can you believe that the air conditioner is as low as one kilowatt hour a night? I believe that many netizens who shop for home appliances in shopping malls have noticed that many air-conditioning salesmen will publicize their air-conditioning "one electricity a night" and only one electricity a night. Is this really true? Is it a gimmick for businesses to cheat consumers? Today, let experts bring real secrets for the general public. On June 22, Dong Mingzhu talked about Meidi, his old rival, and thought it was dishonest. For example, the advertisement of one kilowatt hour electricity in one night's air conditioner was nonsense. Recently, Gree sued Midea for infringement, claiming 50 million yuan.
The optimal value of laboratory energy consumption is not equal to the actual power consumption. If the "one hour per night" air conditioning belongs to level 1 energy efficiency, it is certainly relatively energy-saving, but it is almost impossible to achieve 8 hours per hour. For the air conditioning products with energy efficiency level 1, according to the data on the energy efficiency label, it can be calculated that the power consumption per hour is 0.4KW, which is equivalent to one kilowatt per hour in two and a half hours. As for achieving "one kilowatt hour per night" under specific conditions promised by individual brands, it is to confuse the power consumption during actual use with the optimal energy consumption under specific conditions in the laboratory, which is misleading to consumers.

Xia Chuanyou, President of Anhui Information Appliance Industry Association, thinks that at present, the air-conditioning market is in fierce competition, and the "one night electricity" is more about the marketing strategy of businesses. Air conditioning manufacturers put forward the concept of energy saving to meet the energy-saving needs of consumers and compete for market share, which is to mislead consumers with laboratory data.

The output power of 1.5p air conditioner is 3200W. We conservatively estimate that the energy efficiency level is the lowest level 5 energy efficiency 2.6, so the input power is 3200W / 2.6 = 1230w. One hour is 1.23 kilowatt hour. 24 hours a day is 1.23 * 24 = 29.52 kilowatt hour. Now, one kilowatt hour is 0.5 yuan, which needs 29.52 * 0.5 = 14.76 yuan.
It is said that the air conditioner can not be heated by electricity. Generally, the electric heating of air conditioner is 600W, 0.6 kwh per hour, 14.4 kwh in total in 24 hours, 14.4 * 0.5 = 7.2 yuan in total. Then the electricity charge for one day of heating and air conditioning is 14.76 + 7.2 = 21.96 yuan.
