Background: Exposure to high temperatures is common among workers in hot environments and can lead to physiological adverse effects. Heat radiation from hot surfaces and inflamed ways to get the most important heat is the exposure ways of the workers. The aim of this study was to evaluate the effectiveness of control methods of radiant heat in workers exposed in a blast furnace steel industry. ...

Nowadays, efforts are being made to estimate the thermal comfort in vehicles by measuring each environmental parameter air temperature, air humidity, mean radiant temperature, air velocity, human activity and clothing insulation. An optimum level of comfort in the vehicle is obtained only by using an automatic air conditioning and climate control system. The paper focuses on the analysis of the...

Mean Radiant Temperature (MRT) is a critical physical quantity that indicates how human beings experience radiation in their surrounding environment. If taken outdoors, MRT depends on the temperature of the sky, ground, vegetation and surrounding buildings, and is therefore difficult to predict reliably. An additional challenge for designers is that publically available simulation tools do not ...

The objective of this study is to improve the design of hydronic radiant panel systems through the understanding of the thermal performance of panel systems. The scope of this study includes performing experiments using testing facilities and the radiant panel ceiling in the Energy Research House, and developing a theoretical model that can predict heat transfer from a radiant ceiling panel. In...

Many studies have explored outdoor thermal comfort during the last several years, ever since it has been strongly related to human health and well-being. The physiological equivalent temperature (PET) is one of most commonly used indexes. It approved applied within different urban spaces climates. This study a comparative research that importance using mean radiant (Tmrt) in PET assessment by e...

With global warming and the rapid development of urbanization, outdoor thermal environment is deteriorating. More more research focuses on comfort. The globe thermometer method widely used in than half studies, but there a large error compared with six-direction method. In order to explore accuracy results its impact subsequent comfort indicators, this study carried out year-round comparative e...
