To analyze the performance of the heat exchangers (HEXs) in air-conditioners within a realistic time frame, we propose a simple modeling technology that uses a reduced mesh. The pressure loss of the HEX is given by the momentum source term, and the heat-transfer performance of the HEX is approximated by using a wall function as the boundary condition. We compared analytical results of this simple analysis model with the measured results for heating conditions for different indoor systems. The air-flow rate of the simple analysis model agreed with that of the experimental results within a 1% error margin, and the heating capacity of the simple model agreed with that of the experimental result within a 2% error margin.
