Performance comparison demonstration unit of architectural glass

摘要

PROBLEM TO BE SOLVED: To provide performance comparative demonstration apparatus for building glass, which applies heat and cold air to the space with a plurality of building glasses on its wall surface and demonstrates insulation efficiency and condensation status of the building glasses, to make the performance easy to understand.;SOLUTION: In this performance comparative demonstration apparatus 20, three sheets of partition board 23 are set up at equal intervals on an innermost section of a box 21, containing an aperture 22 to form small spaces 24; glass samples are attached to one surface of each small space; temperature sensors 25 are protrusively-mounted on the bottom face of each small space 24, respectively; thermal sources 26 are arranged on the top face of each small space 24, respectively; glass 22b is inserted and installed in the front side of the aperture 22 to form sealed cold air space 28; coolant 29 consisting of solid dry ice is located upward of the above cold air space 28 so as to feed cold air downward via a net 29a; and temperature indicators 27, which provide digital display of temperature values detected by each temperature sensor 25, are attached to the positions of each small space 24 in front of the box 21, respectively.;COPYRIGHT: (C)2007,JPO&INPIT
