制冷劑循環系統:

蒸(zheng)發器中的液態制冷(leng)(leng)(leng)劑(ji)(ji)吸(xi)收(shou)并利用水的熱(re)(re)量，開始蒸(zheng)發，最終(zhong)造成(cheng)(cheng)制冷(leng)(leng)(leng)劑(ji)(ji)與水之(zhi)間存(cun)在(zai)一定的溫(wen)差。液態制冷(leng)(leng)(leng)劑(ji)(ji)被壓(ya)(ya)縮(suo)機(ji)吸(xi)收(shou)后(hou)，也完全蒸(zheng)發成(cheng)(cheng)氣態進(jin)入壓(ya)(ya)縮(suo)(壓(ya)(ya)力(li)和溫(wen)度上升)。氣態制冷(leng)(leng)(leng)劑(ji)(ji)通過(guo)冷(leng)(leng)(leng)凝(ning)器(空氣/水冷(leng)(leng)(leng)卻)被吸(xi)入，以收(shou)集熱(re)(re)量并冷(leng)(leng)(leng)凝(ning)成(cheng)(cheng)液體。制冷(leng)(leng)(leng)劑(ji)(ji)經膨脹閥(或毛細管)節流后(hou)，低溫(wen)低壓(ya)(ya)進(jin)入蒸(zheng)發器，完成(cheng)(cheng)制冷(leng)(leng)(leng)劑(ji)(ji)循(xun)環(huan)過(guo)程。

水循環系統:

水(shui)泵(beng)負責(ze)將水(shui)從水(shui)箱(xiang)抽到(dao)用(yong)戶需要(yao)冷(leng)卻的設備。冷(leng)凍的水(shui)帶走熱量后(hou)，溫度(du)上(shang)升(sheng)，然(ran)后(hou)回(hui)到(dao)冰柜(ju)。
