Lnewqban, thanks for your reply.
In another word, is my understanding correct that only when there's an increase in moisture content (at/almost near dew point temperature) inside the airduct that condensation will happen, regardless of straight/bended airduct?
In a normal aircond system using flexible airduct, assume airflow with temperature & humidity conditions (Tdry=23°C; Tdew=13.4°C; RH=55% ) go through a bended flexible airduct where air turbulence is formed:
1. Can condensation happens at the bended flexible airduct due to air turbulence?
2...
