This study explored the effects of different designs of a heat transfer augmentor (HTA) on the performance of window air conditioners (WACs). A HTA was fabricated from perforated aluminum plates with different pore diameters according to the surface temperature distribution of the evaporator. The WAC was tested under the T1 condition of CNS14464, and the performance before and after the installation of the HTA was compared. The experimental results showed that the pore diameters of the HTA in proportion to the surface temperature of the evaporator could effectively improve the performance of the WAC. The dehumidification capacity and the energy efficiency ratio (EER) were increased by 22.05% and 3.49%, respectively, compared with the original WAC.
