建立了吸收式热泵系统中氨水冷凝器的设计模型。氨水混合物以过热蒸汽的形式通过螺旋槽管进入冷凝器，冷却后冷凝成液体，进一步过冷。循环流体在绕盘管的环形通道中以受限横流流动。螺旋槽管用于强化混合物中的传热传质和循环侧的传热。根据传热机理的特点，将氨水冷凝器分为四个不同的区域:过热蒸汽区、精馏区、冷凝区和过冷液体区。研究了每个区域的传热系数、蒸汽入口浓度和槽管的几何细节对换热器尺寸的影响。给出了设计结果。关键词:1996年，设计，冷凝器，氨，水，扩展表面热交换器，热交换器，传热系数，热流，性能沉淀: 研讨会，ASHRAE Trans。1996年，第102卷，第2部分

Develops a design model of an ammonia-water condenser in absorption heat pump systems. An ammonia-water mixture enters the condenser through a helically coiled fluted tube as a superheated vapour, cools, and then condenses into a liquid, which is further subcooled. The hydronic fluid flows in the annular channel around the coiled tube in confined cross-flow. The helically coiled fluted tube was used to enhance heat and mass transfer in the mixture and heat transfer in the hydronic side. The ammonia-water condenser was divided into four different regions according to the characteristics of the heat transfer mechanisms - superheated vapour, rectification, condensation, and subcooled liquid regions. Studies the effects of heat transfer coefficients in each region, the inlet concentration of vapour, and the geometric details of the fluted tube on the heat exchanger size. Presents the design results.KEYWORDS: year 1996, designing, condensers, ammonia, water, extended surfaces heat exchangers, heat exchangers, heat transfer coefficient, heat flow, properties
