相信(xin)中央空(kong)調是今夏最(zui)火爆的(de)關鍵詞，隨著空(kong)調技術(shu)的(de)不斷發展(zhan)，中央空(kong)調是今后空(kong)調發展(zhan)的(de)一大(da)趨(qu)勢。那中央空(kong)調有什(shen)么優勢呢？廣州中央空(kong)調公司負(fu)責(ze)人給(gei)你解說一下：

中央空調系(xi)(xi)統(tong)一般主要由制冷(leng)壓(ya)縮機(ji)系(xi)(xi)統(tong)、冷(leng)媒(冷(leng)凍和冷(leng)熱)循環水系(xi)(xi)統(tong)、冷(leng)卻循環水系(xi)(xi)統(tong)、盤(pan)管風(feng)機(ji)系(xi)(xi)統(tong)、冷(leng)卻塔(ta)風(feng)機(ji)系(xi)(xi)統(tong)等組成。中央空調有很多(duo)形式，較(jiao)為(wei)常見的有：風(feng)管式機(ji)組、冷(leng)(熱)水機(ji)組、變頻一拖多(duo)機(ji)組。

中央空(kong)調(diao)制冷基(ji)本(ben)原理

液(ye)(ye)體(ti)(ti)(ti)汽(qi)(qi)(qi)化(hua)制(zhi)冷(leng)(leng)是(shi)利用液(ye)(ye)體(ti)(ti)(ti)汽(qi)(qi)(qi)化(hua)時(shi)(shi)的(de)(de)吸熱、冷(leng)(leng)凝(ning)(ning)時(shi)(shi)的(de)(de)放熱效應來實現制(zhi)冷(leng)(leng)的(de)(de)。液(ye)(ye)體(ti)(ti)(ti)汽(qi)(qi)(qi)化(hua)形成蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)。當液(ye)(ye)體(ti)(ti)(ti)（制(zhi)冷(leng)(leng)工質(zhi)）處在(zai)密閉的(de)(de)容(rong)器(qi)中(zhong)(zhong)時(shi)(shi)，此容(rong)器(qi)中(zhong)(zhong)除了液(ye)(ye)體(ti)(ti)(ti)及液(ye)(ye)體(ti)(ti)(ti)本身(shen)所產(chan)生的(de)(de)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)外，不存在(zai)其(qi)他(ta)任何氣體(ti)(ti)(ti)，液(ye)(ye)體(ti)(ti)(ti)和蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)將(jiang)在(zai)某一(yi)(yi)(yi)壓(ya)力(li)(li)下達到平(ping)衡，此時(shi)(shi)的(de)(de)汽(qi)(qi)(qi)體(ti)(ti)(ti)稱(cheng)為飽(bao)和蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)，壓(ya)力(li)(li)稱(cheng)為飽(bao)和壓(ya)力(li)(li)，溫(wen)(wen)度稱(cheng)為飽(bao)和溫(wen)(wen)度。平(ping)衡時(shi)(shi)液(ye)(ye)體(ti)(ti)(ti)不再汽(qi)(qi)(qi)化(hua)，這(zhe)時(shi)(shi)如果將(jiang)一(yi)(yi)(yi)部分蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)從容(rong)器(qi)中(zhong)(zhong)抽走，液(ye)(ye)體(ti)(ti)(ti)必然要繼續汽(qi)(qi)(qi)化(hua)產(chan)生一(yi)(yi)(yi)部分蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)來維持這(zhe)一(yi)(yi)(yi)平(ping)衡。 液(ye)(ye)體(ti)(ti)(ti)汽(qi)(qi)(qi)化(hua)時(shi)(shi)要吸收熱量(liang)，此熱量(liang)稱(cheng)為汽(qi)(qi)(qi)化(hua)潛熱。汽(qi)(qi)(qi)化(hua)潛熱來自被冷(leng)(leng)卻對(dui)象，使被冷(leng)(leng)卻對(dui)象變(bian)冷(leng)(leng)。為了使這(zhe)一(yi)(yi)(yi)過(guo)程連續進(jin)行，就(jiu)必須從容(rong)器(qi)中(zhong)(zhong)不斷地抽走蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)，并(bing)使其(qi)凝(ning)(ning)結成液(ye)(ye)體(ti)(ti)(ti)后再回到容(rong)器(qi)中(zhong)(zhong)去。從容(rong)器(qi)中(zhong)(zhong)抽出的(de)(de)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)如直接冷(leng)(leng)凝(ning)(ning)成蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)，則所需(xu)冷(leng)(leng)卻介(jie)質(zhi)的(de)(de)溫(wen)(wen)度比液(ye)(ye)體(ti)(ti)(ti)的(de)(de)蒸(zheng)(zheng)(zheng)發溫(wen)(wen)度還要低，我們希望蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)的(de)(de)冷(leng)(leng)凝(ning)(ning)是(shi)在(zai)常(chang)溫(wen)(wen)下進(jin)行，因此需(xu)要將(jiang)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)的(de)(de)壓(ya)力(li)(li)提高(gao)到常(chang)溫(wen)(wen)下的(de)(de)飽(bao)和壓(ya)力(li)(li)。
