Description

Technical Field

[0001] This utility model relates to the field of zero-carbon digital energy supply technology for campus buildings, and in particular to a renewable energy zero-carbon system applied to campuses. Background Technology

[0002] However, traditional campus energy systems rely heavily on traditional power grids. Winter heating is provided by municipal centralized heating, summer cooling relies on central air conditioning units, and domestic hot water is supplied using traditional methods such as electric heating. This not only increases carbon emissions but also makes the campus energy system vulnerable to fluctuations in external supply. Therefore, there is an urgent need for a renewable energy zero-carbon system applicable to campuses to solve the above problems. Utility Model Content

[0003] This utility model discloses a renewable energy zero-carbon system for campuses, aiming to solve the technical problems that traditional campus energy systems rely heavily on the traditional power grid system, use municipal centralized heating for winter heating, rely on central air conditioning units for summer cooling, and use electric heating for domestic hot water supply. These traditional methods not only increase carbon emissions but also make the campus energy system fragile and susceptible to fluctuations in external supply.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A renewable energy zero-carbon system for campuses includes a campus building complex with photovoltaic power generation devices and solar thermal collectors installed on the roofs of the complex, and shallow geothermal wells on the ground. The system also includes a heat pump, an air-source heat pump, an energy storage tank, and a traditional power grid. The photovoltaic power generation devices provide daily electricity to the campus building complex and drive the heat pumps and air-source heat pumps, while the solar thermal collectors supplement the heat to the shallow geothermal wells.

[0006] In this plan, renewable energy replaces traditional energy, and a zero-carbon energy supply system is used for on-site teaching to enhance the high-end teaching experience. In actual use, the electricity generated by the photovoltaic power generation device provides daily electricity for the campus building complex and provides driving power for heat pumps and air source heat pumps. The heat pumps extract heat from shallow geothermal wells and the air source heat pumps extract heat from the air to provide heating, cooling or domestic hot water for the buildings, effectively reducing carbon emissions caused by traditional power supply.

[0007] In a preferred embodiment, a fixed platform is provided on one side of the energy storage tank, and an inlet pipe is connected to the top of the energy storage tank. A diversion frame is installed at one end of the inlet pipe, and two symmetrically distributed processing cylinders are connected to the diversion frame. Fastening buckles are connected to both outer walls of the fixed platform by hinges, and the processing cylinders are connected to the fixed platform through the fastening buckles.

[0008] The energy storage water tank in this solution has a dual-port water inlet. The water can be filtered by connecting two treatment cylinders through the diversion frame, ensuring the quality of the incoming water and facilitating replacement. In actual use, the water inlet is connected to only one of the treatment cylinders on the diversion frame. When the connected treatment cylinder needs cleaning or maintenance, the other treatment cylinder can be connected directly without affecting the normal water inlet process of the energy storage water tank. After the treatment cylinder is maintained, it can be reinstalled within the specified time.

[0009] As described above, a renewable energy zero-carbon system applied to a campus includes a campus building complex. The rooftops of the campus buildings are equipped with photovoltaic power generation devices and solar thermal collectors. Shallow geothermal wells are located on the campus ground. The system also includes a heat pump, an air-source heat pump, an energy storage tank, and a traditional power grid. The photovoltaic power generation devices provide daily electricity to the campus buildings and drive the heat pumps and air-source heat pumps. The solar thermal collectors supplement the heat to the shallow geothermal wells. This renewable energy zero-carbon system for campuses provides a technological advantage by utilizing renewable energy to replace traditional power supply, effectively reducing carbon emissions.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0017] The renewable energy zero-carbon system disclosed in this utility model is mainly applied to scenarios where the campus energy system relies heavily on the traditional power grid system, with municipal centralized heating for winter heating, central air conditioning units for summer cooling, and electric heating for domestic hot water supply. This not only increases carbon emissions but also makes the campus energy system fragile and susceptible to fluctuations in external supply.

