The results also found that when the distance between the gas in the 0.2 ~ 0.3m maximum mass flow rate; when the separation distance less than 0.1m, the import area had no effect on the mass flow rate; when the separation distance increased to O. 3 ~ 0.5m, if the area increases, the gas flow rate increases. Meanwhile, the flow rate was increased with the increase of surface temperature. 4 Conclusion (1) solar heating and cooling can take advantage of solar technology exchange radiation than conventional heating and cooling systems more energy efficient. However, in order to ensure reliable operation of the system, often need additional boilers or electric heating devices, which to some extent, an increase of the initial equipment investment; (2) Trombe wall and vertical-type roof solar chimney collector, ventilation rate the size of its air channels the ratio of the width and height of the chimney is related to both the chimney there is an optimal aspect ratio problem; inclined roof solar chimney collector plate with the ventilation air channel width increases,<a href="http://www.oakleybriller.com" target="_blank" class="postlink">oakley norge</a>, there is no chimney the relationship between the best aspect ratio; paper analyzes the impact of 3 Although the typical size of solar chimney ventilation rate of the major factors, but for different wall materials (such as brick, concrete, insulation materials) the size of the impact of ventilation rate has been no discussion, which will be reserved for future follow-up studies; (3) the use of solar energy from the current situation, there is a common problem is the inefficient use of solar energy, only improve the efficiency of solar energy in order to eventually promote the application of solar energy.
