Abstract
Compression type refrigerator has been used as automotive air conditioner, so we need additional fuel for air conditioning. Absorption chiller is heat driven type refrigerator, so when we adapt it for automotive air conditioner and use with waste heat, it will reduce the fuel consumption. We are developing the absorption chiller for automobile which have the tolerance for unique environment of automobile. In this work, we propose new type absorber which has heat exchanger smeared lithium-bromide(LiBr) solution by rotors with brushes. And now, wet area of heat exchanger is important factor for the performance. In this paper, the method to visualize the liquid film flow of solution is established by using laser and fluorescent agent, and wet area of surface of heat exchanger is quantified.
