[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] In the following description of the invention, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. The term "connected" simply indicates a connection between devices and does not have any special meaning.
[0033] Specific implementation plans such as Figure 1 As shown in FIG, an intelligent heating system for comprehensive utilization of multiple clean energy sources includes a collector, a heater, an expansion valve, a compressor, a heat storage tank, a heat pump unit and an energy storage water tank:
[0034] Normal temperature water is heated in the collector and heater. The collector heats the normal temperature water to a specified range by collecting solar energy. The heater drives the fan to rotate through the wind and generates heat by friction with the normal temperature water inside the heater. After the normal temperature water is heated to a specified range, the heated water is transported to the energy storage tank or heat storage tank through the water supply pipe. The system can realize heat transfer between the collector and the heater through the compressor, reversing valve and expansion valve when the solar radiation conditions or wind conditions are poor. When the solar radiation conditions are poor and the wind conditions are good, the heat generated by the collector can be used for preliminary preheating of the water in the heater, and the heat generated in the collector is throttled by the expansion valve and then flows out as a low-pressure, low-temperature liquid After the liquid heat exchange medium absorbs heat, it forms a low-pressure gaseous heat exchange medium. After the low-pressure gaseous heat exchange medium is pressurized by the compressor, it forms a high-pressure gaseous heat exchange medium. After the high-pressure gaseous heat exchange medium transfers the heat to the heater, it forms a high-pressure liquid heat exchange medium to preheat the water in the heater. After the high-pressure liquid heat exchange medium is throttled by the expansion valve, it forms a low-pressure and low-temperature liquid heat exchange medium to carry out the next heat exchange cycle. When the wind condition is poor and the solar radiation condition is good, the reversing valve is started to change the flow direction of the heat exchange medium. After the expansion valve is throttled, the low-pressure and low-temperature liquid heat exchange medium flowing out absorbs the heat generated in the heater and is pressurized by the compressor, and then transfers the heat to the collector to preheat the water in the collector.
[0035] The heat pump unit cools users in the summer and heats users in the winter through the phase change of the refrigerant. In the summer, when the heat supply from solar energy and wind energy is relatively high, the large amount of waste heat generated by the operation of the intelligent heating system utilizing the comprehensive utilization of multiple clean energy sources and the heat carried by the user's indoor water circulation can be stored underground through the cooperation of the refrigerant circulation and the circulating water circulation in the heat pump unit; in the winter, when the heat supply from solar energy and wind energy is insufficient, the heating water is about 40-60°C, and the temperature of the circulating water is about 15-20°C after heat exchange with the groundwater. The circulating water is pumped into the heat storage tank through the second water pump, and the heat exchange medium in the heat storage tank absorbs the heat of the heating water flowing into the heat storage tank. The heating water that has lost heat is pumped into the collector or heater through the first water pump for a heating cycle. Part of the circulating water after absorbing heat flows into the energy storage tank for heat exchange, and the other part of the circulating water after absorbing heat flows into the heat pump unit, exchanges heat with the refrigerant in the heat pump unit, and transfers heat to the user. The circulating water after heat exchange is returned to the underground and pumped into the heat storage tank by the second water pump for a new heat exchange cycle.
[0036] When the energy storage water tank is in use by the user, the heated water exchanges heat with the tap water inside the energy storage water tank, and the tap water is heated and supplied to the user. The water that loses heat after the heat exchange passes through the water supply pipe and is pumped to the collector or heater by the first water pump to continue the heating cycle; the first water pump is also connected to the make-up water to replenish normal temperature water for the operation of the heating system.
