In this paper, the theory of energy conservation o f thermal channel is briefed, and the thermal calculating model of glazing curtain wall with thermal channel is concluded. Then the equation parameters of the the rmal calculating model are ascertained, and the results of calculation and measu rement are introduced too. The temperature on the wall of either outside or ins ide g lazing, the temperature and velocity of air through the thermal channel, and the rate of heat gain in room can be calculated by the calculating model, which may be helpful to correlative engineering calculation.
