흡입 면적에 따른 에어컨 실외기의 온도 분포에 대한 수치적 연구

다국어 초록 (Multilingual Abstract)

The outdoor unit of air conditioner is mostly installed in a place of atmosphere to dissipate heat from the heat exchanger of outdoor unit. When a room temperature is increased due to an effect of discharged air flow from the outdoor unit, the performance of heat exchanger of outdoor unit is getting worse. The intake area, which means an area of breathing fresh air from an atmosphere is a performance metric for enhancing the performance of heat exchanger of air conditioner. Therefore, we consider the intake area in order to investigate the performance of heat exchanger. In this paper, the temperature distribution depended on the intake area of the outdoor unit was investigated numerically. For numerical analysis, commercial code ANSYS 14.5 was used for the flow solver. Cut-cell mesh method was used for the modeling of the outdoor unit, and Semi-Implicit Method for Pressure Linked Equation (SIMPLE) method was used for pressure and velocity coupling. The performance of outdoor unit was evaluated by averaged HX temperature.
