碩士 === 吳鳳科技大學 === 消防研究所 === 104 === In practice, Fan-Coil units always are installed as air-conditioning equipments in many offices or hospital rooms to reach the set conditions of the air conditioning in Taiwan.In recent years, Standards forEstablishment of Health CareFacilities" and Standards forEstablishment of Hospitalsformulatedby the Ministry of Health and Welfarehave amended the Article No. 3: It’s necessary for building air-conditioning equipment to install the power switch interlocking device with fire detectors to automatically cut off the function when fire detected. There are no clear specification in the regulation of Building Technical Regulationsformulatedby the Construction Department and Standard for Installation of Fire Safety Equipments Based on Use and Occupancy formulatedby the Fire Department to control the air conditioning system when fire occured, neitherto requirehow the interlocking of fire detection equipment.FDS simulation software was used in this study to analyze the effectiveness of thermal zone, as well as to observe the impact relative to smoke on the wall height in LR room.The relation of smoke diffusion and air-conditioning system did not shut down the blower has also been investigated. The air-conditioning did not shut down the blower and smoke diffusion of the association has also been explored.The results showed that the higher height of the partition wall of LR room is better.If the barrier set to the top of the ceiling, a significant block effect to smoke and heat were generated in the fire scene.From the simulation results, it may not cause harm to another compartmentwhen the blower is not closed. Positive manner to the heat generated by the combustion of fire room, by the door extrusion discharge. Heat generated by the combustion in fire room can be discharged to outside through positive pressure mode.