[0037] For specific embodiments, see Figure 2The intelligent heating system for comprehensive utilization of multiple clean energy sources includes a heater 1, a heat collector 2, an expansion valve 8, a compressor 9, a heat storage tank 3, a heat exchange pipe 4, a heat pump unit 6, an energy storage tank 7 and a first water pump 5; the water inlet end of the heat collector 2 and the heater 1 and the water outlet end of the heat storage tank 3 are both connected to the first water pump 5, the first water pump 5 is arranged between the water inlet end of the heat collector 2 and the heater 1 and the water outlet end of the heat storage tank 3, the other end of the first water pump 5 is connected to the supplementary water input port, and a first valve 38 is arranged between the water outlet end of the heat collector 2 and the heater 1 and the water inlet end of the heat storage tank 3. The first valve 38 is an on-off valve for controlling the passage to The water flow of the heat storage tank 3 is circulated or cut off; the water outlet ends of the heat collector 2 and the heater 1 are respectively connected to the water inlet end of the heat storage tank 3 and the water inlet end of the energy storage water tank 7, and the water outlet end of the energy storage water tank 7 is connected to the first water pump 5. In winter, the circulating water exchanges heat with the groundwater and is pumped into the heat storage tank 3 through the second water pump 45. After heat exchange, it is respectively connected to the heat pump unit 6 and the energy storage water tank 7. The circulating water after heat exchange returns to the ground through the heat exchange pipe 4 and is pumped into the heat storage tank 3 through the second water pump 45 for recirculation; in summer, the circulating water is pumped into the heat pump unit through the second water pump, exchanges heat with the refrigerant in the heat pump unit 6, and returns to the ground through the heat exchange pipe 4 after heat exchange;
[0038] Furthermore, the heat storage tank 3, the heat exchange pipe 4, the heat pump unit 6 and the energy storage water tank 7 form a heat exchange loop to supply heat and water to the user; the heat exchange pipe 4 includes a water delivery side and a return water side, the second water pump 45 is arranged on the water delivery side, and three branches are arranged on the water delivery side, branch one is connected to tank body 1 31, branch two is connected to tank body 2 32, and branch three is connected to the heat pump unit 6; branch one is also connected to the energy storage water tank 7 and the heat pump unit 6, and the tank body 1 31 is respectively connected to the energy storage water tank 7 and the heat pump unit 6. The branch line 2 is connected to the return side of the heat exchange pipe 4, the branch line 2 is connected to the tank body 2 32 and then to the return side of the heat exchange pipe 4, and the branch line 3 is connected to the heat pump unit 6 and then to the return side of the heat exchange pipe 4; when the user has a cooling demand in the summer, the branch line 1 is closed, and the branches 2 and 3 are opened, and the heated water and the circulating water work together to provide cooling for the user, and the heat is transferred to the underground for storage; when the user has a heating demand in the winter, the branch line 1 is opened, and the branches 2 and 3 are closed, and the heat is extracted from the underground to provide heating for the user;
[0039] In summer, the operation of the heat collector 2 and the heater 1 generates a large amount of waste heat, and the heated water carries a large amount of waste heat and enters the tank body 1 31, exchanges heat with the liquid heat exchange medium in the tank body 1 31, and the liquid heat exchange medium absorbs a large amount of heat and changes into gas. The gaseous heat exchange medium flows into the tank body 2 32, exchanges heat with the solid heat exchange medium in the tank body 2 32, and the gaseous heat exchange medium loses heat and condenses into liquid and returns to the tank body 1 31. The circulating water is pumped into the tank body 2 32 through the branch 2 by the second water pump 45, and after absorbing the heat stored in the solid heat exchange medium, it returns to the ground through the return water side of the heat exchange pipe 4, exchanges heat with the groundwater, and stores the heat underground. The circulating water after heat exchange continues the heat exchange cycle; the circulating water can also be pumped into the heat pump unit 6 through the branch 3 by the second water pump 45, exchanges heat with the refrigerant in the heat pump unit 6, and the heat absorbed by the user's indoor circulation is stored underground through the circulating water cycle;
[0040] In winter, the heat collector 2 and the heater 1 generate insufficient heat. The circulating water carrying heat is pumped into the tank body 31 through the branch line 1 by the second water pump 45. The circulating water temperature is about 15-20°C, and the heated water temperature is about 40-60°C. The heated water transfers heat to the liquid heat exchange medium in the tank body 31. The liquid heat exchange medium absorbs heat and changes into a liquid-gas mixed heat exchange medium. The liquid-gas mixed heat exchange medium transfers heat to the circulating water. After absorbing heat, part of the circulating water flows into the energy storage tank 7 to exchange heat with the heated water in the energy storage tank 7, and the other part is input into the heat pump unit 6 to transfer heat to the user to provide heating to the user. The circulating water after heat exchange is returned to the ground through the return side of the heat exchange pipe 4 to exchange heat with the groundwater, thus performing a heat exchange cycle.
