摘要:
以太原地区的气象参数为背景,利用TRNSYS仿真软件,模拟计算以R141b为制冷剂的蓄热型太阳能喷射制冷系统在夏季典型日的性能,分析系统的喷射系数、制冷量、能效比(COP)随着太阳辐射照度的逐时变化,以及蒸发温度、冷凝温度、喷射器喉部面积比(r)对系统性能系数的影响.结果表明:系统的性能随太阳辐射照度增强而提高;蓄热装置的使用拓宽了系统高效运行的时间,更加有效地利用了太阳能;在系统运行时段,各性能系数逐时变化趋势一致,且随着蒸发温度的升高而增大,随着冷凝温度的升高而减小;同一工况下,r值越大喷射系数越大,
Abstract:
By using weather parameters in Taiyuan area as background, performance of a solar ejector refrigeration system with heat storage which used R141b as refrigerant in summer typical weather days was simulated and calculated by TRNSYS. The hourly variation conditions of the performance of the system such as entrainment ratio, refrigerating capacity and coefficient of performance(COP)with solar radiation intensity were analyzed. And the effect of evaporation temperature, condensation temperature and ejector throat area ratio(r)on the performance of the system were also analyzed. Results show that the performance of the system increases with the increasing of solar radiation intensity. Using the heat storage tank device can broad the efficient running time of the system, and then uses the solar energy more effectively. In the system operation period, the hourly variation trend of every coefficient of the performance of the system is consistent, and increases with the rising of evaporation temperature and decreases with the rising of condensation temperature. Under the same conditions, r is larger, the greater the entrainment ratio, maximum refrigerating capacity and COP. And r is equal to 8.8, an average COP of 0.276 can be achieved, which is the biggest of all.
