摘要

本文介绍了一种用于暖通空调和制冷的鼠笼式三相异步电机的性能和效率的改进方法。最近，这些机器已由V/F控制的变频器驱动，从而降低了暖通空调系统的总体成本，同时提高了其整体效率。鼓风机和泵的负载转矩与转子转速成正比。这可以通过优化通量的大小来进一步改善。本文提出了用磁场减弱法优化磁通以提高整机效率的方法。

Efficiency Improvement of Three- Phase Induction Motors in Refrigeration and HVAC Applications

This paper presents the method for improving the performance and efficiency of a three-phase asynchronous ma-chine with squirrel cage architecture used in HVAC applications and refrigeration. Recently, these machines have been driven by V/F controlled VFDs, which led to decreasing the overall cost of the HVAC system and increasing its overall efficiency simulta-neously. Load torque in the blower and pumps is proportional to the rotor speed. This can be improved further by optimizing the flux's magnitude. This work presents the optimization of flux using the field weakening method to increase the machine's overall efficiency.
