陜西商用中央空調螺桿機--螺桿(gan)(gan)式冷(leng)(leng)(leng)(leng)(leng)水(shui)(shui)機(ji)(ji)原理：螺桿(gan)(gan)式冷(leng)(leng)(leng)(leng)(leng)水(shui)(shui)機(ji)(ji)因其關鍵部件-壓(ya)縮(suo)機(ji)(ji)采用(yong)螺桿(gan)(gan)式故名螺桿(gan)(gan)式冷(leng)(leng)(leng)(leng)(leng)水(shui)(shui)機(ji)(ji)，機(ji)(ji)組由由蒸發(fa)器出來的狀(zhuang)態為的氣體冷(leng)(leng)(leng)(leng)(leng)媒；經壓(ya)縮(suo)機(ji)(ji)絕熱壓(ya)縮(suo)以后(hou)，變(bian)(bian)成高溫高壓(ya)狀(zhuang)態。被壓(ya)縮(suo)后(hou)的氣體冷(leng)(leng)(leng)(leng)(leng)媒，在冷(leng)(leng)(leng)(leng)(leng)凝器中(zhong)，等壓(ya)冷(leng)(leng)(leng)(leng)(leng)卻(que)冷(leng)(leng)(leng)(leng)(leng)凝，經冷(leng)(leng)(leng)(leng)(leng)凝后(hou)變(bian)(bian)化(hua)成液(ye)態冷(leng)(leng)(leng)(leng)(leng)媒，再經節流閥膨脹到低壓(ya)，變(bian)(bian)成氣液(ye)混(hun)合物。其中(zhong)低溫低壓(ya)下的液(ye)態冷(leng)(leng)(leng)(leng)(leng)媒，在蒸發(fa)器中(zhong)吸收被冷(leng)(leng)(leng)(leng)(leng)物質的熱量，重(zhong)新變(bian)(bian)成氣態冷(leng)(leng)(leng)(leng)(leng)媒。

氣態冷(leng)媒經管(guan)道(dao)重新進入壓縮(suo)機，開始新的循環(huan)。這就(jiu)是(shi)冷(leng)凍循環(huan)的四個過程(cheng)，也是(shi)螺桿式冷(leng)水機的主要(yao)工作原理。
