[0002] 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. It works based on the reverse Carnot cycle principle, absorbing low-grade heat from the ambient air and converting it into high-grade heat to heat water or air, achieving indoor heating or providing hot water.

[0003] The air source heat pump itself is mainly composed of an evaporator, a compressor, a condenser and an expansion valve. The main source of noise in the air source heat pump is the compressor. There are many factors that cause noise when the compressor is running. For example, when the compressor is frequently in a high-frequency state, it will produce a lot of noise. In addition, the compressor is rigidly installed directly on the roof with other components, so the vibration of the compressor during operation will resonate with the wall building, thereby increasing the noise. This is a situation that cannot be eliminated by adding sound insulation cotton or sound insulation coating. For this reason, we provide an air source heat pump with noise reduction function.

The independent outer box is to place the condenser and the compressor in the air source heat pump directly and separately in an independent box. The buffer box is filled with salt water and occupies more than half of the space in the buffer box. The horizontal float and the longitudinal float can provide buoyancy for the compressor.

In addition, the horizontal float and the longitudinal float can also be used to lift the compressor. The buoyancy brought to the float can reduce the power output of electromagnet 1 and electromagnet 2, and maintain the buoyancy of the compressor with a lower power consumption. Since the liquid can conduct waves, when the vibration of the compressor is transmitted to the water, it will be transmitted to all sides of the water. The energy will gradually decay and be lost during the transmission process. In addition, the buoyancy and magnetic suspension provide support for the compressor, thereby cutting off the direct rigid connection between the compressor and other components, and thus effectively reducing the resonance of the entire equipment and the wall, which has a good buffering effect, thereby solving the problem of high noise generated by the compressor during daily operation.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Example: Figure 1-Figure 9As shown, the present invention provides a technical solution of an air source heat pump with a noise reduction function, including an independent outer box 1, a buffer box 2 is arranged inside the independent outer box 1, two compressors 3 are arranged inside the buffer box 2, a horizontal float 4 and a vertical float 5 are arranged outside the compressor 3, and an electromagnet 1 6 and an electromagnet 2 7 are arranged below the compressor 3. The independent outer box 1 is to place the condenser and the compressor 3 in the air source heat pump directly and separately in an independent chassis, the buffer box 2 is filled with salt water and occupies more than half of the space in the buffer box 2, the horizontal float 4 and the vertical float 5 can provide buoyancy for the compressor 3, and the electromagnet 1 6 and the electromagnet 2 7 have the same polarity, and the principle of like charges repel each other is used to repel the electromagnet 1 6 and the electromagnet 2 7. The magnet 2 7 is energized, so that the electromagnet 1 6 and the electromagnet 2 7 hold up the compressor 3. Together with the buoyancy brought by the horizontal float 4 and the longitudinal float 5, the power output of the electromagnet 1 6 and the electromagnet 2 7 can be reduced, and the buoyancy of the compressor 3 can be maintained at a lower power consumption. Since the liquid has the ability to conduct waves, when the vibration of the compressor 3 is transmitted to the water, it will be transmitted on all sides by the water. The energy will gradually decay and be lost during the transmission process. In addition, the compressor 3 is supported by buoyancy and magnetic suspension, thereby cutting off the direct rigid connection between the compressor 3 and other components, thereby effectively reducing the resonance phenomenon of the entire equipment and the wall, and having a good buffering effect, thereby solving the problem of the compressor 3 generating a lot of noise during daily operation.

[0033] The inner surface of the independent outer box 1 and the outer surface of the buffer box 2 are covered with a layer of sound insulation cotton. Since the liquid in the buffer box 2 acts as a medium to buffer part of the vibration, and the air will also transmit the noise caused by the vibration, the sound insulation cotton inside the independent outer box 1 and outside the buffer box 2 can further block the noise transmitted in the air.

[0034] A protective layer 10 is fixedly installed on the outer surface of the floating plate 8, and a fixing frame 11 is fixedly installed on the inner wall of the protective layer 10. The inner wall of the fixing frame 11 is fixedly installed with the outer surface of the compressor 3. The protective layer 10 and the floating plate 8 can reduce the external liquid from entering the interior of the compressor 3, and the fixing frame 11 can provide support for the compressor 3 to reduce the phenomenon of the compressor 3 falling off.

[0035] The compressor 3 is equipped with a floating plate 8, the electromagnet 1 6 is fixedly installed on the bottom surface of the floating plate 8, the electromagnet 2 7 is fixedly installed on the inner bottom surface of the buffer box 2, and the outside of the electromagnet 1 6 and the electromagnet 2 7 are both provided with an isolation shell 9, the isolation shell 9 can provide protection for the electromagnet 1 6 and the electromagnet 2 7, and the isolation shell 9 itself is made of plastic, and has good water-proof and insulating properties, so as to prevent the electromagnet 1 6 and the electromagnet 2 7 from directly contacting the liquid to produce a short circuit, and the floating plate 8 can provide support for the compressor 3 and provide a certain buoyancy.

