陜西商用中央空調螺桿機--螺桿(gan)(gan)式(shi)(shi)(shi)冷(leng)(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)原(yuan)理：螺桿(gan)(gan)式(shi)(shi)(shi)冷(leng)(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)因其關鍵部件(jian)-壓(ya)(ya)(ya)(ya)縮機(ji)(ji)(ji)(ji)采用(yong)螺桿(gan)(gan)式(shi)(shi)(shi)故名螺桿(gan)(gan)式(shi)(shi)(shi)冷(leng)(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)，機(ji)(ji)(ji)(ji)組由由蒸發(fa)器出來的狀態(tai)為的氣體(ti)冷(leng)(leng)(leng)(leng)(leng)媒；經(jing)壓(ya)(ya)(ya)(ya)縮機(ji)(ji)(ji)(ji)絕熱(re)壓(ya)(ya)(ya)(ya)縮以(yi)后(hou)，變(bian)(bian)成高(gao)溫(wen)高(gao)壓(ya)(ya)(ya)(ya)狀態(tai)。被(bei)壓(ya)(ya)(ya)(ya)縮后(hou)的氣體(ti)冷(leng)(leng)(leng)(leng)(leng)媒，在冷(leng)(leng)(leng)(leng)(leng)凝(ning)器中，等壓(ya)(ya)(ya)(ya)冷(leng)(leng)(leng)(leng)(leng)卻冷(leng)(leng)(leng)(leng)(leng)凝(ning)，經(jing)冷(leng)(leng)(leng)(leng)(leng)凝(ning)后(hou)變(bian)(bian)化成液態(tai)冷(leng)(leng)(leng)(leng)(leng)媒，再經(jing)節流(liu)閥膨脹(zhang)到(dao)低壓(ya)(ya)(ya)(ya)，變(bian)(bian)成氣液混合物。其中低溫(wen)低壓(ya)(ya)(ya)(ya)下(xia)的液態(tai)冷(leng)(leng)(leng)(leng)(leng)媒，在蒸發(fa)器中吸收被(bei)冷(leng)(leng)(leng)(leng)(leng)物質的熱(re)量(liang)，重新變(bian)(bian)成氣態(tai)冷(leng)(leng)(leng)(leng)(leng)媒。

氣態冷(leng)媒經管道(dao)重(zhong)新進(jin)入壓縮機，開始新的(de)(de)循環。這(zhe)就是冷(leng)凍(dong)循環的(de)(de)四個過(guo)程，也是螺(luo)桿式冷(leng)水機的(de)(de)主要工(gong)作原理。
