Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heating device based on an air source heat pump. Background Technique

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source air to a high-level heat source, and it can be adapted to indoor air conditioners, floor heating pipelines, radiators, etc. to achieve heating of the indoor environment.

[0003] After retrieval, the patent with the publication number CN218033328U discloses an air energy hybrid radiator heating system for apartment houses, which combines an air source heat pump and a mini electric heating module. The hot water generated by the air source is further heated by the mini electric heating module, so as to meet the heat demand of the radiator.

[0004] Although the above scheme can use the mini electric heating module to heat the water in the pipeline to make up for the deficiency of the low water temperature of the air source heat pump in cold weather, the mini electric heating module needs to heat the heating water of the entire air source heat pump system. Therefore, when the outdoor temperature is too low and the air source heat pump cannot operate normally, this scheme cannot meet the indoor heating demand only by using the mini electric heating module, resulting in the radiator not being able to be used normally, and there is room for improvement.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0023] Please refer toFigures 1 to 4 In the embodiment of the present utility model, a heating device based on an air source heat pump includes radiators. The radiator includes a hanging bracket 18. On the front wall of the hanging bracket 18, a first heat exchange tube 1, several second heat exchange tubes 2, and a third heat exchange tube 3 are fixedly connected in sequence from bottom to top. The first heat exchange tube 1, several second heat exchange tubes 2, and a third heat exchange tube 3 are sequentially connected through a connecting pipe 4 to form a serpentine heat exchange pipeline. One end of the first heat exchange tube 1 is fixedly penetrated with a water inlet pipe 6, and one end of the third heat exchange tube 3 is fixedly penetrated with a water outlet pipe 7. Valves 8 are installed on both the water inlet pipe 6 and the water outlet pipe 7. The water inlet pipe 6 and the water outlet pipe 7 are jointly connected to a return pipe 9. A circulation pump 10 is installed on the return pipe 9. Electric control valves 11 are installed on the outer wall of the return pipe 9 near both ends. Electric heating mechanisms are installed on the first heat exchange tube 1, the second heat exchange tube 2, and the third heat exchange tube 3. An active heat exchange mechanism is installed on the first heat exchange tube 1.

[0024] By adopting the above scheme in the present utility model, after connecting the water inlet pipe 6 and the water outlet pipe 7 to the heating water pipeline of the air source heat pump, opening the two valves 8 and closing the two electric control valves 11 can make the heating water flow in the serpentine heat exchange pipeline composed of the first heat exchange tube 1, the second heat exchange tube 2, and the third heat exchange tube 3, so as to dissipate heat into the room and play a heating role.

[0025] When the water temperature of the air source heat pump is relatively low, starting the electric heating mechanisms on the first heat exchange tube 1, the second heat exchange tube 2, and the third heat exchange tube 3 to heat the water in each heat exchange tube can increase the water temperature in the heat exchange tube, thereby improving the heating effect.

[0026] When the air source heat pump cannot be used normally, closing the two valves 8 and opening the two electric control valves 11 can connect the serpentine heat exchange pipeline to the return pipe 9. Then starting the circulation pump 10 and the electric heating mechanism can heat the heating water in each heat exchange tube and make the heating water circulate between the serpentine heat exchange pipeline and the return pipe 9, so that the radiator can normally provide heating, and the use effect is good.

[0027] Specifically combined with Figure 1 and Figure 2 , the same ends of the first heat exchange tube 1, the second heat exchange tube 2, and the third heat exchange tube 3 are jointly fixedly sleeved with a housing 5. The water inlet pipe 6 and the water outlet pipe 7 both pass through the housing 5. The valve 8 is located outside the housing 5. The return pipe 9 is located inside the housing 5. The top outer wall of the water outlet pipe 7 near its water inlet end is fixedly communicated with a water injection pipe 16. The top end of the water injection pipe 16 penetrates through the housing 5 and is detachably and sealingly connected with a plug 17.

[0028] Through the setting of the housing 5, the water inlet pipe 6, the water outlet pipe 7, the return pipe 9, the circulation pump 10, the electric control valve 11, etc. can be shielded, thereby improving the aesthetics of this radiator. Through the setting of the water injection pipe 16, when the valve 8 is closed, the heating water can be injected into the radiator through the water injection pipe 16, so as to facilitate the use of the radiator when the radiator is not connected to the pipeline of an air source heat pump or other heating systems.

[0029] Specifically in combination with Figure 2 and Figure 3 In an embodiment of the present invention, the electric heating mechanism includes an electric heater 13, the electric heater 13 is hermetically penetrated through the corresponding first heat exchange tube 1, second heat exchange tube 2 and third heat exchange tube 3, and the electric heater 13 is located inside the housing 5, and a temperature sensor 12 is installed on the outer wall of the water inlet pipe 6 near its water outlet end.

[0030] Specifically in combination with Figure 3 and Figure 4 In an embodiment of the present invention, the first heat exchange tube 1, the second heat exchange tube 2 and the third heat exchange tube 3 are all in the shape of a square pipe, and the inner side of the first heat exchange tube 1 is an installation groove 19. The active heat exchange mechanism includes a wind wheel 21 located in the installation groove 19. Both ends of the wind wheel 21 are rotatably connected to partition plates 20, and both partition plates 20 are fixedly connected to the inner wall of the installation groove 19. A motor 22 is fixedly connected to the outer wall of one partition plate 20, and the output shaft of the motor 22 is fixedly connected to one end of the wind wheel 21. An upper cover plate 23 and a lower cover plate 25 are fixedly connected in the installation groove 19. The wind wheel 21 is located between the upper cover plate 23 and the lower cover plate 25. An air outlet 24 is provided through the top of the upper cover plate 23, and an air inlet 26 is provided through the bottom of the lower cover plate 25.

[0031] When this radiator is just started and the indoor temperature is relatively low, by starting the motor 22 to drive the wind wheel 21 to rotate, an air flow can be blown upward from the air outlet 24, and this air flow passes through the inner sides of the second heat exchange tube 2 and the third heat exchange tube 3, thereby improving the heat exchange efficiency of the second heat exchange tube 2 and the third heat exchange tube 3, so that the indoor temperature rises rapidly, and the use effect is good.

[0032] Specifically in combination with Figure 1 and Figure 2 In an embodiment of the present invention, a programmable controller 14 is fixedly installed in the housing 5, and a control panel 15 is fixedly penetrated and installed on the outer wall of the housing 5.
