Description

Technical Field

[0001] This utility model relates to the field of heating technology, specifically to a modular water storage multi-source coupled heating system. Background Technology

[0002] In my country, urban heating using low-temperature waste heat recovery for clean energy has moved from pilot projects to large-scale applications. The emission reduction and economic viability of urban heating projects have been verified. However, widespread adoption is still constrained by low-grade heat source utilization technologies, resource misallocation, mismatch between end-user heating methods, and high investment costs. Currently, urban buildings rely on coal-fired boilers and a small number of decentralized waste heat recovery and electric heating devices to meet urban heating needs.

[0003] Traditional coal-fired boilers generally suffer from low thermal efficiency (typically only 60%-70%), high pollution emissions, and rising operating costs. According to actual measurement data, a 50-ton coal-fired boiler emits approximately 30,000 tons of CO2 and 44.45 tons of SO2 annually, making it one of the main sources of pollution for urban heating.

[0004] In terms of energy costs, the economic viability of traditional energy supply models continues to deteriorate.

The system power supply 20 provides power to the multi-energy input module 1, the secondary heat supplement module 2, the smart heating platform 5, the intelligent regulating device for the building heating inlet 4, the heat source energy storage circulating water pump 6, and the heat energy release circulating pump 12. The hot water storage tank 3 is equipped with a temperature sensor 10 and a water level sensor 11; The intelligent heating platform 5 is connected to the heat source energy storage circulating water pump 6, the heat energy release circulating pump 12, the temperature sensor 10, the water level sensor 11, the secondary heat replenishment module 2, and the building heating inlet intelligent adjustment device 4. The intelligent regulating device 4 for building heating inlet has an indoor temperature sensor 15, which is installed in the building to be heated and is connected to the intelligent heating platform 5.

[0019] Preferably, the hot water storage tank 3 is equipped with an upper water distributor 8 and a lower water distributor 9. The heat storage tank 3 has its heat storage inlet and heat release outlet located in the upper water distributor 8; The heat storage outlet and heat release return outlet of the hot water storage tank 3 are located in the lower water distributor 9.

[0020] Preferably, a first electric switch valve 7 is installed on the pipeline between the outlet of the multi-energy input module 1 and the heat storage inlet of the hot water tank 3; The outlet of the secondary heat replenishment module 2 is equipped with a second electric switch valve 18; The first electric switch valve 7 and the second electric switch valve 18 are respectively connected to the intelligent heating platform 5 via signal.

[0021] Preferably, the secondary heat supplement module 2 is an electric boiler or a gas boiler.

[0022] It is understood that the system disclosed in this embodiment includes multiple energy input modules 1, a secondary heat supplement module 2, a hot water storage tank 3, a smart heating platform 5, and at least one building heating module. In this embodiment, the multiple energy input modules 1 constitute the main heat source of the system, the secondary heat supplement module 2 serves as an auxiliary or backup heat source, the hot water storage tank 3 is used for large-scale heat storage and buffering, the smart heating platform 5 serves as the control center of the entire system, and the building heating module constitutes the heating execution unit directly facing end users. In addition, the system is also equipped with a system power supply 20 to provide power to energy-consuming equipment. The system power supply 20 consists of a green electricity grid 17 and mains power 19, used to drive the heat source energy storage circulating water pump 6 and the heat energy release circulating pump 12 for water circulation. Green electricity such as solar and wind power is the primary power source; if there is no green electricity resource, mains power 19 can be used.

[0023] Specifically, the system consists of two relatively independent but coupled closed water circulation loops.

[0024] The first closed-loop circuit is a heat storage circuit, which converts external energy into heat energy and stores it in a hot water storage tank 3. This circuit consists of the hot water storage tank 3, a heat source energy storage circulating water pump 6, a multi-energy input module 1, and a secondary heat supplement module 2 connected in series or parallel via pipelines. In this circuit, the heat source energy storage circulating water pump 6 draws cooler circulating water from the bottom of the hot water storage tank 3 and drives it to the multi-energy input module 1. As an optional implementation, the multi-energy input module 1 can be one or more air source heat pump units. The air source heat pump uses input electrical energy to absorb low-grade heat energy from the air to heat the circulating water. After initial heating by the multi-energy input module 1, the water then flows to the secondary heat supplement module 2 connected in series. In this embodiment, the secondary heat supplement module 2 can be an electric boiler. Under specific operating conditions, such as when the heating capacity of the air source heat pump is insufficient to raise the water temperature to a preset value, the secondary heat supplement module 2 is activated to provide secondary supplementary heating to the water. Finally, the high-temperature hot water, after one or two stages of heating, is transported through pipelines to the upper part of the hot water storage tank 3, thus completing the heat storage process.

