suction fan The cooling principle of negative pressure fans: Negative pressure fans use the cooling principle of air convection and negative pressure ventilation. Fresh air is naturally inhaled from the opposite side of the installation location - the door or window, and the hot and humid indoor gases are quickly forced out of the room. The problem of poor ventilation can be improved, and the cooling and ventilation effect can reach 90% -97%.
The powerful advantages of negative pressure fans:
1. Low investment and low energy consumption. With the same cooling rate, the one-time investment is about one sixth of that of an air conditioner, and the operating cost is about one tenth of that of an air conditioner;
2. The cooling effect is significant, able to lower the temperature to around 28 degrees Celsius, which is consistent with human body temperature. If combined with water from a well as the source of the water tank, the effect is even better, comparable to the effect of air conditioning;
3. The air is fresh and humid, with a cleanliness rate of up to 99%.
