氨作为制冷剂,由于其绿色、环保、对臭氧损耗值(ODP)为零,全球变暖潜能值(GWP)为零,且制冷效率高,价格低廉,在全世界范围内得到广泛应用。应该说目前采用氨做制冷剂是主流,今后仍将是主要制冷剂。由于氨有毒,且易燃易爆,在使用中如果管理不当容易发生泄漏,一旦发生事故,将对国家财产和人民生命造成重大损失。本文配合国务院安委会《关于深入开展涉氨制冷企业液氨使用专项治理的通知》,结合国内涉氨制冷企业目前存在的问题,提出一些对应措施。
Ammonia as a refrigerant is widely used all over the world because of its green and environmental protection, zero ODP, zero global warming potential (GWP), high refrigeration efficiency and low cost. It should be said that the current use of ammonia refrigerant is the mainstream, the future will remain the main refrigerant. As ammonia is toxic and inflammable and explosive, if it is mishandled and easily leaked in use, once an accident occurs, it will cause heavy losses to state property and people’s lives. In this paper, with the Notice of the Security Committee of the State Council on Further Carrying Out the Special Treatment of Liquid Ammonia Using in Ammonia-Ammonia Refrigeration Enterprises, some countermeasures are put forward in light of the existing problems in ammonia-related refrigeration enterprises in China.
