Comparing with conventional air handling process, the liquid desiccant air-conditioning system can dehumidify air without cooling down to its dew point. Meanwhile, counteraction cooling and heating can be avoided, which usually happened in conventional air handling process and led to huge energy waste. In addition, during the air handling process no condensation water separates out of the air in the liquid desiccant air-conditioning system, thus, avoid fungi thrives in moist environment of traditional air handling process. Not only being applied in dehumidification process in summer, the system can also realize humidification process in winter conditions efficiently.

This study experimentally examined the heat transfer characteristics of 180-deg turning duct under forced convection cooling, as the internal cooling structure of 180-deg turning duct is widely applied to industrial cooling. While several perforated holes were separately arranged within the 180-deg turning duct, the cold flow of better cooling capability was guided in the first duct into the second duct in advance, so as to reduce the overheating of the second duct and realize uniform cooling of the machine members. In addition, the centrally separated holes could yield extra turbulence against the air current, and the interaction between bypass air current and mainstream may possibly improve the overall heat transfer capability.
