0px;">　　水泵及管道的挑選，關系到日后運用的費用，所以應該請有經驗的規劃師來挑選，空調的質量怎么樣，主機的質量只占40%，結尾及配套規劃，占60%。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　空調泵的運用是為了管道中水能更好的循環，所以挑選空調循環水泵流量有必要大，揚程高度和管路丟失有必要核算準確。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　最好依據水力核算最晦氣環路來，這個也是我們專業大力提倡的;可是一般情況在沒有特殊要求的情況下都是預算的多，因為水泵揚程的核算公式原本就是預算，所以還不如徹底預算</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　預算方法1：</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　暖通<a target="_self" style="text-decoration-line: none; color: rgb(51, 51, 51); outline: none;"><strong>空調泵</strong></a>的挑選：一般選用比轉數ns在130～150的離心式清水泵，空調泵的流量應為冷水機組額定流量的1.1～1.2倍(單臺取1.1，兩臺并聯取1.2。按預算可大致取每100米管長的沿程丟失為5mH2O，水泵揚程(mH2O)：</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　Hmax=△P1+△P2+0.05L (1+K)</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　△P1為冷水機組蒸發器的水壓降。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　△P2為該環中并聯的各占空調未端設備的水壓丟失最大的一臺的水壓降。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　L為該最晦氣環路的管長</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　K為最晦氣環路中部分阻力當量長度總和和與直管總長的比值，當最晦氣環路較長時K值取0.2～　0.3，最晦氣環路較短時K值取0.4～0.6</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　預算方法2：</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　這兒所談的是閉式空調冷水體系的阻力組成，因為這種體系是量常用的體系。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　1.冷水機組阻力：由機組制造廠供給，一般為60~100kPa。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　2.管路阻力：包括磨擦阻力、部分阻力，其間單位長度的磨擦阻力即比摩組取決于技術經濟比較。若取值大則管徑小，初出資省，但水泵運行能耗大;若取值小則反之。目前規劃中冷水管路的比摩組宜操控在150~200Pa/m范圍內，管徑較大時，取值可小些。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　3.空調未端設備阻力：結尾設備的類型有風機盤管機組，組合式空調器等。它們的阻力是依據規劃提出的空氣進、出空調盤管的參數、冷量、水溫差等由制造廠通過盤管配置核算后供給的，許多額定工況值在產品樣本上能查到。此項阻力一般在20~50kPa范圍內。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　4.調節閥的阻力：空調房間總是要求操控室溫的，通過在空調結尾設備的水路上設置電動二通調節閥是完成室溫操控的一種手法。二通閥的規格由閥門全開時的流轉能力與允許壓力降來挑選的。如果此允許壓力降取值大，則閥門的操控功能好;若取值小，則操控功能差。閥門全開時的壓力降占該支路總壓力降的百分數被稱為閥權度。水體系規劃時要求閥權度S>0.3，于是，二通調節閥的允許壓力降一般不小于40kPa。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　依據以上所述，能夠粗略估量出一幢約100m高的高層建筑空調水體系的壓力丟失，也即循環水泵所需的揚程：</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　1.冷水機組阻力：取80 kPa(8m水柱);</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　2.管路阻力：取冷凍機房內的除污器、集水器、分水器及管路等的阻力為50 kPa;取輸配側管路長度300m與比摩阻200 Pa/m，則磨擦阻力為300*200=60000 Pa=60 kPa;如考慮輸配側的部分阻力為磨擦阻力的50%，則部分阻力為60 kPa*0.5=30 kPa;體系管路的總阻力為50 kPa+60 kPa+30 kPa=140 kPa(14m水柱);</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　3.空調結尾設備阻力：組合式空調器的阻力一般比風機盤管阻力大，故取前者的阻力為45 kPa(4.5水柱);</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　4.二通調節閥的阻力：取40 kPa(0.4水柱)。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　5.于是，水體系的各部分阻力之和為：80 kPa+140kPa+45 kPa+40 kPa=305 kPa(30.5m水柱)</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　6.水泵揚程：取10%的安全系數，則揚程H=30.5m*1.1=33.55m。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　依據以上預算結果，能夠根本掌握類同規模建筑物的空調水體系的壓力丟失值范圍，特別應防止因未通過核算，過于保守，而將體系壓力丟失估量過大，水泵揚程選得過大，導致能量糟蹋。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;">　　空調泵要依據不同機型和機型大小而定!</p></div><p><br/></p> <div class="pageJump"> <p style="float:left;">上一個：<a href="/show-900.html">不銹鋼泵的應用</a></p> <p style="float:right;">下一個：<a
