[0028] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

[0029] It should be understood that the various steps described in the method implementation of the present application can be performed in different orders and / or performed in parallel. In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present application is not limited in this respect.

[0030] As described in the background technology section, reference Figure 1 , is a schematic diagram of the daily heat storage capacity of the centralized heating system, where the sinusoidal lines (dark lines) represent the daily outdoor temperature fluctuations, and the cosine lines (light lines) represent the daily heat load demand. The two fluctuate in opposite directions. For example, when the temperature is low in the early morning or at night (dark line valley), the heat load demand reaches a peak (light line peak), indicating that more heating is needed at this time; conversely, when the temperature rises at noon (dark line peak), the heat load demand decreases (light line valley).

[0031] refer to Figure 2, which is a schematic diagram of the heat storage of the centralized heating system for multiple days during the extreme cold period. The cosine-fluctuating line (dark line) represents the annual average fluctuation of the outdoor temperature, and the sine-fluctuating line represents the annual heat load demand. It can be seen that the outdoor temperature and the heat load demand show significant seasonal inverse fluctuations. In winter (December-February), the outdoor temperature is low and the heat load demand reaches the peak period of the year, that is, a large amount of heating is required during the extreme cold period; in summer (June-August), the outdoor temperature is high and the heat load demand is close to the valley period of the year, at this time, excess heat storage can be carried out.

[0032] refer to Figure 3 , which is the working schematic diagram of the heat storage system.

[0033] Among them, the heat source is the core and equipment for generating heat in the centralized heating system, which can be a boiler, heat pump, solar collector or industrial waste heat, etc.; the heat exchanger is the room that transfers heat between the heat source and the heat user and energy storage equipment to adjust the temperature or improve energy efficiency; the energy storage equipment is used to store excess heat and can be released when there is an imbalance between supply and demand; the heat user is the heat consumption terminal, which can be urban residential users, building heating, industrial processes, domestic hot water, etc.

[0034] After the heat source generates heat, the high-temperature medium (such as water, steam or heat transfer oil) is transferred to the downstream through the heat exchanger; when the heat user demand is high, the heat exchanger will directly transport the heat to the heat user. When the heat supply of the heat source exceeds the user demand, the excess heat is stored in the energy storage device through the heat exchanger; when the heat user demand exceeds the real-time energy supply capacity of the heat source, the energy storage device releases the stored heat through the heat exchanger to supplement the energy supply gap.

[0035] In order to allocate the energy of the energy storage device to heat users more flexibly, the size of the energy storage device can be designed according to the target area and the usage habits of the target area. To this end, the present application proposes a size parameter design method for the energy storage device.

In an embodiment of the present application, the energy storage device may include a small energy storage device and a large energy storage device. The small energy storage device and the large energy storage device may be a water heat storage tank or a phase change PCM (phase change material) heat storage tank. Among them, the large energy storage device can be used to store a large amount of heat energy to cope with the extreme cold period, and at the same time can ensure that sufficient heat energy is accumulated during low demand periods, and can release a large amount of stored heat energy during peak heat load periods or extreme cold periods, alleviate real-time energy supply pressure, and improve the stability of the centralized heating system. This scaled method of storing heat energy can also reduce the storage cost of unit heat energy, reduce the energy consumption of frequent starting and stopping of heat sources, and extend the life of the energy storage device; the small energy storage device can be used for short-term (such as daily) or instantaneous heat load fluctuations, can quickly release a small amount of heat energy, avoid system overload or response delay, and can also act as a buffer device between the heat source and the user, stabilize the pipeline pressure and flow, and prevent damage to the heating equipment due to thermal shock or sudden pressure changes. In addition, during the startup phase of the heat storage system, the heat in the small energy storage device can be used to quickly preheat the pipeline or equipment, shortening the time it takes for the heat storage system to reach stable operation.
