IIR documentSummary
Carbon dioxide is very effective as the refrigerant for instantaneous hot water heating, because the low incoming water temperature provides the opportunity to achieve low gas cooler outlet temperatures and hence efficient operation. In a district heating system this is not possible because the water return temperature is typically in the range 60 to 70°C. This paper presents an alternative design for district heating systems which uses carbon dioxide as the primary refrigerant and offers efficiencies above the figures achieved by typical R-134a systems.
