The heat storage device is provided with two ports which are respectively connected with external equipment, namely a heat energy input end 8 and a heat energy output end 9, and the heat energy input end 8 is connected with external heat supply equipment to supply heat to the heat storage device. The heat energy output end 9 is connected with external equipment needing heat, the heat of the heat storage device is output, and heat is supplied to other equipment.
The cold storage device is similar to the heat storage device in structure and adopts a material for storing cold. Chemical storage, such as converting a liquid substance to a solid state, may also be used. A material is used to store the cold. The heat insulation material is arranged outside the storage material, so that heat can be effectively prevented from diffusing, and heat (cold) can be effectively kept.
The connection mode of the equipment and the heat or cold storage device is respectively connected through two pipelines, namely an input pipeline and an output pipeline, and the connection ports of the input pipeline and the output pipeline are provided with switch valves to be controlled to be switched on and off according to working requirements.
For example, in the heat storage device, the input pipeline inputs the high-temperature medium, the heat exchange is carried out through the heat energy input end of the heat storage device, the heat is led into the heat storage device, and then the cooled medium flows back to the equipment through the output pipeline.
In the scheme, the transfer heat exchanger 2 transmits heat through a medium in the transfer heat exchanger 2, the transfer heat exchanger 2 is provided with two ends, namely two loops which are not coupled and connected, the medium in an input loop collects heat at a heat-radiating shell of the heat-releasing device 1 such as a refrigerator, absorbs the heat of the medium in the input loop when passing through a heat-absorbing material in the transfer heat exchanger, and is coupled with the other loop, namely an output loop, the medium in the output loop absorbs the heat in the heat-absorbing material, the heat is carried to and conducted to the heat storage device 3 along with the flowing of the medium, the heat storage device 3 is provided with a heat storage module 11 formed by the heat-absorbing material, the heat is stored, and then the heat is conducted from the heat storage device 3 to heating equipment 6 needing heat absorption, such as a water heater, a heating device, a heat-preserving cooking appliance and the like, through the terminal heat exchanger 4; the input loop and the output loop are coupled through the heat absorbing material of the intermediate heat exchanger 2, so that heat can be stored in the heat storage device 3 from the heat releasing equipment 1 with different temperatures, and the condition that when the temperature of the heat releasing equipment 1 is lower than that of the heat storage device 3, the heat reversely flows can not occur; the terminal heat exchanger 4 and the relay heat exchanger 2 have the same structure, are arranged at a heat energy output end 9 of the heat storage device 3 and are connected with two or more heating devices 6 or refrigerating devices 14 through the medium distribution mixing device 5, the input end of each medium distribution mixing device 5 is connected with two or more terminal heat exchangers 4, the temperature of the output end of each terminal heat exchanger 4 is different, and the temperature of the medium distribution mixing device 5 can be adjusted by controlling the proportion of the media of the terminal heat exchangers 4 with different temperatures, so that the temperature of the medium distribution mixing device 5 is adjusted, and the temperature of the heating devices 6 or refrigerating devices 14 is adjusted.
Different devices such as air conditioners, refrigerators and the like have different heat exchange amounts due to different devices, and the medium temperature output from the devices is also different. Meanwhile, when heat is generally transferred, the heat can only be transferred from the high temperature end to the low temperature end, if the temperature in the heat storage device 3 is higher than the medium temperature output by the equipment, and at this time, the heat storage device 3 still has a large amount of capacity for heat supply storage, the temperature of the heat storage device 3 cannot be stored at this time, but the heat of the heat storage device 3 is lost, so that the opposite effect is achieved. The same problem is encountered when the heat storage device 3 performs heat release. Therefore, there is a need for a relay heat exchanger 2 that regulates the temperature of the medium led from the equipment to the heat storage means 3/the cold storage means 13 and the temperature of the medium led from the heat/cold storage means 13 to the equipment so that heat transfer can be performed normally.

The port connected with each pipeline is provided with a switch valve 10, the opening and the closing of the switch valve can be controlled, and the opening degree can be controlled, so that the flow rate can be controlled. When heat exchange is needed, the switch valve 10 of the corresponding pipeline is opened, so that the heat exchange work can be carried out. When the operation is not required, the switching valve 10 is closed to stop the heat transfer.
When the heat storage operation of the equipment to the heat storage device 3 is performed, the medium at the heat absorption end in the intermediate heat exchanger 2 is changed from a liquid state to a gas state, the heat of the heat input pipeline is absorbed, and the medium temperature of the output pipeline connected with the equipment is reduced. After the medium in the transfer heat exchanger 2 reaches the heat release end, the medium becomes liquid by the gaseous state, the release heat, heat storage device 3 reaches the medium of the input pipeline of transfer heat exchanger 2 and heats, after the temperature rises, the backward flow is to heat storage device 3, the output pipeline of transfer heat exchanger 2 this moment is also exactly the input pipeline of heat storage device 3, after reaching heat storage device 3, release the heat in heat storage device 3, the medium after the reduction temperature then continues to flow to transfer heat exchanger 2 through its output pipeline. Therefore, through the transfer heat exchanger 2, heat absorption from the equipment end pipeline is continuously realized, heat release and heating are performed on the pipeline medium of the heat storage end, and heat transfer is realized. Even if the temperature released by the heat-releasing device is lower than the temperature in the heat storage device 3, the heat transfer can be performed.
The operation of the transit heat exchanger 2 is also suitable for the operation that the heat storage device 3 heats the equipment, or the cold storage device 13 absorbs cold and releases the cold, namely the operation is used as the terminal heat exchanger 4.

The working mode 2: when the thermoelectric generation device 16 directly supplies power to the electric equipment, if the generated energy is larger than the power consumption, the electric quantity of the power generation device is divided into two paths, one path directly supplies power to the equipment, and the other path charges and stores the power storage station 17.
Working mode 3: when the generated energy is less than the power consumption, the working mode 1 can be adopted, the power storage station 17 is directly used for supplying power, and the temperature difference power generation device 16 simultaneously charges the power storage station 17. The thermoelectric power generation device 16 and the power storage station 17 may supply power to the electric equipment at the same time, and the power amounts of the two may be integrated and supplied to the electric equipment.
The energy storage station of the exemplary embodiment of the present invention further includes an electric power generating system, the electric power generating system is connected to a household appliance having a kinetic energy output, such as a treadmill, the electric power generating system includes an electric motor, the electric motor is coupled to a mechanical movement shaft of a sports apparatus, such as a treadmill, a bicycle, a dumbbell, etc., the treadmill drives a generator to operate, and the mechanical energy is converted into electric energy to be stored in the power storage station 17.
