style="text-indent:25px">分為雙螺桿和單螺桿兩種。除了大金和麥克維爾外，沌口復式樓美的螺桿式中央空調施工，其他廠家生產的產品都采用雙螺桿壓縮機，雙螺桿機組的市場占有率為95%，為主流技術。2）.壓縮機形式：目前風冷螺桿機組所采用的壓縮機分為：半封閉、全封閉兩種，以開利、特靈為**采用的半封閉式壓縮機，頓漢布什采用的是封閉式壓縮機，由此可見封閉式壓縮機是主流產品。對于外購壓縮機這些二、三線品牌產家，由于壓縮機的知識產權受制于人，都或多或少存在著一些問題，由于國外名義制冷量與國內不盡相同，造成生產出來的機組與主要**部件無法匹配，因此建議采用能自己生產壓縮機的廠家的產品。3）.調節(jié)方式：為了節(jié)能省電，各家中央空調廠家所采用的機組調節(jié)各有不同，主要分有：滑閥無級調節(jié)、柱塞式調節(jié)、有檔調節(jié)三種形式，機組可根據(jù)負荷自動調節(jié)輸入、出功率?；y無級調節(jié)通常在15%-***間調節(jié)，機組可很好的與冷熱負荷相匹配，運行效率高；柱塞式調節(jié)其實也就是有階調節(jié)的一種技術升級，沌口復式樓美的螺桿式中央空調施工，調節(jié)階差較大，從技術層面上講，就是用小電機來實現(xiàn)能效比提高，比如小馬拉大車，極易造成壓縮機燒毀。有檔調節(jié)技術0-25-50-75-***的技術，沌口復式樓美的螺桿式中央空調施工，已不適應現(xiàn)有市場發(fā)展的需要。由此可見滑閥無級調節(jié)是主流調節(jié)方式。</p><div

二、螺桿式壓縮機的齒形和內外壓力1、齒形轉子的扭曲螺旋齒面稱為型面．垂直于轉子軸線的平面與型面的交線稱為轉子型線。轉子的典型型線有三種：對稱圓弧型線；單邊修正不對稱擺線——圓弧型線；雙邊修正不對稱擺線——包絡圓弧型線。不對稱型線，由于內泄漏的減少，比對稱圓弧型線的功率消耗低10％左右，同時噪聲較低。目前新設計的螺桿式壓縮機大多采用不對稱型線，只在某些特殊場合下，沿用對稱孤型線。2、螺桿式壓縮機的內外壓力在螺桿式壓縮機的轉子每個運動周期內，某個工作容積中的氣體因容積縮小而被壓縮并達到一定的壓力，在這個工作容積與排氣孔口連通之前(包括連通瞬時)，此容積內的氣體壓力Pi稱為壓縮終了壓力。內壓縮終丁壓力與進氣壓力之比，稱為內壓縮比。而排氣骨內的氣體壓力(背壓力)Pd稱為外壓力或背壓力，它與進氣壓力的比值稱為外壓縮比。進、排氣孔口的位置和形狀決定了內壓縮比。運行工況或工藝流程中所要求的進、排氣壓力，決定了外壓縮比．與一般活塞式壓縮機不同，螺桿式壓縮機的內、外壓縮比彼此可以不相等。當內、外壓力不相等時．將引起附加能量的損失，同時伴隨著強烈的周期性排氣噪音。三、螺桿式壓縮機主要特點就壓縮氣體的原理而言。</p><div
