태양열 공기가열 집열기를 이용한 냉방 가능성에관한 해석적 연구

Abstract

The new & renewable energy including solar heat has been widely used to reduce the fossil fuel. Air-heating collector of solar heat is usually known as technology that supplies the hot air to indoor room. However, this study aims to investigate the possibility of cold room by air-heating collector of solar heat. The thermal flow in cold room was simulated using ANSYS-CFX program and thus the behaviors of cold air were evaluated with standard k-ε turbulence model. As the results, there was space in indoor room not showing cooling effect in case that both inlet and outlet were installing at bottom. Inlet temperature showed greater cooling effect than inlet velocity. Furthermore it was confirmed that the location and the temperature, respectively, capable of cooling indoor room could be predicted by changing the attached position of inlet and outlet.
