Description

Technical Field

[0001] The present invention relates to the technical field of solar energy utilization, and in particular to an integrated solar energy heating system integrating solar energy heat collection, heat exchange, boiler auxiliary heating and intelligent control. Background Art

[0002] With the energy crisis and the increasing awareness of environmental protection, solar energy, as a clean and renewable energy source, has been widely used in heating and hot water supply. However, the existing solar heating systems often have problems such as complex structure, low efficiency, and insufficient intelligence, which makes it difficult to meet the needs of modern families for efficient, convenient, and intelligent heating. Therefore, it is particularly important to develop an integrated solar heating system with compact structure, high efficiency, energy saving, and intelligent control.

[0003] For example, the patent with publication number CN106440403A solves the problem of producing hot water even when there is no sun. At the same time, the temperature of the water output by solar energy can also be adjusted, which improves the user experience and conforms to the future development trend. However, it lacks components such as the electric gate valve 20 that can flexibly switch the heating circuit and can realize flexible switching of multiple heating modes. There may be limitations in the diversity of heating methods, and the heating circuit cannot be flexibly adjusted according to different energy conditions, such as whether solar energy is sufficient or not, whether boiler assistance is needed, etc., resulting in unreasonable energy utilization and insufficient heating stability.

[0004] The patent with publication number CN107388336A reduces heat loss by controlling the circulation of water in the solar collector and improves the safety of the solar heating system. However, the integration of components is not perfect, and the components are relatively independent or the connection is not smooth. It may be difficult to achieve seamless connection between solar energy and boiler heating and flexible adjustment of the heating circuit as efficiently as this patent. The coordination of the overall system is slightly inferior, and its pipelines are not optimized, which may lead to increased heat loss and more heat loss during the transfer process, affecting the final heating effect and the effective utilization of energy.

This layout design can make the heat exchange inside the heat exchanger 7 more efficient, reduce heat loss, and improve the overall performance of the system.

[0026] As an improvement, the water tank 1 is a stainless steel insulated water tank. The stainless steel material has good corrosion resistance and heat preservation performance, which can effectively maintain the temperature of the water in the water tank, reduce heat loss, and extend the service life of the water tank.

[0027] As an improvement, the first water replenishment tank 12 is made of stainless steel or iron. A liquid level tube 2 is provided on one side of the first water replenishment tank 12. The liquid level tube 2 can display the water level in the first water replenishment tank in real time, so as to facilitate timely replenishment of water and ensure the normal operation of the solar thermal collection circulation system.

[0028] As an improvement, the size of the solar double-pass vacuum collector tube 11 is φ58mm*1800mm, one is installed every 30mm, and so on, with 10 tubes in each group. This specification of solar double-pass vacuum collector tubes has a high thermal collection efficiency, can fully absorb solar energy, convert it into thermal energy, and provide sufficient heat for the heating system.

[0029] As an improvement, a heating tube is provided inside the heat exchanger 7. The heating tube is a stainless steel threaded tube of φ25mm, and the heating medium is heat transfer oil. The stainless steel threaded tube has a large surface area, which can increase the contact area with the heat transfer oil and improve the heat transfer efficiency.

[0030] As an improvement, the solar double-pass vacuum collector tubes 11 are installed in groups, with five groups forming a parallel group. The five collector groups share a base bracket 21. This group installation method can improve the solar energy collection efficiency and facilitate installation and maintenance.

[0031] As an improvement, the base bracket 21 is made of square steel, and is divided into a bottom rod 22, a support rod 23 and an adjustment rod 24. The bottom rod 22 and the support rod 23 are hingedly connected, and the support rod 23 and the adjustment rod 24 are hingedly linked. The adjustment rod 24 is a double-section telescopic tube, which is fixed and locked with bolts. The bottom rod 22, the support rod 23 and the adjustment rod 24 form a triangle after being locked. The adjustable bracket of the solar heat collection group is made of 40*50*2mm square steel. The oblique support rod is retractable, which is convenient for adjusting the elevation angle and maintenance. The base bracket 21 of this structure has good stability and adjustability, and can be flexibly adjusted according to different installation sites and solar irradiation angles, ensuring that the solar double-pass vacuum heat collection tube 11 can receive sunlight to the maximum extent and improve the utilization rate of solar energy.

