描述

變頻空調(diào)是相對普通空調(diào)來講的，變頻空調(diào)是在普通空調(diào)的基礎(chǔ)上選用了變頻專用壓縮機，增加了變頻控制系統(tǒng)。它的基本結(jié)構(gòu)和制冷原理和普通空調(diào)完全相同。變頻空調(diào)的主機是自動進(jìn)行無級變速的，它可以根據(jù)房間情況自動提供所需的冷（熱）量；當(dāng)室內(nèi)溫度達(dá)到期望值后，空凋主機則以能夠準(zhǔn)確保持這一溫度的恒定速度運轉(zhuǎn)，實現(xiàn)“不停機運轉(zhuǎn)”，從而保證環(huán)境溫度的穩(wěn)定。那么既然“不停機運轉(zhuǎn)”為什么還能省電呢？道理就是內(nèi)裝了變頻器，即隨時調(diào)節(jié)空調(diào)機心臟——壓縮機的運轉(zhuǎn)速度，從而做到合理使用能源；由于它的壓縮機不會頻繁開啟（壓縮機每次啟動是最費電的），會使壓縮機保持穩(wěn)定的工作狀態(tài)，這可以使空調(diào)整體達(dá)到節(jié)能30%以上的效果。
