本文将讨论热泵热水器环绕式冷凝器有限体积模型的建立。为了加快模拟时间，使用关联式而非CFD模拟来预测水箱到水的传热系数。针对两种不同的现有热泵热水器设计，将冷凝器模型与实验数据进行了验证，结果与模拟结果非常吻合。该工具已整合到一个完整的系统模型中，包括一个有限容积蒸发器、基于地图的压缩机、膨胀装置和管道。未来的工作将允许对该稳态蒸汽压缩循环模型进行迭代求解，以近似水温曲线随时间的动态变化。 与通常用于热水器的实验或CFD工作相比，该方法提供了准确的传热预测，开发和模拟时间很少。引用:ASHRAE论文:2015年ASHRAE年会，佐治亚州亚特兰大

This paper will discuss the development of a finite-volume model for a heat pump water heater wraparound condenser. To allow for fast simulation time, the tank-to-water heat transfer coefficient is predicted using correlations rather than CFD simulation. Validation of the condenser model against experimental data for two different existing heat pump water heater designs has shown very good agreement with the simulated results. The tool has been incorporated into a complete system model including a finite-volume evaporator, map-based compressor, expansion device, and pipes. Future work will allow this steady-state vapor compression cycle model to be solved iteratively to approximate the dynamic changes to the water temperature profile over time. The approach provides accurate heat transfer predictions with little development and simulation time as compared to experimental or CFD efforts, which are often used for water heaters.
