style="letter-spacing:0.5px;">虽然空调不工作时不耗能，但启动阶段的能耗会很高。<strong>重启次数多了，总能耗会超过空调一直开着的能耗。而且空调工作时间越长，这种对比越明显</strong>。</span></p><p style="margin-left: 16px;margin-right: 16px;"><span

style="letter-spacing:0.5px;">华东师范大学物理与电子科学学院工程师崔璐2023年在上海科技馆微信公众号刊文分享了夏季开空调的省电秘诀。</span></p><p style="margin-left: 16px;margin-right: 16px;"><strong><span style="letter-spacing:0.5px;">南方的三伏天又热又潮湿，需要打开空调的除湿模式</span></strong><span style="letter-spacing:0.5px;">，保证室内湿度在45％~65％，能提升体表的舒适度且有利于人体健康。如果室内初始温度较高，可以<strong>先开制冷模式，待房间温度下降后再改为除湿模式</strong>，这样既能省电又能达到除湿制冷的效果。</span></p><p style="margin-left: 16px;margin-right: 16px;"><strong><span style="letter-spacing:0.5px;">北方的大部分城市夏季室内炎热但并不潮湿，应选择制冷模式</span></strong><span

16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">北京安贞医院呼吸与危重症医学科主任医师万钧2024年6月在CCTV生活圈微信公众号刊文指出，注意这8点吹空调才健康。<span style="font-size: 12px;"><sup>③</sup></span></span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">1. 定期清洗空调</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">长时间不用的空调在使用前最好及时清理，建议每半个月清理一次空调机的滤网，一来是为了获得洁净的空气，二来长期使用后滤网上面会聚集灰尘，导致进气和出气不畅，降低空调的性能，耗电量也会增加。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">2. 避免骤冷骤热</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">我们机体的适应力是有限的，比如从很热的环境中突然进入到空调房内，或从空调房内突然进入很热的环境，这种情况下机体很难调适，容易出现免疫功能紊乱、免疫功能低下等问题。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">3. 保持室内保湿</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">恰当的湿度对于呼吸道黏膜、皮肤等免疫功能的保存很有帮助，所以要保持室内有一定湿度，避免又冷又干。可以适当饮水补充水分，也可以在空调出风口下方放置一盆水来改善湿度，房间内湿度控制在 40%～60%为宜。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">4. 温度不宜设置太低</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">空调温度不宜设置太低，室内外温差也不宜过大，过大会加重体温调节中枢负担，也很容易造成头晕、皮肤干燥、口干舌燥等不适，而且还耗电，一般最适宜温度为26℃~28℃。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">5. 定时开窗通风</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">开空调会使空气不流通，空气质量下降，容易引起鼻塞、喉咙干、打喷嚏等呼吸道不适。因此，应该注意时常换气，建议2～3小时左右开一次窗，每次通风约10～15分钟，保证室内空气新鲜。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">6. 避免直吹身体</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">避免冷风直吹身体，尤其是头面部、膝盖、小腹、腰部等对温度比较敏感的部位。如果直接对着头颈部吹，头皮温度下降，容易引起脑血管收缩，对于有心脑血管疾病的老人而言，严重时可诱发中风。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">7. 风向朝上更制冷</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">开空调制冷时，最好把空调风向朝上，让冷空气由上而下循环。制热时，则让空调风向朝下。一般来说，冷空气向下走，而热空气反之，因此这样可充分利用冷热空气自身的物理特性，自然交流。</span></p><p style="margin-left: 16px;margin-right: 16px;line-height: 1.6em;"><span style="font-weight: 700;color: rgb(2, 30, 170);text-shadow: none;letter-spacing: 0.5px;">8. 老人也要及时开空调</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">老人可能在“不觉得热”的情况下出现“隐性中暑”。随着年龄升高，老年人的皮肤温度感受器敏感性下调，对外界的温度、湿度的体感变得不明显。所以即便室温偏高，他们可能感觉不到很热，也就无法及时降温补水。</span></p><p style="margin-left: 16px;margin-right: 16px;"><span style="letter-spacing:0.5px;">但实际上，由于他们的身体体温调节功能和适应能力下降，长期处在高温高湿、不通风的室内环境，很容易出现脱水、散热不佳、体内电解质紊乱的症状，从而中暑。因此及时开空调、保持室内适当通风。</span></p><section style="margin-right: 16px;margin-left: 16px;outline:
