Abstract:

As there have no sufficient performance data of the regenerators under winter conditions,the corresponding design and operation of regenerators are difficult to perform. In order to solve this problem,an experimental system is established to analyze the effects of inlet air and solution parameters on the performance of regenerators under winter conditions,and the corresponding laws are drawn when aqueous LiCl is used as the regeneration solution. The results indicate that the outlet air temperature,the outlet solution temperature and the outlet air humidity ratio all increase with the inlet solution temperature,the inlet air temperature,the inlet solution mass flowrate and the inlet air humidity ratio,while they all decrease with the increase in the inlet air mass flowrate,and that,with the increase in LiCl mass fraction,both the outlet air temperature and the outlet solution temperature increase but the outlet air humidity ratio decreases. In addition,a correlation of regeneration rate and regeneration efficiency is also proposed,which is suitable for the design,operation and performance investigation of regenerators under winter
conditions.
