One of the most important groups of organic PCMs is paraffin wax. Take paraffin (n -docosane) with a melting temperature of 42–44°C as an example: it has a latent heat of 194.6 kJ/kg and a density of 785 kg/m 3 [6]. The energy density is 42.4 kWh/m 3. Nonparaffin organic PCMs include the fatty acids and glycols.
