摘　　要：为进一步降低热泵系统冬季能耗,减少恒温库能源消耗情况,本文提出了一种新型光伏驱动蓄能型恒温库系统。基于TRNSYS仿真系统,构建了太阳能-热泵蓄能型热力耦合数学模型,对该恒温库系统进行数值模拟和理论分析。结果显示,在新型光伏驱动蓄能型恒温库系统运行下,库内温度可以稳定维持在-2.0~3.7℃保持24 h,在稳定运行过程中热泵系统运行效率保持在3.0~4.0,系统平均性能系数(COPa)可以达到1.9,系统运行功率在0~0.7 kW,系统24 h累计制热量达到了18.0 kW·h,日平均累计消耗市电仅6.8 kW·h。结果表明,该系统可以为节能型恒温库提供一种设计依据。In order to further reduce the energy consumption of heat pump system in winter,reduce the energy consumption of constant temperature storage,a new type of photovoltaic driven storage constant temperature library system is proposed in this paper.Based on the TRNSYS simulation system,a solar-heat pump energy storage thermodynamic coupling mathematical model is constructed,and the numerical simulation and theoretical analysis of the constant temperature storage system are carried out.The results show that under the operation of the new photovoltaic driven energy storage type constant temperature library system,the temperature in the storage room can be stably maintained at-2.0-3.7℃ for 24 hours.During the stable operation,the operating efficiency of the heat pump system can be maintained between 3.0 and 4.0,the average coefficient of performance of the system can reach 1.9,and the operating power of the system is 0-0.7 kW.The cumulative heat produced by the system reached 18.0 kW·h,and the average daily accumulative consumption of electricity was only 6.8 kW·h.The results show that the system can provide a design basis for energy-saving constant temperature storage.
