How many degrees can the air conditioner be set to save energy?

How much should the air conditioner be turned on to save energy? Research shows that the most suitable temperature for air conditioners is not necessarily 26°C or 28°C, but setting it higher does save energy. According to an actual measurement study of air conditioners in a room in Maoming, Guangdong in 2015, if the set temperature of the air conditioner is lowered from 26°C to 25°C, the power consumption will increase by 47.89%. If the set temperature of the air conditioner is lowered from 27°C to 25°C, the power consumption will increase. The volume will surge by 134.35%. Of course, the power consumption of an air conditioner is affected by many parameters, such as the temperature, humidity, wind speed and other meteorological conditions in the area, the energy efficiency level of the air conditioner itself, the refrigerant used, the structure of the air conditioner, etc. If the set temperature rises by one degree, it will bring The impact is not necessarily the same, but many experiments have shown that the general trend is still "turn up one degree and save a little more power." In addition, directing the air conditioning vents towards the roof will also help to cool down the whole house.
