【摘要】：建筑節(jié)能這個(gè)問(wèn)題近幾年來(lái)越來(lái)越受重視,綠色校園建設(shè)的話題也已成為當(dāng)今社會(huì)的一個(gè)熱點(diǎn)議題。目前,我國(guó)的許多大學(xué)學(xué)生宿舍并沒(méi)有配備空調(diào)設(shè)備,夏季室內(nèi)酷暑難耐,影響到學(xué)生們?nèi)粘Ｉ�。本文以毛�?xì)管輻射空調(diào)系統(tǒng)為研究對(duì)象,并且選取了四座代表性城市——西安、武漢、廣州和上海,探討了采用該系統(tǒng)服務(wù)于這四座城市的大學(xué)生宿舍時(shí),毛細(xì)管網(wǎng)結(jié)構(gòu)和運(yùn)行參數(shù)的合理取值。并且通過(guò)建模并利用MATLAB軟件編程,核算了該系統(tǒng)的供冷以及供熱能力,結(jié)果表明,毛細(xì)管輻射空調(diào)系統(tǒng)通過(guò)輻射換熱與室內(nèi)進(jìn)行熱交換,換熱能力大大高于其他換熱設(shè)備,系統(tǒng)效率非常高。其次,針對(duì)單獨(dú)使用毛細(xì)管輻射空調(diào)過(guò)程中會(huì)出現(xiàn)的結(jié)露問(wèn)題,對(duì)比了采用獨(dú)立新風(fēng)系統(tǒng)和室內(nèi)除濕機(jī)兩種方案的除濕效果,建議采用室內(nèi)吊頂除濕機(jī)來(lái)處理室內(nèi)潮濕的空氣防止結(jié)露。該系統(tǒng)在舊建筑改造中可發(fā)揮工期短、安裝簡(jiǎn)便的優(yōu)勢(shì),而且使用簡(jiǎn)單。如若將吊頂除濕機(jī)系統(tǒng)與毛細(xì)管輻射空調(diào)系統(tǒng)進(jìn)行雙系統(tǒng)耦合,當(dāng)毛細(xì)管輻射空調(diào)系統(tǒng)的室內(nèi)濕度探測(cè)探頭發(fā)現(xiàn)室內(nèi)濕度過(guò)高,而存在結(jié)露風(fēng)險(xiǎn)時(shí),系統(tǒng)自動(dòng)開(kāi)啟吊頂除濕機(jī)進(jìn)行除濕,這將大大提高系統(tǒng)的智能化程度。鑒于我國(guó)幅員遼闊的特點(diǎn),選取西安建筑科技大學(xué)研究生宿舍為實(shí)例,進(jìn)行軟件模擬。利用ANASYS軟件,對(duì)學(xué)生宿舍進(jìn)行模型構(gòu)建,劃分網(wǎng)格,將毛細(xì)管輻射空調(diào)系統(tǒng)輸入到模型中,模擬出該系統(tǒng)實(shí)際運(yùn)行時(shí),室內(nèi)不同高度的溫度云圖。結(jié)果表明,毛細(xì)管輻射空調(diào)系統(tǒng)輻射板溫度均勻,室內(nèi)溫度穩(wěn)定,能夠很好的滿足人體舒適度需求。但是,由于該系統(tǒng)目前依靠國(guó)外技術(shù)生產(chǎn),因此自身的造價(jià)較高,經(jīng)濟(jì)性較差。有一天能夠國(guó)產(chǎn)化的話,前途不可限量。
[Abstract]:In recent years, more and more attention has been paid to the issue of building energy conservation, and the topic of green campus construction has become a hot topic in our society. At present, many college student dormitories in China are not equipped with air conditioning equipment, and the summer indoor heat is difficult to endure, which affects the daily life of students. In this paper, the capillary radiation air conditioning system is taken as the research object, and four representative cities, Xi'an, Wuhan, Guangzhou and Shanghai, are selected to discuss the use of the system to serve the dormitory of college students in these four cities. The reasonable value of the structure and operation parameters of capillary net. Through modeling and programming with MATLAB software, the cooling and heating capacity of the system is calculated. The results show that the heat transfer capacity of the capillary radiation air conditioning system is much higher than that of other heat transfer equipment through radiation heat transfer and indoor heat exchange. The system is very efficient. Secondly, the dehumidification effect of independent fresh air system and indoor dehumidifier is compared in view of the condensation problem in the process of using capillary radiation air conditioning alone. It is recommended that indoor ceiling dehumidifier be used to deal with indoor moist air to prevent dedew. The system can give full play to the advantages of short construction period, simple installation and simple use in the old building reconstruction. If the ceiling dehumidifier system is coupled with the capillary radiation air conditioning system, when the indoor humidity detection probe of the capillary radiation air conditioning system finds that the indoor humidity is too high and there is a risk of condensation, The system automatically opens the ceiling dehumidifier for dehumidification, which will greatly improve the intelligence of the system. In view of the vast territory of our country, this paper takes the graduate dormitory of Xi'an University of Architecture and Science and Technology as an example to simulate the software. By using Anasys software, the model of student dormitory was built, and the capillary radiation air conditioning system was input into the model. The temperature cloud map of different heights in the room was simulated when the system was in operation. The results show that the radiation plate temperature of capillary radiation air conditioning system is uniform and the indoor temperature is stable. However, because the system depends on foreign technology production, its own cost is high and its economy is poor. One day, if you can make it locally, the future will be limitless.
