摘要
太阳能喷射式制冷系统在满足供冷需求时,通常需要补充一定量的一次常规能源,其节能条件及应用范围是急需解决的问题。在系统能量平衡的基础上,引入太阳能倍率等参数,推导了太阳能喷射式制冷系统与电压缩制冷系统的一次能耗比计算公式,进而对太阳能喷射式制冷系统与电压缩制冷系统的一次能源消耗进行了对比分析。并以太原为例,确定了太阳能喷射式制冷系统的平衡太阳能倍率,给出了相对于电压缩制冷的太阳能喷射式制冷的节能条件。
Supplement of primary energy is needed to a solar ejector refrigeration system （SERS） in order to meet the cooling need of the user, so the energy-saving conditions and the application range of a SERS is needed to be discussed first. On the basis of energy equilibrium, equations of primary energy demand ratio between a SERS and a compression chiller are derived by introducing solar fraction. The primary energy consumption of a SERS with a coal-fired boiler supplement source is compared with that of a compression chiller. Finally, the solar fraction on the balance spot and the energy-saving conditions of the SERS in Taiyuan are confirmed.
