DETAILED DESCRIPTION

[0024] 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 them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention is a solar heating and air-conditioning system, which includes a hot water circulation device, a heating device and an air-conditioning device.

[0026] The hot water circulation device includes an energy storage water tank 1, a heat collector 2 and an insulation water tank 3. The lower end of the energy storage water tank 1 is connected to one end of the heat collector 2 through a circulation pipeline 1 4, and the other end of the heat collector 2 is connected to the upper end of the energy storage water tank 1 through a circulation pipeline 2 5. The circulation pipeline 1 4 is provided with a water pump 6, and the circulation pipeline 1 4 is connected to a tap water pipeline 1 7. The tap water pipeline 1 7 is provided with a valve 1 8. The upper end of the energy storage water tank 1 is connected to the lower end of the insulation water tank 3 through a water supply pipeline 9, and the upper end of the insulation water tank 3 is connected to a water supply pipeline 10. The water supply pipeline 9 is provided with a booster pump 1 11 and a valve 2 12. The water supply pipeline 9 is connected to a tap water pipeline 2 13, and a valve 3 14 is provided on the tap water pipeline 2 13. The heating device includes a heating pipe 15, several tributary cold and hot water circulation pipes 17, a heating pipe 2 36 and a fan heat exchanger 16. One end of the heating pipe 15 is connected to the water supply pipe 9, and the other end is connected to one end of the heating pipe 2 36 through several tributary cold and hot water circulation pipes 17. The other end of the heating pipe 2 36 is connected to the lower end of the energy storage water tank 1. A fan heat exchanger 16 is provided on one side of the several tributary cold and hot water circulation pipes 17, and a booster pump 2 25 is provided on the heating pipe 2 36. The air conditioning device includes a first heat transfer pipeline 18, a heat pump 19 and a heat exchanger 33. A cold end pipeline 20 and a hot end pipeline 21 are respectively provided on both sides of the heat pump 19. The cold end pipeline 20 exchanges heat with the first heat transfer pipeline 18 through the heat exchanger 33. A radiator 22 is provided on one side of the hot end pipeline 21 for discharging excess heat. The two ends of the first heat transfer pipeline 18 are respectively connected to the energy storage water tank 1, and the middle of the first heat transfer pipeline 18 is connected to the heat exchanger 33. A circulating pump 23 is also provided on the first heat transfer pipeline 18.

[0027] In order to enable the solar heating and air-conditioning system to provide hot water in summer, the insulated water tank 3 is also connected to a second heat transfer pipeline 27. The second heat transfer pipeline 27 exchanges heat with the hot end pipeline 21 through the heat exchanger 2 34 on the hot end pipeline 21. The second heat transfer pipeline 27 is provided with a circulation pump 28. The tap water in the insulated water tank 3 is circulated through the second heat transfer pipeline 27 and the circulation pump 2 28, and heat is exchanged with the hot end pipeline 21 through the heat exchanger 2 34 to increase the temperature of the tap water in the insulated water tank 3.

[0028] When the solar heating and air conditioning system is used in spring and autumn, Figure 2 As shown, the tap water in the energy storage tank 1 is transported from the energy storage tank 1 to the heat collector 2 via the circulation pipe 1 4 through the water pump 6, and circulated back to the energy storage tank 1 from the heat collector 2 via the circulation pipe 2 5. When the tap water passes through the heat collector 2, the heat collector 2 transfers heat to the tap water under the sunlight, so that the tap water is heated; at the same time, the heated tap water in the energy storage tank 1 is transported from the energy storage tank 1 to the insulation water tank 3 via the booster pump 1 11 and the valve 2 12 through the water delivery pipe 9. The insulation water tank 3 is connected to the water pipe 10. Hot water can be used by opening the water pipe 10. While using hot water, the tap water pipe 1 7 replenishes tap water into the energy storage tank 1 through the valve 1 8.

[0029] When the solar heating and air conditioning system is used in winter, Figure 3 As shown, in addition to the operation of the water circulation device, the heating device is also operating at the same time. The tap water with temperature in the water supply pipe 9 passes through the heating pipe 1 15 and is then divided into several branch cold and hot water circulation pipes 17. Finally, it is circulated back to the energy storage water tank 1 through the heating pipe 2 36. When the tap water with temperature passes through the several branch cold and hot water circulation pipes 17, the heat of the tap water is transferred to the air, and the high-temperature air is blown into the room through the fan heat exchanger 16.

