Impact of a thermoelectric subcooler heat exchanger on a carbon dioxide transcritical refrigeration facility

To improve the performance of vapour compression refrigeration cycles, inclusion a thermoelectric subcooler for low-medium power units has been focus recent studies due to its robustness, compactness and simplicity operation. In systems, it demonstrated that heat exchangers used in hot cold side modules have critical impact system. This influence not yet studied subcooling systems cycles. work, first time, evaluates subcooler, included transcritical carbon dioxide cycle, have, cycle. The is quantified terms of: optimum working conditions, coefficient cooling capacity. results show that, through an optimization improvements on using this technology are boosted from 11.96 14.75 % upgrade capacity system rises 21.4 26.3 %. Moreover, gas-cooler pressure reduced voltage supplied increases.
