Studies on the Use of ISO 7730 in Romanian Companies
No full textThis paper aims to identify how the ISO 7730 Standard is perceived by manufacturing companies in Romanian industry. This paper aims to integrate the details of the ISO 7730 Standard into the research related to the level of comfort in manufacturing companies with high heat emissions. Furthermore, we hope to identify how the indices provided in the ISO 7730 Standard can influence the productivity and quality indicators in production

Get PDFWith the trends of comfort modelling moving more towards the application of Adaptive Models, the influences of several parameters as used in the traditional ISO7730 standard are therefore non-existent. The proposed work considers the conventional ISO 7730 standard as conservative in its calculation; however extremely useful, in cases where actual measurements of spaces are considered (ISO 7730, 1994). Measurements from a comfort cart built according to ASHRAE-55 standards (ANSI/ASHRAE 55, 2005) together with thermal imaging temperatures are combined. In doing so, an ISO 7730 thermal comfort assessment applying the CBE – ASHRAE 55-2004 Comfort Tool allows for changes in the environment to be examined for improved comfort (Huizenga, 2006; Tyler et al, 2017). Results for two cases in a severe Darwin climate yield an improved PPD by 2.5-2.7 times when implementing extremely low- energy measures

A larger statistical basis and a wider application area of a re-derived PPD equation in the (NEN-)EN-ISO 7730 model
No full textThis paper has the objective to initiate a discussion on potential improvements or extension of the validity of the original equation of the Predicted Percentage of Dissatisfied (PPD), according to (NEN-)EN-ISO 7730. This paper is to be regarded as a supplement to a paper on a re-derivation of the PMV equation in the Fanger model (Roelofsen, Jansen, and Vink 2021). In practice, in scientific research it regularly appears that the PMV (Predicted Mean Vote), and by extension the PPD, are applied outside the range based on which the PMV and the PPD equation are derived. In practice, this can occur, for example, in the evaluation of the measurement or calculation of temperature exceedances in a room, for sedentary activities. As it turns out, a PMV equation with an application of −3 to 3, for at least sedentary activities, would be useful in the different fields of study. For that reason, Roelofsen has adapted the PMV equation in the (NEN-)EN-ISO model. But to what extent should the PPD equation also be adjusted? After all, the PPD is also derived from and limited to a PMV of −2 to 2, according to (NEN-)EN-ISO 7730.Emerging MaterialsMaterials and Manufacturin
