[0012] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 As shown, a heating system for heating residential buildings includes an electric boiler 1, a heat storage tank 2, a radiator 3, a return pipe 4, a circulation pump 5 and a control system 6, wherein the electric boiler 1, the heat storage tank 2, the radiator 3, the return pipe 4 and the circulation pump 5 are connected in sequence and arranged in a closed loop.
[0014] like Figure 1 As shown, a first solenoid valve 7 and a second solenoid valve 8 are respectively provided in front and rear of the heat storage tank 2, and a control system 6 is used to control the first solenoid valve 7 and the second solenoid valve 8 to switch.
[0015] like Figure 1 As shown, the first interface of the first solenoid valve 7 is connected to the electric boiler 1 , the second interface is connected to the outlet end of the heat storage tank 2 , and the third interface is connected to the inlet end of the heat storage tank 2 .
[0016] like Figure 1 As shown, the first interface of the second solenoid valve 8 is connected to the outlet end of the heat storage tank 2 , the second interface is connected to the radiator 3 , and the third interface is connected to the return pipe 4 .
[0017] like Figure 1 , Figure 2 As shown, the control system 6 includes a system power supply circuit breaker 61, a water pump power supply circuit breaker 62, an electric energy meter 63, a 24V DC power supply 64, a core controller 65, an HMI touch screen 66, a heat meter 67 and a solenoid valve control switch 68. The core controller 65 is a YZ168 embedded controller with an NTC temperature measurement unit.
[0018] like Figure 1 As shown, a first temperature sensor 91 is provided at the position of the return pipe 4, a second temperature sensor 92 is provided in the heat storage tank 2, a third temperature sensor 93 is provided at the inlet end of the heat storage tank 2, and a fourth temperature sensor 94 is provided at the outlet end of the heat storage tank 2.
[0019] like Figure 1 As shown, the first temperature sensor 91 , the second temperature sensor 92 , the third temperature sensor 93 and the fourth temperature sensor 94 are all connected to the NTC temperature measurement unit in the core controller 65 .
[0020] When the energy meter 63 is measuring off-peak electricity:
[0021] When the temperature of the heated room is lower than the set value, that is, the temperature value fed back by the first temperature sensor 91 is lower than the set value, the control system 6 switches the first solenoid valve 7 to conduct the first interface and the second interface, and switches the second solenoid valve 8 to conduct the first interface and the second interface. The control system 6 first heats the room at maximum power to achieve electric assisted heating.
[0022] When the temperature of the heated room reaches the set value, that is, the temperature value fed back by the first temperature sensor 91 reaches the set value, the control system 6 switches the first solenoid valve 7 to the first interface and the third interface to be conductive, and the second solenoid valve 8 keeps the first interface and the second interface conductive. At this time, on the one hand, the temperature of the heated room is heated to the set value, and at the same time, the excess heat is stored in the heat storage tank 2 to achieve heat storage heating.
[0023] When the temperature of the heated room is higher than the set value, that is, the temperature value fed back by the first temperature sensor 91 is higher than the set value, the first solenoid valve 7 remains unchanged, that is, the first interface and the third interface are connected, the second solenoid valve 8 switches to the first interface and the third interface being connected, and the electric boiler 1 performs the heat storage mode at full power during valley power. The design of the electric boiler 1 and the heat storage tank 2 ensures that the total amount of heat stored during valley power periods meets the heating demand in other periods.
[0024] When the energy meter 63 is not measuring off-peak electricity:
[0025] The electric boiler 1 stops working, the first solenoid valve 7 switches to a state where the first interface and the third interface are connected, the second solenoid valve 8 switches to a state where the first interface and the second interface are connected, and the room heating uses the heat energy stored in the heat storage tank 2 to provide hot water for heating the room, thereby achieving heat release heating.
[0026] Therefore, by using an electric boiler 1 for heating and configuring a high-efficiency heat storage tank 2, the electric energy can be efficiently converted into heat energy and stored in the heat storage tank 2 when the off-peak electricity cost is low. The electric boiler 1 is turned off during peak and off-peak periods, and the heat energy in the heat storage tank 2 is used to provide hot water to the indoor radiator 3 to ensure a constant indoor temperature. The user can reduce the electricity cost of the heating equipment to the lowest value and maximize the energy-saving state of the equipment.
[0027] During the actual application of the control system 6, technical means of automatic networking can be added to save real-time data on the cloud platform. The working mode of the control system 6 can be configured or the heating temperature can be set through the cloud platform. It can be operated in time-sharing, by appointment, and in low-temperature antifreeze mode.
[0028] During use, the electricity usage can be automatically monitored based on the multi-rate electricity meter. Through the cloud platform, users can automatically adjust the operating status of the heating equipment anytime and anywhere. Users can reduce the electricity cost of the heating equipment to the lowest value and maximize the energy-saving status of the equipment.
[0029] The control system 6 uses an embedded controller to implement all control logics, so in actual use, it can also be set up so that all control logics can be set on the cloud platform or locally on the device.
[0030] During the transformation or upgrading of old equipment, a heat storage tank 2 can be installed in the heating pipeline of an ordinary electric boiler 1. At the same time, a cloud platform controller can be used for multi-mode time-sharing operation. Energy storage is completed during off-peak hours, and the electric boiler 1 is shut down during non-off-peak hours. The heat storage tank 2 is used to release heat for heating. By reasonably configuring the system's working mode, all the heat energy required for room heating can be obtained during the off-peak electricity price period, solving the problem of excessively high electricity charges for heating with electric boilers 1 in residential buildings.
[0031] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
