Description

Technical Field

[0001] The present invention belongs to the technical field of heat pump units, and in particular relates to an air source heat pump unit system capable of efficient heat exchange and noise reduction. Background Art

[0002] An air source heat pump is a heat pump system that uses outdoor air as a low-temperature heat source. It is mainly used for heating and hot water, and absorbs, transmits and releases heat through a compression cycle.

[0003] In the prior art, air source heat pumps generate noise during operation, which can reach 80dB within a one-meter range. For a unit system composed of multiple air source heat pumps, the noise is even louder, causing noise pollution, which places high demands on the location of its installation. In addition, during operation, air source heat pumps absorb heat from the air, and the temperature of the released air decreases, so a cold island effect will appear around them, which will affect the heat exchange effect and thus the heating effect. Summary of the invention

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please also read Figure 1 and Figure 2, the air source heat pump 40 unit system capable of efficient heat exchange and noise reduction provided by the present invention is now described. The air source heat pump 40 unit system capable of efficient heat exchange and noise reduction includes an installation platform 10, an exhaust duct 20, a sound barrier wall 30, an air source heat pump 40 and a fan 50. A placement plane is provided at the top of the installation platform 10. An air passage 12 connected to the atmosphere is provided in the installation platform 10. The exhaust duct 20 is fixedly mounted on the placement plane and has a cylinder cavity with an open top. The bottom end of the exhaust duct 20 is connected to the air passage 12; the opening of the exhaust duct 20 is detachably connected to the sealing cylinder cover 22; the sound barrier wall 30 is fixedly mounted on the placement plane and is arranged around the exhaust duct 20, and an annular isolation cavity 11 is formed between the sound barrier wall 30 and the exhaust duct 20. There are multiple air source heat pumps 40, each of which is arranged in an annular isolation chamber 11 around the axis of the exhaust cylinder 20 and has an air outlet connected to the cylinder cavity and an air inlet. The fan 50 is arranged in the cylinder cavity, and is used to transport the gas led into the cylinder cavity from each air outlet to the air outlet channel 12 to be discharged from the annular isolation chamber 11.

[0034] Compared with the prior art, the air source heat pump 40 unit system provided in this embodiment is capable of efficient heat exchange and noise reduction. The annular isolation chamber 11 formed by the sound barrier wall 30 and the exhaust duct 20 on the installation platform 10 can ensure the installation of each air source heat pump, and at the same time, the noise generated by the air source heat pump 40 can be isolated, thereby avoiding noise pollution. The exhaust duct 20 is connected to the air outlet of each air source heat pump 40, and an air outlet channel 12 is provided on the installation platform 10, and a fan 50 is provided, which can ensure that the air passing through each air source heat pump 40 enters at the top of the exhaust duct 20 and flows out at each air outlet channel 12. This can ensure the promotion of the airflow, so that the cold airflow flows out to the outside of the annular isolation chamber 11, avoiding the cold island effect, thereby ensuring the heat exchange effect and the heating effect.

[0035] In some embodiments, the air source heat pump 40 and the exhaust duct 20 can be used as follows: Figure 1 See the structure shown. Figure 1 Each air outlet is connected to the exhaust cylinder 20 via a connecting pipe 41.

[0036] The setting of the connecting pipe 41 can ensure that the exhaust duct 20 is connected to each air source heat pump 40, thereby ensuring that the air flowing through each air source heat pump 40 is discharged from the exhaust duct 20. At the same time, the connecting pipe 41 can also ensure compensation for the position of each air source heat pump 40, making the air source heat pump 40 more dispersed.

[0037] In this embodiment, the connecting pipe 41 can be a flexible heat-insulated pipe. In addition, the air outlet can be located at the top of each air source energy heat pump for easy connection.

[0038] In some embodiments, the sound barrier wall 30 may be formed as follows: Figure 1 See the structure shown. Figure 1 The top of the sound barrier wall 30 is provided with a bending portion 31 that bends inward. The setting of the bending portion 31 can ensure the interception of sound waves, and then ensure that the sound waves continue to reflect obliquely downward, further effectively reducing noise pollution.

[0039] In some embodiments, see Figure 1 The air source heat pump 40 unit system capable of efficient heat exchange and noise reduction also includes a first noise power generation module 32 and a matching controller. A plurality of first noise power generation modules 32 are provided, each of which is arranged at intervals around the inner wall of the sound barrier wall 30, and can generate electricity through the noise generated by each air source heat pump 40.

[0040] The work of the fan 50 requires electric energy, and the continuous work of the fan 50 will inevitably require a large amount of electric energy, so a plurality of first power generation modules are provided, and the plurality of first power generation modules are arranged in annular intervals on the inner wall of the sound barrier wall 30, which can ensure that each first power generation module works independently, thereby ensuring the power generation effect. The controller can be electrically connected to the fan 50 and each first power generation module to ensure that power is delivered to the fan 50.

