陜西中央空調--變頻多聯機系(xi)(xi)統(tong)是(shi)“變(bian)頻一拖(tuo)多可變(bian)冷(leng)(leng)媒(mei)流量中央空(kong)(kong)(kong)調系(xi)(xi)統(tong)”的簡稱，是(shi)由一臺室(shi)外(wai)機和若干臺室(shi)內機組成的一個冷(leng)(leng)媒(mei)循環系(xi)(xi)統(tong)。是(shi)變(bian)制(zhi)(zhi)冷(leng)(leng)劑(ji)流量（variedrefrigerant Volume）空(kong)(kong)(kong)調系(xi)(xi)統(tong)的一種形式，是(shi)一種制(zhi)(zhi)冷(leng)(leng)劑(ji)式空(kong)(kong)(kong)調系(xi)(xi)統(tong)，它以制(zhi)(zhi)冷(leng)(leng)劑(ji)為輸送介質，屬空(kong)(kong)(kong)氣(qi)—空(kong)(kong)(kong)氣(qi)熱泵系(xi)(xi)統(tong)。

該系統由制(zhi)(zhi)(zhi)冷(leng)劑(ji)管(guan)路連接的(de)室(shi)外機(ji)和(he)室(shi)內(nei)(nei)(nei)機(ji)組成，室(shi)外機(ji)由室(shi)外側換熱(re)器、壓(ya)縮(suo)機(ji)和(he)其它制(zhi)(zhi)(zhi)冷(leng)附件組成；室(shi)內(nei)(nei)(nei)機(ji)由風機(ji)和(he)直接蒸(zheng)發器等組成。一臺室(shi)外機(ji)通過(guo)管(guan)路能夠向若干(gan)個室(shi)內(nei)(nei)(nei)機(ji)輸送制(zhi)(zhi)(zhi)冷(leng)劑(ji)液(ye)體，通過(guo)控(kong)制(zhi)(zhi)(zhi)壓(ya)縮(suo)機(ji)的(de)制(zhi)(zhi)(zhi)冷(leng)劑(ji)循(xun)環量和(he)進(jin)入室(shi)內(nei)(nei)(nei)各個換熱(re)器的(de)制(zhi)(zhi)(zhi)冷(leng)劑(ji)流量，可以適時地滿(man)足室(shi)內(nei)(nei)(nei)冷(leng)熱(re)負荷要(yao)求。
