The purpose of this paper is to redesign, compare, and study using bi-directional shape memory alloy spring to compensate for the shortcomings of the existing fire damper performance. Through the spring constant measurement experiment, using the difference in force between the coil spring and the shape memory alloy spring, the damper closes when the set temperature is reached, and opens again when the temperature is lowered. In addition, the internal structure was redesigned through smoke leakage experiments. As a result, semi-permanent usable dampers were modeled.
