进入三伏天（sanfu, or dog days in summer)后，全国各地都开启了高温模式，室外阳光下马路煎蛋、蒸虾不在话下，高温的历史纪录也不断被刷新。暑热之下，空调、西瓜、无线网成为人们必不可少的“避暑三件套”。
This summer is already shaping up to be historically hot, increasing the chances that this year will be Earth's warmest on record. It's the time of year where air conditioning is essential for both comfort and safety.
空调肯定是要开的，然而温度设置却成了问题。最近，话题登上热搜，网友感叹“再亲密的人也可能在空调开多少度这件事上有分歧”。
有网友直呼：找对象一定要找空调度数合得来的，比如空调开28°C，你需要用被子裹得严严实实，而你对象还在冒汗。

还有网友称：一个人变老的真正标志，从空调要开26°C往上开始。年少轻狂的时候开到最低温度都不会觉得冷，现在只要低于26°C，膝盖就会觉得不舒服。
那么，空调究竟应该开多少度才能兼顾降温、省电、省钱、不伤身呢？
The question that does come into play is whether it’s more important to keep your monthly energy bills down or keep your home’s thermostat set at a comfortable temperature. As such, you may be weighing your options and asking yourself the same question that other homeowners have asked repeatedly: To what temperature should I set my air conditioner in summer?
我国国务院2006年发布的《国务院关于加强节能工作的决定》文件中明确规定：所有公共建筑内的单位，包括国家机关、社会团体、企事业组织和个体工商户，除特定用途外，夏季室内空调温度设置不低于26°C，冬季室内空调温度不高于20°C。
夏季空调26℃的标准，主要是从节能角度和健康角度两方面综合平衡后的结果。一般情况下，空调制冷时温度调高1℃，平均可节省近10%的电能，与此同时，从医学角度讲，室内室外温度差一般保持在5-10℃为宜，温差过大会使人更容易患感冒、出现不适症状，26℃刚好能够在保证体感温度适宜的前提下节省电能，达到二者的平衡。而在日常生活中，23℃-26℃是比较让人舒适同时耗电量不会太大的温度。
Set thethermostatto the highest temperature that is comfortable for you and your family. Each degree higher can save you a significant amount of money on your energy bills. As per some recommendations, 23 degrees to 26 degrees is the right temperature option that is comfortable and yet pocket friendly.
thermostat: /ˈθɜːməstæt/ 温度自动调节器；恒温器
在此范围之内，根据一天中气温和作息的不同时段，我们可以适当调整空调度数，达到更加舒适节能的状态。
Additionally, you can also adjust the temperature based on your daily schedule.
下午时段往往是一天中最热的，此时用电量也最高，此时可以适当避开用电高峰，同时控制室内外温差，将空调温度适当调高。专家表示，当室外温度很高时，即便室内温度小幅度提高，人们的身体依然会感到十分舒适。
The afternoon period is often the hottest time of the day, and the electricity usage is at its peak. It is advisable to avoid excessive electricity consumption during this time. Additionally, it is recommended to control the temperature difference between indoor and outdoor environments by slightly raising the air conditioning temperature. Experts suggest that even with a slight increase in indoor temperature during hot outdoor conditions, people will still feel quite comfortable.
除此之外，夜间温度通常要低一些，同时人体处于睡眠状态，此时可以将空调温度设置为28℃左右，既节能又健康舒适。还可以设置定时模式，避免夜间着凉。
Furthermore, during the night, temperatures usually drop, and individuals are in a sleeping state. It is recommended to set the air conditioning temperature to around 28℃, as it is both energy-efficient and provides a healthy and comfortable sleep. Using a timer mode can also help prevent getting too cold during the night.
除了温度设置之外，夏季使用空调还有这些小妙招。
平时要注重空调设备的清理和维护，这可以延长空调使用寿命，提高空调性能效率。一方面要定期清理、更换滤网，以保持空气通常流通，另一方面，要保证空调外机周边没有堵塞物，保证室内外的循环。
You should give special care about regular maintenance and cleaning of your air conditioning system. It can greatly improve ACs efficiency and reduce energy consumption. Clean or replace air filters regularly to ensure proper airflow and remove dust and debris that may hinder performance. Keep the outdoor unit free from obstructions like leaves or debris, allowing for better air circulation.
避免使用洗碗机、烤箱、烘干机这些家电的使用，因为它们会提高室内的湿度和温度，加大空调的负担。
Avoid using appliances such as dishwashers, ovens, and dryers, which can make spaces hotter and more humid and force your air conditioner to work harder.
此外，空调吹久了也要给房间定时通风、注意皮肤保湿，这样才能健康又舒适地过夏天。空调虽然舒适，请不要贪凉哦。
你开空调一般多少度呢？
