摘要 基于寒冷地区地源热泵运行的实验数据,建立了串联式太阳能辅助地源热泵供暖系统优化数学模型,并用约束变尺度法获得最优解。根据优化方法,以综合考虑系统运行性能和经济性为原则,对一实际工程进行了最优化研究。结果表明,采用优化设计后,系统总投资与采用传统设计时大致相当,但机组供暖运行性能有明显提高,COP提高了约16.7%,总功耗下降了17.2%,年均总成本降低了11.8%。 Based on the experiment for heating with ground coupled heat pump (GCHP) in cold region, a mathematical optimization model was set up and solved by WHP for a geo-solar com- bined system, in which the solar collector worked as an assisted source for the GCHP system. The results were analyzed and applied to the design of an actual project considering both the perfor- mance and economics under combination mode. The optimum design showed great advantages over the conventional one, which achieved a 16.7% improvement in COP at 17.2% less energy consump- tion and 11.8% lower annual eost, respeetively.
