Air conditioner compressor suction pipe assembly installation structure

Abstract

The invention discloses an air conditioner compressor air suction pipe assembly mounting structure, and belongs to the technical field of air conditioning. An air suction pipe assembly in the specific direction is adopted, the vibration condition of air conditioner compressor air suction pipe and the low-frequency noise condition of equipment can be reduced, and basically no additional cost is increased. The structure comprises a compressor body, an air suction pipe and a four-way valve. The air suction pipe sequentially comprises a first vertical straight pipe section, a first oblique straight pipe section, a second oblique straight pipe section, a second vertical straight pipe section, a first horizontal straight pipe section, a second horizontal straight pipe section, a third horizontal straight pipe section and a third vertical straight pipe section from the outlet end to the inlet end. The air suction pipe with the specific structure, shape and direction is adopted, the air suction pipe is mounted according to a certain position relation, and the problem that a compressor pipeline system is poor in vibration can be effectively solved. Meanwhile, it is not needed to add additional balance weights or damping blocks to a pipeline for damping, and therefore increase of the production cost can be effectively avoided.

Problems solved by technology

[0002] In the inverter air conditioner compressor pipeline system (compressor pipeline system generally includes compressor body, suction pipe assembly, exhaust pipe assembly, four-way valve and other components), since the single-cylinder rotary compressor will The unbalanced force will cause the vibration of the compressor piping system, in which the suction pipe close to the compressor liquid reservoir will vibrate more, and the stronger the cooling and heating capacity of the air conditioning system, the greater the power of the compressor, and the compressor body will The greater the vibration and the unbalanced force generated during operation, especially in the piping system of the single-cylinder rotor compressor of the 3-hp inverter air conditioner, the vibration of the suction pipe is often difficult to solve; The natural frequency of the frequency band is relatively dense. Although the compressor has torque compensation control in the low frequency band, if the pipeline design is unreasonable, it is easy to cause resonance in the range of low frequency operation of the compressor (below 40Hz), and the vibration in the compressor pipeline system Most of the problems focus on the vibration of the compressor when it is running at low frequency; for most inverter air conditioners, the initial frequency is generally around 30Hz, but sometimes due to factors such as high temperature conditions and reliability of electronic control, it is necessary to turn the inverter air conditioner compressor The initial frequency is set below 30Hz, especially for the 3-horsepower inverter air conditioner single-cylinder rotary compressor, the vibration of the suction pipe in the low frequency range is difficult to solve

[0003] At present, the common method to solve the vibration of the air conditioner compressor suction pipe assembly is to change the natural frequency of the compressor piping system through the mass distribution method to reduce the vibration of the pipeline, that is, to add multiple counterweights and damping blocks to the pipeline. way to suppress pipeline vibration, but the above method will inevitably lead to an increase in production costs
