Webctrltm - based automatic control systems of variable air volume system of the beijing union university 的北京聯(lián)大實(shí)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(duì)變風(fēng)量系統(tǒng)的工作原理、系統(tǒng)特點(diǎn)、適用場(chǎng)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(guò)改變送風(fēng)量來(lái)滿足室內(nèi)舒適要求的系統(tǒng),所以氣流分布對(duì)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(guò)于昂貴,故國(guó)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(duì)系統(tǒng)設(shè)計(jì)中各主要方面諸如負(fù)荷計(jì)算、風(fēng)量取值、風(fēng)口選型以及系統(tǒng)在冬夏運(yùn)行調(diào)節(jié)時(shí)的風(fēng)機(jī)控制方式,系統(tǒng)運(yùn)行模式作了一定的探討并提出了自己的見(jiàn)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(diǎn),經(jīng)過(guò)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)。
