Investigation of flow and heat transfer for a split air conditioner indoor unit

► A three dimensional representative thin section CFD model was introduced. ► A psychrometric test room was used for the verification of the capacity results. ► Capacity difference between the test room data and CFD model was 0.26%. ► Velocity distribution from the CFD analyses was compared with SPIV measurements. ► Thin section model is useful for determining heat transfer and flow characteristics.
