陜西中央空調--變頻多聯機系(xi)(xi)統(tong)(tong)(tong)是(shi)“變頻一(yi)(yi)拖多可變冷(leng)媒(mei)流量(liang)中央空(kong)調(diao)(diao)系(xi)(xi)統(tong)(tong)(tong)”的(de)(de)簡稱，是(shi)由一(yi)(yi)臺室外機和若干臺室內(nei)機組(zu)成的(de)(de)一(yi)(yi)個冷(leng)媒(mei)循環(huan)系(xi)(xi)統(tong)(tong)(tong)。是(shi)變制(zhi)冷(leng)劑(ji)流量(liang)（variedrefrigerant Volume）空(kong)調(diao)(diao)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)一(yi)(yi)種形式(shi)，是(shi)一(yi)(yi)種制(zhi)冷(leng)劑(ji)式(shi)空(kong)調(diao)(diao)系(xi)(xi)統(tong)(tong)(tong)，它以(yi)制(zhi)冷(leng)劑(ji)為輸送介質，屬空(kong)氣—空(kong)氣熱(re)泵系(xi)(xi)統(tong)(tong)(tong)。

該系統(tong)由制(zhi)(zhi)(zhi)冷(leng)劑管路(lu)(lu)連接的(de)(de)室(shi)(shi)(shi)外機(ji)和室(shi)(shi)(shi)內(nei)(nei)機(ji)組成，室(shi)(shi)(shi)外機(ji)由室(shi)(shi)(shi)外側換熱(re)器(qi)、壓縮機(ji)和其(qi)它制(zhi)(zhi)(zhi)冷(leng)附件(jian)組成；室(shi)(shi)(shi)內(nei)(nei)機(ji)由風機(ji)和直接蒸(zheng)發器(qi)等組成。一臺室(shi)(shi)(shi)外機(ji)通(tong)過(guo)管路(lu)(lu)能夠向若(ruo)干(gan)個(ge)室(shi)(shi)(shi)內(nei)(nei)機(ji)輸送制(zhi)(zhi)(zhi)冷(leng)劑液體(ti)，通(tong)過(guo)控制(zhi)(zhi)(zhi)壓縮機(ji)的(de)(de)制(zhi)(zhi)(zhi)冷(leng)劑循環(huan)量(liang)和進入室(shi)(shi)(shi)內(nei)(nei)各個(ge)換熱(re)器(qi)的(de)(de)制(zhi)(zhi)(zhi)冷(leng)劑流量(liang)，可以適時地(di)滿足(zu)室(shi)(shi)(shi)內(nei)(nei)冷(leng)熱(re)負荷(he)要求。
