Description
Summary:The risks of the emergent ecological and technical situation as a result of using liquid ammonia as a refrigerating medium in construction in Far Northern regions have been considered. Affective zone modeling/simulation during ammonia ejection into the atmosphere has been built. A model of reaction between ammonia and plastic frozen ground has been suggested. A conclusion of ammonia monitoring in the atmosphere and advisability/expediency of liquid ammonia substitution on alternative refrigerating medium, Freon-22, has been drawn Рассмотрены риски возникновения чрезвычайных экологических и технических ситуаций при авариях, связанных с использованием жидкого аммиака в качестве хладагента при строительстве в зонах вечной мерзлоты. Проведено моделирование зоны поражения при выбросах аммиака в атмосферу. Предложена модель взаимодействия аммиака с пластично мерзлыми грунтами. Сделан вывод о необходимости мониторинга аммиака в атмосферном воздухе и целесообразности замены жидкого аммиака на альтернативный хладагент - хладон-22.
