To analyze the performance of the heat exchanger (HEX) in air-conditioners within a realistic time frame, we propose a simple modeling technogy 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 in a 1.0-1.6-mm fin pitch range with experimental results. The pressure loss of the simple analysis model agreed with that of the experimental result, within 3% error, and the heating capacity of the simple model agreed with that of the experimental result, within 1% error.
