Abstract: The implementation of liquid-vapor separation in the phase change process can achieve heat transfer enhancement. Liquid-vapor separation was applied to inverter air conditioning system. The optimal refrigerant charge amount and capillary length of the system were obtained through matching experiments. At the standard operating condition, the obtained EER and COP are 2.57 and 3.68, respectively. The system performance is also examined under different cooling and heating conditions. The annual performance factor (APF) of actual operation in different cities was compared to reflect the actual operating performance of the system. The results showed that the highest APF value was in Tengchong, at 3.67, and the lowest in Shenyang, at 2.81. It shows that the performance of the system varies significantly in different cities. Moreover, the performance at the standard operating condition largely differentiates that at the actual conditions.

Key words: liquid-vapor separation, inverter air conditioner, test, APF (annual performance factor)
