Energy improvements of CO2 transcritical refrigeration cycles using dedicated mechanical subcooling
Elsevier (2015-07)In this work the possibilities of enhancing the energy performance of CO2 transcritical refrigeration systems using a dedicated mechanical subcooling cycle are analysed theoretically. Using simplified models of the cycles, ... -
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 evaluation of a CO2 transcritical refrigeration plant with dedicated mechanical subcooling
Elsevier (2016-09)CO2 transcritical refrigeration cycles require optimization to reach the performance of conventional solutions at high ambient temperatures. Theoretical studies demonstrated that the combination of a transcritical cycle ... -
Improving efficiency of transcritical CO2 cycles through a magnetic refrigeration subcooling system
Elsevier (2022-04-20)Subcooling methods for transcritical CO2 plants are being studied in order to improve the behaviour of these systems in hot climates, where basic configurations are not competitive enough. To achieve important improvements ... -
Performance assessment of an experimental CO2 transcritical refrigeration plant working with a thermoelectric subcooler in combination with an internal heat exchanger
Elsevier (2022-07-19)Regulations in the refrigeration sector are forcing the transition to low global warming potential fluids such as carbon dioxide in order to decrease direct greenhouse gases emissions. Several technologies have arisen over ...
