Technical grade paraffin waxes as phase change materials for cool thermal storage and cool storage systems capital cost estimation

Performance of a free-air cooling system for telecommunications base stations using phase change materials (PCMs): In-situ tests

“…The percent increase in the amount of PCM would depend on the amount of outside cold air and cooling load in TBSs. It should be noted, however, that more PCM will increase the capital cost of this unit [28]. Although the running time under the energy release mode was shorter, the percent time covered by the LHSU was up to 100% (largest) in Kunming and 65% (lowest) in Guangzhou.…”

Energy geo-storage — analysis and geomechanical implications

“…Paraffin compounds are among the most reliable in latent heat storage systems due to their availability, cost, and safeness. They also have a wide range of melting points, are chemically inert (stable below 500 o C), and exhibit volume change upon melting on the order of 10% (Dincer and Rosen, 2011;He and Setterwall, 2002). The latent heat of fusion of paraffins is about L = 200 kJ/ kg ( Fig.…”

Heat transfer enhancement in cool-thermal discharge systems from ice melting with time–velocity variations

“…Cool-thermal storage systems [1][2][3] have been applied for making ice to meet the peak power requirements and cool-thermal discharge systems [4][5][6] have been used to produce chilled air from melting ice for air-conditioning. The applications are increasing because many utility companies offer variable rate structures that encourage energy use during off-peak periods.…”
