It is effective to wash its tube pass with some solution and its shell pass with acid.
原因：当室外湿度大的时候，室内机制热，室外机冷凝器表面会结霜，这样会影制热效率。
Reason: when the humidity outdoor, indoor, outdoor heating surface of the condenser will, this will be the frost of heating efficiency.
主要是由于冷凝器表面严重积灰堵塞，或者是受腐蚀影响而减弱了换热效果。
The main reason of which is the heat transfer efficiency is weakened by jamming heavily or corroding the surface of the condenser.
