摘要
海水源热泵区域供热作为一种可再生能源的利用技术,其节能与否的判定对于其在我国沿海地区的推广应用具有重要的现实意义.通过将该系统与传统的区域锅炉房供热系统在用能方面的对比分析,推导并计算出了在一般的工程条件下,当海水源热泵区域供热系统比传统的区域锅炉房供热系统节能时,海水热泵机组制热性能系数应达到的下限值的表达式.具体的计算结果表明,该制热性能系数的下限值不仅随锅炉热效率的提高而升高,而且还随区域供热半径的增加而增大,因而较小规模的区域供热系统更有利于海水源热泵系统节能特性的体现.
As renewable energy utilization technology, whether a seawater source heat pump district heating system is really energy-saving has great significance on the popularization of the system along the seaside area in China. By the comparison between the system and the traditional boiler house district heating system on energy consumption, an energy-saving criterion was deduced, which was the expression of the lower limit of the coefficient of heating performance of the seawater source heat pump unit （coph） in common engineering circumstances. The calculation results show that the lower limit of coph is not only raised with the enhancement of boiler house heating efficiency but also with the increment of the heating district radius, and hence a relatively small-scale district heating area is more advantageous for the seawater source heat pump district heating system with respect to energy efficiency.
