光伏蓄能恒温库系统数值模拟分析
Numerical Simulation Analysis of Photovoltaic Energy Storage Constant Temperature Storage System
摘要
Abstract
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.关键词
