摘要

跨临界CO

热泵空调系统具有良好的低温制热能力，其运行过程中的动态参数变化对乘员热舒适性的影响重大。为研究乘员舱舒适性以及跨临界CO

热泵空调系统参数动态变化的耦合规律，基于一维仿真软件GT-Suite和三维CFD软件STAR-CCM+搭建了联合仿真模型，建立了乘员舱温度场与热泵空调系统的结构化关联关系，综合分析了热泵空调系统运行过程中车厢动态升/降温特性。结果显示：乘员舱热环境温度分布较不均匀，有必要采用加权PMV（平均热感觉指数）评价乘员舱非均匀热环境。在多PID控制的跨临界CO

汽车热泵空调系统中，使用基于加权PMV舒适度模型的控制方法能够保持系统目标参数的调控稳定。在制冷模式43 ℃环境温度工况下，该控制方法能够降低9.4%的压缩机功耗；在制热模式-10 ℃环境温度工况下，该方法能够降低17.9%的压缩机功耗，该控制方法能够在满足热舒适的前提下降低系统压缩机功耗，有助于提升新能源车续航里程。

Abstract

A transcritical CO

heat-pump air-conditioning system has effective heating performance at low temperatures

and the variation of dynamic parameters during operation significantly affects the thermal comfort inside the passenger cabin. To study the comfort of the passenger compartment and the coupling law of the dynamic changes in the parameters of the transcritical CO

heat-pump air-conditioning system

a joint simulation model was built based on the one-dimensional simulation software GT-Suite and the three-dimensional computational fluid dynamics (CFD) software STAR-CCM+. The three-dimensional cabin model can provide accurate real-time state parameters of the supply and return air for a one-dimensional simulation system of heat-pump air conditioners. The results show that the temperature distribution of the thermal environment of the passenger compartment is relatively non-uniform

necessitating the application of the weighted predicted mean vote (PMV) to evaluate this non-uniformity. In a multi-PID control transcritical CO

automobile heat pump air conditioning system

a control method based on the weighted PMV comfort model can maintain the regulation and stability of the system's target parameters. Under ambient temperature conditions of 43 ℃ in cooling mode

the control method can reduce the compressor's power consumption by 9.4%. At an ambient temperature of -10 ℃ in heating mode

this method can reduce compressor's the power consumption by 17.9%. This control method can reduce the power consumption of the system compressor while satisfying comfort requirements

constituting a highly efficient energy-saving strategy.
