【摘要】：建筑节能这个问题近几年来越来越受重视,绿色校园建设的话题也已成为当今社会的一个热点议题。目前,我国的许多大学学生宿舍并没有配备空调设备,夏季室内酷暑难耐,影响到学生们日常生活。本文以毛细管辐射空调系统为研究对象,并且选取了四座代表性城市——西安、武汉、广州和上海,探讨了采用该系统服务于这四座城市的大学生宿舍时,毛细管网结构和运行参数的合理取值。并且通过建模并利用MATLAB软件编程,核算了该系统的供冷以及供热能力,结果表明,毛细管辐射空调系统通过辐射换热与室内进行热交换,换热能力大大高于其他换热设备,系统效率非常高。其次,针对单独使用毛细管辐射空调过程中会出现的结露问题,对比了采用独立新风系统和室内除湿机两种方案的除湿效果,建议采用室内吊顶除湿机来处理室内潮湿的空气防止结露。该系统在旧建筑改造中可发挥工期短、安装简便的优势,而且使用简单。如若将吊顶除湿机系统与毛细管辐射空调系统进行双系统耦合,当毛细管辐射空调系统的室内湿度探测探头发现室内湿度过高,而存在结露风险时,系统自动开启吊顶除湿机进行除湿,这将大大提高系统的智能化程度。鉴于我国幅员辽阔的特点,选取西安建筑科技大学研究生宿舍为实例,进行软件模拟。利用ANASYS软件,对学生宿舍进行模型构建,划分网格,将毛细管辐射空调系统输入到模型中,模拟出该系统实际运行时,室内不同高度的温度云图。结果表明,毛细管辐射空调系统辐射板温度均匀,室内温度稳定,能够很好的满足人体舒适度需求。但是,由于该系统目前依靠国外技术生产,因此自身的造价较高,经济性较差。有一天能够国产化的话,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.
