font-size: 17px;">电扇本身不会让室温降低，但吹着电扇会让人感觉更凉。这种现象就是风冷效应，它是因为风加快了人与环境的热交换，促进了皮肤表面水分的蒸发。</span></section></section><section style="margin-bottom: unset;"><section style="margin-left: 8px; margin-right: 8px; line-height: 1.75em; text-indent: 0em;"></section><section style="margin-left: 8px; margin-right: 8px; line-height: 1.75em; text-indent: 2em;"><span style="font-size: 17px;"><span style="color: #3f3f3f; letter-spacing: 1px;">这种效应能够明显改变人的体感温度，让人在更高的室温下也不觉得热。</span><span style="letter-spacing: 1px; color: #2bb3f1;"><strong>和无风相比，人在风扇吹拂时能接受的室内温度可以提高 2~3℃</strong></span><span style="color: #3f3f3f; letter-spacing: 1px;">——比如说，如果原本是 26℃ 觉得舒适，吹上风之后就可以坚持到 28℃ 以上才觉得热。</span></span></section><section style="margin-left: 8px; margin-right: 8px; line-height: 1.75em; text-indent: 0em;"></section><section style="margin-left: 8px; margin-right: 8px; line-height: 1.75em; text-indent: 2em;"><span style="font-size: 17px;"><span style="color: #2bb3f1;"><strong><span style="letter-spacing: 1px;">开着电扇让人不再需要那么低的室温，因此这时可以把空调设定温度调高——这就是省电的关键。</span></strong></span><span style="color: #3f3f3f; letter-spacing: 1px;">空调温度每改变 1℃，电能消耗大约会相差 5%~10%。开风扇有望让温度设置提高 2℃ 甚至更多，而运行风扇所需的电能又在空调耗电量的 5%以下。这样算下来，在达到相同体感温度时，空调+电扇的用电量就能比只用空调更少。</span></span></section><section style="margin-left: 8px; margin-right: 8px;

color: #2bb3f1;"><strong>不过，如果能充分调高空调温度和减少开空调时间，这种方案的节能潜力确实不小。</strong></span></span></p><section style="margin-left: 8px; margin-right: 8px; line-height: 2em; text-indent: 0em;"></section><p style="margin-left: 8px; margin-right: 8px; text-indent: 2em; line-height: 2em;"><span style="font-size: 17px;"><span style="color: #3f3f3f; letter-spacing: 1px;">在 2022 年，一项发表于《柳叶刀-全球健康》的研究以澳大利亚的情况为例进行了计算。这项研究给出了比较乐观的估计：</span><span style="letter-spacing: 1px; color: #2bb3f1;"><strong>如果把只用空调改成空调与风扇结合，将有望使全年用于室内制冷的能量减少多达 76%。</strong></span></span></p><section style="margin-left: 8px; margin-right: 8px; line-height: 2em; text-indent: 0em;"></section><p style="margin-left: 8px; margin-right: 8px; text-indent: 2em; line-height: 2em;"><span style="font-size: 17px;"><span style="color: #3f3f3f; letter-spacing: 1px;">在模型计算之外，也有人对这种节能方案进行过实地测试。例如，在美国加利福尼亚，就有研究者在十栋有空调的建筑内安装了能够根据温度自动运行的吊扇，并鼓励使用者将空调温度调高。结果，在 4 月至 10 月的制冷季里，</span><span style="letter-spacing: 1px; color: #2bb3f1;"><strong>风扇的加入使空调压缩机能耗节省了 36%，同时风扇的能耗仅有压缩机的 2%。</strong></span></span></p><p style="margin-left: 8px; margin-right: 8px; line-height: 1.75em;"> </p></section><section style="margin-bottom: unset;"><section style="font-size: 16px;
