Development and evaluation of an R–744 evaporator model
(North-West University, 2013)
In recent years carbon dioxide (CO2, R-744) has moved to the foreground as an environmentally friendly alternative to commonly used CFCs and HFCs, which are being phased out due to its high ozone depleting and global warming ...
Theoretical and experimental analysis of supercritical carbon dioxide cooling
With on-going developments in the field of trans-critical carbon dioxide (R-744) vapour compression cycles, a need to effectively describe the heat transfer of supercritical carbon dioxide for application in larger diameter ...
A methodology for the performance characterisation of a variable speed CO2 compressor
(North-West University (South Africa), Potchefstroom Campus, 2018)
Heat pump cycles have a vast range of industrial applications. A refrigerant withdraws heat from a reservoir, transferring it to another fluid. In order to design and sufficiently size these cycles, accurate operating ...
