Abstract
An air type solar system of the present invention has a heat-collecting unit for heating air by solar heat, and a blower fan for blowing the air as a heat medium from the heat-collecting unit. The blower fan is of a large scale, which is capable of: blowing the air at a rate of about 100 to 2000 m.sup.3 /hour; and rotating by a direct-current generated from solar cells under normal conditions. In addition, the amount of airflow is confined by an automatic electrical control in winter to adjust the temperature of heat-collected air to an appropriate temperature for heating and humidification. Therefore, the air type solar system of the present invention can be appropriately operated in quest of an effective use of the solar cells while there is no need to use any storage cell. In addition, the air type solar system is capable of controlling the operation of the blower fan that receives electric power supplies mainly from the solar cells such that the temperature of heat-collected air is not too high in summer while it is adjusted within the desired, range in winter.
