Description

Technical Field

[0001] This application relates to the field of new energy technology, and more specifically, to a distributed heating system that combines a heat collection tube with photovoltaic and electric auxiliary heating. Background Technology

[0002] In the current field of solar heating, a new energy technology in my country, although solar energy is widely used as a clean and renewable energy source, traditional solar heating systems still have some significant shortcomings in practical applications.

[0003] First, the heating capacity of traditional solar heating systems is heavily dependent on sunlight conditions. On sunny days, the system can effectively collect solar energy for heating; however, during cloudy or rainy weather or at night, the intensity of sunlight significantly decreases, leading to a substantial drop in the system's heating capacity and making it unable to meet users' continuous heating needs. This over-reliance on natural conditions limits the stability and reliability of solar heating systems, especially in northern regions during winter or in areas with frequent cloudy or rainy weather. Second, traditional solar heating systems have low efficiency in heat storage and distribution. Heat storage and distribution are crucial components of a heating system, but traditional systems suffer from significant heat loss in this area. Low heat exchange efficiency between the water tank and radiators, along with a lack of effective heat retention measures, results in considerable heat waste during transfer, thus affecting the overall energy efficiency of the system. Furthermore, traditional solar heating systems have low levels of intelligence; they cannot respond to changes in the external environment in real time, leading to low user comfort and hindering optimal energy utilization.

[0004] These shortcomings not only limit the market competitiveness of solar heating systems but also hinder their potential in energy conservation and emission reduction. Therefore, the research and application of new energy heating technologies urgently need innovation and improvement to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a distributed heating system combining solar collectors with photovoltaic and electric auxiliary systems. This aims to improve the heating capacity of traditional solar heating systems, which are heavily reliant on sunlight conditions. While the system can effectively collect solar energy for heating in sunny weather, its heating capacity drops significantly during cloudy or rainy weather or at night, failing to meet users' continuous heating needs. This excessive dependence on natural conditions limits the stability and reliability of solar heating systems, especially in northern regions with frequent winters or prolonged periods of cloudy or rainy weather. Secondly, traditional solar heating systems suffer from low efficiency in heat storage and distribution. Heat storage and distribution are crucial components of heating systems, but traditional systems suffer from significant heat loss in this area. Low heat exchange efficiency between the water tank and radiators, coupled with a lack of effective heat retention measures, leads to substantial heat waste during transfer, affecting the overall energy efficiency of the system. Furthermore, traditional solar heating systems have low levels of intelligence, failing to respond in real-time to changes in the external environment, resulting in low user comfort and hindering optimal energy utilization.

[0007] This application provides a distributed heating system combining solar collectors with photovoltaic and electric auxiliary heating, including a solar collector, a photovoltaic DC power heater, an insulated water tank, radiators, a central controller, radiator water pumps, AC electric heaters, and a collector hot water exchange pump. A second water guide pipe is installed between the outlet of the insulated water tank and the inlet of the radiator water pump, a first water guide pipe is installed between the outlet of the radiator water pump and the inlet of the radiator, and a third water guide pipe is installed between the outlet of the radiator and the inlet of the insulated water tank.

[0008] A fourth water guide pipe is installed between the outlet of the insulated water tank and the inlet of the solar collector hot water pump; a fifth water guide pipe is installed between the outlet of the solar collector hot water pump and the inlet of the solar collector; a sixth water guide pipe is installed between the outlet of the solar collector and the inlet of the insulated water tank; the AC electric heater and the radiator are electrically connected together; different AC electric heaters are electrically connected to the insulated water tank; the photovoltaic DC power heater and the radiator are electrically connected together; and the central controller and the photovoltaic DC power heater are electrically connected together.

[0009] In one embodiment of this application, a water pipe and a solenoid valve are also included. One end of the water pipe is installed together with the inlet of the insulated water tank, and the solenoid valve is disposed on the water pipe.

[0010] In one embodiment of this application, a liquid level sensor is provided on the insulated water tank, and the solenoid valve and the liquid level sensor are electrically connected together.

[0011] In one embodiment of this application, the solar collector, the photovoltaic DC power heater, the radiator, the radiator water pump, the AC heater, the solenoid valve, and the collector hot water pump are all electrically connected to the central controller and connected via control lines.

[0012] In one embodiment of this application, the insulated water tank is provided with multiple AC electric heaters, which can directly heat the insulated water tank.

[0013] In one embodiment of this application, an air vent and a water inlet are installed on the sixth water pipe at the outlet end of the solar collector.

[0014] In one embodiment of this application, temperature sensors are provided on the solar collector, the insulated water tank, and the radiator.

[0015] The beneficial effects of this application are as follows: The distributed heating system combining solar collectors, photovoltaics, and electric auxiliary heating, obtained through the above design, ensures that, under suitable heat collection conditions, the heating medium from the solar collectors is efficiently pumped into the insulated water tank via a heat exchange pump. This not only accelerates heat collection but also improves heat storage efficiency. When the user turns on the heating mode, the radiator pump starts, delivering hot water from the insulated water tank to the radiators for heat exchange. This process ensures effective heat transfer, improving heating efficiency and comfort. During the process of the solar collector collecting heat from the insulated water tank, the heat exchange pump between the insulated water tank and the radiators remains closed. This effectively avoids unnecessary heat waste, thereby improving the overall thermal energy utilization rate and economy of the system. The electricity generated by the photovoltaic DC power heater is used to heat the radiators. When the light intensity decreases, the output current of the photovoltaic panel weakens, and the radiator temperature drops below the minimum value, the heat exchange pump of the collector between the insulated water tank and the radiator starts. This intelligent adjustment mechanism ensures the stability and reliability of the heating system while reducing unnecessary energy consumption. When the radiator temperature drops below the minimum temperature, the AC electric heater automatically starts, quickly heating the radiator to the specified temperature and maintaining a constant temperature. This automatic adjustment function ensures a constant and comfortable indoor temperature while avoiding energy waste caused by overheating. Attached Figure Description

