<p>The present invention relates to a high efficient underfloor distributing device to automatically and proportionally control an air volume in accordance to indoor temperatures. The present invention saves energy by automatically and minutely control an air volume while proportionally controlling a blowing fan and a damper in accordance to the indoor temperatures, and provides a pleasant service environment by enhancing an air flow path. The underfloor distributing device installed in an access floor to supply conditioned air supplied to a lower part of the access floor from an air conditioner into a room comprises: a case having a conditioned air inlet, an indoor air inlet, and an outlet; and a blowing fan installed inside the case to flow the air received through the conditioned air inlet and the indoor air inlet to the outlet. According to the present invention, the underfloor distributing device to automatically and proportionally control an air volume in accordance to the indoor temperatures additionally comprises: a first damper installed in the case to close the conditioned air inlet by a forward rotating motion and the indoor air inlet by a backward rotating motion; and a control unit to proportionally control an inflow rate of the conditioned air and the velocity of the blowing fan in accordance to the indoor temperatures while controlling the opening degree of the conditioned air inlet and the indoor air inlet by controlling the position of the first damper in accordance to the difference between the indoor temperature and a set temperature.</p> |
