Design for air conditioning evaporator superheat based on direct adaptive fuzzy controller

Abstract

The working principle and the best overheating conditions of evaporator in air conditioning system is analyzed. Using direct adaptive fuzzy controller to control superheat degree at the outlet of the evaporator. And compare to control effects based on traditional PID controller and fuzzy controller in different working conditions by simulation with MATLAB. The results show that direct adaptive fuzzy controller can control evaporator superheat better and improve the energy efficiency of air conditioning when working conditions change.