[0041] The expansion valve 8, the compressor 9, the collector 2 and the heater 1 form a heating loop. The collector 2 and the heater 1 generate heat through solar energy and wind energy. The collector 2 and the heater 1 can be connected in parallel to transport heat to the heat storage tank 3 or the energy storage water tank 7 respectively. The heat generated in the heater 1 or the collector 2 can also be transferred through the expansion valve 8 and the compressor 9 to realize the centralized heating of the heater 1 and the collector 2 in series; the heater 1 is connected with the expansion valve 8 and the compressor 9 respectively, and the collector 2 is connected with the expansion valve 8 and the compressor 9 respectively. A second valve 81 is set between the open end of the expansion valve 8 and the working medium open end of the collector 2 for controlling the inflow or outflow of the working medium in the expansion valve 8. A third valve 91 is set between the open end of the compressor 9 and the working medium open end of the heater 1 for controlling the inflow or outflow of the working medium in the compressor 9. The second valve 81 and the third valve 91 are steering valves that can adjust the flow direction according to the solar radiation conditions or wind conditions. When the solar radiation conditions are poor and the wind conditions are good, the collector 2 cannot generate enough heat to heat the water. The low-pressure and low-temperature liquid heat exchange medium flowing out after the expansion valve 8 is throttled absorbs the heat generated in the collector 2, and after being pressurized by the compressor 9, transfers the heat to the heater 1 to preheat the water in the heater 1. When the solar radiation conditions are good and the wind conditions are poor, the heater 1 cannot generate enough heat to heat the water. The second valve 81 and the third valve 91 are activated to change the flow direction of the heat exchange medium. The low-pressure and low-temperature liquid heat exchange medium flowing out after the expansion valve 8 is throttled absorbs the heat generated in the heater 1, and after being pressurized by the compressor 9, transfers the heat to the collector 2 to preheat the water in the collector 2.
[0042] Furthermore, the heater 1 is provided with a speed detector 14 and a temperature sensor 113. The speed detector 14 controls the second valve 81 and the third valve 91 by detecting the wind force, thereby changing the flow direction of the heat exchange medium and improving the heating efficiency. The temperature sensor 113 detects the temperature of the heated water in the heater 1 and controls the opening of the water outlet. Figure 3As shown, when the solar radiation condition is poor but the wind condition is good, the heat generated by the collector 2 can be used for preliminary preheating of the water in the heater 1. The heat generated in the collector 2 is throttled by the expansion valve 8, and the low-pressure and low-temperature liquid heat exchange medium that flows out absorbs the heat to form a low-pressure gaseous heat exchange medium. After being pressurized by the compressor 9, a high-pressure gaseous heat exchange medium is formed. The high-pressure gaseous heat exchange medium transfers the heat to the heater 1 to form a high-pressure liquid heat exchange medium to preheat the water in the heater 1. The high-pressure liquid heat exchange medium is throttled by the expansion valve 8 to form a low-pressure gaseous heat exchange medium. The low-pressure, low-temperature liquid heat exchange medium is compressed to carry out the next heat exchange cycle; when the wind conditions are poor but the sunlight conditions are good, the second valve 81 and the third valve 91 are activated to change the flow direction of the heat exchange medium. The low-pressure, low-temperature liquid heat exchange medium flowing out after the expansion valve 8 throttles absorbs the heat generated in the heater 1, and after being pressurized by the compressor 9, the heat is transferred to the collector 2 to preheat the water in the collector 2; if the wind conditions are good and the sunlight conditions are good, the temperature sensor 113 controls the water outlet to open, and the heated water is transported to the energy storage tank 7;
[0043] The heat pump unit 6 includes a condenser 61, an evaporator 62, a second compressor 63 and a reversing valve 64. The condenser 61, the second compressor 63, the evaporator 62 and the reversing valve 64 are connected end to end and connected in sequence. The refrigerant circulates in it. In summer, the second compressor 63 works on the refrigerant. The refrigerant evaporates and absorbs heat in the evaporator 62, and absorbs the heat carried by the user's indoor water circulation into the refrigerant. The refrigerant circulates through the condenser 61 to condense the refrigerant, realizing heat exchange. The heat is transported to the underground storage through the circulating water heat exchange. After heat exchange, the indoor water circulates to the user. The refrigerant is cooled and delivered to the user; in winter, the compressor 2 63 works on the refrigerant and the reversing valve 64 is used to reverse the flow direction of the refrigerant. The heat stored in the ground and the heat generated by the operation of the collector 2 and the heater 1 are transferred to the heat pump unit 6 through the circulating water. The circulating water after absorbing the heat exchanges heat with the refrigerant in the condenser 61, and the refrigerant evaporates and absorbs heat. The refrigerant after absorbing the heat exchanges heat with the indoor water in the evaporator 62 to transfer the heat to the user, thereby providing heating for the user; the water that loses the heat returns to the ground, exchanges heat with the groundwater, and is pumped into the heat accumulator 3 by the second water pump 45 for circulation.

