Welcome to the web site for
Sunoba Pty Ltd. This web site contains details
of new heat engines that generate power through evaporative cooling of hot
air at reduced pressure. The principal
target applications are ·
passive solar thermal
power generation ·
booster for open-cycle gas turbines In simple terms, heat engines
turn heat energy into useful work. They
are used to generate electricity or provide mechanical power for vehicles and
equipment. Examples include Otto or
Diesel engines for vehicles, Brayton engines for jet aeroplanes, and Rankine steam turbines to generate electricity. The thermodynamic
cycle for the evaporation engine involves hot dry air +
water → power + cooled moist air This cycle was confirmed in an
experimental evaporation engine that was tested successfully in mid
2008. The evaporation engine can be
built in either continuous-flow or piston-in-cylinder form. A related technology is the condensation heat pump, which is
based on condensation of water vapour in air at reduced pressure and has the
opposite thermodynamic cycle to the evaporation engine. Heat pumps are used to increase the
temperature of the immediate environment; the
reverse-cycle air conditioner is a common example. Please follow the links to find
out more. |
