摘要

Frequent high-temperature weather has led to a surge in air conditioning (AC) usage, exacerbating urban climate deterioration. Previous studies lack a systematic examination of climate-adaptive AC application characteristics. This study proposes a modified Weather Research and Forecasting (WRF) model by incorporating common AC types and validates its accuracy. Using this modified model, the impact of different AC configurations on the urban microclimate is investigated. Results show that AC heat emissions increase urban air temperature by approximately 0.3 °C, alter relative humidity by −1.0% to 2.4%, and elevate urban boundary layer height by 30–40 m. Decentralized air source heat pumps and household ACs cause similar climatic effects, while for centralized systems, air source heat pumps induce stronger thermal disturbances than water-cooled chillers. In addition, ground-installed systems intensify near-surface warming by approximately 0.5 °C compared to rooftop installations. The findings suggest that climate-friendly AC strategies are characterized by a combination of high-efficiency decentralized household ACs and rooftop centralized water-cooled systems. The methodology and insights provide a reference framework for quantitatively evaluating climate-adaptive AC applications in other urban contexts.
