摘要
提出并设计了一种采用翅化表面吸热板,溶液流程分为集热加温段与集热再生段的太阳能溶液除湿空调集热再生器,采用等温模型与集总参数法对其做了初步的理论分析.分析结果表明:翅化表面吸热板可通过扩大传热传质面积与增进局部紊流强度来实现传热传质过程强化;溶液流程二段式布置可保证传质方向以及实现近似于等温的再生过程;在一定范围内,增加吸热板的翅化比有利于提高太阳能利用系数.
A new kind of collector/regenerator for solar liquid desiccant air conditioning system is presented, which adopts a fin-forming absorber plate and where the liquid desiccant flow-through process is divided into two stages, preheating stage and regenerating stage. Then the theoretical performance analysis is provided by using the isotherm model and the lumped parameter method. The main results are as follows.. （1） the fin-forming absorber plate can increase heat and mass transfer areas and promote turbulence, so that it significantly enhances heat and mass transfer between the air and the liquid desiccant; （2） the two-stage process of liquid regeneration can ensure the mass transfer direction and achieve the approximate constant temperature regeneration process; （3） an increase of the absorber plate fin ratio within a certain range can help to improve the utilization factor of solar energy.
