Résumé

The Hybrid Compression (HC), introduced lately (Staicovici, 2015 a, b, c, 2016 a, b, 2017 a, b, c), is one of the most promising technology in ultra-low temperature refrigeration (ULTR) and ultra-high temperature heating (UHTH). This work continues research of ULTR and industrial refrigeration, presenting the HC-SECTOR cycle, a completion of HC technology. A simplified structure of this cycle, consisting of the coupling between an absorption technology section (ATS) and a mechanical vapor compression technology section (MVCTS), is given. Also, its 1st and 2nd principles effectiveness model is shortly presented by a lemma, proved here. Results are given for single-stage NH3-H2O ATS and NH3 MVCTS. As main input data, the evaporator and external sink source temperatures considered are: -75, -70, ..., -45°C, and +27°C, respectively. The main output data are the 1st and 2nd principles refrigeration effectiveness and HC refrigerant relative compressed volume. The results show HC-SECTOR cycle brings important improvements in refrigeration as compared to HC cycles elaborated so far and to MVC, increasing its feasibility, comparatively.
