It is studied the collected heat by collectors fixed on the outside wall of balconies when the shape and direction of balconies, and inclination angle of collectors are changed. Total heat collected by three walls of the rectangle balcony toward southeast or southwest is more than the one collected under other conditions. Total heat collected by rectangle balcony toward south would be increased when the inclination angles β of collectors are reduced. As β=70°, and the collectors were installed only on the south wall, to make water temperature above 60 °C in 150 L tank, extra energy needed is equivalent to 46.5 kg/a standard coal; if collectors were installed outside three walls of balcony, extra energy is not needed. |
