycle (H), a control unit (100) controls operation of an expansion valve (3) based on a temperature difference ( DELTA T) between a refrigerant temperature (Tr) at an outlet side of a refrigerant passage (21) in a water heat exchanger (2) and a water temperature (Tw) at an inlet side of a water passage (22) in the water heat exchanger. When the expansion valve is controlled in a direction increasing a valve opening degree, the control unit sets an upper limit opening degree of the expansion valve, for obtaining a refrigerant pressure corresponding to a target hot-water temperature, and controls the expansion valve in an opening degree range smaller than the upper limit opening degree.

摘要： In a control unit of a hot-water supply system, a boiling time period is estimated based on a hot-water amount stored in a tank at a time of 23:00, a boiling start time is adjusted so that boiling operation is finished at a time immediately before 7:00. For example, when the hot water amount stored in the tank is smaller at the time of 23:00, the boiling time period is made longer and the boiling start time is made earlier. On the other hand, when the hot water amount stored in the tank is larger at the time of 23:00, the boiling time period is made shorter and the boiling start time is made later.

摘要： PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply apparatus A which is prevented from causing a decline in hot water supply capacity due to a decline in refrigerant pressure in a heat pump cycle H. SOLUTION: This hot water supply apparatus A is provided with the heat pump cycle H which is constituted by annularly connecting a compressor 1, the refrigerant flow passage 21 of a water heat exchanger 2, an expansion valve 3, and an air heat exchanger 4 to which an outdoor fan 41 is attached to each other; a hot water circuit W which is constituted by connecting a hot water tank 5 to the hot water flow passage 22 of the water heat exchanger 2 through a hot water pipeline 51 and also connecting a pump 6 to the midcourse of the pipeline 51; and a controller which controls the valve travel of the expansion valve 3 based on the difference between the reminder obtained when the temperature of hot water on the inlet side of the hot water flow passage 22 is subtracted from the temperature of a refrigerant on the outlet side of the refrigerant flow passage 21 and a target temperature difference. When the controller controls the valve 3 in the opening direction of the valve 3, the controller sets the valve travel of the valve 3 for obtaining the refrigerant pressure corresponding to a target hot water supply temperature as the upper-limit valve travel of the valve 3 and maintains the high-pressure side refrigerant pressure in the heat pump cycle H at or higher than a prescribed refrigerant pressure by controlling the valve 3 in the opening direction within a valve travel range lower than the upper-limit valve travel.

摘要： PROBLEM TO BE SOLVED: To provide a hot water supply device in which the wasteful heat radiation of stored hot water is prevented without cutting off the hot water. SOLUTION: The flow rate of water upon boiling up is obtained from any of desired temperature, reference water temperature and reference heating capacity or the combination thereof on the basis of the amount of stored hot water Lt at 23:00 to estimate boiling up time and adjust boiling up start time t-start. For instance, (a) when the amount of stored hot water Lt at 23:00 is small, much boiling up time tw is taken, so that the boiling up start time t-start is advanced. (b) When the amount of stored hot water is large, the boiling up time tw may be less taken, so that the boiling up start time t-start is delayed.

摘要： PROBLEM TO BE SOLVED: To reduce the number of output wiring being extended from each load-detecting element. SOLUTION: Electrical wiring 5 for connecting each of a number of load- detecting elements 31 to a signal-processing part 32 is bundled, and at the same time an analog switch 3211 is provided between each of the load-detecting elements 31 and the signal-processing part 32. Also, a load resistor 3212 is connected to each of the load-detecting elements 31, and the potential of the connection point is outputted to the signal-processing part 32 as an output signal. Then, by successively turning on and off the analog switch 3211, the load-detecting elements 31 are connected to the signal-processing part 32 one by one. As a result, an output signal according to a load being applied to each of the load-detecting elements 31 is changed into serial form and is outputted to the signal-processing part 32, thus eliminating the number of electrical wiring being extended from each of the load-detecting elements 31.
