- 스트로크 지령치에 따른 인가 전압에 의해, 피스톤이 상하운동으로 스트로크를 가변시켜 냉력을 조절하는 왕복동식 압축기를 채용한 냉장고에 있어서,모터에 인가되는 전류를 이전에 검출된 전류와 비교하여 TDC=0인 전류 피크치를 검출하는 제1 단계와;상기 제1 단계의 전류피크치를 기준으로 TDC=0인 최적의 운전조건을 재검출하기 위한 전류 최대값을 설정하는 제2 단계와;상기 제1 단계의 전류피크치에 해당되는 스위칭제어신호로 트라이악의 온/오프를 제어하여 왕복동식 압축부를 운전하면서 그 왕복동식 압축부에 인가되는 전류를 기설정된 전류 최대값과 비교하는 제3 단계와;상기 제3 단계의 비교결과, 인가 전류가 기설정된 전류최대값 보다 크면, 다시 TDC=0인 최적의 운전조건을 검출하는 제4 단계로 수행함을 특징으로 하는 왕복동식 압축기를 이용한 냉장고의 운전제어방법.
- 제1 항에 있어서, 인가전류가 기설정된 전류최대값 보다 작으면 현재 전류피크치에 해당되는 스위칭제어신호로 왕복동식 압축부를 운전제어하는 단계를 더 포함하는 것을 특징으로 하는 왕복동식 압축기를 이용한 냉장고의 운전제어방법.
