摘　　要：针对月球表面温度变化范围大,导致基地内部热量无法排散的问题,提出了采用热泵排热的概念。从热泵工质的选择,改变排热温度、废热量、电源及辐射器比重等方面分析了热泵系统质量变化。结果表明:月球表面温度高达400 K,应选择临界温度较高的工质,如R1 1、R717;在废热量一定的情况下,上述参数变化时存在一个最佳系统质量和最佳排热温度;废热量越大热泵系统越重。月球基地采用热泵技术能够有效强化排热能力,从而达到减重的目的。The heat from the lunar base was not rejected because there was a large temperature range on lunar surface,and a concept of heat pump used to reject the heat was proposed.A optimal study which can lighten the system mass was performed by qualifying the effects of several parameters such as the refrigerants,heat rejection temperature,cooling load,power supply specific mass,and radiator specific mass.The results indicate that the refrigerants whose critical temperature is high,such as R11 and R717,should be chosen since lunar surface temperature is 400 K in daytime.An optimal system mass and heat rejection temperature is calculated when the cooling load is a constant.Meanwhile,the heat system mass is larger as the cooling load increases.Lunar base using a heat pump system can enhance the heat rejection and reduce the total mass of the thermal control.
