Abstract
Description
Claims (3)
- 스트로크 지령치에 따른 스트로크 전압에 의해, 피스톤이 상하운동으로 스트로크를 가변시켜 냉력을 조절하는 리니어 컴프레샤와; 스트로크전압에 의해 스트로크를 증가시킴에 따라, 상기 리니어 컴프레샤에 인가되는 전류를 검출하는 전류 검출부와; 상기 전류검출부의 전류를 입력받아 이를 한 주기 동안 적분하여 그에 따른 일연산신호를 출력하는 일연산부와; 실험에 의해, 스위칭제어신호의 듀티비의 가변에 따른 다수의 일연산신호와 그 다수의 일연산신호에 일대일 대응되는 흡입/토출 압차가 각기 기저장되는 흡입/토출압차저장부와; 상기 일연산부의 일연산신호를 입력받아 그 일연산신호에 따른 흡입/토출압차를 상기 흡입/토출압차저장부로부터 읽어들여 이를 부하로 디스플레이시키고, 아울러 상기 일연산부의 일연산신호를 이전 일연산신호와 비교하여 그에 따른 스위칭제어신호를 출력하는 마이크로컴퓨터와; 상기 마이크로컴퓨터의 스위칭제어신호에 따라, 교류전원을 트라이악으로 단속시켜 상기 리니어컴프레샤에 스트로크전압을 인가하는 전기회로부를 포함하여 구성한 것을 특징으로 하는 리니어 컴프레샤의 부하검출장치.
- 제1 항에 있어서, 마이크로컴퓨터는 일연산부의 일연산신호가 순차적으로 저장되는 메모리를 포함하는 것을 특징으로 하는 리니어 컴프레샤의 부하검출장치.
- 제1 항 또는 제2 항에 있어서, 마이크로컴퓨터는 현재 일연산신호를 이전 일연산신호와 비교하여 그 차이가 소정값 이하이면 스위칭제어신호의 듀티비를 점차 증가시켜 출력하다가, 현재 일연산신호와 이전 일연산신호의 차이가 소정값 이상이 되면 현 시점의 스위칭제어신호를 유지시켜 출력하는 것을 특징으로 하는 리니어 컴프레샤의 부하검출장치.
