摘要
提出了一种可用于强化空间辐射器排热的新概念———光伏热泵技术,对影响热泵排热系统质量的几个敏感参数,如:辐射器工作温度和比重,光伏电源系统比重,空间等效热沉温度以及蒸发器集热温度等进行了分析,得到了不同参数值所对应的热泵系统最优重量和最优排热温度。分析表明,利用热泵能达到强化空间辐射器排热能力和降低热控系统质量的目的,显示了热泵在未来空间应用中的巨大潜力。
In this paper,a novel concept based on photovoltaic heat pump augmented space radiator heat rejection was presented.An optimization study was performed to quantify the effects of several sensitive parameters such as operating temperature and specific-mass of radiator,solar photovoltaic power supply mass penalty,effective heat sinking temperature and acquisition temperature of evaporator on total mass of heat pump systems.The optimal rejection temperature and optimal mass of the heat pump system were calculated under various parameters.The analytical results show that the heat pump system can enhance heat rejection of space radiator and reduce the total mass of thermal control system of spacecraft,also show its promising prospects in future aerospace applications.
