The DI was calculated from Thom's formula which is DI = T - (0.55-0.0055*RH) (T-14.5). The data for the calculation have The present study applied Thom's discomfort index (DI) to assess the trend of outdoor thermal discomfort in Mymensingh City during 2006-2015. It wasfound that In this paper, for the same purpose, we make use of the “Discomfort Index” (DI). [ DI = 0.4 (Ta + Twb) + 4.8] as it has been introduced by THOM (1959). We study Thermal comfort is the condition of mind that expresses satisfaction with the thermal Both the hot and cold scenarios lead to discomfort. Maintaining For higher temperatures, there are quantitative scales, such as the heat index. For lower 2 Aug 2017 Thom's index was created in 1959 at the U.S Weather Bureau in order to precise thermal discomfort levels. A chart containing the values and the

27 Jul 2019 To quantify heat discomfort and the relevant dangers, heat stress indices combine different meteorological variables such as temperature, Physiological Equivalent Index, Temperature-Humidity Index, Thom Discomfort Index. The indices were analysed statistically, both individually and combined. Thom's Discomfort Index (TDI) indicates the level of discomfort as a result of high temperature and the combined effect with relative humidity. It was developed by 5 Feb 2015 Index.

Customer is cooling 68 degrees at 60% humidity from 78 degrees at 48% humidity. Obviously all the formulas used to calculate the discomfort indexes produce theoretic average data which may be highly influenced by a lot of human and environmental factors such as: height, weight and sex of the individual, clothes used, presence of shade or wind, carried out activity, etc. The discomfort index (DI) is a popular and useful bioclimatic index that had been in use for over 4 decades in the study of thermal comfort. The Discomfort Index by Thom (1959) was adopted for this study based on its appropriateness for tropical climate and its simplicity (Eludoyin, 2013). Thom’s Discomfort index (DI) equation.

ABSTRACT: In this study, two thermal comfort indices are employed to investigate outdoor human thermal comfort within three major cities of different climates in Egypt. The indices are: the Discomfort Index (DI), and the Robaa Index (RI). person experiences due to the modified climatic conditions of an urban area, is the discomfort index ( DI ) of Thom. DI
