It has a smaller displacement due to a larger volumetric cooling/heating capacity of CO2. The main features of the E-compressor are high discharge temperature (e.g., 150℃ or larger), high discharge pressure (e.g., 12.5 MPa or larger), power consumption (e.g., less than 6 kW), etc. Global manufacturer Danfoss has added its CO2 compressor, valves, pressure controls, controllers and sensors for small commercial applications to R744.com. This is Danfoss’ third product series presented on the platform, after its solutions for R744 commercial and industrial refrigeration.

2013-12-01 · The compressor's efficiency defect of R134a is always higher than that of R744 from a minimum of 17 to a maximum of 32%. With the increase of the evaporating temperature the compression ratio and the mechanical power of the compressor decrease. As a consequence the compressor's efficiency defect decreases. 100 kW R744 Compressor for commercial refrigeration published Nov 18, 2012 - 22 pages Christian Schmälzle's presentation, Obrist Engineering, Market Innovations session, ATMOsphere Europe 2012 The compressors currently used in development by Audi, BMW, DaimlerChrysler and Volkswagen are based on this principle and manufactured by LuK/Sanden. In comparison with the refrigerant R134a, R744 poses considerably more difficult conditions for the compressor as a result of the much higher pressures and the effects on lubricants. These r744 compressor are equipped with modernized technologies to convert air pressure into potential energy and are largely used for industrial processes.