[0041] In this embodiment, each first noise power generation module 32 may include a plurality of parallel power generation components, a filter module electrically connected to the power generation components, a voltage stabilizing module, a power protection module and a battery. Each power generation component may include a receiver, a Helmholtz resonance cavity, a vibration membrane, a permanent magnet and a power generation coil. The receiver, the Helmholtz resonance cavity, the power generation coil and the permanent magnet are arranged in sequence. The receiver needs to be arranged with the opening facing the central axis of the exhaust duct 20 to collect noise, and the other parts can be arranged in a closed shell. The receiver is conical in shape and has a small opening at the end, and the end is connected to the Helmholtz resonance cavity. The Helmholtz resonance cavity may include a connected neck and a cavity, and the opposite ends of the Helmholtz resonance cavity are opened in the neck and the cavity respectively. The opening of the neck of the Helmholtz resonance cavity is connected to the end of the receiver, and the vibration membrane is fixed at the other end opening in the cavity of the Helmholtz resonance cavity. The generating coil is connected to the vibration membrane. When the sound is collected by the receiver and transmitted to the Helmholtz resonance cavity, it resonates with the air in the cavity of the Helmholtz resonance cavity. The vibration of the air drives the vibration of the vibration membrane, thereby driving the generating coil connected to the vibration membrane to move along the axis. The generating coil is sleeved on the permanent magnet, specifically, on one of the magnetic poles of the permanent magnet. The permanent magnet adopts a horseshoe magnet. A magnetic field is generated between its two magnetic poles, and the magnetic field intersects with the movement direction of the generating coil. When the generating coil moves driven by the vibration membrane, it will cut the magnetic flux lines in the magnetic field generated by the permanent magnet to generate an alternating electromotive force. Regarding the permanent magnet using a three-terminal horseshoe magnet, the generating coil is sleeved on a middle magnetic pole of the permanent magnet. A magnetic field is generated between the magnetic pole and the magnetic poles on both sides, and the two magnetic fields intersect with the movement direction of the generating coil respectively. When the generating coil moves driven by the vibration membrane, it will cut the magnetic flux lines in two magnetic fields at the same time and generate an alternating electromotive force, and the power generation efficiency is higher. The alternating potential is output through the output end of each power generation component and transmitted to the filter module to be converted into direct current, and then transmitted to the battery through the power protection module to store the electricity. This technology is existing technology and will not be described in detail here.

[0042] In some embodiments, see Figure 1 The air source heat pump 40 unit system that can efficiently exchange heat and reduce noise also includes a second noise power generation module 21, which is provided with multiple second noise power generation modules 21. Each second noise power generation module 21 is arranged at intervals around the outer wall of the exhaust duct 20, and can generate electricity through the noise generated by each air source heat pump 40.

[0043] Each second noise power generation module 21 can ensure that the noise is eliminated and utilized at the inner wall of the annular isolation chamber 11, and cooperate with the first noise power generation module 32 to cover the noise area, thereby ensuring the noise elimination effect and the power generation effect.

[0044] Each second noise power generation module 21 may have the same structure as each first noise power generation module 32 .

[0045] The air outlet can be located at the top of each air source heat pump, and the connecting port arranged on the exhaust duct 20 can be located above the air source heat pump 40. This can ensure the installation of the second noise power generation module 21 at the position below the connecting port, and make the second noise power generation module 21 face each air source heat pump 40, thereby effectively ensuring the noise processing and power generation effect.

[0046] In some embodiments, see Figure 2 The air source heat pump 40 unit system capable of efficient heat exchange and noise reduction also includes a photovoltaic panel 33, which is laid on the outer wall of the sound barrier wall 30. The air source heat pump 40 is located outdoors, so in order to further increase the generation of electricity, a photovoltaic panel 33 is set, which can collect solar energy during the day to further ensure the generation of power.

[0047] In some embodiments, the exhaust duct 20 and the sound barrier wall 30 can be formed as follows: Figure 3 See the structure shown. Figure 3 The height of the top of the exhaust tube 20 is higher than the height of the top of the sound barrier wall 30. This structure can ensure the volume of the cylinder cavity, thereby ensuring that more air volume is accommodated and the exhaust effect is guaranteed.

[0048] In some embodiments, the exhaust duct 20 and the sound barrier wall 30 can be formed as follows: Figure 3 See the structure shown. Figure 3 The sealing cylinder cover 22 is connected to the exhaust cylinder 20 by bolts. The sealing cylinder cover 22 and the exhaust cylinder 20 enclose a sealed cavity, which can ensure the protection of the fan and facilitate disassembly and assembly, thereby facilitating the maintenance of the fan 50 in the cylinder cavity.

[0049] In some embodiments, the air passage 12 may be formed as follows: Figure 3 See the structure shown. Figure 3 The air passage 12 includes a vertical section 121 and a horizontal section 122. The top of the vertical section 121 is connected to the bottom of the cylinder cavity. One end of the horizontal section 122 is connected to the bottom of the vertical section 121, and the other end extends to the outside of the installation platform 10.

[0050] The provision of the horizontal section 122 can ensure that air flows out of the annular isolation cavity 11, thereby promoting the airflow and avoiding the cold island effect.

[0051] It should be noted that in order to prevent the cold air flowing out of the air passage 12 from flowing back, a pipeline can be set at the pipe opening of the horizontal section 122 to transport the cold air to a longer distance.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
