An air curtain is an invisible barrier of air that separates two different environments, such as indoor and outdoor spaces. It works by using high-speed fans that blow a stream of air down across the opening to create this barrier. The force of the air creates a seal over the entrance, preventing insects, dust particles, and pollutants from entering.
There are three types of ventilation methods for exhaust fans: exhaust type, suction type, and combined type. The exhaust type enters the air from the natural air inlet and discharges the dirty air through the exhaust fan; the suction type sucks in fresh air through the ventilation fan and discharges the dirty air from the natural exhaust port; the combined type is that the suction and exhaust are both completed by the ventilation fan.
An exhaust fan is an air conditioner that enables an electric motor to rotate the exhaust blades. Drives airflow to exchange indoor and outdoor air. The exhaust fan can use air convection to keep the indoor air in a negative pressure state, form suction, and then continuously inhale fresh air from the outside, discharge the hot and dirty indoor air, and achieve the effect of adjusting the indoor temperature and humidity. Indoor ventilation and cooling can be achieved. The role of the exhaust fan The main function of the exhaust fan is to discharge indoor dirty air and inhale fresh outdoor air.
Exhaust fans, also known as negative pressure fans, negative pressure fans, etc., use air convection to keep the room in a negative pressure state all the time, forming a suction force, continuously inhaling outdoor air, and discharging indoor sultry air, thereby to achieve ventilation, cooling effect.
The exhaust fan can quickly discharge the hot indoor air, and suck the air on the other side of the outdoor into the room, so that the temperature is equal to the outside temperature, and the temperature in the workshop will not rise. In the process of air flow, the body heat will be taken away, and the air flow will accelerate the evaporation of sweat and absorb the body heat, thus making the body feel cool and as cool as the natural wind.
The exhaust fan is a type of air conditioning appliance that is driven by a motor to drive the fan blades to rotate and drive the airflow to exchange indoor and outdoor air, also known as ventilation fans. The purpose of exhaust is to remove indoor dirty air, adjust temperature and humidity, and is widely used in homes and public places.
