摘　　要：为了优化太阳能耦合土壤源热泵系统(SGSHPS)的配置,以沈阳地区办公建筑为例,基于TRNSYS平台建立了不同运行模式的SGSHPS模型,对比分析不同模式下系统运行30 a后土壤温度不平衡率和系统总能耗;以并联过渡季蓄热模式为对象,对不同的太阳能集热系统和地埋管换热器组合方式进行模拟;在保证系统稳定的前提下,以动态费用年值最低为目标,优化太阳能集热器面积和地埋管换热器钻孔数的配置方式;引入粒子群优化-多输出支持向量机回归(PSO-MSVR)算法,使用PSO算法生成MSVR模型参数并寻找最优值。结果表明:与采用传统热平衡法确定的配置方式相比,优化后运行30 a的系统能耗降低379522 kW,节能11.2%,费用年值降低61863元,土壤温度仅上升0.73 K;对于不同的太阳能集热器和地埋管换热器造价,优化后费用年值相较优化前仍有不同程度的节省,且土壤温度均未有较大偏移。Taking office building in Shenyang region as an example,a solar coupled ground source heat pump system(SGSHPS)model with different operation modes was established based on TRNSYS platform to optimize the configuration of SGSHPS.The soil temperature imbalance ratios and total energy consumption of the system after operation for 30 years in different modes were compared and analyzed.Using the parallel transition season thermal storage mode as the research object,different sets of solar collector systems and buried tube heat exchanger combination methods were simulated.Under the premise of stable system operation,the configuration of the solar collector area and the number of buried tube heat exchanger boreholes were optimized for minimum dynamic annual cost value.PSO-MSVR algorithm was introduced.PSO algorithm was used to generate the MSVR model parameters,as well as to find the optimal values.Results show that compared with the configuration method determined by the traditional heat balance method,the system energy consumption after operation for 30 years reduces by 379522 kW for the optimized configuration method,which means energy saving of 11.2%.The annual cost reduces by 61863 yuan,while the soil temperature only increases by 0.73 K.For different solar collector and buried tube heat exchanger costs,the annual costs after optimization reduce by different degrees compared with before optimization,and the soil temperature has not been greatly shifted.
