Description

Technical Field

[0001] The utility model relates to the technical field of green energy-saving of buildings, and more specifically to a decentralized building clean energy supply system considering building energy-saving transformation. Background Art

[0002] In order to further improve people's quality of life and increase the utilization rate of renewable energy on the user side, my country has implemented the "coal to electricity" clean heating project in various regions in the north, which has greatly reduced the consumption of fossil energy in the winter heating process. However, the current "coal to electricity" project mainly uses user-side heating equipment as the main means, which has the following shortcomings:

[0003] (1) The winter heating load of decentralized buildings in the north is too high, which leads to the selection of a larger capacity for heating equipment, thus greatly increasing the initial investment and operating costs of the heating equipment.

[0004] (2) There are many dispersed residents in the north. In addition to the high demand for building heating in winter, these residents also have a large demand for electricity in other seasons to meet their daily production and life.

[0005] (3) After the implementation of the “coal to electricity” policy, residents’ energy consumption throughout the year is still mainly based on municipal electricity, which cannot guarantee the cleanliness of energy consumption.

[0006] The use of distributed functional equipment can solve the above problems to a certain extent. Distributed energy supply equipment refers to system equipment that uses various renewable energy and clean energy to perform energy conversion, supply and optimization management at the user end. These devices usually adopt a miniaturized and modular design, which can achieve efficient energy utilization and distributed energy management at the user end.

[0007] However, most residents do not have the ability to judge and handle the faults of the above-mentioned distributed energy supply equipment, so it is necessary to provide residents with a set of professional monitoring and fault service systems to reduce the load on the user side while achieving clean energy supply for the buildings where residents living in scattered areas in the north live. This is of great significance for reducing residents' energy costs and improving the cleanliness of electricity at the end of the power grid. Utility Model Content

DETAILED DESCRIPTION

[0040] This embodiment proposes a decentralized building clean energy supply system considering building energy-saving transformation. Figure 1 The system includes a power supply side subsystem for generating, storing and outputting electric energy and for collecting, storing and outputting heat, a load side subsystem for consuming the electric energy and heat output by the power supply side subsystem, an electric energy metering device 10 for counting the amount of electricity flowing out and into the distributed building clean energy supply system, and a service side comprehensive monitoring subsystem 15 for managing and real-time monitoring the electric energy metering device 10, the power supply side subsystem and the load side subsystem.

[0041] The energy supply side subsystem includes a photovoltaic device 12 for generating, storing and outputting electric energy, and a heat pump energy storage device 13 for collecting, storing and outputting heat; the load side subsystem includes a building body and a building terminal energy-consuming device 14 installed in the building body for consuming the electric energy and heat output by the energy supply side subsystem.

[0042] The decentralized building clean energy supply system mainly improves the current "coal to electricity" solution formed by replacing user-side heating equipment from three aspects: load side, energy supply side and service side.

[0043] In terms of the load-side subsystem, this embodiment mainly achieves the reduction of the energy load of the building body and the terminal energy-consuming equipment of the decentralized building through energy-saving transformation.

[0044] The building terminal energy-using equipment 14 is installed in the building body, including residential electrical devices and heat devices, wherein the electrical devices include household appliances 5 and production appliances 6, and the heat devices are heating heat exchangers 9, which are at least one of heating radiators and floor coil heat exchangers. For household appliances and production appliances installed in the building body, energy-saving appliances should be selected.

[0045] The energy-saving transformation of the building body of the decentralized building includes external wall and roof insulation and door and window transformation, etc. Through the above energy-saving and heat-preservation transformation of the building body envelope structure, the energy consumption of the heating heat exchanger 9 is effectively reduced.

[0046] In terms of the energy supply subsystem, by building a distributed energy supply system of "photovoltaic + heat pump", clean energy substitution for the building's annual electricity and heat demand can be achieved. Specifically, it includes:

[0047] (1) Use photovoltaic equipment for power supply. Photovoltaic equipment is installed on the roofs of decentralized buildings and idle land, and includes a photovoltaic power generation device 1, a chemical energy storage device 2, and a grid-connected inverter 3. Among them, the chemical energy storage device 2 is a lithium metal battery or a lithium manganese oxide battery.

