PCT No. PCT/IB94/00038 Sec. 371 Date Nov. 14, 1994 Sec. 102(e) Date Nov. 14, 1994 PCT Filed Mar. 11, 1994 PCT Pub. No. WO94/20752 PCT Pub. Date Sep. 15, 1994A solar chimney assembly including a chimney (1) for receiving fluid from a solar heat collector (6, 7), and a turbine (2) driven by the fluid. The solar heat collector, which increases the moisture content and the temperature of the air flowing past the turbine, has an evaporative area (6) and a non-evaporative area (7). The non-evaporative area acts as a heat absorbing area and has a first cover (8) which inhibits evaporation of a heat-absorbing liquid retained therein. The evaporative area has a second cover (4) connected to the chimney and arranged to contain vapor evaporating from a liquid in the evaporative area. The assembly is constructed to transfer thermal energy from the liquid of the non-evaporative area to liquid of the evaporative area, for high efficiency operation. |
