Air conditioning and electric fans are common summer cooling tools. Seeing the rapid rise of electricity cost, which one is more efficient to turn on air conditioning or electric fans has caused a big discussion. Power saving is to reduce the consumption of electricity. How much is the difference between the power consumption of air conditioner and the electric fan?

The advantages and disadvantages of which power-saving air conditioner and electric fan to turn on air conditioner and electric fan to turn on which power-saving air conditioner and electric fan to turn on, of course, are much more power consumption than fan, because even the input power of air conditioner with level 1 energy efficiency of 1p is nearly 700W, while that of household fan is not more than 80W, from the above data, it can be seen that air conditioner consumes about 7-10 times more power than fan.

What is the difference between the power consumption of air conditioner and electric fan

Turn on the air conditioner and make good use of the electric fan. When it is used together with air conditioner, compared with air conditioner, electric fan only needs 5% - 10% power.

The advantages and disadvantages of which is better to use the electric fan

The advantage of using electric fan: electric fan can promote the air circulation, slow temperature reduction, not easy to get sick. The wind of electric fan can be adjusted at will, including natural wind, strong sleep wind, etc.

Disadvantages of using electric fans: if you often use electric fans, you may have sneezing, runny nose, fatigue headache, dizziness and insomnia, loss of appetite and other symptoms.

The disadvantages of air conditioning: long term in the air conditioning room will cause the sweat glands to close, affecting the normal metabolism and secretion. It may also produce 'air conditioning disease', dizziness, headache, chills, limb pain, decreased work efficiency and other symptoms. If so for a long time, it will have a great impact on human health.
