PURPOSE: To hold balanced air supply and exhaust quantities by providing a duct chamber installed to a heat exchanger, an exhaust suction port, an air supply blow-off port and a wind direction board.
CONSTITUTION: A part of air introduced into a duct chamber 70 from a chamber 1 by way of a ventilation duct 60 is exhausted outdoors by way of exhaust air passages 86 and 87. The remaining air is circulated into the chamber 1 from an indoor blow-off port 64 by way of an air conditioner 5. The supplied air introduced into a duct chamber 70 from an air supply blow-off port 92 by way of a heat exchanger 9 from outdoors is introduced into the chamber 1 from the indoor blow-off port 64 by way of the air conditioner 5. A part of air introduced into the duct chamber 70 is absorbed positively into an exhaust suction port 91 by means of a wind direction board 80 and exhausted. This construction makes it possible to inhibit a reduction in the amount of exhaust air induced by an air flow in the duct chamber 70 and balance the amount of supply air with the amount of exhaust air.
