Abstract:
1. A heat exchange type ventilator comprising: an exhaust-air coupling section communicating with outdoors via a duct for forming an exhaust-air channel and coupled to a lateral side of the ventilator; a supply-air coupling section communicating with outdoors via a duct for forming a supply-air channel and coupled to a lateral side of the ventilator; and a ventilating unit having a box-like shape and including an exhaust-air outlet for sucking stale interior air through an opening disposed on an underside of the ventilating unit and a supply-air inlet for drawing fresh outside air into a room, the ventilating unit comprising: wherein the cut-off damper cuts off the flow of the supply-air based on a signal issued from the supply-air temperature sensing means, and the motor reduces a speed of the exhaust-air fan based on the signal issued from the supply-air temperature sensing means to reduce a volume of the exhaust air exhausted by the exhaust-air fan.
