摘　　要：矿井排风、矿井涌水余热常年具有稳定的温度,不受环境和季节影响等特征,因此将该部分低品位热能转化高品位热资源具有显著的环保和经济效益。高温热泵系统可有效地将其提升至高温以满足工业多场景用能需求。为探究高温热泵系统在变工况下的动态性能,以搭建的高温热泵系统实验台为研究对象,对其在不同内、外部条件变化下系统的动态特性进行实验研究。实验结果表明,高温热泵系统在不同条件变化下,其对系统内部参数稳定性影响的因素依次排序为:内部中间压力>热源温度>负荷侧制热温度>热源侧水质量流量。同时结果还表明中间压力对高温热泵机组的能耗和制热能力有较大影响,这为高温热泵系统的下一步动态优化工作提供了指导。Mine exhaust air and inrush mine water possess waste heat with a stable temperature all yearround,and such heat is not affected by the environment or seasons.Therefore,converting this part oflow-grade heat energy into high-grade heat resources has significant environmental and economic benefits,and high-temperature heat pump systems can effectively complete the conversion to meet the industrial energy demand in multiple scenarios.In order to investigate the dynamic performance of the hightemperature heat pump system under variable operating conditions,an experimental bench of the hightemperature heat pump system was built,and its dynamic characteristics under different internal and external conditions were experimentally investigated.The experimental results reveal that the factors affecting the stability of the internal parameters of this system under different conditions conform to the following order:internal intermediate pressure>heat source temperature>load-side heating temperature>heatsource-side water mass flow rate.In addition,the intermediate pressure has a large impact on the energyconsumption and heating capacity of the high-temperature heat pump system.The results are expected toprovide guidance for the follow-up dynamic optimization of the high-temperature heat pump system.
