再考慮室外機空氣溫度高低、室內(nèi)冷負荷大小等影響低壓壓力的因素，微調(diào)氟利昂的量和表壓力，做到準(zhǔn)確加氟。進行微調(diào)的原因是因為低壓力與室內(nèi)冷負荷成正比，即冷負荷越大，壓力越高，反之越低；加氟工藝口及附近管道，因安裝在室外，其壓力及蒸發(fā)溫度受外界氣溫影響很大，室內(nèi)熱交換器實際壓力及蒸發(fā)溫度夏天要偏高一些，冬天要偏低一些。實踐中總結(jié)的在風(fēng)扇高速風(fēng)，室內(nèi)溫度為27℃的情況下，低壓壓力數(shù)據(jù)如附表所示。（6）觀察法：將空調(diào)設(shè)置在制冷或制熱高速風(fēng)狀態(tài)下運轉(zhuǎn)，加氟量準(zhǔn)確時室內(nèi)熱交換器進、出風(fēng)口處10cm的溫差是：制冷時大于12℃，制熱時大于16℃；制冷時，室內(nèi)熱交換器全部結(jié)露、蒸發(fā)聲均勻低沉、室外截止閥處結(jié)露、夏季冷凝滴水連續(xù)不斷、室內(nèi)熱交換器與毛細管的連接處無霜有露等；制熱時，室內(nèi)熱交換器壁溫大于40℃。長寧區(qū)實驗室精密空調(diào)清洗基站精密空調(diào)專業(yè)清洗保養(yǎng)。</p><div

6、土建投資對比：氨機組結(jié)構(gòu)較大，占地面積大，除了機組外，還需要安裝高壓儲液罐和循環(huán)桶等輔機，總占地面積為氟系統(tǒng)的5倍，而氟利昂機組結(jié)構(gòu)緊湊，占地面積小，所以對安裝環(huán)境的要求也相對較低，適用范圍更廣。以上來看機房精密空調(diào)氟系統(tǒng)與氨系統(tǒng)相比無論是從哪個方面來看，優(yōu)勢更加明顯，未來，氟系統(tǒng)將逐步占領(lǐng)冷藏市場，將是行業(yè)發(fā)展的主流。什么環(huán)境下要對機房精密空調(diào)加氟安全對比：氨屬于0液體，對人體會產(chǎn)生強烈的刺激，當(dāng)空氣中的氨達到，當(dāng)濃度達到14%就可以引起燃燒，當(dāng)達到25%時就會引起，威脅到人們的生命財產(chǎn)安全；而氟利昂系統(tǒng)采用環(huán)保R22與R404A制冷劑，具有無色、無味、不可燃燒，不會的化學(xué)性質(zhì)，可應(yīng)用于各種場所當(dāng)中，安全穩(wěn)定，杜絕了的發(fā)生，有效的保證了員工與周圍民眾的生命安全。</p><p> 原因:數(shù)據(jù)中心離心機組安裝完成后,機房末端設(shè)備沒有安裝,末端冷凍水路不通,冷機無法調(diào)試;即使通過分集水器進行冷凍水旁通,也**使冷機能夠開機運行,缺少熱負荷,或者熱負荷過小,無法達到冷機下限負荷,調(diào)試工作無法進行。另一方面,由于冷機未調(diào)試,主機房服務(wù)器設(shè)備無法加電運行,相互形成一個死循環(huán);另外調(diào)試過程中,需要的假負載功率巨大,運行過程會耗費大量電能;上述因素導(dǎo)致冷機調(diào)試成為一個難題。<span style="font-size:12px;">對策:采用無負荷調(diào)試方法進行調(diào)試。數(shù)據(jù)中心為了降低能效,考慮自然冷卻,一般采用冷卻塔+板換供冷技術(shù)設(shè)計。調(diào)試時可以利用板換的換熱能力,從冷機的冷凝器獲得足夠的熱量作為冷機調(diào)試的熱負荷,也就是冷機產(chǎn)生的冷量通過板換帶走。</span>

8應(yīng)急補水問題案例:補水過慢。原因:管路發(fā)生泄漏后,缺少應(yīng)急補水措施和緊急補水口,系統(tǒng)的補水只能通過定壓或膨脹水箱處補水,由于管徑過小,難以快速恢復(fù)系統(tǒng)壓力,為了應(yīng)急,只能打開冷機冷凍水管路的排污口,布置消防水帶,消防水通過消防水帶和排污口對系統(tǒng)進行補水,才保證了機房的安全對策:設(shè)計時,數(shù)據(jù)中心水系統(tǒng)必須考慮應(yīng)急補水措施,如單獨的應(yīng)急補水泵和應(yīng)急補水口,確保管網(wǎng)發(fā)生異常情況時,可以通過應(yīng)急補水口對系統(tǒng)進行快速補水。9防凍問題案例二:冷機調(diào)試完成后,需要正式運行,但冷機總負荷偏小,導(dǎo)致冷機啟停頻繁和喘振現(xiàn)象。原因:負荷過低,導(dǎo)致冷機喘振。對策:板換作為假負載,繼續(xù)投入運行,確保冷機運行平穩(wěn),成功度過低負載時間。基站精密空調(diào)的用途。長寧區(qū)實驗室精密空調(diào)清洗</p><p

style="text-indent:25px">但是，在機房中，顯熱負荷幾乎完全由IT硬件、燈光、支持設(shè)備和供電產(chǎn)生的顯熱組成。因為幾乎沒有人，室外空氣有限，并且通常經(jīng)過防潮處理，所以，潛熱非常少。針對這種情況，空調(diào)所需的顯熱比非常高，為0.95~0.99。只有機房精密空調(diào)可以達到這種非常高的顯熱比。相對而言，舒適性空調(diào)的顯熱比通常為0.65~0.70，因此，提供的顯熱量過少，潛熱冷量過多。過多的潛熱冷量一位著將不斷地從空氣中去除水分。為了保持所需的相對濕度范圍45%~50%，將需要不斷加濕，而這肯定要消耗大量的能量。長寧區(qū)實驗室精密空調(diào)清洗</p><p
