摘要

在建立喷射器全工况模型的基础上,构建太阳能喷射制冷系统的仿真模型,假设蒸发器和冷凝器换热侧水的入口参数不变,研究某太阳能喷射式制冷系统随太阳辐射变化的变工况特性,并采用多喷射器并联进行优化,结果表明,当太阳辐射为设计值时,制冷系统的性能系数与制冷量均达到最大值,当太阳辐射增大或减小时,制冷系统的性能系数与制冷量均会下降;在夏天供冷季, 3个喷射器并联的系统平均制冷量及满足供冷需求的天数比例较单喷射器均提高了约21%。

Abstract

Based on the full operating condition model of the ejector, constructs a simulation model of a solar ejector refrigeration system. The change of solar radiation not only cause temperature deviation but also affect condensing and evaporating temperature. Assuming that the inlet parameters of the water on the heat exchange side of the evaporator and condenser are unchanged, the operating performance of a solar jet refrigeration system with the variation of solar radiation are studied, and multi-ejector parallel optimization is adopted. The results show that when solar radiation is at the design value, the performance coefficient and cooling capacity of the refrigeration system reach their maximum values. As solar radiation increases or decreases, the performance coefficient and cooling capacity of the refrigeration system will decrease. During the summer, the average cooling capacity of the system with three-ejector parallel and the days meeting the cooling demand are both increased by about 21% compared to the single-nozzle system.
