摘要
氨具有良好的热物性和传输特性,是CFCs与HCFCs理想的替代工质。本文介绍了当今氨在制冷空调领域应用的新技术,NH3/CO2复叠制冷技术、氨用CO2载冷技术、NH3冷水机组等,另外,本文还从安全可靠、高效、小型化和自动化等方面阐述了氨制冷技术的发展趋势。我国的氨制冷技术的发展较为缓慢,可靠性和先进性与国外差距较大,必须加强氨制冷技术的研发力度,促进我国氨制冷技术的发展。
Ammonia, with excellent thermal- physical properties, is a kind of natural and sustainable refrigerant.The paper introduces some new technology developed recently in application of ammonia such as the cascade refrigeration cycle using NH3/CO2, CO2 as a secondary refrigerant in an ammonia retrigerating systems, and the technology of water chiller using ammonia. Otherwise, the paper discusses the development trends of ammonia refrigeration technology, including safety guarantee, high efficiency, miniaturization and automation.
