摘要

针对传统Trombe墙冬季热效率低、热稳定性较差的问题

提出一种中置蓄热式Trombe墙体。通过有限元流体分析软件

采用保定地区冬至、夏至日动态数据

进行连续瞬态模拟

分析蓄热材料、蓄热位置及中置墙体开口与否等9种不同形式下

室内温度、集热效率、相变材料液化率的变化情况。结果表明：在寒冷地区

冬季中置相变蓄热式双通道Trombe墙（PCM-TP）热效率可达31.6%

相比于传统Trombe墙体结构（AL-OP）高4%

日较差相对差值低2.1 ℃

夜间温度最高可提升8.23 ℃。夏季中置相变蓄热式双通道Trombe墙与传统Trombe墙体相比温度峰值时间延迟4 h

日较差相对差值低1.57 ℃。在冬季和夏季

中置相变蓄热式双通道Trombe墙（PCM-TP）性能均优于其他方案。

Abstract

Aiming at the problems of low thermal efficiency and poor thermal stability of traditional Trombe wall in winter

a central heat storage type Trombe wall is proposed. Through finite element fluid analysis software

continuous transient simulations are carried out using the dynamic data of winter and summer solstice in Baoding area

and the changes in indoor temperature

heat collection efficiency and liquefaction rate of phase change materialc （PCM） are analyzed under 9 conditions with different heat storage materials

locations

wheater the central wall is opened or closed

etc. The results show that in cold areas

the thermal efficiency of central phase change heat storage type two-channel Trombe wall （PCM-TP） can reach 31.6% in winter

which is 4% higher than that of traditional Trombe wall structure （AL-OP）

the relative daily temperature range is 2.1 ℃ lower

and the night temperature can be up to 8.23 ℃ higher. Compared with traditional Trombe wall in summer

the temperature peak time delay is 4 hours

and the relative value of daily range is 1.57 ℃ lower. In both winter and summer

the performances of the central phase change thermal storage two-channel Trombe wall （PCM-TP） are better than other schemes.
