av M Lööf · 2019 — När CO2 används som köldmedium kallas det R744, och några av dess egenskaper är att International Journal of Low-Carbon Technologies. 2 (3): 225-249.

R744 (CO 2) is a leading option for environmental reasons, and it can be a winner for power consumption as developments of component technology and application methods continue to reveal potential performance gains. Good experience has been gained with different system configurations over many years, particularly in central and northern Europe.

R744 co2 technology

R744 systems work transcritical when the gas cooler exit temperature is above 31 °C (88 °F). HFC systems always work subcritical because the condensing temperature never exceeds the critical temperature (e.g., 101 °C / 214 °F in the case of R134a). The R744 E-Compressor is a prototype that is still under optimization development. It has a smaller displacement due to a larger volumetric cooling/heating capacity of CO2. Visteon Spearheads R744 Climate Technology for Conventional and Hybrid Vehicles KERPEN, GERMANY (Sept. 7, 2007) - Visteon Corp.'s latest automotive thermal management solution is an application-ready CO2-based R744 climate system that consumes up to 25 percent less incremental fuel compared to conventional R134a systems. CO2 (aka r744) is a pretty awesome refrigerant that is ideal for electric cars such as the ID3. The benifits of CO2/r744 is widely known and include: CO2/r744 is a Global Warming Potential of just 1. This is much lower than almost every other type of refrigerant used or proposed.
