陜西中央空調--變頻多聯機系(xi)(xi)統(tong)是(shi)“變頻一(yi)拖多可(ke)變冷(leng)(leng)媒(mei)流量中(zhong)央(yang)空(kong)調系(xi)(xi)統(tong)”的簡稱(cheng)，是(shi)由一(yi)臺室外機(ji)和若干臺室內機(ji)組成的一(yi)個冷(leng)(leng)媒(mei)循(xun)環系(xi)(xi)統(tong)。是(shi)變制(zhi)冷(leng)(leng)劑(ji)(ji)流量（variedrefrigerant Volume）空(kong)調系(xi)(xi)統(tong)的一(yi)種形式，是(shi)一(yi)種制(zhi)冷(leng)(leng)劑(ji)(ji)式空(kong)調系(xi)(xi)統(tong)，它以制(zhi)冷(leng)(leng)劑(ji)(ji)為(wei)輸送介質，屬空(kong)氣—空(kong)氣熱泵系(xi)(xi)統(tong)。

該系統由(you)制(zhi)冷(leng)(leng)劑(ji)管(guan)路連接(jie)的(de)(de)室(shi)(shi)(shi)外機和(he)室(shi)(shi)(shi)內(nei)(nei)機組成(cheng)，室(shi)(shi)(shi)外機由(you)室(shi)(shi)(shi)外側換熱(re)器(qi)、壓縮(suo)機和(he)其它制(zhi)冷(leng)(leng)附件組成(cheng)；室(shi)(shi)(shi)內(nei)(nei)機由(you)風機和(he)直接(jie)蒸發器(qi)等(deng)組成(cheng)。一臺室(shi)(shi)(shi)外機通(tong)過管(guan)路能夠向若干個室(shi)(shi)(shi)內(nei)(nei)機輸(shu)送制(zhi)冷(leng)(leng)劑(ji)液體，通(tong)過控制(zhi)壓縮(suo)機的(de)(de)制(zhi)冷(leng)(leng)劑(ji)循(xun)環量和(he)進入室(shi)(shi)(shi)內(nei)(nei)各個換熱(re)器(qi)的(de)(de)制(zhi)冷(leng)(leng)劑(ji)流(liu)量，可以適時地(di)滿足室(shi)(shi)(shi)內(nei)(nei)冷(leng)(leng)熱(re)負荷要求。
