针对电动汽车设计了一种新型的串联式CO2热泵系统,并对其性能进行了研究。建立了数值模型,并进行了空调和热泵工况下的实验验证。在验证模型的基础上,讨论了环境温度、排气压力和排气温度对系统的影响。此外,传统的CO2系统和新型的SGC热泵系统进行了比较,使用开发的模型。该模型在AC工况下预测系统容量和COP的平均误差为5.1%和6.0%,在HP工况下预测系统容量和COP的平均误差为7.2%和5.8%。在热泵系统中引入SGC可以使系统制热量平均提高33.7%,系统COP平均提高35%。
The present study aims to investigate the performance a novel CO2heat pump system designed for electrical vehicle with Series Gas Cooler (SGC) configuration. A numerical model is developed, and experiments in both Air Conditioning (AC) and Heat Pump (HP) mode are performed to validate this model. Based on the validated model, the impacts of ambient temperature, discharge pressure and degree of superheat on the system are discussed. Additionally, a comparison between conventional CO2system and the novel SGC heat pump system is carried out using the developed model. The model can predict system capacity and COP with average errors of 5.1% and 6.0% in AC mode, and average errors of 7.2% and 5.8% are achieved in HP mode. The introduction of SGC into the heat pump system can bring an average increase by 33.7% for the system heating capacity, and an average increase by 35% is achieved for the system COP.
