PURPOSE:To utilize solar heat and the heat of atmosphere efficiently by a method wherein the heat collector is installed so as to keep an air path between wall surface and is divided into upper and lower stages so as to provide the air path between the upper and lower stages. CONSTITUTION:The heat collector 1 is divided into two parts of the upper stage 1a and the lower stage 1b while a gap (air path) 16 is provided between the upper stage 1a and the lower stage 1b. High-temperature air is introduced from the gap 16 between the upper stage of the heat collector 1a and the lower stage of the heat collector 1b, therefore, the temperature of air below the air path 15 may be increased and the heat exchanging rate of the collector may be improved. |
