研究了非共沸混合制冷工质Ｒ１４２ｂ／Ｒ１３４ａ 和Ｒ２２／Ｒ１５２ａ／Ｒ１２４ 在花瓣形翅片管管束外的冷凝传热性能， 实验结果表明花瓣形翅片管能显著地强化非共沸混合制冷工质的冷凝传热。
The condensation heat transfer performance of non-azeotropic mixed refrigerants R142b / R134a and R22 / R152a / R124 outside the petal-shaped finned tube bundle was studied. The experimental results show that the petal-shaped finned tube can significantly enhance the heat transfer performance of non-azeotropic mixed refrigerators Condensation heat transfer.