[0036] The floating plate 8, the protective layer 10 and the buffer box 2 are all provided with an interlayer 12, and the interlayer 12 is filled with a high magnetic permeability iron-nickel alloy, which can effectively gather the magnetic field, guide the external magnetic field into the interior of the material and redistribute it, thereby reducing the magnetic field strength in the external area of ​​the material, achieving a relative isolation effect, and reducing the influence of electromagnet 1 6 and electromagnet 2 7 on the compressor 3.

[0037] A regulating box 13 and a water pump 14 are installed inside the independent outer box 1. An inlet pipe 15 is fixedly installed at the input end of the water pump 14. The outer surface of the inlet pipe 15 is fixedly installed on the inner side of the regulating box 13. The number of the inlet pipes 15 is two, and the other inlet pipe 15 connects the inside of the regulating box 13 with the inside of the buffer box 2. A water outlet pipe 20 is fixedly installed on the inner side of the regulating box 13. The other end of the water outlet pipe 20 is fixedly installed on the inner side of the buffer box 2. The water outlet pipe 20 is connected to the output end of the water pump 14. The number of the water outlet pipes 20 is two, and the other water outlet pipe 20 connects the output end of the water pump 14 with the inside of the buffer box 2. They are interconnected, and the water pump 14 can pump the water in the regulating box 13 into the buffer box 2 through the water outlet pipe 20. The buffer box 2 is provided with a closing door, which can make the interior of the buffer box 2 form a sealed state when closed, and the closing door can only be opened outward. Therefore, when the water pump 14 is turned on, a high pressure will be formed inside the buffer box 2, and a negative pressure will be formed inside the regulating box 13. Under the action of the two, the water in the buffer box 2 can flow continuously into the regulating box 13 through the water inlet pipe 15, and the salt content in the liquid can be adjusted by adding water or salt to the regulating box 13, thereby controlling the size of the buoyancy.

[0038] The independent outer box 1 is connected to the flow box door 16 by a hinge, and the independent outer box 1 and the flow box door 16 cooperate with each other to form an independent space. The water inlet pipe 15 between the buffer box 2 and the regulating box 13 directly passes through the space formed between the independent outer box 1 and the flow box door 16, and a water valve 17 is installed in the space. The water valve 17 can open or close the flow of the water inlet pipe 15, and a one-way valve is installed afterwards to prevent backflow.

[0039] The inner top surface and the inner bottom surface of the independent outer box 1 are both provided with a slide 18, and the outer surface of the independent outer box 1 is slidably connected to a folding door 19.

The outer surfaces of the water outlet pipe 20 and the water inlet pipe 15 both pass through the inner side of the independent outer box 1. The independent outer box 1 and the folding door 19 form another larger independent space, and the water pump 14 and the control box 13 are both arranged in the space and move in a fixed direction given by the slide 18. The slide 18 can give a fixed moving direction for the folding door 19. The above-mentioned independent space can reduce the number of times the independent outer box 1 is opened during daily maintenance, so as to reduce the loosening of the internal sound insulation cotton, thereby maintaining the sound insulation performance.

[0040] A transverse auxiliary plate 21 and a longitudinal auxiliary plate 22 are fixedly installed on the inner wall of the buffer box 2, a longitudinal floating frame 23 is fixedly installed on the bottom surface of the floating plate 8, a transverse floating frame 24 is fixedly installed on the protective layer 10, the transverse floating cylinder 4 is rotatably connected to the inside of the transverse floating frame 24, and the longitudinal floating cylinder 5 is rotatably connected to the inside of the longitudinal floating frame 23. The transverse auxiliary plate 21, the longitudinal auxiliary plate 22, the transverse floating cylinder 4 and the longitudinal floating cylinder 5 can provide buoyancy for the protective layer 10 and the floating plate 8 around to reduce the overall rollover phenomenon, and the transverse auxiliary plate 21 and the longitudinal auxiliary plate 22 can guide the protective layer 10 and the floating plate 8 to always be close to the center area and move downward through the transverse floating cylinder 4 and the longitudinal floating cylinder 5 when the water level drops.

A trapezoidal receiving frame 28 is provided below the trapezoidal positioning block 27 and is fixedly installed on the inner bottom surface of the buffer box 2. The plastic spring 26 has a small positioning effect, reducing the signs of tilting of the floating plate 8. When the water level drops, the floating plate 8 can drive the trapezoidal positioning block 27 to move downward. The trapezoidal positioning block 27 is made of rubber as a whole and will be directly seated on the trapezoidal receiving frame 28 to play a direct rigid load-bearing role.

[0042] The input and output ends of the compressor 3 are fixedly installed with a telescopic hose 29, and the top end of the telescopic hose 29 is fixedly installed on the inner top wall of the buffer box 2. When the water level changes, the compressor 3 moves downward to stretch the telescopic hose 29, allowing it to operate normally.
