陜西商用中央空調螺桿機--螺桿(gan)(gan)式(shi)(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)原理：螺桿(gan)(gan)式(shi)(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)因其關鍵(jian)部(bu)件(jian)-壓(ya)(ya)縮(suo)機(ji)(ji)采(cai)用(yong)螺桿(gan)(gan)式(shi)(shi)故名(ming)螺桿(gan)(gan)式(shi)(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)，機(ji)(ji)組由由蒸發器(qi)出(chu)來(lai)的(de)狀態(tai)為的(de)氣(qi)體冷(leng)(leng)(leng)(leng)媒；經壓(ya)(ya)縮(suo)機(ji)(ji)絕熱壓(ya)(ya)縮(suo)以(yi)后，變(bian)成(cheng)(cheng)(cheng)高溫高壓(ya)(ya)狀態(tai)。被壓(ya)(ya)縮(suo)后的(de)氣(qi)體冷(leng)(leng)(leng)(leng)媒，在(zai)(zai)冷(leng)(leng)(leng)(leng)凝(ning)器(qi)中，等壓(ya)(ya)冷(leng)(leng)(leng)(leng)卻冷(leng)(leng)(leng)(leng)凝(ning)，經冷(leng)(leng)(leng)(leng)凝(ning)后變(bian)化(hua)成(cheng)(cheng)(cheng)液態(tai)冷(leng)(leng)(leng)(leng)媒，再經節流閥膨脹到低壓(ya)(ya)，變(bian)成(cheng)(cheng)(cheng)氣(qi)液混(hun)合物。其中低溫低壓(ya)(ya)下(xia)的(de)液態(tai)冷(leng)(leng)(leng)(leng)媒，在(zai)(zai)蒸發器(qi)中吸收被冷(leng)(leng)(leng)(leng)物質的(de)熱量，重新變(bian)成(cheng)(cheng)(cheng)氣(qi)態(tai)冷(leng)(leng)(leng)(leng)媒。

氣態(tai)冷(leng)(leng)媒(mei)經管道(dao)重新進入(ru)壓(ya)縮機(ji)，開始新的(de)循(xun)環。這(zhe)就是冷(leng)(leng)凍循(xun)環的(de)四個過程，也是螺桿式冷(leng)(leng)水機(ji)的(de)主要工作原(yuan)理。
