R290作为替代制冷剂的火灾危险性的研究进展

Development of Fire Risk Study by Using R290 as Alternative Refrigerant

目前空调器普遍使用的制冷剂是R22,它对臭氧层有很大的破坏作用。R290具有良好的环保性能,但是易燃易爆的特点是其使用的最大阻碍。介绍了国内外对于使用R290制冷剂的空调器泄漏研究以及火灾危险性评估的研究,总结了国内外相关标准中对可燃制冷剂使用的相关规定。

At present R22 is widely used as air-conditioner refrigerant,but it damages the ozone layer.R290 has a good environmental performance,but its explosive characteristics is a major obstacle to its use.The domestic and foreign research advances of leakage and fire risk assessment of R290 of air-conditioner are introduced in this article.Relevant provisions for the use of flammable refrigerants in relevant standards at home and abroad are summarized and future research is also prospected.
