| Abstract: | Numerical model of the flow channel in indoor unit of an air-conditioner is set up by the method of CFD, and a parameter of eccentricity of,which is used to describe the inlet flow direction, is defined in this paper. In order to optimize the inlet flow state, improve the flow and reduce the noise of the cross-flow fan through rationally arranging front plate and heat exchanger of ＇the air-conditioner, the impact on velocity distribution of inlet and eccentricity flow state of the cross-flow fan which is caused by different kinds of front plate and heat exchanger is analyzed, and the relationship between inlet flow state of the cross-flow fan and the performance of the air-conditioner is discussed. |
