【摘要】 热泵系统仿真技术在过去的几十年中经过了快速发展,通过建立系统模型进行仿真计算,快速预测系统性能,进而减少样机调试周期和实验费用,同时还可以预测很多实验中难以测量的参数,为优化系统提供理论依据;热泵干衣机系统存在两个闭合循环:制冷循环和空气循环,相比空调制冷系统的稳态过程,热泵干衣机的烘干过程是一个随时间变化的动态过程,更具复杂性。本文以热泵干衣机为研究对象进行模型开发,建立了动态响应的热泵系统稳态模型,从时间和空间两个维度,建立了环境温度、湿度、衣物材质、衣物重量的多因素动态筒模型,并协同电机模型、散热模型、旁路系统以及新风系统等,实现了对实际干衣过程的烘干时间,系统能耗的准确预测;同时通过成本优化,提出了全铝换热器降本方案,依然可以满足能效需求,对于指导干衣机开发具有指导意义。更多还原

【Abstract】 The simulation technology of heat pump system has undergone rapid development in the past decades.Through the establishment of system model for simulation calculation,the system performance can be quickly predicted,thus reducing the prototype debugging cycle and experimental costs. At the same time,it can also predict many parameters that are difficult to measure in experiments,providing a theoretical basis for optimizing the system. The heat pump dryer system has two closed cycles:refrigeration cycle and air cycle. Compared with the steady-state process of the air conditioning refrigeration system,the drying process of the heat pump dryer is a dynamic process that changes with time and is more complex. This paper takes heat pump dryer as the research object to develop the model and establish the steady-state model of the heat pump system with dynamic response. From the two dimensions of time and space,the multifactor dynamic cylinder model of ambient temperature,humidity,clothing material and clothing weight is established.In addition,the drying time of the actual clothes drying process is realized by cooperating with the motor model,heat dissipation model,bypass system and fresh air system. Accurate prediction of system energy consumption;At the same time,through cost optimization,the all-aluminum heat exchanger reduction scheme is proposed,which can still meet the energy efficiency demand,and has guiding significance for guiding the development of clothes dryer.更多还原
