摘要:
分析了太阳能毛细驱动喷射式空调器的工作原理,建立了系统各主要部件的传热传质单元模型,采用迭代法和子程序交换技术,对系统的制冷量和工作特性进行了数值模拟.研究结果表明:太阳能毛细驱动蒸汽喷射式制冷系统的制冷量和性能系数主要受太阳辐照强度、发生压力、冷凝压力和蒸发温度的影响; 系统的制冷量和性能系数随发生压力的升高而升高,随冷凝压力的升高而降低,随蒸发温度的升高而升高; 对于特定的系统,系统的运行状况存在若干个最佳工况点; 系统的发生温度在75~80 ℃以上、冷凝温度在35 ℃以下时,系统能正常运行.
Abstract:
A numerical model for modeling the performance of a capillary ejector refrigerator driven by solar energy is developed. The flow and heat transfer characteristics in solar collector, generator, ejector, condenser and evaporator are analyzed and calculated. The performances of the system are calculated by use of iteration method and a sub-routine transfer technique. The results show that the cooling capacity and the coefficient of performance(COP)of the system depend mainly on solar radiation intensity, generating and condensing pressure, as well as evaporating temperature. The cooling capacity and COP increase with increasing the generating and evaporating temperature and decrease with increasing the condensing pressure. There exist some optimum operation points owing to the inherent characteristics of the ejector. When the generating temperature is higher than 75-80 ℃ and the environmental temperature is lower than 35 ℃, the system can work normally.
