Document Type and Number:
Japanese Patent JP6899682
Kind Code:
B2
Abstract:
To provide a hot water supply system capable of reducing deviation of power purchase amounts from a commercial power source by time zones.SOLUTION: A hot water supply system includes a hot water storage tank 20 for storing hot water inside, a heat pump unit 30 for heating the hot water stored in the hot water storage tank 20 to a set temperature by using generated heat, and a control device 50 for controlling an operation of the heat pump unit 30. The control device 50 divides a prescribed period into a plurality of time zones, acquires a heat pump estimation power consumption indicating an estimation power consumption by each time zone of the heat pump unit 30, acquires a load estimation power consumption indicating estimation power consumption by each time zone of domestic load 140, and operates the heat pump unit 30 in the time zone overlapped to the time zone in which electric power of a solar power generating portion 110 can be obtained, in the zone time in which an estimation total value indicating the total value of the heat pump estimation power consumption amount and the load estimation power consumption is over a prescribed threshold value.SELECTED DRAWING: Figure 1
