Numerical Analysis of Indoor Thermal Comfort in Large Commercial Kitchen

A large commercial kitchen is a complicated environment with high temperature and high humidity.If there's no effective fresh air supply system,a large amount of cold air is needed to satisfy the requirement of emission,with plenty of electric energy is wasted.In this paper,a large Chinese kitchen is introduced based on the analysis software FLUENT.The PMV-PPD model is adopted to evaluate the thermal comfort of 4 conditions with different air apply ratios.The result show that for this kind of chicken layout,pollutants will be controlled,when the cold air apply ratio is 20%,with the volume of the cold air reduced and energy- saving.The requirement of the thermal comfort will also be met.
