Transcritical CO2 heat pumping systems.

Author(s) : STENSTADVOLD K., NEKSÅ P.

Summary

The paper outlines key developments of transcritical CO2 systems, mainly focusing on projects where SINTEF and Shecco have been or are involved. CO2 as refrigerant in heat pumping systems has gained interest due to its environmental and safety advantages. The paper reviews applications where transcritical CO2 systems have been introduced in the market and applications where developments are ongoing. These include heat pump water heaters, heat pumps for space heating, and mobile air conditioning and heat pump systems. Both technology and market information is presented. Where applicable, comparison to alternative system technology will be made. Initially, a brief summary of environmental issues and an introduction to the particulars of CO2 as a refrigerant is given, before the status and trends within selected areas of the technology are discussed. It is shown that CO2 is a viable alternative refrigerant for all these application areas.
