The invention discloses a transcritical CO2 automobile air conditioner thermal management system and an optimal charging amount calibration method thereof. An air-conditioning system comprises a compressor, a gas cooler, a heat regenerator, a mass flow meter, a throttling valve, an evaporator and a liquid storage device. According to the method, firstly, judgment basis parameters selected by the judgment method are pointed out, then, the specific implementation working conditions of the judgment method are pointed out, and finally, the specific implementation steps of the judgment method for the charging amount are specifically provided. According to the method, the judgment of the system charging amount is comprehensive and considered comprehensively, poor system performance and even partdamage caused by improper charging amount are avoided, unnecessary loss is reduced, and meanwhile energy saving is facilitated.
本发明公开了一种跨临界CO汽车空调热管理系统及其最佳充注量标定方法,空调系统包括压缩机、气体冷却器、回热器、质量流量计、节流阀、蒸发器、储液器。本发明首先指出了该判定方法的选择的判断依据参数,然后本发明指出了判断方法的具体实施工况,最后本发明具体提出了充注量的判定方法的具体实施步骤。本发明对系统充注量的判定综合且考虑全面,避免了由于充注量的不合适导致的系统性能的不佳甚至是部件的损坏,减少不必要的损失同时有利于节约能源。
