Investigation of Vapor Ejector in a Heat Pipe Ejective Cooling System

针对热管式太阳能制冷系统,分析了影响系统制冷性能的主要因素,并对喷射器内的压力和速度场进行了数值模拟。结果表明,热管式太阳能喷射制冷系统受太阳辐照强度、发生室温度、冷凝器温度和蒸发温度的影响;系统制冷性能系数随发生器内温度的升高而升高,随冷凝温度的升高而降低,随蒸发温度的升高而升高。

In this paper, the system performance changing with the time of solar irradiance is analyzed in heat pipe cooling system and the numerical simulation of the pressure field and the flow flied is made in the ejector. The results show that the heat pipe ejective cooling system depend mainly on solar radiation intensity, generating and condensing temperature, 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.
