主 题：Numerical simulation ammonia diffusion leakage location ventilation
摘 要：The use of ammonia in large-scale refrigeration systems(such as those used for a stadium)requires adequate ammonia leakage prevention mechanisms are put in *** the present study,numerical simulations have been conducted to study the dispersion law in the ammonia machinery room of the refrigeration system for the 2022 Beijing Winter *** wind speed,and release location have been varied to investigate their effects on the dispersion *** positions of the leakage points in the ammonia storage tank have been found to lead to different areas affected *** general,the dangerous region area decreases with an increase in the wind ***,when the wind is aligned with the leakage direction,this trend is *** study may offer an effective method to predict the impact of ammonia dispersion and implement the safe operation of such large-scale systems.
