Summary

This study is an analysis of energy efficiency improvement and manufacturing cost relationship of inverter type 3 ~ 6 kW wall-mounted air conditioner in Korea. The analysis of manufacturing cost was based on the reverse engineering method. The efficiency of the system was measured by the combination of the indoor unit and the outdoor unit under the cooling standard conditions. The results of the analysis were obtained the correlation equation by using the regression equation of cost and efficiency. System efficiency increased by 19% and cost increased by 46% when the compressor efficiency increased by 20% in the reference model. In the reference model, the efficiency increased by 12% and the cost increased by 14% when the condenser cross-sectional area increased by 60%. As the evaporator cross section increases, system efficiency and cost increase. In the reference model, efficiency and cost increased by 1% as the evaporator cross-sectional area increased by 10%. The manufacturing cost of air conditioner was increased as the efficiency increases. As the factors affecting the efficiency of the system, the manufacturing cost increased greatly.
