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.
