- Abstract
- ONLY ABSTRACT IN ENGLISH The performance of three different types, commercially available, residential sprinklers and a high-pressure water mist system nozzle was evaluated in a living room scenario. The sprinklers were of the recessed pendent, concealed and horizontal sidewall type. A living room was constructed using wood studs and ceiling joists. The ceiling height of the living room was either 2,5 m or 5,0 m. The living room was attached to a smaller bedroom. The ceiling surface and ceiling gas temperatures were measured. The tests with the sprinklers were conducted at a nominal discharge density of either 2,05 mm/min (0,05 gpm/ft2), 4,1 mm/min (0,1 gpm/ft2) or 6,1 mm/min (0,15 gpm/ft2), respectively. The results indicate that residential sprinklers generally will reduce the severity of the fire compared to the non-sprinklered case. However, the performance of the tested residential sprinklers was very dependent on the type of sprinkler and the way the fire was initiated.
