For some large industrial companies, internal cooling The large amount and complicated temperature field distribution are difficult to meet the cooling requirements of some working areas only by strengthening natural ventilation. In order to achieve the cooling and the use of ventilation, the traditional mechanical refrigeration method has the disadvantages of large energy consumption and poor sanitary condition. Therefore, it is proposed to use the cooling fan to reduce the temperature in such areas, which can achieve better cooling effect, and can also humidify, filter and purify the air.

In the process of producing large space industrial plants and high temperature workshops with sensible heat dissipation Waste heat, such as electronic packaging workshops, fuel injection workshops, textile workshops, injection molding plants, supermarkets, canteens, etc., due to their high calorific value, sporadic dust, large smell or often produce some toxic and harmful gases in the production process. It only uses ventilation and cooling measures such as skylights, ventilation fans, gas buildings and exhaust hoods, which are far from meeting the process requirements. The use of a cooling fan can reduce the temperature, remove dust, disperse odor, enhance ventilation and ventilation. Compared with the traditional mechanical refrigeration air conditioner, the overall investment of the equipment is small, the operating cost is low, and the economic benefit is large.

Applicability analysis of cooling fans

cooling fan cooling capacity In moderate humidity areas and high humidity areas, the outdoor air condition is limited, and after the cooling fan is running, the indoor humidity often reaches 80% 2002 , the cooling fan has been widely used in large space industrial plants in Guangdong. When used as a ventilation and cooling device, the indoor environment is significantly improved, which proves that the cooling fan can be used as an energy-saving ventilation and cooling device.

cooling fan in high temperature workshop When the industrial plant is used, the gates and windows of the factory are all open, and the fresh air system is adopted to keep the positive pressure in the factory. The outdoor fresh air continuously removes the dirty and polluted gas in the room, improves the indoor sanitary condition, and at the same time reduces the indoor environment. temperature. Therefore, the cooling fan has been applied to large space industrial plants, high temperature workshops and other places where process waste heat is generated, and ventilation and cooling have broad application prospects.
