摘要

本文建立了一个耦合模型来模拟螺旋冷凝器盘管与水箱内水之间的换热过程。利用ANSYS Fluent计算流体动力学(CFD)软件建立了该耦合模型。冷凝器盘管的热流密度由实验研究得到,并作为初始边界条件传递给水箱模型。获得的结果被认为是必不可少的,并且反过来能够评估用于生产热水的改进的家用冰箱的性能。根据该模型,结果证实了传热系数和系统性能随加热时间的增加而降低。在整个加热周期内,自然传热系数Uc从727.26[公式:见文]W[公式:见文]m[公式:见文]K[公式:见文]降至68.64[公式:见文]W[公式:见文]m[公式:见文][公式:见文]K[公式:见文],水温从20°C上升到50.73°C。此外,本文还考虑了水温对蒸发区域的影响。因此,蒸发器的温度不受热水发展的影响。研究结果可为国产浸入式冷凝器盘管制冷机的研制提供参考。

Experimentally Validated Model of a Domestic Refrigerator with an Immersed Condenser Coil for Water Heating
This study presents a coupled model to simulate the heat transfer process between the helical condenser coil and the water inside the tank. This coupled model was developed using ANSYS Fluent Computational Fluid Dynamics (CFD). The heat flux of the condenser coils is obtained from our experimental investigation and delivered as initial boundary conditions to the tank model. The results obtained are considered essential and are, in turn, capable of assessing the performance of the modified domestic refrigerator for the production of hot water. According to this model, the results confirmed that the coefficient of heat transfer and the performance of the system decreased with an increase in the heating time. The natural heat transfer coefficient Uc falls from 727.26[Formula: see text]W [Formula: see text] m[Formula: see text] [Formula: see text] K[Formula: see text] to 68.64[Formula: see text]W [Formula: see text] m[Formula: see text] [Formula: see text] K[Formula: see text] during the total heating cycle, and the water temperature rises from 20∘C to 50.73∘C. In addition, the impact of water temperature on the evaporating region was used in this analysis. Therefore, the temperature of the evaporator is unaffected by the development of hot water. As a result, these outcomes will be used for the development of the domestic refrigerator with immersed condenser coil.
