This paper presents a numerical simulation based on computational fluid dynamics (CFD) method on the enhancement of natural ventilation in an industrial workshop with heat source induced by solar chimney (SC). Four types of SC were designed to attach to the top and southern roof of the workshop. Realizable k-ε turbulent model and DO (discrete ordinate) radiation model were used to calculate the air...
Task conditioning aims to provide each occupant with personalized clean air direct to the breathing zone. Microenvironment of a typical office workplace consisting of different task air conditioning system, such as CMP (computer monitor panel), MP (movable panel), horizontal desk grill (HDG) and vertical desk grill (VDG) are studied by numerical simulation. Numerical simulation by k-epsiv 3-D turbulent...
The indoor environmental quality (IEQ) is examined from the prospect of an occupantpsilas acceptance in four aspects: thermal comfort, indoor air quality, noise level and illumination level. This paper proposed a fuzzy synthetic evaluation with changeable weights to approximate the overall IEQ acceptance of a certain indoor environment. Different evaluation factors have different influences in FSE,...
