美国谷轮压缩机公司Warren L,Beeton和HungM.Pham在美国供暖制冷空调工程学会杂志上发表文章,介绍一种新型制冷节能技术——带经济器的中间充气涡旋压缩机。文章指出,目前大型制冷用螺杆压缩机和多级离心压缩机都采用中间充气来实现经济器循环.而小型全封闭压缩机则尚无此种技术。最 American Copeland Compressors Warren L, Beeton and HungM.Pham published an article in the American Journal of Refrigeration and Air-Conditioning Engineering, introducing a new type of refrigeration-saving technology, an intermediate-charge gas scroll compressor with an economizer. The article pointed out that the current large-scale refrigeration screw compressors and multistage centrifugal compressors are used to achieve intermediate gas charge cycle, while the small fully enclosed compressor is not such a technology. most