[0050] The specific working process of the intelligent heating system with comprehensive utilization of multiple clean energy sources is as follows:
[0051] According to the solar radiation conditions or wind conditions, the expansion valve 8 and the compressor 9 are coordinated to make the normal temperature water pass through the heater 1 to generate heat by friction or the collector 2 absorbs solar energy to become higher temperature water. The higher temperature water is discharged from the water outlet 1307 of the heater 1 or the water outlet of the collector 2, and transported to the heat storage tank 3 or the energy storage tank 7 through the water supply pipeline. The energy storage tank 7 exchanges heat with the user's tap water to provide domestic hot water for the user. The water that loses heat after the heat exchange is pumped into the heater 1 or the collector 2 by the first water pump 5 for heating circulation.
[0052] If the system generates more waste heat in summer, the first valve 38 is activated, and the heated water enters the tank body 1 31. The heat of the heated water is transported to the tank body 2 32 through the phase change of the liquid heat exchange medium. The circulating water absorbs the heat and returns to the ground to store the heat underground. In summer, users need cooling. The compressor 2 63 in the heat pump unit 6 works on the refrigerant. The refrigerant evaporates and absorbs heat in the evaporator 62, and the heat carried by the user's indoor circulation is absorbed into the refrigerant. The refrigerant circulates through the condenser 61 to condense the refrigerant, and the heat is transferred to the underground for storage through the circulating water heat exchange. After the heat exchange, the indoor water circulates to deliver cold air to the user. If the system generates less heat in winter, the first valve 38 is activated, and the heated water flows into the tank body 1 31. In tank 131, users need heating in winter, compressor 2 63 works on the refrigerant, and uses reversing valve 64 to reverse the flow direction of the refrigerant. After the circulating water absorbs the heat stored in the ground, it also absorbs the heat of the heating water heated by solar energy and wind energy in tank 131. Part of the circulating water after absorbing heat exchanges heat with the refrigerant in the condenser 61, and the refrigerant evaporates and absorbs heat. The refrigerant after absorbing heat exchanges heat with the indoor water in the evaporator 62 and transfers the heat to the user to provide heating for the user; the other part of the circulating water after absorbing heat is supplied to the energy storage water tank 7, exchanges heat with the user's tap water, and supplies hot water; the circulating water that loses heat returns to the return water side of the heat exchange pipe 4, returns to the ground through the heat exchange pipe 4 to absorb heat, and continues the heat exchange cycle.
[0053] The above implementation plan proposes an intelligent heating system that comprehensively utilizes multiple clean energy sources, fully utilizes clean energy for heating, achieves rational resource utilization, and saves non-renewable resources; a heat exchange medium is placed in the intelligent heating system, which can automatically adjust according to changes in solar radiation conditions or wind conditions, absorb the heat generated in the heater or collector, and transfer the heat to the collector or heater, realizing centralized heating by connecting solar energy and wind energy in series, improving heating efficiency, and greatly reducing the disadvantages of using a single clean energy source that is greatly affected by weather and seasonal fluctuations.
[0054] The heating system introduces heat exchange pipes and sets up summer and winter heat exchange routes. In summer, the waste heat generated by solar energy and wind energy and the heat generated by user circulation are stored underground through circulating water that exchanges heat with groundwater. In winter, when solar energy and wind energy are insufficient for heating, the heat generated by the heated water and the heat stored underground are circulated to the heat pump unit and the energy storage tank through circulating water to supply users, thereby providing heat and water for users; the heating water and circulating water in the collector or heater switch their action routes according to seasonal regulation, and heat exchange with users is realized through the heat pump unit to meet the needs of heating or cooling; heat can be "stored in summer and used in winter"
