摘　　要：针对新风空调机组，采用倾角为15°的分离式热管用于显热回收。研究充液率，迎面风速及空气进口温度对显热效率的影响，分析了其影响规律。研究表明，采用热管空调机组设计风速范围内，充液率介于66％-75％时，其换热效率最高。迎面风速较低时，空气进口温度介于34℃-36℃，其显热效率较高。因此，采用分离式热管机组适合用于高热地区作为新风机组，可最大限度回收显热。Seperated heat pipe heat recovery （SHPHR） with an inclination of 15°for the fresh air handling unit was presented. The sensible heat ratios of SHPHR were analyzed based on the different filling ratios, air - facing velocity and air inlet temperature. The result shows that the filling ratios between 66% -75 % have its high thermal efficency, with design air - facing velocity of the fresh air handling unit; If the air - facing velocity is lower and air inlet temperature is between 34℃-36℃, SHPHR has high thermal efficiency. It is recommended that tropical HVAC systems should be installed with heat pipe heat exchangers for thermal recovery.
