针对网络热议的空调省电话题，电力部门给出了明确的建议。[1]根据央视新闻报道，短暂外出（外出时间小于1小时）时无需关闭空调，而是将温度调高1到2℃比频繁启停更加省电。[1]不过这一方案仅适用于外出时间较短的情况，若长时间离家如上班一整天，则不如回家后重新开机更划算。[1]
国网北京市电力公司同时推荐了一系列夏日空调使用方案。[1]在温度设置上，26℃至28℃被列为"黄金区间"，白天体感舒适温度建议为25℃至26℃，夜间睡眠时则设置在27℃至28℃。[1]为快速降温，用户可在刚回家时先将温度设至23℃快速冷却，30分钟后调回26℃。[1]除了温度调节，配合使用电扇可使体感温度下降2至3℃，同时拉窗帘挡住强光也有助于降低空调负荷。[1]
China's power authorities have weighed in on the viral claim that leaving air conditioning on continuously saves more energy than turning it off and on frequently.[1] According to reporting by CCTV News, the power department clarified that for brief absences of less than one hour, it is more efficient to leave the air conditioner running while raising the temperature by 1 to 2 degrees Celsius rather than repeatedly shutting it down and restarting it.[1] However, for extended periods away from home, such as a full workday, turning the unit off and restarting it upon return proves more economical.[1]
State Grid Beijing Electric Power Company has offered practical guidance for summer air conditioning use.[1] The company recommends setting temperatures within a "golden range" of 26 to 28 degrees Celsius, with daytime comfort around 25 to 26 degrees and nighttime sleeping temperatures of 27 to 28 degrees.[1] For rapid cooling upon arriving home, the department suggests initially setting the temperature to 23 degrees for approximately 30 minutes before adjusting back to 26 degrees.[1] Additionally, using a fan can reduce the perceived temperature by 2 to 3 degrees, and drawing curtains to block strong sunlight offers complementary energy savings.[1]
