IIR documentSummary
The experimental results from the prototype show that CO2 is very well suited as working fluid for tap water heating. The energy consumption is reduced by more than 75% when hot tap water is required at 60 deg C, using ambient air as heat source. Due to the high volumetric efficiency and the good heat transfer characteristics of CO2, it should be possible to produce compact and cost efficient systems.
