Résumé

Portable air conditioners (PACs) are widely used for flexible and convenient local cooling. However, they have obvious drawbacks, including low energy efficiency and easy shutdowns due to condensate overflow in highhumidity environments. To address these issues, this paper proposes a novel flying-wing condenser and systematically investigates the effects of its key structural parameters on heat transfer, flow characteristics, and condensate management performance. Experimental results reveal that increasing the number of refrigerant inlet branches and adopting vertically arranged base tubes can effectively homogenize refrigerant flow, as well as reduce flow resistance and pressure drop. The energy efficiency ratio (EER) is improved by up to 22.38 %, with resistance loss is reduced by 15 %–20 % and pressure drop by 12 %–15 %. Compared with conventional tube-fin condensers, the flying-wing condenser allows PACs to operate continuously without drainage for at least 8 h under high-humidity conditions. Despite a 11.6 % reduction in EER and a 32.8 % decrease in heat transfer area, the proposed condenser demonstrates significantly enhanced condensate retention and evaporation performance. Overall, the flying-wing condenser is validated to be a feasible and promising substitute for conventional tube-fin condensers in PACs, especially for applications in high-humidity environments.
