Low temperature heat storage with phase change materials

The Manufacture of Microencapsulated Thermal Energy Storage Compounds Suitable for Smart Textile

“…The PCMs, having a phase change temperature between -10 and 80°C, can be used for encapsulation (Jahns). Furthermore, according Lane, over 200 phase change materials, with a melting point from 10 to 90°C, are suitable to be encapsulated (Lane, 1980). Thus, among all the potential PCMs used to be microencapsulated in a polyester resin, the best results were obtained by using CaCl 2 .6H 2 O.…”

Overview of Basic Solid–Liquid PCMs Used in Building Envelopes—Packaging Methods, Encapsulation, and Thermal Enhancement

“…Inclusion of 3-5 wt% SAP was found to be an effective thickener for most of these salt hydrates. For the low hydrate inorganic salts (CH 3 COONa · 3H 2 O, Na 2 S 2 O a · 5H 2 O), adding small amounts of 2-4 wt% of carboxymethyl cellulose (CMC) 13 stabilized the salt hydrate (Lane 1980(Lane , 1983. In research study performed by Gok et al (2009), Glauber's salt (Na 2 SO 4 10H 2 O) was successfully stabilized with different concentrations of polyacrylamide and gelatin gels, which were used to prevent incongruent melting.…”

Densities of nitrate hydrates used as phase change materials

“…At the same time, temperature of the solution was recorded by a thermometer with the accuracy of 0.1 °C. The density was calculated as follows: (Dincer and Rosen, 2002;Lane, 1980;Naumann and Emons, 1989) 36.4 (Abhat, 1983;Have et al, 1993) Tab. 3.…”
