Several industries like cold storage and ice plants heavily rely on ammonia (NH3) due to its low cost, excellent thermophysical traits, and zero effects on the ozone layer. Despite its widespread use as a refrigerant, the hazardous nature of ammonia remains a significant health concern. Since the industrial revolution, ammonia leakage has led to numerous major accidents, including fire and vapor cloud explosions. This paper reviews the safety issues and the current practices of risk assessment with regard to the industrial ammonia used in refrigeration systems. In addition, previous works related to the risk analysis of ammonia-based industries are reviewed. The majority of ammonia refrigeration system-related works applied the traditional static tools for risk analysis such as fault tree, event tree, and bow-tie that are not suitable to handle common causes of failures or conditional dependencies, which are absolutely significant aspects for a reliable safety assessment. Thus, it is vital to maintain and improve the safety levels of diverse industries using ammonia-based refrigeration systems. Various characteristics of ammonia-based refrigeration systems and their safety issues related to industry, present development, and future trends are comprehensively underscored. This review may act as a guide to develop a better understanding of dealing effectively with the hazards of ammonia-based refrigeration systems and risk assessment, thus enhancing the overall safety of humans and the environment.

“…In this study, we aim to analyze the influence factor of the diffusion of ammonia gas after it leaks from the liquid storage tank. The following conditions are set as the basic assumptions [16][17][18], which are convenient for analyzing the influence of wind speed and leak position on the diffusion:…”

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 place. 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 Olympics. The wind speed, and release location have been varied to investigate their effects on the dispersion profile. Different positions of the leakage points in the ammonia storage tank have been found to lead to different areas affected accordingly. In general, the dangerous region area decreases with an increase in the wind speed. However, when the wind is aligned with the leakage direction, this trend is reverted. The study may offer an effective method to predict the impact of ammonia dispersion and implement the safe operation of such large-scale systems.
