# Does the Cooling Humidity of Eco-Friendly Air Conditioners Affect Indoor Spaces and the Human Body? You Will Understand After Reading This

Customers often ask us about eco-friendly air conditioners (evaporative coolers): isn’t the humidity produced by using an eco-friendly air conditioner quite high? Will frequent exposure to the airflow affect your health? Will it make the indoor workshop damp? So when introducing the working principle of eco-friendly air conditioners to some new customers, they often change color at the mention of “moisture,” as if humidity were some kind of monster to be avoided. So is humidity really that frightening? Does using a cooling fan affect human health? The answer is that cooling fans do not have any negative impact on people. On the contrary, the effect of cooling fans on the human body is positive.

1. Cooling Principle
The cooling principle of eco-friendly air conditioners is to remove the surrounding heat through water evaporation. When outside air enters the eco-friendly air conditioner, the cooling pad absorbs most of the heat. The cool air is delivered into the room through the eco-friendly air conditioner’s air supply system, achieving the purpose of cooling.

2. Humidity Regulation
Rundong eco-friendly air conditioners can regulate humidity, adjusting the humidity in workplaces that need increased air humidity. High-quality eco-friendly air conditioners use 5090-type cooling pads with an evaporation efficiency of 86%. Under normal ventilation conditions, the ambient humidity will increase by about 10-15%. In summer outside the plum rain season, the average temperature is around 35 degrees and the average humidity is around 56%. This climate is very suitable for air coolers. Under the above meteorological conditions, the outlet air temperature is about 26-28 degrees. Blowing onto the human body surface, it feels even more comfortable.

3. Suitable Humidity Has No Adverse Effect
Scientific research shows that a relative humidity of 75% is suitable for people. The humidity in China’s Jiangnan region is higher than in the northwest, but not as high as in Guizhou and Chongqing. The suitable temperature and humidity environment makes people’s skin there soft, smooth, fair, and lustrous. Hence, since ancient times there has been the saying about Jiangnan beauties. It can be seen that the increase in ambient humidity when using cooling fans only serves to regulate air humidity. Naturally, it will not affect human health. Therefore, we should view the impact of humidity on people correctly.
Although eco-friendly air conditioners have a remarkable cooling effect, allowing you to immediately enjoy fresh and cool air, they are favored by manufacturing and processing enterprises because they increase air humidity while cooling, which has no impact on production workshops that do not require constant temperature and humidity.
Rundongfang eco-friendly air conditioners have passed CRAA certification, China 3C, China Electrician CB, European Community, German GS, Korean KV-MARK, Japanese L-MARK, American CETL, and many other authoritative certifications such as ISO 9001:2000, and hold multiple product invention patents and certification certificates.
