Even though water (R718) is one of the oldest
refrigerants, state of the art technology is
required to use water as a refrigerant in
compression refrigeration plants with turbo
compressors. In regard to using water as a
refrigerant, some specific features complicate its
application in refrigeration plants with turbo
compressors. Because the cycle works at very low
pressure, the volumetric cooling capacity of water
vapor is very low. Hence, huge volume flows have to
be compressed with relatively high pressure ratios.
Therefore, the use of water as a refrigerant,
compared to...
