空調(diào)制熱費(fèi)電嗎-空調(diào)制冷工作原理
一般空調(diào)是由四大件組成:壓縮機(jī)、冷凝器、膨脹閥和蒸發(fā)器,根據(jù)控制或是使用需要中間可以選擇安裝壓力控制器、溫度控制器、干燥過濾器等輔助器件,但四大件是必不可少的。工作時(shí)氣態(tài)制冷劑通過壓縮機(jī)被壓縮成高溫高壓的氣體后,進(jìn)入冷凝器,冷凝器相當(dāng)于一個(gè)換熱設(shè)備,將高溫高壓的氣態(tài)制冷劑換熱成低溫低壓的液態(tài)制冷劑。液態(tài)制冷劑再通過膨脹閥,所謂膨脹閥就是一個(gè)節(jié)流裝置,因流出膨脹閥的制冷劑受到遏制,因此出來后制冷劑壓力降低,溫度繼續(xù)下降,成為氣液兩相,再進(jìn)入蒸發(fā)器,此時(shí)的制冷劑再蒸發(fā)器中進(jìn)行換熱氣化,成為高溫低壓的氣態(tài)制冷劑回到壓縮機(jī)繼續(xù)循環(huán)。
