中央空調(diào)系統(tǒng)水泵變頻節(jié)能改造方案

1、中央空調(diào)系統(tǒng)水泵變頻節(jié)能改造方案一、概述中央空調(diào)系統(tǒng)在現(xiàn)代企業(yè)及生活環(huán)境改善方面極為普遍，而且某此生活環(huán)境或生產(chǎn)工序中是屬必須的，即所謂人造環(huán)境，不僅是溫度的要求，還有濕度、潔凈度等。至所以要中央空調(diào)系統(tǒng)，目的是提高產(chǎn)品質(zhì)量， 提高人的舒適度，集中供冷供熱效率高，便管理，節(jié)省投資等原因，為此幾乎企業(yè)、高層商廈、商務(wù)大樓、會(huì)場(chǎng)、 劇場(chǎng)、辦公室、圖書館、賓館、商場(chǎng)、超市、酒店、娛樂場(chǎng)、體育館等中大型建筑上都采用中央空調(diào)的，它是現(xiàn)代 大型建筑物不可缺少的配套設(shè)施之一，電能的消耗非常之大，是用電大戶，幾乎占了用電量50%Z上，日常開支費(fèi)用很大。由于中央空調(diào)系統(tǒng)都是按最大負(fù)載并增加一定余量設(shè)計(jì)，而實(shí)際上

2、在一年中，滿負(fù)載下運(yùn)行最多只有十多天，甚至十多個(gè)小時(shí)，幾乎絕大部分時(shí)間負(fù)載都在70姒下運(yùn)行。通常中央空調(diào)系統(tǒng)中冷凍主機(jī)的負(fù)荷能隨季節(jié)氣溫變化自動(dòng)調(diào)節(jié)負(fù)載，而與冷凍主機(jī)相匹配的冷凍泵、冷卻泵卻不能自動(dòng)調(diào)節(jié)負(fù)載，幾乎長(zhǎng)期在100%ft載下運(yùn)行，造成了能量的極大浪費(fèi)，也惡化了中央空調(diào)的運(yùn)行環(huán)境和運(yùn)行質(zhì)量。隨著變頻技術(shù)的日益成熟，利用變頻器、PLG數(shù)模轉(zhuǎn)換模塊、溫度傳感器、溫度模塊等器件的有機(jī)結(jié)合，構(gòu)成溫差閉環(huán)自動(dòng)控制系統(tǒng)，自動(dòng)調(diào)節(jié)水泵的輸出流量；采用變頻調(diào)速技術(shù)不僅能使商場(chǎng)室溫維持在所期望的狀態(tài)，讓人感到舒適滿意，可使整個(gè)系統(tǒng)工作狀態(tài)平緩穩(wěn)定，更重要的是其節(jié)能效果高達(dá)30%Z上，能帶來很好outci

7、ty ofthe obl em.T o a dhere t o andfurtherimpr ovethe的經(jīng)濟(jì)效益。二、水泵節(jié)能改造的必要性中央空調(diào)是大廈里的耗電大戶，每年的電費(fèi)中空調(diào)耗電占60% 左右，因此中央空調(diào)的節(jié)能改造顯得尤為重要。由于設(shè)計(jì)時(shí)，中央空調(diào)系統(tǒng)必須按天氣最熱、負(fù)荷最大時(shí)設(shè)計(jì)，并且留10-20% 設(shè)計(jì)余量，然而實(shí)際上絕大部分時(shí)間空調(diào)是不會(huì)運(yùn)行在滿負(fù)荷狀態(tài)下，存在較大的富余，所以節(jié)能的潛力就較大，其中，冷凍主機(jī)可以根據(jù)負(fù)載變化隨之加載或減載，冷凍水泵和冷卻水泵卻不能隨負(fù)載變化作出相應(yīng)調(diào)節(jié)，存在很大的浪費(fèi)。水泵系統(tǒng)的流量與壓差是靠閥門和旁通調(diào)節(jié)來完成，因此，不可避免地存在較大截

8、流損失和大流量、高壓力、低溫差的現(xiàn)象，不僅大量浪費(fèi)電能，而且還造成中央空調(diào)最末端達(dá)不到合理效果的情況。為了解決這些問題需使水泵隨著負(fù)載的變化調(diào)節(jié)水流量并關(guān)閉旁通。再因水泵采用的是Y- 起動(dòng)方式，電機(jī)的起動(dòng)電流均為其額定電流的34倍，一臺(tái)90KW勺電動(dòng)機(jī)具起動(dòng)電流將達(dá)到500A ，在如此大的電流沖擊下，接觸器、電機(jī)的使用壽命大大下降，同時(shí)，起動(dòng)時(shí)的機(jī)械沖擊和停泵時(shí)水垂現(xiàn)象，容易對(duì)機(jī)械散件、軸承、閥門、管道等造成破壞，從而增加維修工作量和備品、備件費(fèi)用。采用變頻器控制能根據(jù)冷凍水泵和冷卻水泵負(fù)載變化隨之調(diào)整水泵電機(jī)的轉(zhuǎn)速，在滿足中央空調(diào)系統(tǒng)正常工作的情況下使冷凍水泵和冷卻水泵作出相應(yīng)調(diào)節(jié)，以達(dá)到節(jié)

9、能目的。水泵電機(jī)轉(zhuǎn)速下降，電機(jī)從電網(wǎng)吸收的電能就會(huì)大大減少。其減少的功耗 P=P0 1-(N1/N0)3 (1 )式減少的流量 Q=Q0 1-(N1/N0) ( 2 )式其中 N1 為改變后的轉(zhuǎn)速，N0 為電機(jī)原來的轉(zhuǎn)速，P0 為原電機(jī)轉(zhuǎn)速下的電機(jī)消耗功率，Q0 為原電機(jī)轉(zhuǎn)速下eelings survey, by l ooking uppublicsentime ntsto findproblems.

20、由(2 )式4 Q=Q01-(N1/N0) =100 * 1-(90/100)=10 可得出流量改變了 10 個(gè)單位，但功耗由(1 )式4 P=P01-(N1/N0)3=100 1-(90/100)3 =27.1 可以得出，功率將減少27.1 個(gè)單位，即比原來減少27.1% 。再因變頻器是軟啟動(dòng)方式，采用變頻器控制電機(jī)后，電機(jī)在起動(dòng)時(shí)及運(yùn)轉(zhuǎn)過程中均無沖擊電流，而沖擊電流是影響接觸器、電機(jī)使用壽命最主要、最直接的因素，同時(shí)采用變頻器控制電機(jī)后還可避免水垂現(xiàn)象，因此可大大延長(zhǎng)電機(jī)、接觸器及機(jī)械散件、軸承、閥門、管道的使用壽命。、中央空調(diào)系統(tǒng)構(gòu)成及工作原理圖一所示:eelings survey, b
