  • With regard to smoke control system, the design guidelines of smoke exhaust for accommodation and smoke control for evacuation stairs and vestibule has been proposed domestically, but after reviewing the applicability to modern buildings that tend to be larger, higher and complex, a smoke control system according to domestic design guidelines might have difficulty in securing the safety from smoke in a fire. Therefore, it is necessary to adopt the performance-based design of a smoke control system that can enhance the safety and integrate the smoke control functions and design depending on the characteristics of fire and building structure in the case of fire in a large, high-rise, and complex building. This study analyzed the domestic design guidelines of a smoke control system and this paper proposes the part requiring improvement, and examines the legal system and guidelines on performance-based design of smoke control system in foreign countries.

  • The fact that the smoke hinders evacuation and fire-fighting activities as well as becomes the major cause of life casualty emphasizes the importance of smoke control system. As one of the fire safety standards designed to secure the smoke safety, NFSC501A (Design Guide for Smoke Control System of Special Evacuation Stairwell and Lobby) has been proposed, preventing smoke from penetrating into the smoke-free escape route by raising the pressure of the smoke control zone higher than fire area. For model building of 20 stories, pressurization system was designed according to standard and pressure field of compartments in whole building induced by pressurization system was analyzed using the network model.

  • In this study, fire simualtion was performed to examine the necessity of smoke control system in the tunnel fire. The heat release rate was set to 5 MW and 20MW, and the visibility was measured at 1.8 m, which is the breathing limit, when there is no jet fan. Through this, it was confirmed that 5 MW did not affect the visibility even without the jet fan, and in the case of 20 MW, a jet fan was required to secure the visibility. The visibility was measured at the same location by installing the jet fan, and the simulation was performed by reducing the design volume flow rate of 8.5 m3/s by 80% and 50%, respectively. As a result, it was confirmed that sufficient visibility was secured when the design flow rate and 80% were reduced.

  • This paper presents a network based fire detection system using CAN, in order to evaluate feasibility of home automation protocol for smart home. In general, because a traditional fire detection system has an analog transmission method with 4-20mA current, it has several shortcomings such as weakness to noise. Hence, as an alternative to the traditional system, this paper presents the architecture of CAN based fire detection system and the design method of CAN communication network. Also, the performance of the suggested system is evaluated through an experimental testbed. Especially, CAN has several advantages such as low cost and easiness of implementation compared to Ethernet or ARCNET, which are low layer of BACNet. Therefore, if CAN is adopted as low layer of BACNet, the home automation system is implemented more effectively.

  • Over 100 experiments have been conducted at the University of Maryland to evaluate the performance of a water mist fire suppression system for protection of an interstitial space below a raised subfloor. Experiments are conducted as part of an ongoing research effort to compare the fire suppression capabilities of various water mist system designs in a raised subfloor space. Water mist system design parameters considered in the investigation include means of actuation, concentration of water mist required for extinguishment of fires, and delivery mechanisms of water mist within close proximity to the fire. Delivery of the required concentration of water mist within close proximity to the fire is a principal factor governing the adequacy of water mist systems. Two sets of experiments have been conducted to document the performance of water mist system designs. One set is involved in documenting the concentration of water mist as a function of position within the space. The second set of experiments is concerned with the ability of water mist system designs to control fires in the space. One result of the research is the assessment of the ability of a water mist system to control fires at particular locations as a function of water mist density at that location.
