| 摘 要： | 可用能理论是一种有效分析能量利用效率的方法。本文在分析了建筑物太阳能加热系统的可用能损失和可用能效率基础上,对太阳能热水系统加热过程进行热力学参数计算。结果表明,太阳能热水系统中,太阳能集热器的可用能效率最低,所引起的可用能损失率最高,其次为循环泵和换热器。同时,为提高太阳能加热系统的整体能量利用效率提出了改进方向。 |

| Abstract: | Available energy theory is an effective method of energy efficiency. Based on the analysis of the building solar energy heating systemsloss and energy efficiency, solar hot water system heating process calculation of thermodynamic parameters are given. The results show that in the solar water heating systems, solar energy collectors available energy has the least efficient and highest rate of available energy loss, followed by the circulation pump and heat exchanger. Meanwhile, the direction of solar heating systems to improve overall energy efficiency improvements is put forward. |
| Keywords: | building solar energy hot water system available energy |
