摘要
冰箱能效和容积率是冰箱设计中一个关键指标,风冷冰箱冷量耦合计算可实现冰箱能效指数和容积率的优化设计。利用计算流体力学软件ANSYS和换热器测试设备对冰箱用蒸发器分别进行仿真和实验,从蒸发器风循环侧换热量对冰箱整机能效影响进行研究。结果表明:将蒸发器体积减小,同时配合优化16℃和32℃两种环温下风扇转速,调整流过蒸发器的风速,可保持标准耗能效指数不变,有效提升冰箱容积率1.9%。
Refrigerator energy efficiency and floor area ratio is a key indicator in refrigerator design.The cooling capacity coupling calculation can realize the optimized design of refrigerator energy efficiency and floor area ratio.This paper uses computational fluid dynamics software ANSYS and heat exchanger test equipment to simulate and experiment on refrigerator evaporators,and study the effect of heat exchange of evaporator on the energy efficiency of refrigerators from the side of evaporative air circulation.The results show that the standard energy efficiency index can be kept unchanged by changing the three-row oblique-insertion evaporator to two-row oblique-insertion evaporator,and at the same time adjusting the fan speed under the power consumption state of 16℃and 32℃.Effectively increase the floor area ratio of the refrigerator by 1.9%.
