Experimental main task

Overall system evaluation Heat exchangers evaluation Compressor losses and oil cooler capacity System control Presentationsmaterial EFFSYS 2 dagen 2009-12-14

Conclusions

Field measurements performed Simulation models for several systems built Test rig built and running CO2 systems have potential with: -floating condensing and recovering heat from de-superheating -connected to heat pump at the condenser loop Presentationsmaterial EFFSYS 2 dagen 2009-12-14
