本文提出了一种新的方法，实时优化的集成过冷跨临界CO2热泵热水器使用相量ESC。与传统的抖动解调ESC相比，相量ESC在优化效率上有所提高。在Dymola环境下建立了热泵系统的动态仿真模型。从一个单一的相量ESC放电压力，我们提出了调整ESC参数，如抖动信号频率，这显着缩短了几乎一半的搜索过程的实用指南。多变量相量ESC的有效性和适应性在各种运行条件下，包括时变干扰，如环境温度。仿真结果表明，相量ESC的性能优于标准策略和经典ESC。
This article presents a novel approach to real-time optimization of integrated subcooling transcritical CO2heat pump water heater using the phasor ESC. Compared to the traditional dither-demodulation ESC, the phasor ESC shows improvements in optimization efficiency. A dynamic model of the heat pump system with high fidelity was developed in Dymola. Starting from a single phasor ESC for discharge pressure, we proposed practical guidelines for tuning the ESC parameters, such as the dither signal frequency, which significantly shortens the searching process by almost half. The effectiveness and adaptability of the multi-variable phasor ESC were demonstrated under various operating conditions, including time-varying disturbances such as ambient temperature. Simulation results showed that the phasor ESC outperforms both standard strategies and classic ESC in terms of performance.
