Autor/autori: Mihail-Dan N. STAICOVICI


Abstract: Recent research has shown that the effectiveness of the classic mechanical vapor compression (MVC) heat pumping can be highly improved, if the technologies, published by the author, of recovering the compressor discharge gas superheat and converting it either in useful mechanical work (see the Thermal-to-Work Recovery Compression (TWRC) method) or in useful effect of cooling or heating (see the Thermal-to-Thermal Recovery Compression (TTRC) method), were applied. Despite the methods high COP advantage, these are confronted with the high discharge gas temperature major drawback. The Hybrid Compression (HC) technology, proposed in this paper, is capable to avoid TWRC and TTRC disadvantage and some of classic MVC cooling and heating problems. The HC technology cycles are presented and modelled and cooling and heating model results are given, showing that HC can compete with TWRC and TTRC methods effectiveness and bring additional useful technological features in the classic MVC heat pumping, as well. Key words: freeze drying, deep cooling, heating, effectiveness, absorption, mechanical vapor compression, Osenbr├╝ck cycle, hybrid compression, hybrid absorption, discharge gas temperature, compressor clearance diagram, heat source supply.
