A novel combination of the Thermally Activated Cooling System (TABS) and Glass Fiber Reinforced Gypsum (GFRG) was investigated for various water flow path configurations. The proposed combination is called a Thermally Activated Glass Fiber Reinforced Gypsum (TAGFRG) system. In a warm and humid climate, the 3.5 m x 3.5 m x 3.5 m experiment room is built with a TAGFRG roof. The parameters required for thermal comfort index calculation, i.e., surface and air temperature, indoor humidity, and air velocity, are continuously monitored and recorded at an interval of 1 minute using a data acquisition system. The configuration of the various water flow paths is clearly described in the article. The data repository contains the hourly averaged measured data as well as the thermal comfort indices that were calculated.


Steps to reproduce

Using the data acquisition system, the surface and air temperatures of the indoors and outdoors, the relative humidity of the air, and the temperature of the water supply are all measured every minute. The numbers and positions of thermocouples are listed in an Excel spreadsheet. After collecting the data, a Matlab code was used to figure out the thermal comfort parameters, and the results were then averaged over one hour. The Matlab output for each case was saved in the Excel sheets.
