摘要:

随着环保制冷剂R290在车用热管理系统中的推广应用,提升其系统性能与能效成为研究重点。本文创新性地提出了一种采用双芯体逆流串联换热架构的车用R290间接式热管理双二次回路系统,通过实验测试了系统的边界性能,建立了该电动汽车热管理系统仿真模型,并对比分析了该系统与单芯体换热方案、双芯体顺流串联换热方案的性能差异。研究表明,在夏季49 ℃极端制冷工况下,逆流式布置方案较单芯体方案制冷量提升11.62%,COP值可达到1.67;在冬季-20 ℃极端制热工况下,系统COP值相较于顺流串联式换热方案提升超过9.5%。本研究为R290制冷剂在车用热管理系统中的高效应用提供了重要技术支撑。

Abstract:

With the increasing application of the environmentally friendly refrigerant R290 in automotive thermal management systems, enhancing system performance and energy efficiency has become a key research focus. In this study an innovative R290-based indirect thermal management dual secondary loop system using the dual-core counterflow series heat exchange architecture is proposed. The system’s boundary performance is tested through experiments and a simulation model of the electric vehicle thermal management system is established. The performance differences between the system and the single-core and dual core parallel flow series heat exchange solutions are compared and analyzed. The results show that, under extreme summer cooling conditions (49 °C), the counterflow system increases cooling capacity by 11.62 % and achieves a COP of 1.67 compared to the single-core solution. In extreme winter heating conditions (-20 ℃), the system’s COP improves by over 9.5 % compared to the parallel flow arrangement. This research provides valuable technical support for the efficient application of R290 in vehicle thermal management systems.
