Abstract

This study investigated the effect of a performance booster (PB) on the performance of a window-type air conditioner (WAC). The PB was fabricated using perforated aluminum plates with different pore size configurations according to the return air distribution of evaporator. The WAC was tested under various outdoor air conditions, and the performance of the WAC before and after PB installation was compared. Results showed that the PB effectively improved the performance of the WAC. The PB with three pore sizes improved the WAC performance more than the PB with two pore sizes. The maximum improvements in the WAC’s cooling capacity, dehumidification capacity, and energy efficiency ratio (EER) under the configuration with three pore sizes were 13.70 %, 59.63 % and 14.37 %, respectively, compared with the original WAC at an outdoor dry-bulb temperature of 30 °C.
