CO2 as refrigerant for heat pump and refrigerator

From an ecological and safety-relevant point of view carbon dioxide is an almost ideal refrigerant. This project information of the „BINE News Service" informs about a combined expansion compression machine developed at the Technical University Dresden, with which, due to the thermodynamic characteristics, high inlet temperatures can be reached as are necessary for conventional heating systems in old buildings. So far heat pumps are suitable only for low temperature systems such as under-floor heatings.
