Simulating the Effects of HVAC Induced Air Flow from Slot Diffusers on Detector Response

摘要

Airflow due to the heating, ventilating and air conditioning (HVAC) system can significantly modify the flow of smoke along the ceiling and must be taken into design of systems contain very little quantitative information concerning the impact of airflow produced by HVAC systems. This project describes the results of a series of numerical simulations of smoke movement in response to HVAC flows resulting from slot diffusers, slot returns and rectangular returns. The computer model calculated activation time throughout the fire driven flow field.
