DESIGN OF THE EVAPORATOR OF THE COMPACT NON-PUMPED LITHIUM-BROMIDE ABSORPTION AIR CONDITIONER
By Wu Junmei; Zhang Zhiyou and Zhang Bingdu
An evaporator design scheme for the compact non-pumped lithium-bromide absorption air conditioner was raised based on the evaporating characteristics of water under vacuum conditions. The theoretical analysis of heat exchange mechanism in the evaporator tubes was conducted and four kinds of horizontal evaporator tubes were tested with the single tube analogue method,The empirical formula of evaporating heat transfer coefficient was obtained. The tube of 12mm in inside diameter with its low part of the outlet section being blinded to the height of quarter di is of highest heat transfer efficience.
