摘要/Abstract

摘要： 在家电领域,降低碳排放、提高产品能效水平是近些年的发展趋势。洗碗机产品由于洗涤温度和烘干餐具的要求,加热方式以电加热为主,能耗值较高。基于某平台电热洗碗机产品的工作特性,建立一维热仿真模型并描述洗涤周期中的传热过程和能量分布,总能耗预测误差小于4%,并从餐具吸热量的角度提出表征餐具洗净程度的特征参数——洗净因子。并进一步根据NLPQL优化算法对洗碗机能耗进行优化设计,研究发现在保证相同洗净水平时其能耗可降低6%,研究结论对洗碗机产品设计中平衡能耗和洗净效率具有参考价值。

Abstract: In the field of home appliances, reducing carbon emissions and improving the energy efficiency level of products have been the development trend in recent years. Dishwasher products are mainly heated by electric heating due to the requirements of washing temperature and drying dishes, and the energy consumption value is high. Based on the working characteristics of a platform electric dishwasher product, a one-dimensional thermal simulation model is established and the heat transfer process and energy distribution in the washing cycle are described, and the total energy consumption prediction error is less than 4%, and the characteristic parameter characterizing the degree of dishwashing from the perspective of heat absorption of tableware—washing factor is proposed. The energy consumption of the dishwasher is further optimized according to the NLPQL optimization algorithm, and it is found that the energy consumption can be reduced by 6% with the same washing level, and the findings are of reference value for balancing energy consumption and washing efficiency in dishwasher product design.

Key words: Dishwasher, One-dimensional heat transfer simulation, Washing factor, Optimized design
