PROBLEM TO BE SOLVED: To provide a ventilation resistor for cold areas capable of preventing incoming cold air from being directly hitting a part of a human body in a cold area, introducing outside air with low pressure losses, and forming comfortable circulation flow indoors by mixing outside air with warm air staying in an upper part of an indoor space by the heating.;SOLUTION: The ventilation resistor comprises a disk-like receiving seat 12 having an inlet 12a which is fitted to an opening part 2 in a wall 1 to allow outside air to flow into a center, and a resistor cover 14 which is attachably/detachably fitted to the receiving seat to cover a front side of the inlet with a space therebetween. The resistor cover 14 has a curved inner surface 14a to deflect the direction of outside air 3 flowing in from the inlet upwardly with low pressure losses, and an outlet 14b to allow the outside air to flow out upwardly with low pressure losses.;COPYRIGHT: (C)2004,JPO&NCIPI
