Cooling fan curve and working point
the curve of the PQ curve refers to the air pressure fan air volume, the design of the system cooling ability and is directly related to the curve, as the system resistance is different, the fan working point along the PQ curve movement, low resistance system fan air volume is larger, the system cooling ability, high resistance of system air volume is small, as far as possible when the cooling effect is not ideal design system to reduce the resistance and maximize the air volume, under normal circumstances, the system design of the fan working point 1/2 - design in the air About two-thirds of system can be designed for high resistance in the air - by one-third 1/2. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
