Description

This lecture covers the performance of compressors, focusing on isentropic and volumetric efficiency. It explains the relationship between real suction volume and geometric displacement volume. The lecture also discusses the impact of varying operating conditions on heat pumps, the modulation of suction volume and volume ratio, and the use of injected screw and scroll compressors. Various compressor geometries and features are explored, highlighting the advantages of screw compressors for large-scale applications and scrolls for domestic use. Additionally, the lecture presents experimental data on compressor performance under different conditions.