[0018] Reference Figure 1 and Figure 2 A renewable energy zero-carbon system for campuses includes a campus building complex 8, with photovoltaic power generation devices 1 and solar thermal collectors 2 installed on the roofs of the campus building complex 8, and shallow geothermal wells 3 installed on the ground of the campus. It also includes a heat pump 4, an air source heat pump 5, an energy storage tank 6, and a conventional power grid 7. The photovoltaic power generation devices 1 provide daily electricity for the campus building complex 8 and drive the heat pumps 4 and 5, while the solar thermal collectors 2 supplement the shallow geothermal wells 3 with heat.

[0019] Specifically, by replacing traditional energy with renewable energy and conducting on-site teaching through a zero-carbon energy supply system, a high-end teaching experience is facilitated. In actual use, the electricity generated by the photovoltaic power generation device 1 provides daily electricity for the campus building complex 8 and provides driving power for the heat pump 4 and the air source heat pump 5. The heat pump 4 extracts heat from the shallow geothermal well 3 and the air source heat pump 5 extracts heat from the air to provide heating, cooling or domestic hot water for the buildings.

[0020] The energy storage tank 6 has a capacity of 5-10 cubic meters and is equipped with a temperature sensor.

[0021] Among them, the traditional power grid 7 is connected to the campus power system through a smart switch, which can control different circuits to supply power to the campus when there is sufficient sunlight and insufficient sunlight.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5In a preferred embodiment, a fixed platform 9 is provided on one side of the energy storage tank 6, and an inlet pipe 12 is connected to the top of the energy storage tank 6. A diversion frame 10 is installed at one end of the inlet pipe 12, and two symmetrically distributed treatment cylinders 13 are connected to the diversion frame 10. Fastening buckles 16 are connected to both outer walls of the fixed platform 9 by hinges, and the treatment cylinders 13 are connected to the fixed platform 9 by the fastening buckles 16.

[0023] Specifically, the energy storage water tank 6 in this solution is equipped with a dual-hole water inlet. The water can be filtered by connecting the treatment cylinders 13 through the diversion frame 10, ensuring the quality of the incoming water and facilitating replacement. In actual use, the water inlet is only connected to one of the treatment cylinders 13 on the diversion frame 10. When the connected treatment cylinder 13 needs cleaning and maintenance, the other treatment cylinder 13 can be directly connected without affecting the normal water inlet process of the energy storage water tank 6. After the treatment cylinder 13 is maintained, it can be reinstalled within the specified time.

[0024] Both treatment cylinders 13 are installed on the diverter 10 by screw connection. The treatment cylinder 13 is provided with a pre-filter layer 14 and a post-filter layer 15. The pre-filter layer 14 is made of melt-blown filter element, and the post-filter layer 15 is made of coconut shell activated carbon filter element material.

[0025] It should be noted that the free end of the fastener 16 is fixed to the fixed platform 9 by screw connection. The inner wall of the fastener 16 is provided with an elastic pad 17 made of elastic material. When the fastener 16 is locked to the fixed platform 9, the elastic pad 17 can support and press against the processing cylinder 13 to ensure the stable installation of the processing cylinder 13.

[0026] Reference Figure 2 and Figure 5 In a preferred embodiment, each of the two treatment cylinders 13 is screwed to a connector 11, and an inlet composite cylinder 18 is installed on the connector 11. The inlet composite cylinder 18 is provided with composite calcium slow-release filter media. The connector 11 is used to connect to an external water pipe. Through the inlet composite cylinder 18, the calcium and magnesium ions can be interfered with from the inlet through the lattice distortion effect, thereby inhibiting the formation of scale in the energy storage tank 6.

[0027] Working principle: During the day when there is sufficient sunlight, the photovoltaic power generation device 1 provides daily electricity for the campus building complex 8, and provides driving power for heat pump 4 and air source heat pump 5. The heat pump 4 extracts heat from the shallow geothermal well 3 and the air source heat pump 5 extracts heat from the air to provide heating, cooling or domestic hot water for the campus building complex 8. When there is insufficient sunlight or no sunlight at night, the traditional power grid 7 provides driving power for the campus building complex 8 and its equipment. Under normal circumstances, the traditional power grid 7 serves as a backup power source. In summer, in order to supplement the heat lost by the shallow geothermal well 3 in winter, the solar thermal collector 2 is used as a supplementary heat source for the shallow geothermal well 3. The entire system incorporates an energy storage tank 6, which increases the stability of heating and cooling.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
