Abstract

본 발명은 증발기의 과열도 제어시 보다 신속하고 정확하게 과열도를 제어하도록 한 에어콘의 증발기 과열도 제어방법에 관한 것이다.The present invention relates to a method for controlling the evaporator superheat degree of the air conditioner to control the superheat degree more quickly and accurately during the superheat degree control of the evaporator.

이러한 본 발명은 기동 초기 200sec동안은 초기 기동시에 초점을 맞추어 Kp, Ti, Td값을 설정하고, 200sec 이후에는 정상상태에 초점을 맞추어, Kp, Ti, Td값을 설정하여 전자팽창밸브의 개도를 조절하므로써 과열도 제어가 신속해지고 아울러 정확성있게 제어가 가능하게 되는 것이다.The present invention sets the Kp, Ti, and Td values by focusing at the initial startup during the initial 200 sec., And by setting the Kp, Ti, and Td values by focusing on the steady state after 200 sec. By adjusting, the superheat control can be quickly and precisely controlled.
