如果不對水質進行處理將嚴重損壞制冷設備，大幅度降低熱交換效率，造成能源的浪費。因此，對系統(tǒng)水進行緩蝕、阻垢、殺菌滅藻處理是十分重要的。風冷系統(tǒng)缺點：風冷制冷機組單位制冷量的耗電量略高于水冷機組，但風冷機組的年度綜合費用與水冷機組基本持平稍低。技術經(jīng)濟分析結果表明，對于中、小型制冷機組配置風冷冷凝器是合理的。制冷機組年運行時間越長，采用風冷冷凝方式越有利。三、兩種機組的技術經(jīng)濟比較例1：20HP比澤爾中高溫壓縮機，在蒸發(fā)溫度0度冷凝溫度50度時為，功率，而水冷在相同工況時冷量為，功率為。從冷量和用電量來說略優(yōu)于風冷機組，居家機電安裝哪家公司好。但水冷水泵功率冷卻塔風扇功率還未加入計算，居家機電安裝哪家公司好。例2：以某型號水冷制冷機組和主機、蒸發(fā)器相同的風冷制冷機組進行比較。壓縮機的年運行時間為1000小時至3000小時，冷卻塔和水泵的年運行時間相應為1400小時至4200小時。風冷制冷機組的運行費用：風冷制冷機組年耗電費用=（壓縮機耗電量+風機耗電量）×運行時間/年×電價，居家機電安裝哪家公司好。水冷制冷機組的運行費用：水冷制冷機組年水費=（總循環(huán)水×換水次數(shù)+補水量×總循環(huán)水量×運行時間/年）×水價。水冷制冷機組年耗電費用=。電子廠空調通風末端保養(yǎng)工程。居家機電安裝哪家公司好</p><div

經(jīng)常有人問到風冷，水冷哪個好的問題，在此我們共同探討一下。結合實際經(jīng)驗做如下論述?？紤]到大型制冷機組的風冷冷凝器數(shù)量偏多，通常很難布置，另一方面，過小的水冷制冷機組也不利于使用，因而對中等的風冷機組和與之相同的水冷制冷機組進行比較。一、結構比較風冷式機組采用空氣冷卻方式（風扇降溫）；水冷機組采用冷卻水冷卻方式，水泵加冷卻塔及循環(huán)管路對機組循環(huán)降溫。從水冷的安裝方式來看，又可以分為內置水冷和外置水冷兩種。對于內置水冷而言，主要由散熱器、水管、水泵、足夠的水源組成，這就注定了大部分水冷散熱系統(tǒng)“體積”較大，而且要求機箱內部空間足夠寬余。因此風冷機組只需風冷冷凝器即風扇即可。而水冷冷水機組需配冷卻塔，水泵、循環(huán)管路。從結構上水冷要復雜于風冷。風冷制冷機組適用于所處地域水源緊張的地區(qū)，對年運行時數(shù)越長的制冷系統(tǒng)采用風冷制冷機組越有利。風冷制冷機組的年度綜合費用低于水冷系統(tǒng)，但水冷系統(tǒng)若管理得法，補水量控制在3％以下，則水冷機組的年度費用要低于風冷系統(tǒng)。二、水冷與風冷系統(tǒng)優(yōu)缺點：水冷系統(tǒng)缺點：對于開式冷卻循環(huán)水系統(tǒng)，由于冷卻水吸收熱量后，與空氣接觸，CO2逸入空氣中，水中溶解氧和濁度增加。居家機電安裝哪家公司好醫(yī)院通風維護工程，。</p><div

三、離心式冷水機組優(yōu)點：1.葉輪轉速高，輸氣量大，單機容量大；2.易損件少，工作可靠，結構緊湊，運轉平穩(wěn)，振動小，噪聲低；3.單位制冷量重量指標小；4.制冷劑中不混有潤滑油，蒸發(fā)器和冷凝器的傳熱性能好；，理論值可達；6.調節(jié)方便，在10%~100%內可無級調節(jié)。缺點：1.單級壓縮機在低負荷時會出現(xiàn)“喘振”現(xiàn)象，在滿負荷運轉平穩(wěn)；2.對材料強度，加工精度和制造質量要求嚴格；3.當運行工況偏離設計工況時效率下降較快，制冷量隨蒸發(fā)溫度降低而減少幅度比活塞式快；4.離心負壓系統(tǒng)，外氣易侵入，有產(chǎn)生化學變化腐蝕管路的危險。四、模塊化冷水機組優(yōu)點：1.系活塞式和螺桿式的改良型，它是由多個冷水單元組合而成；2.機組體積小，重量輕，高度低，占地??；3.安裝簡單，無需預留安裝孔洞，現(xiàn)場組合方便，特別適用于改造工程。缺點：1.價格較貴；2.模塊臺數(shù)一般不宜超過8臺。五、水源熱泵機組優(yōu)點：1.節(jié)約能源，在冬季運行時，可回收熱量；2.取源于自然；3.能效比相對較高；4.安裝便利，維修費低；5.應用靈活，調節(jié)方便。缺點：1.在過度季節(jié)不能比較大限度利用新風；2.機組噪聲較大。六、溴化鋰吸收式冷水機組（蒸汽，熱水和直燃型）優(yōu)點：1.運動部件少，故障率低，運動平穩(wěn)。</p><p>

應關閉一次回風閥，全開排風閥和新風閥。組合式空調機組能量回收段供雙風機系統(tǒng)中作交叉分風混合和排風能量回收用。本段箱體內設有一次回風閥，頂部為能量回收器，它是一種利用排風的冷（熱）來間接冷卻（加熱）新風，新風經(jīng)過板式能量回收裝置，可回收排風顯熱能量的60%左右。同時，排風和新風不直接接觸，特別適用于排除室內有害氣體的直流空調系統(tǒng)的能量回收。作直流系統(tǒng)使用時，應關閉一次回風閥門,有劇毒氣體場所應單獨設排風系統(tǒng)，不宜使用該段。組合式空調機組中間段（檢修段）本段起過渡段的連接和機組內部檢修照明用。在過濾段前，表冷段、加熱段、消聲段前后均須設中間段.組合式空調機組二次回風段連接二次回風管用的中間段，頂部可設調節(jié)閥門，配有手動、電動或氣動調節(jié)機構，由用戶任選，此段也可各并于送風機段中。組合式空調機組表冷段表冷器采用四、六、八排管的銅管串鋁箔的結構，鋁箔為雙翻邊波紋邊形式，大彎管熱交換器減少60%的焊接彎頭，提高了熱交換功率，先進的機械漲管形式保證了熱交換器的接觸性能，該熱交換器分固定式和旋轉式兩種，用戶可根據(jù)需要任選一種，熱媒采用蒸汽或熱水。居家機電安裝哪家公司好</p><p