[0025] The second closed-loop system is the heating loop, which precisely delivers the heat stored in the hot water storage tank 3 to each building according to user needs. This loop consists of the hot water storage tank 3, the heat release circulation pump 12, and one or more building heating modules connected in parallel via pipelines. In this loop, the heat release circulation pump 12 draws high-temperature hot water stored in the upper part of the hot water storage tank 3 and delivers it to the inlet of each building heating module via the main heating pipeline. After the hot water completes heat exchange inside the building heating module, its temperature decreases, forming low-temperature return water, which then returns to the lower part of the hot water storage tank 3 via the return water main pipeline, thus completing the heating cycle.

[0026] The intelligent heating platform 5, serving as the system's control hub, typically comprises an industrial-grade computer, a programmable logic controller (PLC), various sensors, and corresponding control software. The intelligent heating platform 5 establishes comprehensive electrical connections with all executable components and sensors within the system via wired or wireless communication. These connections include, but are not limited to: connections to the start / stop and speed control interfaces of the heat source energy storage circulating water pump 6 and the heat energy release circulating pump 12; connections to the power regulation interface of the secondary heat supplement module 2; connections to the signal acquisition interfaces of the temperature sensor 10 and water level sensor 11 installed on the hot water storage tank 3; and connections to key actuators (such as the electric regulating valve 13 detailed later) and data acquisition elements (indoor temperature sensor 15) within each building heating module. In this embodiment, all power-consuming devices in the system, including the various energy input modules 1, the secondary heat supplement module 2, the heat source energy storage circulating water pump 6, the heat energy release circulating pump 12, and the intelligent heating platform 5 itself, are powered by the system power supply 20. Among them, the green power grid 17 can be a power grid composed of renewable energy sources such as photovoltaic and wind power, which makes the operation of the entire heating system have lower carbon emissions.

[0027] Preferably, the intelligent regulating device 4 for building heating inlet includes: an electric regulating valve 13, a heat exchanger 16, a single building heating circulation pump 14, and an indoor temperature sensor 15; The heat release outlet of the hot water storage tank 3 is connected to the first inlet of the heat exchanger 16 through a pipeline. The heat release return outlet of the hot water storage tank 3 is connected to the first outlet of the heat exchanger 16 through a pipeline. The second inlet of the heat exchanger 16 is connected to the outlet of the heating pipeline of the building to be heated. The second outlet of the heat exchanger 16 is connected to the inlet of the heating pipeline of the building to be heated. A single building heating circulation pump 14 is installed between the second inlet of the heat exchanger 16 and the outlet of the heating pipeline of the building to be heated. The single building heating circulation pump 14 is connected to the smart heating platform 5 by signal. The single building heating circulation pump 14 is electrically connected to the system power supply 20 through a wire. The electric regulating valve 13 is installed between the heat release outlet of the hot water storage tank 3 and the first inlet of the heat exchanger 16. The electric regulating valve 13 is connected to the smart heating platform 5 via signal. The indoor temperature sensor 15 is installed in the building to be heated, and the indoor temperature sensor 15 is connected to the smart heating platform 5.

[0028] Understandably, each building heating module serves an independent heating area, such as a residential building or a factory. High-temperature hot water from the main heating circuit enters a branch circuit of the module and flows through an electrically controlled regulating valve 13. The opening and closing status of this valve 13 is remotely controlled by the smart heating platform 5 based on the building's actual heating needs. When the regulating valve 13 is instructed to open, the high-temperature hot water continues to flow to the first inlet of the heat exchanger 16. The heat exchanger 16 can be a high-efficiency plate heat exchanger or a shell-and-tube heat exchanger, with two physically isolated flow channels inside. As the high-temperature hot water flows through the first flow channel of the heat exchanger 16, it transfers its heat to the circulating water from the building's internal heating system flowing in the second flow channel. After its own temperature decreases, it flows out from the first outlet and merges into the return water main of the heating circuit. Correspondingly, the second side of the heat exchanger 16 forms an independent, closed internal circulation with the building's own internal heating network (such as underfloor heating coils or radiator systems). The internal circulation is driven by a single building heating circulation pump 14 to ensure that the water in the building can continuously circulate through the heat exchanger 16 for heating and to evenly distribute the heat to each room in the building.

