【摘要】：针对生物质能作为辅助能源用于太阳能吸附制冷系统供冷的适配性,以已搭建的太阳能与生物质能联合驱动吸附式制冷试验台为研究对象,试验研究了双热源联合运行供能耦合的可能性。采用MATLAB软件动态模拟了双热源串、并联运行工况,并借助非线性最小二乘法对数据进行处理、分析。结果表明:串联运行时,按照模式2工况循环流动,可较好地实现系统热量的传递;并联运行时,通过对太阳能与生物质能联合供能的适配性研究,结合系统末端供冷需求和经济运行模式分析,得出太阳能与生物质能联合供能的最佳回水流量分配比值范围为0.5~0.6,提出适宜于双热源联合供能3种经济运行模式。研究结果可为改善制冷系统性能的稳定性、实现太阳能与生物质能的有效结合提供参考。
[Abstract]:In view of the adaptability of biomass energy as auxiliary energy to the cooling of solar adsorption refrigeration system, the research object is the adsorption refrigeration test-bed driven by solar energy and biomass energy. The possibility of energy supply coupling by combined operation of two heat sources has been studied experimentally. MATLAB software is used to dynamically simulate the operating conditions of double heat source string and parallel operation, and the data are processed and analyzed by means of nonlinear least square method. The results show that the heat transfer of the system can be realized better when running in series, and the adaptation of solar energy and biomass energy supply can be studied in parallel operation. Based on the analysis of system end cooling demand and economic operation mode, the optimal ratio of return water flow distribution of solar energy and biomass energy supply is obtained in the range of 0.5 ~ 0.6, which is suitable for three economic operation modes of combined energy supply from two heat sources. The results can provide a reference for improving the performance stability of refrigeration system and realizing the effective combination of solar energy and biomass energy.
