The tombs of the Pharonic kings in "valley of the kings", Thebes, Egypt are famous for their unique wall paintings and structure. KV62, King Tutankhamen tomb, is the most famous because of the treasures it held intact for over three thousand years. The burial chamber is decorated with scenes from the Opening of the Mouth ritual, Book of the Dead, and representations of the king with various deities. The current status of the tomb is very critical as pink stain and black fungus spots have spread over decorated walls due to excessive moisture content in the air. Visitors’ activities led to extra moisture production inside the tomb, this would naturally lead to more  pink spots and fungus activities. For this purpose and in pursue of restoration operation it was suggested to design and install a special ventilation system that would reduce the relative humidity inside the tomb to normally acceptable environment for artifacts. Commercial CFD codes are also used in order to simulate the indoor air conditions, air flow velocities, temperatures and relative humidity patterns. A parametric investigation to select the most suitable airside system design that doesn't affect the archaeological theme of the tomb and that provides lower air velocities around the wall paintings as well as lower air humidity all over the tomb is reported.
