Study on data augmentation with physics-informed generative adversarial networks and the extrapolation performance of COP prediction for chillers

•PI-WGAN framework improves COP prediction under sparse data and distribution shift.•Vendi Score and Mahalanobis distance quantify data diversity and extrapolation risk.•Physics-informed samples enhance physical consistency and statistical reliability.•MAPE reduced from 41.2 % to 136.3 % to 4.97 %–1...
