본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 방법을 실시하는 1 실시예의 계통도.1 is a schematic diagram of one embodiment for practicing the method of the present invention.

제2도는 (a), (b)는 본 발명의 방법의 실시예의 설명도이다.2 (a) and 2 (b) are explanatory diagrams of embodiments of the method of the present invention.

Claims (1)

냉동설비의 증발기(5)의 입구측에 마련한 전개 전폐 작동형의 자동 팽창 밸브(8)의 개폐시간의 비율을, 증발기 출구의 냉매체 가스의 과열도가 소정의 설정치인 때에 소정의 비율로 되도록 설정하고, 상기 냉매체 가스의 과열도가 상기 설정치 보다도 높아짐에 따라 상기 자동 팽창 밸브(8)의 개방시간의 비율을 점차 크게 되도록 제어하고, 또한 상기 냉매체 가스의 과열도가 상기 설정치보다도 낮아짐에 따라 상기 자동 팽창 밸브(8)의 개방시간의 비율을 점차 작아지도록 제어하는 것을 특징으로 하는 냉매체의 액체 공급 제어방법.The ratio of the opening / closing time of the expansion / closing operation type automatic expansion valve 8 provided at the inlet side of the evaporator 5 of the refrigerating facility is set to be a predetermined ratio when the superheat degree of the refrigerant gas at the outlet of the evaporator is a predetermined set value. When the superheat degree of the refrigerant body gas is higher than the set value, the ratio of the opening time of the automatic expansion valve 8 is gradually increased, and the superheat degree of the refrigerant body gas is lower than the set value. Accordingly, the ratio of the opening time of the automatic expansion valve (8) is controlled to be gradually reduced. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
