Vapor Injected Scroll Compressors

Click here to purchase

Vapor injection has been available on large commercial screw and multistage centrifugal compressors, but not on small hermetic compressors. The recent introduction of vapor-injected scroll compressors allows the economized refrigeration cycle to be applied with individual small compressors, and achieve the benefits of increased capacity and efficiency. This article describes the economized vapor-injection (EVI) scroll compressor concept, its key components, and the associated performance and application aspects for commercial refrigeration systems.
