CO2 system for European Vending Machine was optimized to have the same pull down performance as baseline R134a system without changing fan, fan motor, electric light and physical dimension of the installation room.
Energy Consumption of CO2 system is 10% less than that of R134a systemat 32 degree C / 65 % RH.

Ambient Temperature (degree C)
Energy Consumption (kWh/day)
10 CO2 systems and 2 R134a systems were installed to the field. Their energy consumption and ambient temperature were measured by DAQ system.
Energy Consumption of CO2 system is 17% less than that of R134a system in the field test during the summer season.

World Average Temperature World Average Temperature
In many regions, the dominated ambient temperatures are less than 24 degree C.
70% of world average temperature is less than 24 degree C and only 5% of world average temperature is more than 32 degree C.

Cost Analysis Cost Analysis CO2 Compressor Conventional Rotary Compressor for AC
Parts and materials used for CO2 compressor are almost same as those for conventional HFC or HCFC rotary compressor for AC.
If the production quantity of CO2 compressors is closer to that of the conventional rotary compressors for AC, the incremental cost of CO2 compressor will ultimately become the difference of material usage.
