How is the cooling effect of the air conditioner fan?

The cooling effect of air conditioning fans is better than that of electric fans, but worse than that of air conditioners. It has the following main disadvantages:

The cooling principle of the air conditioner fan is the fan plus water cooling, which uses spray water to absorb the heat of the air and blow out cold air. In a small room, the cooling may be good, but in a large room, the space for water vapor to diffuse is limited, and the overall cooling effect is not good enough.

Air conditioning fans can only reduce the temperature of the original environment by 10 degrees in a small area. If the ambient temperature is around 35 degrees, the lowest temperature that can be reached after using air conditioning fans may be 25 degrees. Therefore, if the ambient temperature is as high as 40 degrees, using air conditioning fans to cool down will feel very useless and the cooling effect will not be good.

Using an air-conditioning fan requires water and ice crystals, but the water tank of the air-conditioning fan is limited. It is troublesome to add water and replace ice crystals several times a day.

To use an air-conditioning fan, you must have a refrigerator at home to freeze ice crystals. If you don't have a refrigerator at home, or the refrigerator cannot freeze, then it is not recommended to buy an air-conditioning fan.

Is the air conditioner harmful to the human body?

It is harmless to the human body under normal use.

Regular air-conditioning fans on the market are harmless to the human body under normal circumstances. They can also cool the human body and relieve the discomfort of summer heat. However, if used improperly, they will cause certain harm to the body, such as the following:

Long-term use of air-conditioning fans will increase the moisture in the body, thus causing heavy moisture, often accompanied by sore limbs, cold hands, etc., especially for people with heavy moisture themselves.

Improper use of air-conditioning fans will increase the coldness in the body. For patients with arthritis, it will induce a recurrence of arthritis and may also cause rheumatism.

If the air conditioner is on for too long, the human body cannot withstand the low temperature and will catch a cold, often accompanied by runny nose, diarrhea and other uncomfortable symptoms.

How to use the air conditioning fan correctly

Note that the air conditioner fan should be placed horizontally and should not be tilted during use. Before use, check whether the power supply of the socket is consistent with the parameters on the fan nameplate.

It is necessary to fill the fan with clean water before use, for new machines or air conditioners that have been out of service for a long time. The water level can be observed through the water mark to control the amount of water added. The power plug should be unplugged before adding water to prevent damage to the electrical components. The water level to be filled should rise to the "highest" position, and it should not be overfilled. After filling with water, close the fan door. When used for cooling, pay attention to the water mark. When the water level drops to the "lowest" position, water should be added, otherwise the cooling effect will be lost.

Every night, the general air conditioning fan is equipped with two ice crystals. Put one of them in the refrigerator at home for a period of time, take it out and put it in the water tank the next day for better effect.
