摘　　要： 根据一个事实 :空调系统处于峰值负荷的时候 ,通常是太阳能处于最丰富的时候 ,将太阳能集热器技术、转轮除湿技术和常规压缩制冷技术相结合 ,提出了一个太能能驱动除湿转轮辅助中央空调系统 ,并进行了可行性分析。该系统不仅可以降低冷水机组设计负荷的要求 ,实现“削峰”目的 ,相应地可以选择较少规模机组 ,而且在没有太阳能供应的时间区段内仍然有很强的适应性。对比实验表明 ,除湿转轮处理湿负荷的能耗一般是表冷器处理湿负荷的 4 0 %以下 ,节能效果显著。 Based on the fact that solar energy is usually most abundant when the load on an air-conditioning(AC) system peaks,and combining with the technologies of solar collectors,rotary dehumidifiers and conventional chillers,a design for a central AC system assisted by a solar-driven rotary dehumidifier was proposed.The feasibility of implementing was investigated,and reached the conclusion that this system can reduce the design load requirement of the chiller and hence achieve peak shaving and downsize the chiller.It is also applicable when no solar energy is available.Furthermore,the design proposal has been verified by an experiment contrasting the results of the moisture load removal by a rotary dehumidifier and by a surface-cooler.The results showed that the energy consumption of the former was generally less than 40 percent of that of the latter,so the energy efficiency was improved significantly.
