I have tried this question before but, people pay little attention it seems like.  I know you can modify engines and all that stuff so that they will compress air and all that good stuff, but CAN THEY HANDLE 4500 psi type pressures. &n


above normal room temperature, the compressors discharge the gas above its critical pressure of CO2 (R744) 1070.38 psi (73,8 bar). The condenser then acts as

R744 Hazards. R744 is not flammable, but its high pressures, toxicity at high concentration, and potential for dry ice formation must be taken into account when applying and handling. This post explains some of the hazards and provides very general guidance on reducing them. 1. Asphyxiation. R744 is odorless, heavier than air, and is an asphyxiant.

Finally, various compressor designs are discussed for possible implementation of parallel compression in a R744 MAC or heat pump system. Consistent with the findings in commercial refrigeration, parallel compression holds promise from performance perspective to promote use of R744 technology in warm regions for automotive climate control.

Latest Developments in Compressors & Refrigeration Systems using R744 (CO2) published May 03, 2010 - 23 pages The German specialist for compressors and condensing units Bock held a presentation about the latest developments in compressors The GEA reciprocating compressor range includes 18 models of compressors subdivided into 2 series: GEA Grasso V and GEA Grasso 5HP as reciprocating compressors with focus on high efficient NH3 and CO2 systems for refrigeration and heat pump applications. 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. 2013-12-01 CO2 (R-744) Variable Speed Rotary Compressors from Panasonic help light commercial refrigeration and heat pump manufacturers migrate to environmentally friendly, natural refrigerants.
