摘要
为深入分析太阳能吸附制冷变压工况对制冷性能的影响,在管道泵强化传质太阳能吸附制冷系统实验平台基础上,开展对太阳能吸附制冷系统强化传质变压工况下解吸量、制冷量的实验分析,并与自然传质恒压工况进行对比,获得强制循环下太阳能吸附制冷系统变压制冷特性。实验结果表明:在同等加热量情况下系统运行10 h,吸附制冷系统加装强化传质管道泵后,白天加热解吸阶段随着吸附床温度的提高,吸附床在强化传质工况下与自然传质工况下相比压力降低约10 kPa,从而使得强化传质比自然传质解吸率提高21.7%、解吸量提高1000 mL,制冷循环系数COP_(solar)提高18.8%。
In order to analyze the effect of a solar-driven adsorption refrigeration under variable pressure condition on refrigeration performance,a solar-driven adsorption refrigeration system with a pipeline pump to enhance mass transfer has been proposed. The experiments had been conducted and the results of the amount of desorption and cooling capacity of the solar adsorption refrigeration system were analyzed under the conditions of enhanced mass transfer with variable pressure. The experimental results had been compared with the natural mass transfer and constant pressure conditions.The variable pressure refrigeration operating characteristics of the solar adsorption refrigeration system were obtained.The experimental results showed that the system with enhancing mass transfer could increase the mass of desorbed refrigerant by 21.7% compared with a natural desorption refrigeration system,the desorption amount and the coefficient of performance(COP_(solar))could be increased by 1000 mL and 18.8% respectively,with the same heating duration of 10 h.
