How much do you know about the misconceptions about household cold air fans?

　　Everyone should have heard of household cooling fans . The basic function of a cooling fan is to absorb heat from the air through water, lowering the air temperature to achieve a cooling effect. Next, let’s talk about some misunderstandings about household cooling fans.

　　What is the principle of household cooling fan?

　　Some add ice to the water in the air cooler to lower the water temperature. When the wind passes through the low-temperature water, the heat is absorbed, so you feel cooler. Another method is to absorb heat through water evaporation, making the water temperature lower. If the wind blows through the low-temperature water, you will also feel cool.

　　How much temperature can a household cooling fan cool indoors?

　　Household cooling fans can cool indoors to plus or minus 2 degrees Celsius of the lowest temperature marked on the fan body. The effect is better when the air outlet faces upward. Everyone knows the principle of heavy cold and light heat. It depends on the setting. Generally, it should not be lower than 10 degrees of the outdoor temperature. For example, when the outdoor temperature is 35 degrees, the indoor temperature should be above 25 degrees, so that it is less likely to catch a cold.

　　Is a household air cooler useful?

　　Household cooling fans (household air conditioning fans) essentially belong to the category of fans. Because their appearance is similar to a mini cabinet air conditioner, there is a water pump that can cool the air in the water cycle. It can also add ice and water to blow out cold air below room temperature, so it is called Titled air conditioning fan. Nowadays, air-conditioning fans with both cooling and heating functions are available, which can both cool down and heat up, and have more air-conditioning effects.

　　Household cooling fans are affordable in terms of price. The most expensive ones are around 600 to 700 yuan. If they are used for cooling alone, the price will be 100 to 200 yuan cheaper. The total power consumption of air conditioning fans is only 60 to 80 watts, which is the same as ordinary electric fans. Fans consume about the same amount of power. Although they cannot truly achieve the cooling effect of air conditioners, they are better than electric fans. If the weather is dry in the north, adding water and ice crystals to a household air conditioning fan can improve the temperature and maintain humidity. Especially for elderly people, the wind from a cooling fan is very gentle and just right.
