It is very hot in summer. Which is better, air conditioner or electric fan? Why?

The weather in summer is very hot, especially in the dog days, more and more people stay at home. There are two kinds of indoor summer "artifacts", one is air conditioning and the other is fan. In summer, people's life is endowed by these two appliances. Air conditioning can make cold air and make the room cool quickly. It is a necessary good electrical appliance at home. Fans are much inferior in front of air conditioners. Although it can make wind, when the temperature is high, it can't stop the "heat flow" that is coming.

In order to escape the heat, every household has installed air conditioners, but some people still insist on not turning on the air conditioners. They think that air conditioning is bad for health, and blowing fans is healthier than blowing air conditioning. We can't simply say which is better, air conditioner or fan. Generally speaking, when the temperature is not very high and the weather is not very hot, it is better to blow a fan. Because it is necessary to close the doors and windows when blowing air conditioning, if you stay in an air-conditioned room for a long time, people are prone to lack of oxygen and have symptoms such as dizziness and headache. Moreover, blowing too much air conditioning will also cause "air conditioning disease", which will easily lead to decreased immunity, and will also make people catch cold and cause colds.

However, air conditioning is not without its merits. When the weather is hot, turning on the air conditioner can not only quickly take away the heat in the room, but also have the function of dehumidification, so that human beings can create a more comfortable sense of body. When the heat is too high, the air conditioning effect is good, especially when the air humidity is high, the refrigeration mechanism that takes away the heat by evaporating sweat fails, and even the fan blows out hot air. At this time, the advantages of air conditioning are even more obvious. Air conditioning can not only make the air flow, but also reduce the dehumidification at room temperature, and create a comfortable somatosensory temperature from three aspects: wind speed, room temperature and humidity, bringing a better subjective experience.

Therefore, it is suggested that air conditioners and fans can be used alternately in hot summer to achieve good refrigeration effect and maintain indoor ventilation and air circulation.
