Negative pressure fan is a kind of ventilation and cooling equipment, which can significantly reduce the temperature of the plant. Through the professional special fan angle design, external dimension design, air volume and pressure design, motor matching design and other procedures, we have produced a kind of indoor ventilation and cooling equipment with large air volume and low noise. Today, let's know if the negative pressure fan can cool down the plant.
So we can see that the most important word is negative pressure fan. When the negative pressure fan is powered on, the mechanical kinetic energy will quickly generate a strong exhaust volume, which will quickly discharge the indoor high temperature, muggy and stagnant air to the outside. At this time, the indoor and outdoor air will produce a pressure difference, and the indoor negative pressure state will be formed quickly.
Naturally, the outdoor fresh air with strong pressure will be introduced into the room for forced convection exchange. Generally speaking: a relatively closed space or container, if the air is pumped out, the low pressure will be formed in the space, which is lower than the air pressure outside the space. The situation formed in the container is negative pressure. Only by the mechanical power of the negative pressure fan, can the strong ventilation in the workshop quickly cause the negative pressure in the workshop, and it is sufficient to use the doors and windows of the workshop as the air inlet Enough to let the outside air into the factory to form air convection, this is called the working principle of negative pressure fan ventilation.
Negative pressure fan is a common ventilation and cooling equipment with high efficiency. From its working principle, we can see that its main work is to cool the heat.
Air flow can take away heat from the human body. When air flow accelerates sweat evaporation and absorbs heat from the human body, it will make the human body feel cool. What needs to be explained is that the negative pressure fan only has the function of ventilation and cooling. It is not an air conditioner. It does not have the refrigeration function of a compressor, so the cooling is limited.
Cooling is our feeling of temperature. It is ignorant to say how much the negative pressure fan can reduce the temperature. How much the negative pressure fan can reduce depends on the speed of the exhaust air, the indoor hot air discharge and the temperature The speed of outdoor cool air exchange and the number of negative pressure fans installed. If you want a better cooling effect, you should use the negative pressure fan + cooling wet curtain.
The negative pressure fan is mainly responsible for the rapid exhaust of hot air. The cooling wet curtain cools the air exchanged into the room to make the indoor air cooler. We have done many tests. When it is very hot in summer, if we use the negative pressure fan + cooling wet curtain, the car can be cooled The temperature in the room is controlled within 28 degrees Celsius. The cool feeling of the human body can be compared with that of the air conditioner. People who face the water curtain for a longer time will feel cold and can't stand it.
