Jonas Schönenberger from Frigo Consulting presented the analysis of several CO2 transcritical systems examined in search for an efficiency improvement. CO2 transcritical systems with a parallel compression, an expansion-compression unit or an adsorption chiller deliver desired improvement and prove to be efficient at high ambient temperature. The CO2 system with the adsorption chiller provides 6% energy savings due increased subcooling and additional 6% on energy saving on compression.
