摘要

本文建立了热泵干衣机数学模型，包括稳态的热泵系统模型和动态的衣物干燥过程热质交换模型。模型与实验进行了对比，干衣时间的误差小于3 min，耗电量的误差为-2.3%。利用模型仿真研究了各部件大小的匹配关系对单位能耗除湿量SMER和干燥时间的影响，并对重要的系统参数如循环风量、新风比例和制冷剂充注量进行了优化研究。结果表明，循环风量180 m3/h、新风比例9%~10%时SMER最大；在冷凝温度限值之内，增加充注量有利于SMER的提高。研究结果可供热泵干衣机设计参考。

Abstract

A model of heat pump clothes dryer was developed in this paper

which includes the steady-state heat pump system model and the dynamic fabric drying process model. The simulation results reached a good agreement with the test data of a household heat pump clothes dryer. The drying time error is within 3 minutes and the electricity consumption error is -2.3%. Based on the model

the impact of component size and key system parameters (such as circulation air flow rate

ratio of circulating air

and refrigerant charge) on SMER (Specific Moisture Extraction Rate) and drying time were analyzed. The results indicated that maximum SMER would be achieved at 180 m3/h circulation air flow rate and 9%-10% fresh air to circulating air. Within condensing temperature limit

more refrigerant charge would favor SMER. The results are useful for the system design of heat pump clothes dryer.
