MRT definition: : Strålande temperatur - Mean Radiant

Mean radiant temperature listed as Trmrt. As a result of the changing climate with trends of rising temperatures and increasing extreme heat events, urban planners and city officials have recently taken a great interest in improving the cl The mean radiant temperature makes possible to observe radiant interchange between man and environment. Non-contact two-dimensional area temperature measurement The mean radiant temperature was calculated from the globe temperature using Equation 9 (forced convection) of Annex B of ISO 7726 (ISO 1998).

Radiant temperature has a greater influence than air temperature on how we lose or gain heat to the environment. where θ c is the operative temperature (°C), θ ai is the indoor air temperature (°C), θ r is the mean radiant temperature (°C), H is the ratio h c h c + h r, and (1 − H) is the ratio h r h c + h r. The mean radiant temperature (m.r.t.) is usually assessed as the radiation received at a point (or by a small sphere), butit is clearly important to knowhow adequately this parameterdescribes the heat load on a man, for in the presence ofhot surfaces his shape and orientation mayhave It consists of three air temperature sensors (located at different heights) and a mean radiant temperature (MRT) globe positioned at about the height of a seated person.

Given both the growing importance the outdoor thermal environment of cities and the role played by these tools, reporting on their performance is of high importance.The aim of this study is to assess the ability of several recently emerged or updated microclimate models to reproduce mean radiant temperature (Tmrt) in a complex urban setting. Mean Radiant Temperatures (MRT) for a subject exposed to solar radiation in different positions of the environment and, with an hourly time step, for a whole year, have been calculated by means of Many translated example sentences containing "mean radiant temperature" – German-English dictionary and search engine for German translations.
