Below is a picture showing the evolution of the Airhood from early prototype to final product design. As shown in the figure, the temperature of the monitoring point rises to more than 200C up to 300 seconds when the fire source is present, and then decreases gradually after the temperature rapidly drops to less than 50C up to about 400 seconds after 300 seconds when the fire source disappears. The authors declare no conflicts of interest. Heptane was applied as a combustion material, and the chemical combustion heat was set to 41,200 kJ/kg, the CO generation rate 0.010, and the smoke generation rate 0.037, respectively. Figure 11(b) shows the analysis results for fan operating condition, and the generated CO is completely discharged, and the CO density within the space is almost zero.

As shown in the table, the design flowrate is 400 CMM, and the blade diameter is 630 mm. Therefore, it is considered that the utilization of portable smoke exhaust fans that can perform emergency ventilation in the case of fire suppression and rescue operations in houses and general buildings of environment where smoke control equipment is not installed, or its operation is difficult will not only enhance the safety of firefighters during the operations but also prevent job-related firefighter injuries and casualties. Figure 7 shows temperature variations over time with height of opening at the monitoring point of 1m in the lower part for condition where the smoke exhaust fan operates from 420 seconds after 300 seconds when the fire source disappears. In other countries, the European standard EN 12101-3 and U.S. ANSI/ ASHRAE standard 149 present detailed design and performance test standards for smoke exhaust blowers [3] [4] , and studies have been conducted regarding the impact of these standards and future improvement directions [5] .

Based on the results, the following conclusions were made. Not the cheapest, but would buy again if had to do over! fan portable ventilation flexible duct ducting inch blower fans site globalindustrial feet rollover zoom It can be found that as the height of the opening increases, the temperature at the monitoring point becomes lower, and the temperature in the space is almost close to the outdoor temperature of 20C at 600 seconds at the opening height ranging from 1.5 to 2.0 m. Figure 15. Daily news and analysis about the food tech revolution. This fan did everything I expected to it to do. As shown in the figure, the smoke density at the monitoring point is greatly reduced as CO is smoothly discharged when the smoke exhaust fan operates as in the case of the smoke density. | In this study, the numerical model of the portable smoke exhaust fan was derived from the building in which a fire occurred, and the analysis on the smoke and toxic gas exhaust effects was performed. On the other hand, if the smoke exhaust fan operates after the fire source disappears, smoke is directly exhausted to the outside due to the operation of the smoke exhaust fan, and the smoke density within the space drops sharply in all opening height conditions, thereby getting close to zero.

ShyuanYa have met the worldwide standards and have qualified by ISO 9001:2015 and CQC quality system. Meanwhile, the related industry has been manufacturing smoke exhaust blowers and evaluating their performance according to its own standards and thus failed to secure effective and reliable performance data, and technology developments for improving the performance of smoke exhaust blowers have not yet been achieved. According to some assessments, the pressurization fans of air supply type which are currently used in fire departments have a limitation in discharging smoke quickly in the space for staging fire suppression operations inside the building. Especially in the event of a fire in houses and general buildings where smoke control equipment is not installed, there is a need for a portable smoke control system for efficiently discharging smoke in the buildings in order to efficiently perform fire suppression operations and ensure the safety of firefighters. Servicing should be carried out once a year, Get all the info. PVE800 (a) Fan-off condition; (b) Fan-on condition.
Fume extractors are an important part of workers health and safety by filtering and extracting potentially harmful fumes, gases and or dust particulates from the space. Figure 8(a) shows the smoke density contours in 200 seconds after the fire, which is a stage where the fire grows, when the smoke density at the top is about 4.0 10-4 kg/m3.
