Abstract: At present, there are many manufacturers and product types of room air conditioners in China. Due to the different market positioning of manufacturers and products, the performance and energy efficiency of air conditioners at different prices show obvious differences. In order to analyze the reasons for the differences between different products and the specific composition of product parts, three models of air conditioners with different prices and different energy efficiency grades of two domestic large-scale air-conditioner enterprises were disassembled, and the parameters of indoor and outdoor heat exchangers,electrical components and fans were compared, and the impact of the differences was briefly analyzed according to the experimental test data. This study is helpful for the researchers of china to have a better understanding of the parameters of air conditioner parts and the influence of parts changes on the whole machine, so as to guide the development of new products.
