CC-75-500: Reducing Weight in Future Satellites
potential refrigerants were examined closely. In order to comply with the high energy requirements of NLR, low losses had to be guaranteed. This is only possible with low pressure values, which is why fluids like ammonium and CO2 could not be used. This led to selection of Isopentane (R601a). Calculations showed that the gas pressure, for the required heating, had to be increased from 1.76 to 7.2, which equals a pressure ratio of 4.1. To achieve this, a system with three subsequent turbo compressors... (read more)
