by using 20~27oC temperature difference between warm surface
seawater at surface and cold deep seawater. OTEC is environmentfriendly
and semi-permanent energy sources because its heat source is
seawater warmed by the sun and no incineration,and no CO2 emission
can be achieved.
In this paper, it is focused on the cycle that is removed the regenerator,
the absorber, and the diffuser from conventional Kalina cycle, and is
returned the liquid working fluid separated with the separator to the
inlet of the evaporator. The cycle was called R-cycle. It is compared Ncycle
with a conventional Karina cycle by the numerical simulation.
Two computational methods are used the program that is not treated the
heat transfer performance of each heat exchanger, and other program
that is treat the heat transfer performance of each heat exchanger and
the condition of heat source. As a result, a past Kalina cycle was more
efficient even though which calculation was used.抄録:英語フィールド
