1. Negative pressure fan is a device that uses the principle of negative pressure to forcefully remove hot air, exhaust gas, and dust from indoors and accelerate air flow. Air flow takes away human body heat, accelerates sweat evaporation and absorbs human body heat, making the body feel as cool as natural wind;
twosuction fan Ventilation and cooling: Due to sunlight shining on buildings, machinery and equipment, human bodies and other heat sources, the temperature in places that require ventilation is higher than outdoors. Negative pressure fans can quickly eliminate indoor heat, keeping the indoor temperature level with the outside temperature, and preventing the temperature in the workshop from rising;
3. Negative pressure fans only have the function of ventilation and cooling, without the function of cooling;
4. When used in conjunction with a negative pressure fan and water curtain, the temperature in the workshop can be controlled within 28 degrees Celsius during hot summers. But the coolness of the human body can be compared to air conditioning.
Introduction to the application of negative pressure fan:
1. Fan used in conjunction with wet curtain: Negative pressure fan used in conjunction with wet curtain for workshop cooling. Both wet curtain and negative pressure fan systems can reduce workshop temperature and maintain a certain level of humidity;
2. Negative pressure fan used as exhaust fan: Generally, the efficiency of exhaust fans is relatively poor. One exhaust fan can only blow a few people, while negative pressure fans are not. No matter where you place them at that height, using four fans in a 1000 square meter workshop can achieve the effect of air blowing for the entire workshop;
