簡要介紹了冷水機(jī)組的主要組成和外圍設(shè)備。

方法/步驟

第1步??????compressor, expansion valve (aka throttle), heat exchanger (condenser, evaporator and economizer)冷水機(jī)三大組成部分：壓縮機(jī)、膨脹閥（又稱節(jié)流閥）、熱交換器（又稱換熱器，包括冷凝器、蒸發(fā)器、經(jīng)濟(jì)器）第2步??????cooling tower冷卻塔（從用戶那出來的水經(jīng)過冷卻塔冷卻重新進(jìn)入熱交換器）hx types: coil heat exchanger and plate heat exchanger. heat recovery heat exchanger has plate heat exchanger and shell & tube heat exchanger, etc.換熱器類型有板式和盤管式。余熱回收換熱器分為板式和殼管式等。第3步??????heat pump chiller has a four-way valve for cooling and heating熱泵機(jī)組均有四通閥，可制冷和制熱
