针对平板型太阳能集热器与建筑墙体一体化结构,在贴合式和分离式2种结合方式下,以上海地区典型气象年的典型气象日作为外扰参数,使用状态空间模型对二者的传热特性进行了研究。研究结果表明:2种形式的一体化结构的集热器以及单一集热器的出口温度和有效得热量相互差别均很小。三者出口温度最大差值为0.15℃。夏季时,分离式和贴合式一体化结构全天有效得热量分别占单一集热器的99.89%和97.22%,贴合式一体化结构集热器出口温度和有效得热量都比分离式低。而冬季则相反,且该比例为99.26%和106.65%。夏季时,分离式和贴合式一体化结构通过围护结构的传热量分别占单一墙体的90.83%和40.53%。而在冬季,该比例为96.66%和11.12%。2种一体化结构均能减弱室外气象参数波动对墙体内壁面热流的影响。尤其是贴合式,冬季内壁面热流的波动幅度仅占单一墙体的9.75%。
Aiming at the integrated structure of flat panel solar collector and building wall, under the combination of two types of bonding and separation, the typical meteorological days of typical meteorological years in Shanghai are used as the parameters of disturbance and the state space model The heat transfer characteristics were studied. The results show that there is little difference between the outlet temperature and the effective heat gain of the two types of integrated structure collectors and single collectors. The three outlet temperature maximum difference of 0.15 ℃. In summer, the effective heat capacity of the separated and bonded integrated structure occupies 99.89% and 97.22% of the single collector respectively in the whole day. The outlet temperature and the effective heat gain of the integrated type structure collector with the integrated structure are lower than that of the separated type . In winter, on the other hand, the ratios were 99.26% and 106.65%. In summer, the heat transfer through the enclosing structure of the detached and bonded integrated structure accounts for 90.83% and 40.53% of the single wall respectively. In winter, the ratios are 96.66% and 11.12%. The two kinds of integrated structures can reduce the influence of the fluctuation of the outdoor meteorological parameters on the heat flow on the inner wall of the wall. Especially the fit type, the fluctuation of the heat flow in the inner wall in winter accounts for only 9.75% of the single wall.
