3. Description of the project
Project "Development of bituminous products formulated with solid-solid phase
change materials for improving the building energy efficiency" (SSbuildENERGY),
PID2023-149701OA-I00, funded by MCIN/AEI/10.13039/501100011033 (Spanish Ministry
of Science,Innovation and Universities) and ERDF "A way of making Europe" under
the 2023 Knowledge Generation projects call. This project is led from the
University of Huelva and developed at Center for Research in Chemical Products
and Process Technology (Pro2TecS). The general objective of this project is to
study the formulation and processing of novel energy-efficient building
materials with enhanced rheological and thermal energy storage characteristics
formulated with solid-solid phase change materials.

4. Description of the dataset
In this research the feasibility of Thermal Energy Storage (TES) materials to be
applied in solar domestic hot water (DHW) collectors was evaluated. These TES
materials are composed of bitumen and different concentrations of
pentaglycerine, which act as supporting engineering material with high solar
radiation absorptivity and
solid-to-solid phase change material, respectively. These materials exhibit
excellent mechanical and thermal properties that make them promising TES
materials for improving energy efficiency in solar DHW production.

METHODOLOGY
--------------------------
1. Methodology
Thermogravimetric analysis (TGA) tests were conducted in a TA Q- 50 (TA
Instruments, USA).Differential Scanning Calorimetry (DSC) was performed with a
Q- 250 DSC (TA Instruments, USA). Viscous flow measurements were performed in a
controlled-strain ARES rheometer (Rheometric Scientific, USA) using a smooth
plate-and-plate geometry (25 mm diameter and 2 mm gap). The thermal
conductivity, at different temperatures, was measured using the non-destructive
Transient Hot-Bridge (THB) technique by a THB 100 device from Linseis GmbH
(Germany).