[0048] The photovoltaic power generation device 1 and the chemical energy storage device 2 are connected to the input end of the DC side of the grid-connected inverter 3, and the three together constitute the photovoltaic device 12. The output end of the AC side of the grid-connected inverter 3 is the power transmission end of the photovoltaic device 12, and it is also the power transmission end of the energy supply side subsystem. The electric energy generated by the photovoltaic power generation device and the electric energy stored in the chemical energy storage device are output through the output end of the AC side of the grid-connected inverter 3. The power transmission end of the photovoltaic device 12 is electrically connected to the power receiving end of the household appliance 5 and the power receiving end of the production appliance 6 respectively.

[0049] (2) The power supply to decentralized buildings is realized in the form of "self-generation for own use, and surplus power is connected to the grid". The power transmission end of the photovoltaic device 12 (i.e., the output end of the AC side of the grid-connected inverter 3) is also electrically connected to the first end of the power metering device 10, and the second end of the power metering device 10 is connected to the large power grid 11. When the decentralized building clean energy supply system provided in this embodiment is in operation, the power output from the power transmission end of the photovoltaic device 12 is preferentially supplied to each power-consuming device in the system. If there is excess power, it can be "connected to the grid" through the power metering device 10. In addition, when the power output of the photovoltaic device 12 is insufficient and the power-consuming devices in the decentralized building clean energy supply system are short of power, users can choose to purchase electricity from the large power grid 11.

[0050] (3) Use the heat pump energy storage device 13 to meet the winter heating needs of decentralized buildings. The heat pump energy storage device 13 refers to a heat pump device and its supporting heat storage device selected for building heating according to the actual scene conditions of the building. In this embodiment, the heat pump device 4, the heat storage device 7 and the circulating liquid pump device 8 together constitute the heat pump energy storage device 13, and the power transmission end of the photovoltaic device 12 is also electrically connected to the power receiving end of the heat pump energy storage device 13. The heat pump device 4 and the circulating liquid pump device 8 are powered by the photovoltaic device 12, and the electric energy flows from the output end of the AC side of the grid-connected inverter 3 constituting the photovoltaic device 12 to the heat pump device 4 and the circulating liquid pump device 8. The heat pump device 4 and the heat storage device 7 are fluidly connected to each other by means of a pipeline to form a heat pump working medium circulation loop, and the heat pump working medium continuously flows in the heat pump working medium circulation loop to realize heat exchange between the heat pump device 4 and the heat storage device 7. The heat storage device 7 and the heating heat exchanger 9 exchange heat through circulating water (i.e., heat dissipation liquid), and the circulating water is circulated through the circulating liquid pump device 8. That is, a heat dissipation circulation loop is formed between the heat storage device 7, the circulating liquid pump device 8 and the heating heat exchanger 9. The heat dissipation circulation loop and the heat pump working medium circulation loop are independent of each other (that is, there is no fluid conduction relationship between the two), but heat exchange will occur between the two.

[0051] In the heat storage device 7, heat exchange will occur between the heat pump working fluid in the heat pump working fluid circulation loop and the water in the heat dissipation circulation loop. Specifically, the heat carried by the heat pump working fluid heats the water in the heat dissipation circulation loop, and the heated water flows along the heat dissipation circulation loop to the heating heat exchanger 9 under the action of the circulating liquid pump device 8; after the water releases the heat it carries at the heating heat exchanger 9, it flows back to the heat storage device 7 under the action of the circulating liquid pump device 8, and this cycle is repeated, so that heat is continuously transferred from the energy supply side subsystem to the load side subsystem.

