TRANSPARENT STRUCTURE Russian patent published in 2004 - IPC

FIELD: building units, particularly sash pulleys and lamps.

SUBSTANCE: transparent structure comprises case in which at least one frame and at least two transparent members are installed so that closed cavity with air gap is formed in-between. Closed cavity communicates with ambient space by vent channels formed in frame and, if possible, in case. Summary area of vent channels is determined as , where F_ch is summary area of vent channel, V is velocity of air flow passing through above channels, W is summary volume of air gaps, K_p is ventilation rate.

EFFECT: possibility of establishing communication between air gap with ambient atmosphere along with prevention of condensate or hoarfrost deposition in cavity between transparent members, reduction of heat-insulation properties by not more than 5%.
