Experimental Analysis and Optimization of an R744 Transcritical Cycle Working with a Mechanical Subcooling System
MDPI (2020-06-19)In the last century, the refrigerant R744 (carbon dioxide) has become an environmentally friendly solution in commercial refrigeration despite its particular issues related to the low critical temperature. The use of ... -
Experimental Assessment of the Internal Heat Exchanger in Vapour Compression Systems With Low GWP Refrigerant R516A
Elsevier (2022)Internal heat exchangers (IHX) are commonly used to improve the energy performance of vapour compression refrigeration cycles. However, the magnitude of the improvement depends on the refrigerant and operational ... -
Experimental enhancement of a CO2 transcritical refrigerating plant including thermoelectric subcooling
Elsevier (2020-09-02)CO2 is an excellent natural refrigerant that can be used in almost any commercial cooling application thanks to its useful range of evaporative temperatures and excellent environmental properties. However, due to its low ... -
Experimental evaluation of a transcritical CO2 refrigeration facility working with an internal heat exchanger and a thermoelectric subcooler: Performance assessment and comparative
Elsevier (2022-08-01)The use of carbon dioxide in transcritical state has become one of the most used solutions to comply with the F-Gas directive and reduce greenhouse gases emissions from refrigeration systems at high ambient temperatures. ... -
New positions for an internal heat exchanger in a CO2 supercritical refrigeration plant. Experimental analysis and energetic evaluation
Elsevier (2014-02)IHX is probably, one of the most commonly alternative used to improve cooling capacity and COP in a CO2 refrigerating plant working in supercritical conditions. The “classical” position at gas-cooler exit has been analyzed ... -
Towards sustainable process heating at 250 °C: Modeling and optimization of an R1336mzz(Z) transcritical High-Temperature heat pump
Elsevier (2024-04-01)Fossil fuel boilers typically produce high-temperature process heating due to the impossibility of current renewable technologies. Vapour compression heat pump systems have been proposed up to 200 °C with subcritical cycles. ...