[0052] The heat pump device 4 is any one of an air source heat pump, a solar heat pump and a soil source heat pump; the heat storage device 7 is a water heat storage device or a phase change heat storage device.

[0053] In this embodiment, a service-side comprehensive monitoring subsystem 15 for monitoring the distributed building clean energy supply system is established by using technologies such as the Internet of Things and cloud computing. The service-side comprehensive monitoring subsystem 15 can be used to monitor the operating status of one or more distributed building clean energy supply systems.

[0054] The service-side integrated monitoring subsystem 15 includes energy management equipment, energy supply system cloud platform, energy supply system control equipment, energy supply system execution equipment, communication equipment and information collection equipment for collecting operating status information of various equipment in the distributed building cleaning energy supply system.

[0055] like Figure 2As shown, communication links are respectively formed between the energy management device and the energy supply system cloud platform, between the energy management device and the energy supply system control device, between the energy management device and the functional system execution device, and between the energy management device and the information collection device, and the communication device is installed in the communication link. The communication device is used to transmit operating status information and control instructions (including control instructions issued by the energy supply system cloud platform and control instructions issued by the energy management device) in the communication link.

[0056] Specifically, the information collection equipment is mainly responsible for collecting the operating status information of the chemical energy storage device 2, the grid-connected inverter 3, the electric energy metering equipment 10, the heat pump energy storage equipment 13, the building body and the building terminal energy-consuming equipment 14.

[0057] With the help of communication equipment, the information collection equipment sends the collected operating status information of each device and equipment to the energy management equipment. The energy management equipment is used to receive the operating status information sent by the information collection equipment, analyze the operating status information, generate control instructions, and send the control instructions to the energy supply system control equipment and the energy supply system execution equipment. In addition, the energy management equipment can also be used to receive control instructions from the energy supply system cloud platform, and send these control instructions to the energy supply system control equipment and the energy supply system execution equipment.

[0058] There are telecommunication connections between the energy supply system control device and the energy supply side subsystem, between the energy supply system control device and the load side subsystem, and between the energy supply system control device and the electric energy metering device 10. According to the received control instructions, the energy supply system control device can directly control the devices in these subsystems and the electric energy metering device 10. The energy supply system execution device is used to control the on-off of the power lines in the decentralized building clean energy supply system, adjust the flow rate of the heat pump working medium circulation loop, and adjust the flow rate of the heat dissipation circulation loop according to the received control instructions.

[0059] The information collection device collects the operating status information of the decentralized building clean energy supply system, and transmits the operating status information to the energy management system with the help of the communication device, so as to realize real-time monitoring, fault analysis and auxiliary operation and maintenance of the system. In addition, with the help of the communication device, the energy supply system cloud platform can also send control instructions to the energy supply system control device and the energy supply system execution device (via the energy management device) to realize the control of the decentralized building clean energy supply system.

[0060] The decentralized building clean energy supply system proposed in this embodiment adopts an operation mode that gives priority to meeting the heating needs of the building, that is, photovoltaic power generation and the storage capacity of the chemical energy storage device 2 are preferentially used to supply the heat pump device to work, so as to preferentially generate heat energy to meet the heating needs. If the photovoltaic self-generated electricity is insufficient, electricity is purchased from the large power grid 11 for supplementation. At this time, the electricity purchased from the large power grid 11 flows through the power metering device 10, and then flows to the power receiving end of the heat pump device 4, the power receiving end of the circulating liquid pump device 8, the power receiving end of the household appliance 5, and the power receiving end of the production appliance 6, which are electrically connected to the third end of the power metering device 10, through the third end of the power metering device 10. In some other embodiments, an electric heater can be installed in the heat storage device 7. The third end of the power metering device 10 can also be electrically connected to the power receiving end of the heat storage device 7 with an electric heater installed inside. In extremely cold weather, if the heat generation of the heat pump is not enough to meet the heating needs, the electric heater in the heat storage device 7 can consume the heat generated by the electric energy to heat the heating heat exchanger 9.

[0061] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
