查询词典 refrigerant

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.

本文从膨胀阀的角度去考虑解决汽车空调异响问题，认为产生异响的主要原因是制冷剂流经膨胀阀节流部时有大气泡存在引起振动与汽车发动机共振造成，从增加阻尼块来减振和分解大气泡来消除震动等两方面提出解决方法，并对此方法造成的不利方面也进行了阐述。

The one key to resolve the heat-transfer effect lies in making the refrigerant circulating rapidly and completely, the other one lies in decreasing the thermoresistance of evaporating section.

解决该散热装置的关键之一在于使载热介质迅速完全地循环，关键之二在于减小蒸发段的传热热阻。

The experiment results show that chocking occurs when downstream pressure decreases below the saturation pressure corresponding to upstream temperature and the mass flow rate of refrigerant becomes almost independent of downstream pressure.

试验结果表明，当节流短管的下游压力小于上游温度所对应的饱和压力时，制冷剂出现壅塞现象，此时制冷剂流量不再受下游压力变化的影响；上游压力、上游过冷度、短管直径对制冷剂流量的影响较大。
