为解决相变储能箱耦合太阳能空气源热泵供热系统关键参数的设计问题，设计了基于TRNSYS软件的相变储能箱耦合太阳能空气源热泵供热系统模型。利用GENOPT软件调用HookeJeeves算法，以费用年值为优化函数，针对集热器面积、空气源热泵制热量、集热器倾角、集热器方位角、相变储能箱体积以及体积因子等关键参数进行优化分析，并以单位体积下相变储能箱蓄/放热量、集热器逐月平均效率及系统性能系数COPS为优化前后评价指标。结果表明：集热器面积取187 m2、空气源热泵制热量取40.5 kW、集热器倾角取44.1°、集热器方位角取-1°、相变储能箱体积取4 m3、体积因子取0.1时得最小费用年值，费用年值同比降低21%；优化后单位体积下，相变储能箱年放热量提升了15.1%，年蓄热量提升了16.5%；以系统性能系数COPS为评价指标，优化后系统整体性能受环境因素影响下降，系统更趋于稳定运行。

In order to solve the design problem of the key parameters of the heating system of phase change storage tank coupled with solar air source heat pump, a heating system model of phase change energy storage tank coupled with solar air source heat pump based on TRNSYS software was designed. The HookeJeeves algorithm was invoked by using GENOPT software, and the annual cost value was taken as the optimization function. The key parameters such as collector area, heat produced by air source heat pump, collector inclination, collector azimuth, volume and volume factor of phase change storage tank were optimized and analyzed. The heat storage and release of phase change energy storage tank per unit volume, monthly average collector efficiency and coefficient of performance (COPS) were used as evaluation indexes before and after optimization. The results show that the minimum annual cost value is obtained when the collector area is 187 m2, the heat produced by the air source heat pump is 40.5 kW, the collector inclination is 44.1°, the collector azimuth is -1°, the volume of phase change energy storage tank is 4 m3 and the volume factor is 0.1, which is reduced by 21% year over year; after the optimization, the annual heat release per unit volume of phase change energy storage tank increases by 15.1%, and the annual heat storage per unit volume of phase change energy storage tank increases by 16.5%; with the COPS as the evaluation index, the overall system performance decreases due to environmental factors after optimization, and the system tends to run more stably.
