PURPOSE:To collect and accumulate solar heat very efficiently by a system wherein a blower stops and a heat accumulating material starts radiation of heat when the temperature in a heat-collecting air chamber lowers to a set temperature of a thermostat, and a heat exchanger absorbs the radiated heat and the heat of the heat-collecting air which rises spontaneously from a solar heat air collector to said air chamber. CONSTITUTION:When sunrays are weak, the temperature in a heat-collecting air chamber 8 lowers, and when said temperature falls down to a set temperature of a thermostat 17, a blower 16 stops operation. Consequently the circulation of air is stopped and simultaneously a heat accumulating material 13 starts the radiation of heat. A heat exchanger 10 absorbs this heat and makes it accumulated in a heat-accumulating chamber 21 through a circulating-water pipe 19. Moreover, a solar heat air collector 2 can catch even weak sunrays such as those obtained in intermittent sunshine and through diffusion. Therefore, when the heated air is formed in the heat collector 2, it rises spontaneously through a heat-collecting air rising channel 7 to heat the heat-exchanger 10 via the air chamber 8. |
