| 摘 要： | 提出了一个用气—液喷射器代替机械泵的新型双喷射制冷系统。双喷射制冷系统中没有机械泵,从而循环本身不需要消耗电能。研究了气—液喷射器的运行特性和喷射系数与工作参数的关系。分析了双喷射制冷系统COP与发生器温度、冷凝器温度的关系。比较了以R123和R134a为制冷剂的太阳能双喷射制冷系统运行性能。模拟了太阳能双喷射制冷系统的运行性能,COP可达0.2-0.3。

| Abstract: | A new bi-ejector refrigeration system was presented, in which the mechanical circulation pump was replaced by a liquid-vapor ejector. Thus, no electricity power was needed in the refrigeration cycle. The relationship of the liquid-vapor characteristics, its performance and the operation parameters were investigated. The relationship between the system COP and the generator temperature, the condenser temperature was analyzed. Finally, the performance of solar bi-ejector refrigeration system was simulated and the COP could reach 0.2-0.3. |
