Abstract
Description
또한, 상기 제2설정시간(t2) 경과 후, 상기 배관결빙 실내기의 냉매배관의 온도와 제2설정온도(T2)를 비교하는 단계를 더 포함하는 것을 특징으로 한다.
또한, 상기 배관결빙 실내기의 냉매배관의 온도가 제2설정온도(T2) 이상인 경우, 상기 실내기의 송풍팬의 RPM을 모두 정상으로 복원시키는 단계를 더 포함하는 것을 특징으로 한다.
또한, 상기 배관결빙 실내기의 냉매배관의 온도가 제2설정온도(T2) 미만인 경우, 상기 협조 단계로 리턴되는 단계를 더 포함하는 것을 특징으로 한다.
또한, 상기 제2설정온도(T2)는 상기 제1설정온도(T1) 보다 더 작게 설정하는 것을 특징으로 한다.
