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.
