This paper discusses an estimation method for the radiative heat emitted from hot equipment such as a commercial kitchen range, and a flyer. Radiative heat cannot be captured by local exhaust ventilation systems; therefore, it becomes the heat load of HVAC systems and influences human comfort. The laboratory experiment method for radiative heat is explained in this paper. First, the surface temperature of the equipment and surrounding walls are measured at many points. Then, the view factor between surfaces are simulated numerically. The radiative heat emitted from the equipment to the surroundings is evaluated on the basis of the measured surface temperatures and the simulated view factors. High-temperature surfaces such as the top of a griddle emits a large amount of radiative heat to the ceiling and wall facing it.
