1．冷(熱)水機組的基本工作過程是：室外的制冷機組對冷(熱)媒水進行制冷降溫(或加熱升溫)，然后由水泵將降溫后的冷媒(熱)水輸送到安裝在室內的風機盤管機組中，由風機盤管機組采取就地回風的方式與室內空氣進行熱交換實現對室內空氣處理的目的。2．風管(道)式機組的基本工作過程是：供冷時，室外推薦防火閥的制冷機組吸收來自室內機組的制冷劑蒸氣經壓縮、冷凝后向各室內機組輸送液體制冷劑。供熱時，室外的制冷機組吸收來自冷凝器的制冷劑蒸氣經壓縮后向各室內機組輸送汽體制冷劑，室內機組通過布置在天花板上的回風口將空氣吸入，防火閥批發進(jin)行熱交換后(hou)送入安裝在室內(nei)(nei)各房間天花板中的風管(道(dao))內(nei)(nei)，并通(tong)過出風口上(shang)(shang)的散流(liu)器向(xiang)室內(nei)(nei)各房間輸送空氣(qi)。在風管(道(dao))上(shang)(shang)設計有新風門(men)和(he)排風門(men)，可以按一定比(bi)例置換空氣(qi)，以保證(zheng)室內(nei)(nei)空氣(qi)的質量(liang)。
