   相信很多消費(fei)者(zhe)和小編一(yi)樣都不(bu)知道空(kong)(kong)(kong)(kong)調(diao)需(xu)要抽真空(kong)(kong)(kong)(kong)吧，說(shuo)(shuo)到真空(kong)(kong)(kong)(kong)，真空(kong)(kong)(kong)(kong)是(shi)(shi)什么呢？實際上真空(kong)(kong)(kong)(kong)是(shi)(shi)一(yi)種(zhong)不(bu)存在任何(he)物質的(de)空(kong)(kong)(kong)(kong)間(jian)狀(zhuang)態，是(shi)(shi)一(yi)種(zhong)物理現象。對于空(kong)(kong)(kong)(kong)調(diao)來說(shuo)(shuo)，抽真空(kong)(kong)(kong)(kong)是(shi)(shi)空(kong)(kong)(kong)(kong)調(diao)生產(chan)、安裝和維修過程中，充注(zhu)制冷劑(ji)前的(de)一(yi)個必不(bu)可少的(de)重要工(gong)序。
