This essay will remark on auto air-condition noise problems through studying expansion valve. The main reasons incurred noise are two, one is vibration, which is from big air bubble caused by the refrigerant flows through expansion valve. Another is resonance, which is from engineering working itself. So, the two methods for eliminating noise are found. On one hand, through increasing damp to weaken resonance. On another hand, through taking off air bubble to eliminate vibration. The essay presents method of solving noise through improving expansion valve and elaborate the disadvantages caused by these solvement.