[0029] Preferably, the multiple energy input module 1 includes one or more of the following: air source heat pump, sewage source heat pump, ground source heat pump, industrial waste heat recovery device, and biomass boiler.

[0030] Understandably, in this embodiment, the multiple energy input module 1 consists of a ground source heat pump system and an industrial waste heat recovery device. The ground source heat pump utilizes the relatively stable temperature of soil or groundwater as a heat source and cold source; its operating efficiency is less affected by fluctuations in outdoor air temperature, resulting in a high energy efficiency ratio and stable operation. The industrial waste heat recovery device recovers heat from waste hot water, waste steam, or high-temperature flue gas generated during the production process of nearby factories; this heat recovery is relatively inexpensive. The secondary heat supplement module 2 can still use an electric boiler for deep peak shaving and emergency backup.

[0031] Corresponding to changes in the energy structure, the energy storage control logic of the smart heating platform 5 has also been adjusted to a priority scheduling strategy based on energy cost and availability. When a user determines that heat storage is needed through the smart heating platform 5, the user makes a decision based on a preset priority order. The first priority is the industrial waste heat recovery device. The user first queries the current status of the industrial waste heat source through the smart heating platform 5. If the heating demand is met, the relevant equipment of the industrial waste heat recovery device is activated first to heat the hot water storage tank 3 using this low-cost heat. The second priority is the ground source heat pump. When industrial waste heat is unavailable or insufficient, the user automatically activates the ground source heat pump system as the main heating equipment through the smart heating platform 5. The third priority, and the lowest priority, is the secondary supplementary heating module 2. Only when the industrial waste heat and the ground source heat pump work together and still cannot meet the set heating rate requirements will the smart heating platform 5 activate the electric boiler for supplementary heating.

[0032] Furthermore, users can achieve more refined hybrid operation modes through the smart heating platform 5. For example, when industrial waste heat can only provide a portion of the heat, the platform can calculate the required additional heat and precisely control the operating power of the ground source heat pump, so that the two combine to perfectly meet the demand.

[0033] Through this energy combination optimization and priority scheduling, the system in this embodiment can make intelligent decisions based on the real-time availability and economy of different energy sources, prioritizing the use of low-cost energy, thereby significantly reducing the average operating cost throughout the heating season. This demonstrates the flexibility of the proposed solution in energy integration, enabling it to adapt to project needs under different resource conditions.

[0034] In another alternative embodiment, the multiple energy input module 1 can still be an air source heat pump. However, considering that the heating performance of the air source heat pump will decrease as the outdoor ambient temperature decreases, this embodiment replaces the secondary heat supply module 2 with a gas-fired boiler to cope with severe cold weather. The heating capacity of the gas-fired boiler is not affected by the external ambient temperature and can serve as a powerful and reliable backup heat source.

[0035] The smart heating platform 5 can also connect to the meteorological service center, enabling it to regularly obtain detailed weather forecast data for the future.

[0036] Based on this predictive data, users can execute forward-looking energy storage control logic on the smart heating platform 5. The process is as follows: When weather forecasts indicate a sharp drop in outdoor temperature within the next few hours, even if the current water temperature in the hot water storage tank 3 is still within an acceptable range, the user will activate the heat storage circuit in advance through the smart heating platform 5. First, multiple energy input modules 1 will be activated to economically store heat while the current efficiency is still acceptable. Simultaneously, based on the predicted temperature drop and duration, the additional heat reserve required to cope with extreme low temperatures will be calculated. If it is determined that the air source heat pump alone cannot heat the water tank to a sufficiently safe temperature before the temperature drops, the secondary supplementary heating module 2 will be activated in advance for coordinated heating. The advantage of this predictive control is that it does not passively activate the backup heat source only after severe weather has arrived and the heat source efficiency is extremely low. Instead, it establishes sufficient heat reserves in a more economical way beforehand, thus smoothly coping with the dual challenges of the upcoming peak heating season and the decline in heat source capacity.

[0037] When extreme cold weather actually occurs, the system can provide heating smoothly because the hot water storage tank 3 already contains a large amount of high-temperature hot water. At this time, even if the heating capacity of the air source heat pump drops significantly or even stops, the gas boiler can still serve as the main heat source to supplement the heat storage circuit, ensuring that the water temperature of the hot water storage tank 3 is maintained above a safe level, thereby ensuring uninterrupted heating service for all users.
