MDD-093B-F-020-N2L-110GA0變頻器的發(fā)展及作用發(fā)布時間:12-11-15 來源: 深圳市粵鴻遠(yuǎn)科技有限公司業(yè)務(wù)部 點擊量:47445 更多
變頻空調(diào)、變頻電冰箱、變頻微波爐、變頻洗衣機(jī)、變頻電磁爐……這些都是家電企業(yè)打出的綠色環(huán)保牌。而與其他綠色環(huán)保概念有所不同的是,變頻技術(shù)不僅帶有公益性質(zhì),更主要的是能夠?qū)崒嵲谠诮o消費者帶來實惠。
MDD-093B-F-020-N2L-110GA0變頻技術(shù)的核心部件是變頻器,變頻器全稱交流變頻調(diào)速器,用于交流電機(jī),在調(diào)整輸出頻率的同時按比例調(diào)整輸出電壓,從而改變電機(jī)轉(zhuǎn)速,以達(dá)到交流電機(jī)調(diào)速的目的。變頻器是電力電子技術(shù)、微電子技術(shù)、控制技術(shù)相結(jié)合的綜合性高技術(shù)產(chǎn)品,被稱為“現(xiàn)代工業(yè)維生素”。
MDD-093B-F-020-N2L-110GA0變頻器于20世紀(jì)60年代問世,到20世紀(jì)80年代在主要工業(yè)化國家已經(jīng)得到廣泛使用,特別是在日本,變頻技術(shù)在家用電器中的應(yīng)用更為普遍,幫助其確立了電器大國的地位。
MDD-093B-F-020-N2L-110GA0變頻的第一功效即是節(jié)能,電機(jī)系統(tǒng)在設(shè)計過程中都留有一定的余量,變頻器通過降低電機(jī)轉(zhuǎn)速減少輸出功耗,實現(xiàn)“按需供能”。變頻器用于風(fēng)機(jī)、泵類等,可達(dá)到50%的節(jié)能率;用于其他工藝要求調(diào)速的負(fù)載,也可獲得10%至40%的節(jié)能效果。
MDD-093B-F-020-N2L-110GA0以冰箱為例,我國的電源電壓為220伏、50赫茲,在這種條件下工作的空調(diào)是定頻空調(diào)。由于供電頻率不能改變,定頻空調(diào)的壓縮機(jī)轉(zhuǎn)速基本不變,所以它不能大幅度的調(diào)節(jié)制冷量,而是通過頻繁開啟關(guān)閉壓縮機(jī)的方式來調(diào)節(jié)房間溫度高低。而與之相比,變頻空調(diào)通過改變電機(jī)轉(zhuǎn)速“按需供能”,這樣它的壓縮機(jī)就不會頻繁開啟,會使壓縮機(jī)保持穩(wěn)定的工作狀態(tài),可以使空調(diào)整體達(dá)到節(jié)能30%以上的效果,同時可以減少噪音(就是所謂的靜音化)、延長空調(diào)使用壽命。
