1380*1380*400mm Drop Hammer Exhaust Fan Hot Dip Galvanized Sheet Greenhouse Cooling System

1. Description of greenhouse cooling system

The negative pressure fan uses the cooling principle of air convection and negative pressure ventilation. It is a kind of natural inhalation of fresh air from the opposite door or window of the installation site, and quickly forcibly discharges the hot indoor air to the outside. The machine that can be improved, the cooling and ventilation effect can reach 90%-97%.

Ventilation and cooling: Due to the heat sources such as buildings, machinery and equipment, and the human body, the temperature of the places requiring ventilation is higher than that of the outdoors. The negative pressure 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.
The air flow takes away the body heat, and the air flow accelerates the evaporation of sweat and absorbs the body heat, so that the body feels cool, as cool as the natural wind.
The negative pressure 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 negative pressure fan can reduce.
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 is comparable to that of an air conditioner. People who face the water curtain for a long time will feel cold and can't stand it.
