负压排风扇的通风原理是什么? What is the ventilation principle of negative pressure exhaust fan?

Negative pressure fan ventilation principle: negative pressure fan out of the air, so that the indoor air pressure drops, the indoor air becomes thin, forming a negative pressure zone, the air due to pressure difference compensation into the room. In the actual application of industrial buildings, the negative pressure fan is centrally installed on the side of the workshop, the air inlet is located on the other side of the workshop, and the air is formed from the intake port to the negative pressure fan to form a convection blower. Hongfeng negative pressure fan indicates that during the process, the doors and windows near the negative pressure fan are closed and forced air is compensated by the door and window on the inlet side. The air is lined up and orderly from the air inlet into the workshop, flowing through the workshop, and discharged by the negative pressure fan. Thorough, efficient ventilation, ventilation rate can be as high as 99%. Through specific engineering design, according to the design of ventilation and wind speed. Any fever, harmful gas and dust smoke can be rapidly

Discharge workshop, any bad ventilation problems can be resolved at a time. Achieve the ventilation effect from a few seconds to open the fan. Negative pressure fan cooling principle: negative pressure fan cooling principle: Hongfeng negative pressure fan called negative pressure fan cooling principle mainly has the following points:

First, ventilation cooling: due to sunlight, buildings, machinery, equipment, human body and other heat sources led to the need for ventilation, the temperature higher than the workshop. The negative pressure air function can quickly exhaust the hot gas in the workshop, so that the temperature in the workshop is equal to the outside temperature, and the temperature in the workshop is not increased.

Two, air flow away body heat, air flow and accelerate the evaporation of sweat absorbing body heat, allowing the body to feel cool, cool and natural wind.

Three, the negative pressure fan only ventilation cooling effect, no refrigeration function, cool is the feeling of a human body.

With the use of four, and the water curtain, when the heat of summer temperature in the workshop can be controlled within 28 degrees celsius. But the human body can feel cool compared with air-conditioning, slightly long time at the curtain of the people will feel cold and can not stand.
