중앙 집중식 차량 공조장치의 개발을 위한 CFD 해석

In this paper, airflow and heat transfer analyses for a center mounting HVAC system were performed using commercial CFD code. For the bi-level mode of the HVAC system, the rate of airflow through the system has its maximum value when the temperature-controlling door is at quarter opening rate. As temperature-controlling door opens wide, the static temperature at every outlet of the system increases showing the linearity with respect to the opening rate of temperature-controlling door. Although there was difference in temperature between each outlet, the magnitude of temperature difference was considered to be acceptable.
