기류에 따른 가정용 인버터 에어컨의 쾌적성 향상에 관한 실험적 연구

An Experimental investigation on the thermal comfort improvement according to the variation of air flow for the inverter driven residential air conditioner was conducted. This study presents an improvement method to reduce cold draft using hybrid flow path in the inverter driven wall mount split type residential air conditioner. To investigate the effect of the hybrid flow path, we measured the air flow velocity, temperature distribution and PMV, PPD under wind-free mode and compared to general cooling mode. Under wind-free mode, occupant zone was formed in still air condition(under 0.15m/s) and maintained uniform temperature distribution. Therefore, PMV and PPD were improved to meet the ASHRAE comfort zone
