The reasons are as follows:

Complementary Advantages

     ▪ The air conditioner has a strong cooling capacity and can quickly lower the overall indoor temperature. However, it will make the air dry. Staying in such an environment for a long time, people may experience uncomfortable symptoms such as dry skin and a scratchy throat.

     ▪ The air cooler cools down through the evaporation of water to absorb heat. It can increase the humidity of the air and make the blown air softer and more comfortable. But when used alone, its cooling effect is relatively limited, especially in high-temperature and high-humidity environments. When the two are used in combination, it is possible to quickly lower the indoor temperature while relieving the air dryness caused by the air conditioner, making the indoor environment more comfortable and pleasant.

Promoting Air Circulation

     ▪ When the air conditioner is running, the indoor air flow is relatively weak, and it is easy to form a temperature stratification, resulting in uneven temperatures in different positions indoors.

     ▪ The air cooler can promote the indoor air flow, fully mix the hot and cold air, and make the indoor temperature distribution more uniform. At the same time, the air flow can also accelerate the evaporation of sweat on the human body surface, making people feel cooler, thus enhancing the overall cooling effect to a certain extent.

     However, when using them in combination, it is necessary to set the temperature of the air conditioner reasonably. It is not advisable to set the temperature too low. Generally, it is recommended to set it at about 26°C. In this way, it can not only save energy but also achieve a better level of comfort and cooling effect in combination with the air cooler.
