Experimental Study on the Characteristics of Thermal Sensitivity for Fusible Alloy Type Sprinkler Head
The sprinkler head is a component of the sprinkler system intended to discharge water for automatic detection and extinguishment of fires. On this study, thermal characteristic values affecting the sensitivity of the fusible alloy type sprinkler head were obtained and analyzed under heated air stream condition which had constant temperature and velocity. The experiment was carried out under the forced convection condition with both the conductive heat loss considered and neglected. The thermal characteristic values of the sprinkler head were obtained in accordance with the material and shape of the heat responsive element and the conditions of the main body.
Key Words: Fire Protection, Sprinkler Head, Thermal Sensitivity, Response Time Index, Conduction Parameter
