Abstract

압축-팽창 공기 조화 시스템용 고 잠열 냉각 제어 조립체는 실내 공기 증발기 코일의 빠져나가는 공기 쪽에 배치된 보조 냉각기 코일을 채택한다. 액체 라인 분기관은 응축기로부터 보조 냉각기 코일로 응축된 액체를 공급하며, TXV일 수 있는 유동 제한기는 냉매가 증발기 코일과 결합된 팽창 장치에 도달하기 전에 보조 냉각된 액체 압력을 강하시킨다. 바이패스 라인은 응축기를 팽창 장치에 연결하며, 자동 습도 조절기에 의해 작동되는 액체 라인 솔레노이드 밸브를 갖는다. 제습이 요구될 때, 솔레노이드 밸브는 폐쇄되고 냉매는 보조 냉각기 코일을 통해 유동한다. 자동 습도 조절기가 만족된 때, 솔레노이드 밸브는 개방되고 냉매 경로는 보조 냉각기 코일을 바이패스한다. 고 잠열 보조 냉각기 조립체는 특정 부지에 설치되거나 기존의 공기 조화기에 개장될 수 있다.
