陜西商用中央空調螺桿機--螺(luo)桿(gan)式(shi)(shi)冷(leng)(leng)水(shui)機原理：螺(luo)桿(gan)式(shi)(shi)冷(leng)(leng)水(shui)機因其(qi)關鍵部件-壓(ya)(ya)(ya)縮機采用螺(luo)桿(gan)式(shi)(shi)故(gu)名(ming)螺(luo)桿(gan)式(shi)(shi)冷(leng)(leng)水(shui)機，機組由由蒸(zheng)(zheng)發器出來(lai)的(de)(de)狀態(tai)為的(de)(de)氣(qi)體冷(leng)(leng)媒；經(jing)壓(ya)(ya)(ya)縮機絕(jue)熱(re)壓(ya)(ya)(ya)縮以后(hou)(hou)，變成(cheng)(cheng)高溫(wen)高壓(ya)(ya)(ya)狀態(tai)。被壓(ya)(ya)(ya)縮后(hou)(hou)的(de)(de)氣(qi)體冷(leng)(leng)媒，在(zai)冷(leng)(leng)凝(ning)器中(zhong)，等壓(ya)(ya)(ya)冷(leng)(leng)卻冷(leng)(leng)凝(ning)，經(jing)冷(leng)(leng)凝(ning)后(hou)(hou)變化成(cheng)(cheng)液態(tai)冷(leng)(leng)媒，再經(jing)節流閥膨脹到低(di)壓(ya)(ya)(ya)，變成(cheng)(cheng)氣(qi)液混合物(wu)。其(qi)中(zhong)低(di)溫(wen)低(di)壓(ya)(ya)(ya)下的(de)(de)液態(tai)冷(leng)(leng)媒，在(zai)蒸(zheng)(zheng)發器中(zhong)吸收被冷(leng)(leng)物(wu)質(zhi)的(de)(de)熱(re)量，重新變成(cheng)(cheng)氣(qi)態(tai)冷(leng)(leng)媒。

氣態冷媒經管道重(zhong)新進入壓縮機，開始新的循環(huan)(huan)。這就是(shi)冷凍循環(huan)(huan)的四個過程，也是(shi)螺桿式(shi)冷水機的主要工(gong)作(zuo)原(yuan)理。