[0032] As an improvement, the control box is composed of an AC220V circuit breaker, two AC220V AC contactors, a dual temperature controller, an AC220V relay, and a terminal block.

[0033] L (live wire) and N (neutral wire)

[0034] L and N are the power supply lines, which provide power to the entire control box.

[0035] Heating circulation pumps and energy storage circulation pumps

[0036] The heating circulation pump and the energy storage circulation pump are connected to the circuit respectively, and they are connected to other components in the control box through their own lines. The function of these pumps is to realize the water circulation in the heating and energy storage process.

[0037] No. 1 electric valve

[0038] The No. 1 electric valve has two states: "power on, open" and "power on, closed". The opening and closing of the valve is achieved by controlling the power-on state, thereby controlling the on and off of the water flow.

[0039] Electric valve No. 2 and electric valve No. 3

[0040] Both the No. 2 and No. 3 electric valves have an "energized to open" state. They open the valves by energizing them and control the corresponding water flow paths.

[0041] Temperature Sensor

[0042] There are multiple temperature sensors distributed in the circuit to detect the temperature at different locations. The signals of these temperature sensors may be transmitted to the temperature control module for temperature control and regulation.

[0043] Water level detection sensor

[0044] The water level detection sensor is used to detect the water level in the energy storage device to ensure that the water level is within a reasonable range to ensure the normal operation of the system.

[0045] KT temperature control module

[0046] The temperature control module (KT) is the core control part of the entire control box. It receives the temperature signal from the temperature sensor and controls the electric valve and circulation pump according to the preset temperature control strategy to achieve temperature regulation of the heating and energy storage process.

[0047] Control Logic

[0048] The control logic of the entire circuit is based on the instructions of the temperature control module. The temperature control module determines the opening and closing of the electric valve and the start and stop of the circulation pump according to the temperature detected by the temperature sensor. For example, when the temperature is lower than the set value, the temperature control module may instruct the heating circulation pump to start and open the corresponding electric valve to circulate hot water for heating.

[0049] The control of the energy storage circulation pump and related electric valves is similar. The temperature control module performs comprehensive control based on parameters such as temperature and water level to achieve effective management of the energy storage process.

[0050] Through the above circuit connection and control logic, the energy storage heating control box can effectively realize the automatic control of the heating and energy storage process, ensuring the stable operation of the system and the rational use of energy.

[0051] The advantages of the present invention over the prior art are as follows: the integrated solar heating system described in the present invention has a compact structure, occupies a small area, and is easy to install and maintain. By collecting solar energy through solar double-pass vacuum collector tubes and converting it into thermal energy, combined with auxiliary heating of heat exchangers and boilers, efficient and energy-saving heating effects are achieved. An intelligent control system is adopted, which can automatically adjust the heating mode and heating power according to parameters such as ambient temperature and water temperature, realize intelligent control, and improve the comfort and energy saving of the heating system. The provision of the first water supply tank and the second water supply tank ensures sufficient water in the system, avoiding problems such as insufficient heating or equipment damage due to lack of water.

[0052] Working principle of the invention: This integrated energy storage heating system adopts the principle of solar energy storage heating and boiler heating and energy storage integration

[0053] The heating system is designed for saving coal and protecting the environment. It solves the problem of high heating costs in rural and pastoral areas in winter and is not environmentally friendly. It also solves the problem that coal-fired boilers cannot provide heating at night. It enables farmers and herdsmen to achieve the effect and level of centralized heating. This system can also be applied to the effect of hot water for livestock drinking in winter in the breeding industry. It saves 95% of the cost compared to electric heating water tanks.

[0054] This system does not need to be used with an electric heating system for energy storage and antifreeze. It can save about 80% of energy and achieve 90% of environmental protection indicators. It is a one-time investment with lifelong benefits, with low investment and high efficiency.

