HYBRID COMPRESSION HEAT PUMPING CYCLES BASED PLANTS

摘要

Recent research has shown that the effectiveness of conventional Mechanical Vapor Compression (MVC)heat pumping may be greatly improved. This may be done by implementing technologies recently publishedby the author. They consist of recovering the compressor discharge gas superheat and converting it eitherinto useful mechanical work (see the Thermal-to-Work Recovery Compression (TWRC) method) or inuseful effect of cooling or heating (see the Thermal-to-Thermal Recovery Compression (TTRC) method).Despite the advantage of the resulting high COP, a major drawback is the high discharge gas temperature.The Hybrid Compression (HC) technology proposed in this paper has the potential to avoid TWRC andTTRC disadvantage and some of classic MVC cooling and heating problems. HC technology cycles arepresented and modelled and cooling and heating model results are given. These show that HC can competeeffectively with TWRC and TTRC methods and bring additional useful technological features in the classicMVC heat pumping, as well.
