复合型空气-水太阳集热器热性能研究及影响因素分析

摘要

对研制的一种复合型空气-水太阳集热器建立数学模型并进行冬季空气采暖集热效率模拟。对比分析了立面90°和坡屋面45°两种安装倾角在不同工况下集热器的热性能，研究了循环介质质量流量及太阳辐射强度等因素对集热器集热效率和出口温度的影响。%The mathematical model is established by programming to simulate winter air heating collection efficiency for a kind of compound air⁃water solar collectors. We make comparative analysis for the collection efficiency of the collectors under installation angles of elevation 90° and 45° slope roof and study the influence of air flow and solar radiation intensity on collector efficiency and the outlet temperature.
