Cooling by ventilation:

1. The temperature of the place that needs to be ventilated is higher than the outdoor due to the heat sources such as buildings, machinery and equipment, and human body being irradiated by sunlight.

Exhaust fan can quickly discharge the indoor hot air, so that the room temperature is equal to the outside temperature, and the temperature in the workshop will not rise.

2. The air flow takes away the heat of the human body, and the air flow accelerates the evaporation of sweat and absorbs the heat of the human body, so that the human body feels cool, as cool as the natural wind.

3. Exhaust fan only has the function of ventilation and cooling, and has no cooling function. Coolness is the feeling of the human body. It is ignorant to say how much temperature the Exhaust fan can reduce.

4. Used in conjunction with the water curtain, the temperature in the workshop can be controlled within 28 degrees Celsius in the hottest time of summer. However, the coolness of the human body can be compared with that of the air conditioner. People who face the water curtain for a long time will feel cold and can’t stand it.

The principle of negative pressure ventilation cooling system

one. What is a negative pressure ventilation cooling system? Negative pressure ventilation cooling system = negative pressure fan + water curtain wall

two. Is it the principle of negative pressure cooling?

It is an artificial reproduction of the natural physical process of “water evaporation and heat absorption”. A fan is installed in the closed workshop, and a wet curtain is installed on the other side. The fan draws away the high-temperature air in the workshop, so that a negative pressure is formed in the workshop. When it is cooled down, it exchanges heat with the air in the workshop, thereby reducing the temperature in the workshop.

three. What is the working principle of the Exhaust fan?

Exhaust fan is designed using the principle of air convection and negative pressure ventilation. The Fengsuda negative pressure fan is installed in a place with poor ventilation. During normal operation, the negative pressure is used to remove the stagnant hot air, odor and black smoke in the workshop. It can quickly discharge the outdoor air in the shortest time, and at the same time send outdoor fresh air into the room, and quickly pull the air indoors, so as to achieve the purpose of ventilation and cooling to improve the high temperature and stuffy environment of the workshop.

Four. Wet curtain cooling principle

The wet curtain is a special paper honeycomb structure material. Its working principle is the natural physical phenomenon of “water evaporation absorbs heat”, that is, water flows from top to bottom under the action of gravity, and the corrugated fibers of the wet curtain A water film is formed on the surface. When the flowing air passes through the wet curtain, the water in the water film will absorb the heat in the air and evaporate, taking away a large amount of latent heat, reducing the temperature of the air passing through the wet curtain, thereby achieving the purpose of cooling.

Compared with traditional air conditioners and fans, the ventilation and cooling system is environmentally friendly, energy-saving, and has good effects. Moreover, the negative pressure ventilation and cooling system has a long warranty period and saves maintenance and maintenance. There are workshops and farms that need ventilation. If you want to cool down, you can contact Fengsuda. We provide free planning and design solutions.

It is the responsibility of every business person to create a working environment that is ventilated, comfortable, healthy, environmentally friendly and energy-saving.