[0055] The heating circulation pipeline is connected in series from the upper end of the first tube to the lower end, and then from the lower end of the second tube to the upper end. And so on, until the tenth heat collecting tube forms a group. Because each household needs a different heating area, in order to meet the heating area, solar heat collecting groups can be added according to demand, and each group is connected in parallel. For example: each group has a heating area of ​​15㎡, and a room of 30㎡ needs to install 2 groups of collectors. It can also be increased by 2-4 groups according to the coldness of the place.

[0056] The purpose of boiler retention: When it is cloudy for several consecutive days and there is no sun, the boiler can be started. After the boiler is started, the large circulation heating can be maintained. During the heating process, the circulating water in the energy storage water pipe can be kept warm so as to store energy for the circulating water in the energy storage water tank, thus achieving energy saving effect. When the heating temperature is reached, the coal-fired boiler can be stopped. The energy storage water tank can provide energy storage heating time according to the maximum water storage size of the water storage tank.

[0057] The No. 1 and No. 2 electric gate valves play the role of opening and closing the internal circulation. When the boiler and radiator reach the set temperature for heating, the circulation pump stops working. The No. 1 electric gate valve closes the throttling passage to the heating system circulation, and at the same time opens the No. 2 electric gate valve to connect the heat storage internal circulation pipeline, so that the energy storage tank can maintain energy storage. When the boiler is started on consecutive cloudy days, it also plays this role. The No. 3 electric gate valve is installed on the municipal tap water pipeline to replenish the set water level of the energy storage tank.

[0058] Installation and Debugging

[0059] When installing the integrated solar heating system, first, according to the actual situation of the installation site, select a suitable location to install the solar double-pass vacuum heat collecting tube 11 and its base bracket 21. By adjusting the angles of the bottom rod 22, the support rod 23 and the adjustment rod 24 of the base bracket 21, the solar double-pass vacuum heat collecting tube 11 can face the sun and receive sunlight to the maximum extent. Then connect the water tank 1, the heat exchanger 7, the boiler 14, the radiator 16 and various pipes and valves according to the design requirements to ensure that the connection is tight and there is no water leakage or air leakage. After the connection is completed, the entire system is filled with water, and the tap water is injected into the water tank 1 and other parts that need to be filled with water through the pipeline 1 3 and the electric gate valve 3 6. At the same time, observe the liquid level of the liquid level tube 2 and the first water replenishment tank 12 to ensure that the water capacity meets the normal operation requirements. Then the control box is wired and debugged, and the temperature parameters of the dual temperature controller are set so that it can accurately monitor and control the temperature of the heating system.

[0060] Operation process

[0061] When the sun is abundant during the day, the solar double-pass vacuum heat collection tube 11 absorbs the heat of the sun, heats the water in the pipe 5 9, and the circulation pump 13 is started, so that the hot water circulates between the solar double-pass vacuum heat collection tube 11 and the heat exchanger 7, and the heat is transferred to the water in the pipe 4 8 through the heat exchanger 7. When the water temperature in the pipe 4 8 reaches the set heating temperature, the dual temperature controller controls the electric gate valve 20 to open, the circulation heat pump 17 is started, and the hot water flows to the radiator 16 through the pipe 4 8 and the circulation heat pump 17 to realize solar heating. At the same time, the first water replenishment tank 12 will automatically replenish water according to the water loss in the system to ensure the normal operation of the solar heat collection circulation system.

[0062] When it is cloudy or at night when there is insufficient solar energy, the water temperature will gradually drop. When the water temperature is lower than the set heating temperature, the dual temperature controller will control the electric gate valve 19 to open, start the boiler 14 for heating, and the hot water generated by the boiler 14 will flow to the radiator 16 through the pipe 3 5 and the pipe 7 15 to provide heat for the room. At this time, the electric gate valve 20 will adjust the heating circuit according to the actual situation, so that the system can operate stably and ensure the comfortable indoor temperature.

[0063] During the entire operation process, the control box will monitor the temperature of each part and the status of the electric valve in real time, and accurately control the opening and closing of the electric valve through the auxiliary contacts of the AC contactor, thereby realizing intelligent and automated control of the heating system and improving energy utilization and heating effects.
