Abstract: The energy efficiency requirements of market products are becoming more and more standardized and upgraded year by year. Dehumidifier products are also facing the same problem. On the one hand, they are facing the requirements of the miniaturization of the fuselage, on the other hand, they are facing the demand of greatly improving the energy efficiency coefficient. Therefore, it is proposed to study and improve the heat exchange effect and optimization strategy of the condenser of the dehumidifier to meet the market demand and customer requirements.

Key words: Single-row tandem, Multi-row, Condenser, ø5 mm pipe, Energy efficiency coefficient