[0030] When the solar heating and air conditioning system is used in summer, Figure 4As shown, since the hot water consumption is small in summer, the water pump 6 can be turned off and the collector 2 stops working at the same time; at this time, the air conditioning device starts to work, and the heat pump 19 of the air conditioning device is respectively provided with a cold end pipeline 20 and a hot end pipeline 21. The tap water in the energy storage water tank 1 circulates between the energy storage water tank 1 and the heat exchanger 1 33 through the circulation pump 1 23 and the first heat transfer pipeline 18. Since the cold end pipeline 20 is connected to the heat exchanger 1 33, when the tap water circulates to the heat exchanger 1 33, it is affected by the cold end pipeline 20 and cooled; at the same time, the cooled tap water in the energy storage water tank 1 passes through the booster pump 2 25 in sequence through the heating pipeline 2 36, several tributaries of the cold and hot water circulation pipelines 17, the heating pipeline 15, and the water delivery pipeline 9 by the energy storage water tank 1. The lower end of the tank 1 circulates back to the upper end of the energy storage water tank 1. When the cooled tap water passes through several tributaries of the hot and cold water circulation pipes 17, the cold energy of the low-temperature tap water is transferred to the air, and the low-temperature air is blown into the room through the fan heat exchanger 16; at the same time, the tap water in the insulated water tank 3 is circulated outside the insulated water tank 3 through the second heat transfer pipe 27 via the circulating pump 28. Since the second heat transfer pipe 27 exchanges heat with the hot end pipe 21 through the heat exchanger 2 34, when the tap water circulates to the heat exchanger 2 34, it is affected by the hot end pipe 21 and the temperature is increased. The water pipe 10 can be opened to use hot water. While using hot water, the tap water pipe 2 13 replenishes tap water into the insulated water tank 3 through the valve 3 14.

[0031] To further utilize solar energy to conserve electricity, the solar heating and air conditioning system also features a power supply device, comprising a solar panel 29, a battery 30, and an AC / DC converter 31. The solar panel 29 is removably mounted on the collector 2 and connected to the battery 30, which in turn powers the heat pump 19 via the AC / DC converter 31. The power supply device also includes a charging station 32, which is connected to the battery 30 and can be used to charge other devices. The AC / DC converter 31 is also connected to a utility line 35 to supplement household electricity consumption.

[0032] It should be noted that in this solar heating and air-conditioning system, the solar energy utilization rate of the solar power generation panel 29 is 15%-20%, and the solar energy utilization rate of the collector 2 is greater than 60%. In spring, autumn and summer, since there is no need to supply heating, the power supply device solar power generation panel 29 can partially block the collector 2 for power supply; in winter, due to the demand for heating and hot water, the solar power generation panel 29 should be removed to avoid the solar power generation panel 29 blocking the collector 2, thereby ensuring that the solar energy utilization rate of the collector 2 reaches the highest.

[0033] To allow the tap water in the heat collector 2 to flow back into the energy storage tank 1 through circulation line 1 4 and circulation line 2 5 when the hot water circulation system is deactivated, a one-way valve 24 is also installed on circulation line 2 5. When the hot water circulation system is deactivated, air can enter circulation line 2 5 through one-way valve 24, allowing the tap water in the heat collector 2 to flow back into the energy storage tank 1 through circulation line 1 4 and circulation line 2 5. Furthermore, valves 4 26 are each installed on each of the several branch cold and hot water circulation lines 17. When cooling or heating is not required, valves 4 26 can be closed. If branch cold and hot water circulation lines 17 are located in different rooms, valves 4 26 can also be used to control them individually.

[0034] The water tank, heat collector, water pump, valve, booster pump, fan heat exchanger, heat pump, radiator, circulation pump, one-way valve, solar panel, battery, AC / DC converter, charging pile, and heat exchanger mentioned in the present invention are all existing technologies and can be purchased commercially.
