CRYOGENIC DISPLAY HALL

PURPOSE:To make arctic clothes unnecessary for spectators and to make artificial landscape free from deformation by radiant heat emitted from human bodies by providing a spectators' passage, encircled by thermal insulating walls having transparent thermal insulating members, in a cryogenic space containing the artificial landscape consisting of exhibits made by cryogenic condensation. CONSTITUTION:A cryogenic display hall is constructed of a cryogenic space 1 containing an artificial landscape consisting of exhibits 2 made by cryogenic condensation, and a spectators' passage 5 encircled by thermal insulating walls 3 having transparent thermal insulating members 4. The cryogenic space 1 is thermically isolated from the outside space by a thermal insulating top wall 11, thermal insulating side walls 12 and a thermal insulating floor 13. Therefore, a spectator 6 can look at the exhibits 2 in the cryogenic space 1 and the artificial landscape consisting of such exhibits 2 without the need for an arctic cloth.
