Abstract

In this study, an experimental evaluation of a hybrid desiccant air conditioning  in post and pre-cooling arrangements is studied and compared versus the  traditional vapor compression system (VCS). The system is mainly consisted  of a rotary dehumidification unit integrated with a VCS. The dehumidification  unit comprises a rotating liquid desiccant wheel. Lithium chloride is used as  the working desiccant material in this investigation. The effect of regeneration  air velocity. temperature and rotational speed of the wheel an the  performance of the system is studied. The post cooling hybrid system is found  to be an energy efficient system, it saves nearly 23% of cooling coil capacity  compared to VCS. The COP. of the post cooling arrangement is nearly  twice  that of VCS with reheat. The pre cooling arrangement ensures low dew point temperature with an increase of COP of about 70% compared to VCS with  reheat. A rotational speed of 1 rph is recommended for optimum performance.  The results of the numerical model of another work is used for comparison  with the experimental results of this study.
