Accurate air supply system of air conditioning unit and realizing method thereof

The invention discloses an accurate air supply system of an air conditioning unit, belonging to telecommunication machine room temperature control technologies and mainly solving the problem that the air output of the air conditioner in the prior art is free from the control of actual ambient temperature to influence the degree of temperature regulation. The accurate air supply system of the air conditioning unit mainly comprises a fan and a controller and is characterized in that the controller comprises an upper controller and a lower controller, wherein the upper controller comprises a microprocessor, as well as an input device, an output device, a temperature sensor and a control switch which are respectively connected with the microprocessor, the lower controller is connected with the output device, and the fan is connected with the lower controller. The invention also discloses a realizing method of the hardware. The accurate air supply system and the realizing method thereof are favorable for not only realizing the accurate control of the air output but also guaranteeing that telecommunication facilities always work in an environment at an optimal temperature, and have greatly improved practical values.
