Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a nested multi-stage air conditioner silencer. Background Art

[0002] When the air source variable frequency cooling and heating machine is running, the compressor frequency will continue to change according to the ambient temperature, water temperature and other conditions. At this time, as the compressor frequency continues to increase, the noise and vibration of the unit will become more and more obvious. The loud noise will affect the user's sleep quality at night, thus bringing a bad sensory experience, and the vibration of the unit will cause fatigue in the pipeline. Over time, when the fatigue limit is reached, the pipeline will break, and the refrigerant will flow out of the unit and cannot be used normally. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a nested multi-stage air conditioner silencer, which has a simple structure, prolongs the service life, reduces noise pollution and improves the use comfort.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A nested multi-stage air conditioner silencer comprises a shell and a pipe, wherein the pipe is mounted on the shell, the bottom end of the pipe extends into the shell and has primary jet holes distributed along the circumference, a jet ring is also fixed to the bottom end of the pipe, the pipe is located in the shell and has more than one reflector fixed in the vertical direction, and the reflector has secondary jet holes distributed along the circumference.

[0006] A further technical solution is that three groups of primary jet holes and reflective plates are provided on the pipe in the vertical direction along the circumference, and the three groups of primary jet holes and reflective plates are staggered with each other in the vertical direction on the pipe. Of course, it can also be one group of primary jet holes and reflective plates.

[0007] A further technical solution is that a sleeve is fixed in the middle of the reflective plate, and an upward folded flange is distributed on the outermost circumference of the reflective plate to guide the refrigerant to be discharged from the secondary jet holes on the reflective plate. The sleeve can be welded and fixed to the connecting pipe, so that the reflective plate is more firmly attached to the connecting pipe.

[0008] The beneficial effects of the utility model are:

[0009] The high-temperature and high-pressure refrigerant discharged from the compressor flows through the connecting pipe. When it flows out from the first-level jet hole on the connecting pipe, the fluid pressure drops rapidly and the flow rate decreases. When it flows through the cavity, the fluids in the cavity collide with each other, and the fluid kinetic energy cancels each other out. After multiple collisions, the kinetic energy of the fluid itself is finally dissipated from the shell to the outside in the form of internal energy. Therefore, the vibration amplitude of the overall pipeline is greatly reduced, and the phenomenon of cracks and tears at the welding and bending parts of the pipeline under large-amplitude vibration is avoided; at the same time, the impact of high-temperature and high-pressure refrigerant on the pipeline will also be reduced, and the life of the pipeline will be increased; because the refrigerant has passed through multiple jets and reflective plates, the flow rate is reduced, the flow state is more stable, and the turbulent sound of the gas flow is also reduced, thereby bringing a comfortable experience to users.
