【摘要】：能源问题日益严重,为了开发利用可再生能源,达到节能减排、可持续发展的目的,本文研究了太阳能低温地板辐射采暖系统在华北地区的可行性。依据太阳辐射相关理论,基于目前与实测值比较吻合的Hottel Model模型,运用VB编写程序,计算了全国主要城市全年晴天水平面和任意角度倾斜面上的太阳辐射量、日出时间、日落时间、峰值、全天累计辐射量以及太阳能集热器的最佳倾斜角度。该程序可计算本地区太阳辐射量,并能为相近地区太阳辐射量计算提供参考。能满足一般太阳能工程和科学研究的需要。本文利用DeST-h模拟技术对天津市一栋独体别墅进行了动态热负荷模拟。研究了间歇性供暖的形式不同室外温度下系统供暖的间歇时间及供暖时间表。利用CFD技术模拟研究了不同地面材料、不同供水水温对地板采暖地板温度分布影响。对太阳能集热器、储热水箱、辅助热源等进行了合理选择与优化设计,设计了一套太阳能低温地板辐射采暖系统。本文介绍了相变蓄热技术应用于太阳能供热系统的发展,设计了一套相变蓄热式太阳能低温地板辐射采暖系统。包括蓄热器的设计和相变蓄热介质的选型。模拟了以相变蓄热地板作为热源为地板采暖提供热量的地板温度分布。本文研究了太阳能低温地板辐射采暖系统的环境效益与经济效益,得到了太阳能地板采暖系统在运行期间内有着良好的环境效益和经济效益。虽然初投资较高,但运行费用低廉,并且长期运行该系统可大大减少二氧化碳排量,有利于缓解全球变暖,同时也减少了酸性气体和悬浮颗粒物的排放量。
[Abstract]:The energy problem is becoming more and more serious. In order to develop and utilize renewable energy to achieve the purpose of energy saving and emission reduction and sustainable development, the feasibility of solar low temperature floor radiation heating system in North China is studied in this paper.Based on the theory of solar radiation, based on the Hottel Model model, which is in good agreement with the measured values, and using VB to compile a program, the amount of solar radiation and the time of sunrise on the sunny water plane and any angle inclined plane of major cities in China are calculated.Sunset time, peak, all-day accumulated radiation and optimum tilt angle of solar collector.The program can calculate the solar radiation in this area and provide reference for the calculation of solar radiation in similar areas.To meet the general needs of solar engineering and scientific research.In this paper, the dynamic thermal load simulation of a single-body villa in Tianjin was carried out by using DeST-h simulation technology.The intermittent time and schedule of system heating under different outdoor temperatures were studied.The effects of different surface materials and water temperature on floor temperature distribution of floor heating were simulated by CFD technology.The solar collector, hot water storage box and auxiliary heat source are selected and optimized, and a solar low temperature floor radiant heating system is designed.In this paper, the application of phase change heat storage technology in solar heating system is introduced, and a set of phase change regenerative solar floor radiant heating system is designed.It includes the design of accumulator and the selection of phase change storage medium.The temperature distribution of the floor with phase change heat storage floor as the heat source for floor heating was simulated.In this paper, the environmental and economic benefits of solar low temperature floor radiation heating system are studied, and the results show that the solar panel heating system has good environmental and economic benefits during the operation period.Although the initial investment is high, the operation cost is low, and the long-term operation of the system can greatly reduce carbon dioxide emissions, contribute to the mitigation of global warming, but also reduce the emissions of acid gases and suspended particulates.
