冷凍水循環(huan)系統  

　　該部分由冷(leng)凍(dong)(dong)泵(beng)、室(shi)(shi)內(nei)(nei)風機(ji)及冷(leng)凍(dong)(dong)水(shui)(shui)管(guan)道等組成。從主(zhu)機(ji)蒸發器流出的低溫冷(leng)凍(dong)(dong)水(shui)(shui)由冷(leng)凍(dong)(dong)泵(beng)加(jia)壓送入冷(leng)凍(dong)(dong)水(shui)(shui)管(guan)道（出水(shui)(shui)），進入室(shi)(shi)內(nei)(nei)進行熱交(jiao)(jiao)換，帶走房(fang)間內(nei)(nei)的熱量，最后回到主(zhu)機(ji)蒸發器（回水(shui)(shui)）。室(shi)(shi)內(nei)(nei)風機(ji)用于(yu)將空(kong)(kong)氣(qi)吹過冷(leng)凍(dong)(dong)水(shui)(shui)管(guan)道，降低空(kong)(kong)氣(qi)溫度(du)，加(jia)速(su)室(shi)(shi)內(nei)(nei)熱交(jiao)(jiao)換。

　　水流(liu)方向：空調主機→冷凍水泵→室內(nei)風機→空調主機

　　冷卻水循環(huan)系統

　　該(gai)部分(fen)由(you)冷(leng)卻(que)(que)(que)泵、冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)管道、冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)塔及冷(leng)凝器(qi)等(deng)組成(cheng)。冷(leng)凍水(shui)(shui)(shui)(shui)循環(huan)系統進行(xing)室內(nei)熱交換的(de)同時(shi)，必將(jiang)帶走室內(nei)大(da)量的(de)熱能。該(gai)熱能通過(guo)主機內(nei)的(de)冷(leng)媒(mei)傳遞給冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)，使冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)溫(wen)度升(sheng)高(gao)。冷(leng)卻(que)(que)(que)泵將(jiang)升(sheng)溫(wen)后的(de)冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)壓入冷(leng)卻(que)(que)(que)水(shui)(shui)(shui)(shui)塔（出水(shui)(shui)(shui)(shui)），使之與(yu)大(da)氣進行(xing)熱交換，降低溫(wen)度后再送回(hui)主機冷(leng)凝器(qi)（回(hui)水(shui)(shui)(shui)(shui)）。

　　水流方向：空(kong)調主(zhu)機→冷卻(que)水泵(beng)→冷卻(que)水塔→空(kong)調主(zhu)機  

　　主機

　　主機(ji)(ji)部(bu)分由壓(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)、蒸(zheng)(zheng)(zheng)發器(qi)、冷(leng)(leng)(leng)凝器(qi)及(ji)冷(leng)(leng)(leng)媒（制(zhi)冷(leng)(leng)(leng)劑）等(deng)組(zu)成(cheng)，其工作(zuo)循環(huan)過(guo)程如(ru)下： 首先低(di)壓(ya)(ya)(ya)(ya)氣(qi)態冷(leng)(leng)(leng)媒被壓(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)加(jia)壓(ya)(ya)(ya)(ya)進入冷(leng)(leng)(leng)凝器(qi)并逐漸冷(leng)(leng)(leng)凝成(cheng)高壓(ya)(ya)(ya)(ya)液體。在(zai)冷(leng)(leng)(leng)凝過(guo)程中(zhong)冷(leng)(leng)(leng)媒會釋(shi)放出大(da)量(liang)熱能(neng)，這部(bu)分熱能(neng)被冷(leng)(leng)(leng)凝器(qi)中(zhong)的冷(leng)(leng)(leng)卻水吸收并送到(dao)室外的冷(leng)(leng)(leng)卻塔上，最終(zhong)釋(shi)放到(dao)大(da)氣(qi)中(zhong)去。隨后冷(leng)(leng)(leng)凝器(qi)中(zhong)的高壓(ya)(ya)(ya)(ya)液態冷(leng)(leng)(leng)媒在(zai)流經蒸(zheng)(zheng)(zheng)發器(qi)前的節(jie)流降壓(ya)(ya)(ya)(ya)裝置時(shi)(shi)，因為壓(ya)(ya)(ya)(ya)力(li)的突(tu)變(bian)而氣(qi)化(hua)，形成(cheng)氣(qi)液混合物進入蒸(zheng)(zheng)(zheng)發器(qi)。冷(leng)(leng)(leng)媒在(zai)蒸(zheng)(zheng)(zheng)發器(qi)中(zhong)不斷氣(qi)化(hua)，同(tong)時(shi)(shi)會吸收冷(leng)(leng)(leng)凍水中(zhong)的熱量(liang)使其達(da)到(dao)較低(di)溫度。最后，蒸(zheng)(zheng)(zheng)發器(qi)中(zhong)氣(qi)化(hua)后的冷(leng)(leng)(leng)媒又變(bian)成(cheng)了(le)(le)低(di)壓(ya)(ya)(ya)(ya)氣(qi)體，重新進入了(le)(le)壓(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)，如(ru)此循環(huan)往復。  

　　冷(leng)凍水(shui)系統(tong)(tong)和(he)冷(leng)卻(que)水(shui)系統(tong)(tong)是兩個獨立的(de)水(shui)循(xun)環(huan)系統(tong)(tong)，最終(zhong)目的(de)實(shi)現(xian)了將室內的(de)熱(re)量通(tong)過(guo)冷(leng)卻(que)水(shui)系統(tong)(tong)與空氣的(de)熱(re)交換。
