Summary
The latter fluorinated greenhouse gases regulations are reinforcing the use of CO2 as working fluid in commercial refrigerating plants due to its ultra-low global warming potential and its natural condition. Nevertheless, the transcritical operation at high ambient temperatures provokes a decrement on their coefficient of performance promoting further investigation on this topic to optimize their behavior. This research combines thermoelectric cooling with a CO2 vapor compression facility, providing a subcooling at the exit of the gascooler that increases the COP up to the 9.9 % .
