| Abstract |
Occurred in 2017, estimated ventilating fans fire is analyzed for fire prevention, training and count measure. In the results, fire place of estimated ventilating fans showed to most restaurant, multiplex available premises and company. Restaurant fire was carelessness fire of charcoal and sparks in cooking, and estimated like an electric leakage, overheat. No one was killed, and physical harm were 5 about 100∼500 million won in estimation of fire station, also factor of mainly ignition was counted: overheat 9, short circuit 4, sparks 2, current leakage 1 in ventilating fans fire. The surface temperature change of the motor according to the installation direction of the ventilator was based on 40° C in new product, and the horizontal installation condition showed a temperature increase rate about 45% faster than the vertical installation. As for the used products, the horizontal installation condition showed a temperature increase rate about 30% faster than the vertical installation condition like the new product. Especially, during horizontal operation, the load was increased by motor, wing, etc., and the operation was started at about RPM of 85% of the rated speed for about 3 minutes. It is considered that the operation method of the ventilating fans switch and the MAP management are measures to prevent the fire hazard. |
