Experimental analysis on regeneration efficiency of countercurrent solar collector/regenerator
摘要
Abstract
A countercurrent solar solution collector/regenerator ( C/R) with experiment platform the size of 1 m( wide) ×2 m( long) ×0.35 m( high) was used for analyzing the factors influencing re-generation efficiency of solar C/R.It is found that there is an obvious two-stage distribution for re-generating solution at normal temperature.The regeneration efficiency of solution increases first and then decreases with the increase of air mass flow rates and there exists a maximum value.The regen-eration efficiency always decreases with the increase of solution flow rates.Heating solution leads to an increase of integrated regeneration efficiency;however, heating regeneration air decreases the in-tegrated regeneration efficiency.The regeneration efficiency is decreased by 0.16 by using humid air of 20 g/kg instead of using humid air of 10 g/kg.The regeneration efficiency increases correspond-ingly with the increase of the solar radiation intensity.The countercurrent solar solution C/R can op-erate better in dry air and high solar radiation conditions and a suitable air flow-rate should be select-ed to achieve better performance.关键词
