PURPOSE:To simplify constitution by eliminating a heat exchanger and to facilitate handling, by a method wherein an outdoor air intake fan and indoor air exhaust fan are provided, and the outdoor air and indoor air are made to ventilate in a crossing state at outlet sides of both the fans so that they are made to exchange their heat. CONSTITUTION:Outdoor air A and indoor air B are blown out into a main body casing 3 by lateral flow fans 9 and 10 as shown by arrows respectively. In this instance, as positions of jets 11a and 16 of fans 9 and 10 are arranged by shifting them in axial directions of the fans mutually, spouting air A and B are passing through the casing 3 by meeting at about right angles within the casing 3 with each other without coming into collision with each other. At the time of this crossing heat is exchanged between both the air A and B, the outdoor air A is accumulated and discharged inside 1 of a room through a discharge opening 6 and the indoor air B is dissipated and discharged outside E a room through a discharge opening 8. |
