陜西商用中央空調螺桿機--螺(luo)桿式(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)(ji)原理：螺(luo)桿式(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)(ji)因其關鍵(jian)部(bu)件-壓(ya)(ya)縮機(ji)(ji)(ji)采用螺(luo)桿式(shi)故名螺(luo)桿式(shi)冷(leng)(leng)(leng)(leng)水機(ji)(ji)(ji)，機(ji)(ji)(ji)組由由蒸發(fa)器(qi)出來的(de)(de)狀態(tai)為(wei)的(de)(de)氣體冷(leng)(leng)(leng)(leng)媒；經(jing)壓(ya)(ya)縮機(ji)(ji)(ji)絕熱(re)壓(ya)(ya)縮以后(hou)，變(bian)(bian)(bian)成高溫高壓(ya)(ya)狀態(tai)。被壓(ya)(ya)縮后(hou)的(de)(de)氣體冷(leng)(leng)(leng)(leng)媒，在(zai)冷(leng)(leng)(leng)(leng)凝(ning)器(qi)中(zhong)，等(deng)壓(ya)(ya)冷(leng)(leng)(leng)(leng)卻冷(leng)(leng)(leng)(leng)凝(ning)，經(jing)冷(leng)(leng)(leng)(leng)凝(ning)后(hou)變(bian)(bian)(bian)化成液態(tai)冷(leng)(leng)(leng)(leng)媒，再經(jing)節(jie)流閥(fa)膨脹(zhang)到低(di)壓(ya)(ya)，變(bian)(bian)(bian)成氣液混(hun)合物(wu)。其中(zhong)低(di)溫低(di)壓(ya)(ya)下的(de)(de)液態(tai)冷(leng)(leng)(leng)(leng)媒，在(zai)蒸發(fa)器(qi)中(zhong)吸(xi)收被冷(leng)(leng)(leng)(leng)物(wu)質的(de)(de)熱(re)量，重新變(bian)(bian)(bian)成氣態(tai)冷(leng)(leng)(leng)(leng)媒。

氣態冷媒經管(guan)道重新進入(ru)壓縮(suo)機，開始新的循(xun)環。這就是冷凍循(xun)環的四個過程，也是螺桿式冷水機的主要(yao)工作原理。
