Thermal Comfort in High MRT Environments: Case Study of a Commercial Single Store Glazed Building

摘要：

This paper presents a design method to define the settings of HVAC systems in order to provide thermal comfort in high mean radiant temperature (MRT) environments in hot climates.The method,firstly,discuss the use of simplified thermal load calculation methods,in face of the specificities of the theme.Then,dynamic heat,air and moisture envelope simulations are performed in order to define the surfaces internal temperatures.The distribution system,including terminal sizing and positioning,flow rate and temperature,is defined based on CFD simulations.A thermo-physiological model,including short wave radiation,is considered to evaluate the thermal comfort conditions under the sun and in the shadow,during summer and winter days.A commercial single store glazed building in S(a)o Paulo,Brazil,is used as a case study.
