摘要
本文用热力学基本定理分析了太阳能集热器进口温度和流量对其(火用)效率的影响;提出了全天最佳进口温度和全天最大(火用)效率的概念并结合实例作了计算.
The efficiency of a flat-platf solar collector is investigated in terms of its exergy delivery. The exergy output will be a maximum under optimum entrance conditions. The optimum entrance temperature for the whole day is defined, at which the exergy efficiency of the whole day is maximum through continuously regulating the entrance mass flow rates.
