AC SYSTEM WITH PROPORTIONAL CONTROLLED HYDRAULIC FAN

摘要

A system and method for improving the operation of a cooling system and AC system for an engine, without sacrificing engine performance is disclosed. The system includes a cooling module positioned within an engine compartment of the vehicle, a cooling fan mounted in front of the cooling module, and a control strategy for controlling operation of the cooling fan based on engine conditions. The system includes incorporating at least one sensor, include a pressure sensor installed within the high pressure side of the AC system. The method includes providing an AC system having a high pressure side and a low pressure side, providing at least one sensor on the high pressure side for producing an electrical signal in response to an operating condition, determining which sensor has a highest electrical signal value for controlling the speed of the fan.
