陜西中央空調--變頻多聯機系(xi)統(tong)是(shi)(shi)“變頻一拖(tuo)多(duo)可變冷媒流(liu)量(liang)中央空(kong)(kong)調系(xi)統(tong)”的(de)簡(jian)稱(cheng)，是(shi)(shi)由(you)一臺室(shi)外機(ji)和若干臺室(shi)內機(ji)組成的(de)一個冷媒循(xun)環系(xi)統(tong)。是(shi)(shi)變制冷劑流(liu)量(liang)（variedrefrigerant Volume）空(kong)(kong)調系(xi)統(tong)的(de)一種(zhong)形式(shi)，是(shi)(shi)一種(zhong)制冷劑式(shi)空(kong)(kong)調系(xi)統(tong)，它(ta)以(yi)制冷劑為輸送(song)介質，屬空(kong)(kong)氣—空(kong)(kong)氣熱泵系(xi)統(tong)。

該系(xi)統(tong)由制(zhi)(zhi)冷(leng)劑管(guan)路連接的室(shi)(shi)(shi)外(wai)(wai)機(ji)(ji)(ji)和室(shi)(shi)(shi)內(nei)機(ji)(ji)(ji)組(zu)成，室(shi)(shi)(shi)外(wai)(wai)機(ji)(ji)(ji)由室(shi)(shi)(shi)外(wai)(wai)側換(huan)熱器、壓(ya)縮(suo)機(ji)(ji)(ji)和其它(ta)制(zhi)(zhi)冷(leng)附件組(zu)成；室(shi)(shi)(shi)內(nei)機(ji)(ji)(ji)由風機(ji)(ji)(ji)和直接蒸(zheng)發器等組(zu)成。一(yi)臺室(shi)(shi)(shi)外(wai)(wai)機(ji)(ji)(ji)通過(guo)管(guan)路能夠向若干(gan)個室(shi)(shi)(shi)內(nei)機(ji)(ji)(ji)輸送制(zhi)(zhi)冷(leng)劑液(ye)體，通過(guo)控制(zhi)(zhi)壓(ya)縮(suo)機(ji)(ji)(ji)的制(zhi)(zhi)冷(leng)劑循環量和進入室(shi)(shi)(shi)內(nei)各個換(huan)熱器的制(zhi)(zhi)冷(leng)劑流量，可(ke)以適(shi)時地滿足室(shi)(shi)(shi)內(nei)冷(leng)熱負荷要求。
