|
摘要
为了优化太阳能吸附制冷系统,提高其制冷性能,构建基于强化传质作用的太阳能吸附制冷系统,并在模拟环境下对系统在强化传质模式下和自然传质模式下的制冷性能进行实验研究和对比分析。实验结果表明:在同等辐射能输入条件下,系统在强化传质模式下的制冷效率比在自然传质模式下的制冷效率有明显提高,效率最大可提高58.0%,且强化传质模式下系统的制冷性能较为稳定,能量利用率高;此外,强化传质模式下的系统还可解决自然传质模式中不可避免的间隙制冷问题。研究结果可为太阳能吸附制冷系统的优化设计提供新的思路。
In order to optimize the solar adsorption refrigeration system and improve its refrigeration performance,asolar adsorption refrigeration system based on intensified mass transfer function was proposed and established. Theexperimental research and comparison analyses of the refrigeration performances under intensified mass transfer modeand natural mass transfer mode were conducted in a simulated environment. The experimental results show that under thesame solar radiation,the refrigeration efficiency of intensified mass transfer mode has a significant improvement than thatof natural mass transfer mode,the improved maximum efficiency can reach to 58.0%;the refrigeration performance ofthe system under intensified mass transfer mode is more stable,the energy utilization rate is higher;in addition,thesystem under intensified mass transfer mode can solve the inevitable issue of clearance refrigeration in natural masstransfer mode. The research results can offer a kind of new mentality for design and optimization of solar adsorptionrefrigeration system.
