The invention discloses a heating-ventilating dual-purpose
solar air collector which comprises a cover plate, a
metal outer frame, an inner frame, an absorber plate, an outer sealing plate, a
temperature control switch, a draught fan, an upper air inlet and a lower air inlet. An
air layer is arranged between the cover plate and the absorber plate of the collector; the outer sealing plate is movably connected to the top of the
metal outer frame; the inner frame is fixed in the
metal outer frame; a lateral
insulation layer is arranged between the metal outer frame and the inner frame; the draught fan and the
temperature control switch are separately arranged on the inner side of the upper air inlet in a pluggable manner; the draught fan and the
temperature control switch are arranged in series to be electrically connected; the upper air inlet and the lower air inlet are separately connected with an upper
indoor air inlet shield and a lower
indoor air inlet shield; and a heat-isolating plate is further arranged on the inner side of the draught
fan in a pluggable manner. Through serial connection between the built-in draught fan and the temperature
control switch, start or stop of the draught fan is controlled through temperature, so that the heating-ventilating dual-purpose
solar air collector is reliable in operation and safe and energy-saving. If the heating-ventilating dual-purpose
solar air collector is used for heating in winter, only the upper and lower
indoor air inlet shields require to be opened. If the heating-ventilating dual-purpose solar air collector is used for ventilating in summer, only the outer sealing plate and the lower indoor air inlet shield require to be opened.
