THE INFLUENCE OF AN ARCHITECTURAL DESIGN ALTERNATIVE(TRANSOMS) ON INDOOR AIR ENVIRONMENT INCONVENTIONAL KITCHENS IN TAIWAN

摘要

This study investigates indoor air environment via the flow fields, temperature fields and aircontaminants (carbon monoxide) distributions in conventional residential kitchens, and looksfor effective methods to solve those problems through natural ventilation techniques.Numerical simulations of the physical problem under consideration have been performed viaa finite volume method for solving the governing equations and boundary conditions. It isobvious that location of accumulation of air contaminants is highly relevant to the location ofgas fires, and realizing the dominant flow pattern will be successful in eliminating aircontaminants, An architectural design alternative, utilizing transoms, is then proposed toimprove indoor air environment in kitchens.
