Problems solved by technology

[0009] However, in the above control method, if a shutdown signal from the energy supplier is received, the heat pump warm water heating system will stop running immediately
As a result, the room temperature decreases over time, affecting user comfort
In particular, if the power is turned off when the heat storage tank and the house do not have sufficient heat storage, the room temperature will drop significantly and the user's comfort will be affected.

Embodiment approach 1

[0057] figure 1 It is a figure which shows the heat pump heating system concerning Embodiment 1 of this invention. exist figure 1 In this case, the house is supplied with power from an energy supplier (power supply source) 4 through the first and second power systems. The first power system is a power system that supplies electric power stably. In addition, the first electric power system is a relatively high electric power system, and the electric power consumption is measured by the first electric meter 6 . On the other hand, the second power system is a power system capable of stopping power supply by an energy supplier for an arbitrary period of time. In addition, the second electric power system is an electric power system having a lower electric cost than the first electric power system, and the electric power consumption is measured by the second electric meter 7 .

[0058] In addition, in figure 1 In the house shown, an electric load 5 , a heating system control u...

Embodiment approach 2

[0108] (Embodiment 2: HP cascade type)

[0109] In the second embodiment, the differences from the first embodiment will be mainly described.

[0110] Figure 7 It is a figure which shows the heat pump heating system 200 which concerns on Embodiment 2 of this invention. Figure 7 Shown heat pump heating system 200 with figure 1 The difference is that the heating system control unit 40, the heat pump 30, the tank 2 and the radiator 3 are integrally formed.

[0111] The heat pump 30 is a heat pump of an air heat source, and a refrigerant (for example, R410A) and water exchange heat through a condenser (not shown) to generate high-temperature warm water. The tank 2 stores warm water generated by the heat pump 30 and is used as a buffer to supply necessary heat to keep the room temperature constant when the outside air temperature drops sharply. The radiator 3 is a device that raises the temperature of the room with warm water supplied from the tank 2 . The heating system con...

Abstract

A heating system includes: a heat generation unit (1) which generates heat using electricity supplied through a second power system of a lower electricity rate; a heat storage unit (2) which stores the heat generated by the heat generation unit; a heat radiation unit (3) which radiates the heat stored in the heat storage unit; and a control unit (8) which causes, when receiving, from a power supplier (4), a signal indicating that a supply of electricity through the second power system is to be stopped after an elapse of a predetermined period of time, the heat generation unit (1) to generate additional heat that is required while the supply of electricity through the second power system being suspended, during a period of time from when the signal is received to when the supply of electricity through the second power system is stopped.

Description

technical field [0001] The invention relates to a heating system, in particular to a heat pump warm water heating system. Background technique [0002] Energy suppliers in some European countries (Germany, etc.) allow power load balancing from the outside for a specified period (hereinafter referred to as "off time period") and a specified number of times in a day in the contract with the customer. The power supply to the heat pump heater can be cut off (hereinafter referred to as "turning off") freely, and as compensation, cheap electricity costs can be provided. [0003] Therefore, in response to the above-mentioned control from the outside, the heat pump warm water heater has a relay switch that turns the power on or off when receiving a ripple signal from an energy supplier.
