Embodiment approach 1

[0084] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the embodiment described below is all for showing a specific example of this invention. Numerical values, shapes, materials, constituent elements, arrangement positions and connection forms of constituent elements, steps, order of steps, etc. shown in the following embodiments are merely examples, and are not intended to limit the present invention. In addition, among the constituent elements of the following embodiments, constituent elements not described in the independent claims showing the highest concept are described as arbitrary constituent elements.

[0085] first, figure 1 It is a flowchart showing the outline of processing in the heat pump hot water supply system according to Embodiment 1 of the present invention.

[0086] Such as figure 1 As shown, the heat pump hot water supply system according to Embodiment 1 of the present invention first obt...

Embodiment approach 2

[0202] Next, heat pump hot water supply system 3000 according to Embodiment 2 of the present invention will be described. In Embodiment 1 described above, the HP control device 209 acquires the state of the local system from the server 208, and selects an operation method corresponding to the state of the system. However, such control cannot be performed in areas where the energy supplier 207 does not transmit information to the server 208 . In this case, in the present embodiment, it is possible to effectively reduce the amount of power flowing backward to the system and to suppress electricity charges.

[0203] Figure 21 It is a structural diagram explaining the heat pump type hot water supply system 3000 provided with the power generation device of this embodiment. Figure 21 and figure 2 The difference is that the HP control device 309 is not connected to the server 208 . Therefore, for figure 2 The same constituent elements are denoted by the same reference numera...

Abstract

An operating method for a heat pump including an information acquisition step for acquiring, per unit of time, the generated power, load power, surplus power, and size of impact, and an operation control step for controlling the operation of the heat pump in a manner such that the power consumed for heat-generating by the heat pump conforms to the surplus power per unit of time, wherein the operation control step involves: permitting consumption of power supplied from an energy provider, and controlling the operation of the heat pump in a manner such that the reverse flow of the surplus power is close to zero, when the size of the impact exceeds a first pre-set threshold; and permitting the reverse flow of the surplus power, and controlling the operation of the heat pump in a manner such that the amount of consumption of the power supplied from the energy provider is close to zero, when the size of the impact is equal to or less than a second pre-set threshold.

Description

technical field [0001] The present invention relates to a heat pump system including a power generating device such as a solar power generating device and power consuming equipment such as a heat pump. Background technique [0002] Power generation devices such as solar power generation and wind power generation are devices for the purpose of generating energy. For example, solar power generation is a natural energy power generation device that converts the energy of sunlight into electricity and supplies it to households, and the power generated always fluctuates according to changes in weather or meteorological conditions. [0003] The heat pump hot water supply device is a device that absorbs heat from the atmosphere, compresses and heats the refrigerant using electricity, and forms hot water from water through a heat exchanger. Compared with conventional heater-type electric water heaters, it is an energy-saving hot water supply. device. [0004] A heat pump hot water ...
