Webctrltm - based automatic control systems of variable air volume system of the beijing union university 的北京聯(lián)大實訓(xùn)室變風(fēng)量空調(diào)自控系統(tǒng)
Variable air volume systems have been widely used in various kinds of buildings due to their energy - savings , comfort , safety and good flexibility 變風(fēng)量系統(tǒng)因其節(jié)能、舒適、安全以及好的靈活性而被廣泛應(yīng)用于各類建筑物。
This paper gives an detailed description to various aspects of the variable air volume system , such as the working principle , peculiarities of system , and its applicable location 摘要對變風(fēng)量系統(tǒng)的工作原理、系統(tǒng)特點、適用場合均作了詳細(xì)地闡述。
Because the basic principle of variable air volume system is to meet the comfort conditions indoor by varying air flow rates , air distribution is rather important 由于變風(fēng)量系統(tǒng)是通過改變送風(fēng)量來滿足室內(nèi)舒適要求的系統(tǒng),所以氣流分布對于變風(fēng)量系統(tǒng)是相當(dāng)重要的。
As air distributor in a variable air volume system , the performance of slot diffuser is the best one , but the type of diffuser is too expensive , so at home many firms try to choose square diffuser 條縫形散流器作為變風(fēng)量系統(tǒng)的空氣分布器其性能是最好的,但這種條縫形散流器過于昂貴,故國內(nèi)許多公司選擇采用方形散流器。
And also this paper analyzes many important aspects about the design of the variable air volume system , for exam pie the calculation method of cold and volume , the choice of tuyeres , the adjustment operating mode of the fan during summer and winter and proffer form some opinions 對系統(tǒng)設(shè)計中各主要方面諸如負(fù)荷計算、風(fēng)量取值、風(fēng)口選型以及系統(tǒng)在冬夏運行調(diào)節(jié)時的風(fēng)機(jī)控制方式,系統(tǒng)運行模式作了一定的探討并提出了自己的見解。
After more than 40 years " development , variable air volume systems have been widely used in many places besides north america , japan and singapore because of their excellences and have become the most popular and energy - conserving air conditioning systems in commercial buildings Vav系統(tǒng)由于具有諸多優(yōu)點,經(jīng)過40多年的發(fā)展,在北美、日本、新加坡等地都得到了廣泛的應(yīng)用,它已經(jīng)成為目前商業(yè)建筑中最流行和最節(jié)能的空調(diào)系統(tǒng)。
