Abstract

본 발명에 따른 공기조화기는 냉매가 다단 압축되는 제 1,2 압축기와; 제 2 압축기에서 압축된 냉매가 응축되는 응축기와; 응축기에서 응축된 냉매 중 일부가 통과하면서 냉각되는 제 1 유로와; 제 1 유로와 열교환되는 제 2 유로를 갖는 과냉 열교환기와; 과냉 열교환기에서 냉각된 냉매가 팽창되는 팽창기구와; 팽창기구에서 팽창된 냉매가 증발되고, 냉수 수요처와 수배관으로 연결되어 냉수 수요처로 냉수를 공급하는 쉘-튜브형 증발기와; 응축기에서 응축된 냉매가 상기 제 2 유로로 안내되는 제 1 바이패스 유로와; 제 1 바이패스 유로에 설치된 과냉 팽창기와; 제 1 압축기와 제 2 압축기의 사이와 상기 제 2 유로를 연결하는 제 2 바이패스 유로를 포함하여, 토출 과열도가 감소되어 과냉량이 증대되고 그로 인해 냉수 공급 효율이 증대되는 이점이 있다.