[0024] Please see Figures 1-4This application provides a technical solution: a distributed heating system combining solar collectors, photovoltaics, and electric auxiliary heating, including a solar collector 110, a photovoltaic DC power heater 120, an insulated water tank 130, radiators 140, a central controller 150, a radiator water pump 160, an AC electric heater 190, and a collector hot water exchange pump 194. A second water pipe 180 is installed between the outlet of the insulated water tank 130 and the inlet of the radiator water pump 160. A first water guide pipe 170 is installed between the outlet of the radiator 140 and the inlet of the radiator 140. A third water guide pipe 191 is installed between the outlet of the radiator 140 and the inlet of the insulated water tank 130. The system also includes a water pipe 192 and a solenoid valve 193. One end of the water pipe 192 is installed together with the inlet of the insulated water tank 130. The solenoid valve 193 is installed on the water pipe 192. The installation of the water pipe 192 and the solenoid valve 193 facilitates the automatic replenishment of water into the insulated water tank 130.

[0025] A fourth water pipe 195 is installed between the outlet of the insulated water tank 130 and the inlet of the solar collector hot water pump 194; a fifth water pipe 196 is installed between the outlet of the solar collector hot water pump 194 and the inlet of the solar collector 110; a sixth water pipe 197 is installed between the outlet of the solar collector 110 and the inlet of the insulated water tank 130; an AC electric heater 190 and a radiator 140 are electrically connected together; different AC electric heaters 190 and the insulated water tank 130 are electrically connected together; a photovoltaic DC power heater 120 and a radiator 140 are electrically connected together; and a central controller 150 and a photovoltaic DC power heater 120 are electrically connected together.

[0026] A liquid level sensor is installed on the insulated water tank 130. The solenoid valve 193 and the liquid level sensor are electrically connected together. The liquid level sensor facilitates the monitoring of the water level in the insulated water tank 130. The solar collector 110, photovoltaic DC power heater 120, radiator 140, radiator water pump 160, AC heater 190, solenoid valve 193 and collector hot water pump 194 are all electrically connected to the central controller 150 and connected through control lines. Multiple AC heaters 190 are installed on the insulated water tank 130. Multiple AC heaters 190 can directly heat the insulated water tank 130. An air vent valve and a water inlet are installed on the sixth water pipe 197 at the outlet of the solar collector 110. Temperature sensors are installed on the solar collector 110, the insulated water tank 130 and the radiator 140.

[0027] Specifically, the working principle of this distributed heating system combining solar collectors, photovoltaics, and electric auxiliary heating is as follows: During operation, temperature sensors installed on the solar collector 110, insulated water tank 130, and radiators 140 monitor the temperatures of the solar collectors 110, insulated water tank 130, and radiators 140 in real time. Based on the data from the temperature sensors, the central controller 150 automatically and intelligently adjusts the operating status of the solar collector hot water pump 194, the photovoltaic DC power heater 120, and the AC electric heater 190 to maintain a constant indoor temperature. When the output current of the photovoltaic DC power heater 120 decreases and the temperature of the radiator 140 falls below the set value, the central controller 150 intelligently activates... The radiator water pump 160 between the insulated water tank 130 and the radiator 140 stops supplying heat to the radiator 140 when the temperature of the insulated water tank 130 falls below a set minimum value. When the temperature of the radiator 140 falls below the set minimum value, the central controller 150 automatically starts the AC electric heater 190 to heat the radiator 140 to a specified temperature and maintain it at a constant temperature. At night or when there is insufficient sunlight, the central controller 150 automatically starts the AC electric heater 190 on the insulated water tank 130 to heat the insulated water tank 130, ensuring continuous heating. This distributed heating system, which combines solar collectors with photovoltaic and electric auxiliary systems, can achieve solar energy collection when the collection conditions are met. The heating medium from the solar collector tubes on the solar collector 110 is efficiently pumped into the insulated water tank 130 via the solar collector hot water pump 194. This not only accelerates heat collection but also improves heat storage efficiency. When the user turns on the heating mode, the radiator pump 160 starts, sending the hot water from the insulated water tank 130 to the radiator 140 for heat exchange. This process ensures effective heat transfer, improving heating efficiency and comfort. During the heat collection process from the solar collector 110 to the insulated water tank 130, the solar collector hot water pump 194 between the insulated water tank 130 and the radiator 140 remains closed, effectively avoiding unnecessary heat waste and thus improving the overall system's heat energy utilization. Efficiency and economy: The electricity generated by the photovoltaic DC power heater 120 is used to heat the radiator 140. When the light intensity decreases, the output current of the photovoltaic panel weakens, and the temperature of the radiator 140 drops below the minimum value, the heat exchange pump 194 between the insulated water tank 130 and the radiator 140 starts. This intelligent adjustment mechanism ensures the stability and reliability of the heating system while reducing unnecessary energy consumption. When the temperature of the radiator 140 drops below the minimum temperature, the AC electric heater 190 automatically starts, quickly heating the radiator 140 to the specified temperature and maintaining a constant temperature. This automatic adjustment function ensures a constant and comfortable indoor temperature while avoiding energy waste caused by overheating.

[0028] It should be noted that the specific models and specifications of the solar collector 110, photovoltaic DC power heater 120, insulated water tank 130, radiator 140, central controller 150, radiator water pump 160, AC electric heater 190, solenoid valve 193, and collector hot water pump 194 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
