近期多地持续高温，加上即将到来的三伏天，一些地方气温突破40℃。如何使用空调，成为热门话题。



其实日常空调温度建议设置在26℃-28℃的“黄金区间”，这个区间不会因为温度太低导致空调病，体感最舒适，而且也相对省电。白天25℃-26℃体感舒适，夜间睡眠可升至27℃-28℃，避免后半夜过冷。

但总的来说，别舍不得开空调，记住这几点，空调既省电又舒服。

Record-breaking heatwaves with temperatures exceeding 40 C have hit multiple regions across China, sparking widespread discussions on efficient air conditioner usage. Experts suggest maintaining temperatures at 25 C-26 C during daytime and 27 C-28 C at night for optimal comfort in summer. Key methods can enhance efficiency while reducing energy consumption.

模式选择技巧：

睡眠模式、除湿模式、节能模式

1. 睡眠模式：有些品牌空调会有专门的“睡眠模式”，夜间开启后，空调自动逐步升温并降低风速，省电且能避免感冒。

2. 除湿模式：除湿模式潮湿地区首选，当湿度>60%时（如南方梅雨季），除湿模式比制冷省电30%，同时体感温度下降2℃-3℃。干燥的北方地区则不建议，避免呼吸道太干不适。

3. 节能模式：有些品牌的空调可选择“省电模式”，也能减少晚上长时间开空调的耗电量。

Modern air conditioners feature specialized modes including sleep mode, dehumidification mode, and power-saving mode. Activating sleep mode at night gradually raises temperatures and reduces fan speed, conserving energy while preventing cold-related discomfort. Dehumidification mode benefits humid regions, but may cause respiratory dryness in arid northern areas. Power-saving mode significantly cuts electricity usage during extended nighttime operation.

搭配风扇降温：

“空调+风扇”组合省电又凉快

“空调+风扇”组合：日常屋里可搭配空气循环扇/风扇，让屋内空气流动起来，风扇促进冷气循环，体感温度降2℃-3℃。比如：空调设28℃+风扇≈体感26℃效果。



建议风扇摆放位置：置于空调下方，将冷风吹向房间深处，可选择柔风/自然风。

Air circulator fans enhance cooling efficiency when paired with AC units. Positioning fans beneath air conditioners to direct cool air deeper into rooms improves air circulation, lowering perceived temperatures by 2 C-3 C.

空调风向朝上吹：

冷空气会自然地向下沉降

很多人不开空调还有一个原因，觉得空调的风吹在身上不舒服，其实空调风向可以设置成朝上吹，或上下摆风。这是因为冷空气比热空气密度高，会像水一样自然向下沉降。当空调冷风向上吹时：冷风先抵达天花板→ 缓慢向下沉降 → 均匀扩散至整个房间。

这样避免冷风直吹人体，减少“头痛/关节痛”，同时实现全屋温度均衡。

Adjusting airflow direction solves discomfort from direct drafts. Setting vents to blow upward or using oscillation mode allows cool air (which naturally sinks downward like water due to higher density) to distribute evenly. This prevents health issues like headaches/joint pain while balancing room temperatures.

短暂外出不关机：

外出＜1小时不建议关空调

重启空调的耗电相当于持续运行20-30分钟。外出＜1小时的情况，建议不要关闭空调，空调温度调高1℃-2℃即可。

For brief absences under one hour, experts recommend keeping units on while raising temperatures by 1 C-2 C instead of turning them off. Restarting consumes equivalent energy to 20-30 minutes of continuous operation.

专家介绍，频繁开关空调还可能给压缩机造成较大压力，导致其使用寿命缩短。想要空调省电，更有效的做法是：尽量减少室内和室外的热交换，空调不用的时候彻底断电；建议使用变频空调。
