PURPOSE:To make a simple structure of a heat collection control device by a method wherein each of a rated value of fan between an air collector, room and a heat accumulation tank, and a solar cell capacity is set in response to each of the operating levels. CONSTITUTION:An operating voltage V10 of a first fan 4 for heating a room 2 is lower than an operating voltage V20 of a second fan 5 for a heat collection tank 3, electric current values I0 and I0' of each of power supply solar cells 6 and 7 are set such that I0 is higher than that of the solar cell and each of the releasing voltages Voc and Voc' are set such that Voc is lower than Voc'. With this arrangement, when the second fan 5 is kept turned off, the heating operation is performed through an air collector, first fan 4, room 2 and air collector 1 in sequence, amount of solar heat is increased, and when an output characteristic of the solar cell 7 is exceeded over a rated voltage Vo' of fan 5, the fan 5 is turned on and for the air circulation the collector 1 fan 4 fan 5 heat collection tank 3 and the collector are also applied for performing a simultaneous heat accumulation and then the constitution of the device can be simplified. |
