新型节能配电变压器的经济性分析及选型建议（Economic Analysis and Application Advice onthe New Types of Energy-Saving Distribution Transformer ）
配电变压器 节能 应用研究
2010/8/17
S13型、S14型和非晶SBH15型变压器都是非晶合金变压器，是具有节能效果的变压器新产品。文章分析了这些变压器的损耗特性，并采用TOC法比较其技术经济性。从与S11型变压器比较的结果可知，非晶SBH15型的空载损耗最低，S13型变压器的负载损耗最低，因此，在使用这些变压器替换已有的变压器时，要根据变压器的用途和费用加以选型。
太阳能技术及其并网特性综述（Overview of Solar Energy Technology and Its Integration Issues）

龙眼压差通风预冷装置风速控制与能耗分析（Air Velocity Control and Energy Analysis in Forced-air Pre-cooling Device of Longan）
龙眼 压差通风预冷 能耗
2009/5/22
针对龙眼的物理特性，设计了一套龙眼压差通风预冷试验装置。根据果蔬压差预冷7/8时间特性，通过试验得到了龙眼包装箱压差与风速关系以及异步电动机频率与风速关系。进一步研究龙眼压差预冷装置能耗与风速关系可知，对于龙眼果实，较小的风速预冷能耗较小，预冷时间较长；当预冷时间按要求设定时，在风机允许范围内控制风速按一定规律递增，直到龙眼终止温度，可以在设定时间内完成龙眼预冷，且能耗最小。
