Liquid desiccant air conditioning systems have become popular because of the advantage in removal of latent heat load. Regeneration performance is experimentally studied on a liquid regenerator filled with novel Z-type packing (specific surface area 160 m2·m-3) and corrugated structured packing (specific surface area 450 m2·m-3).The results show that

under the same operating condition in winter

the regeneration rate

the regeneration efficiency and the regeneration thermal efficiency of Z-type packing are about 40%

50% and 70% of the corrugated structured packing respectively. In addition

all the regeneration performance indicators have large space to improve through reducing the space between Z-type units. The Z-type packing in liquid desiccant regenerator is promising compared with the corrugated structured packing.
