Latent heat thermal storage offers a flexible service to members of district grid as the stored can be used reduce morning peak demand, limiting consequences for production facilities. This work investigates optimized design latent reactor, integrated in an existing building supplied by heating, demand-side management applications. The reactor was designed tube bundle exchanger which commercial-grade paraffin phase change material. variables that maximized use Phase Change Material were pitches and fin heights. integration with energy system required control prediction its state charge power output. These parameters are usually evaluated through 3D numerical dynamic simulations require large computational effort, is beyond capability basic microcontroller systems. A simplified parametric model has been overcome this issue. load-tracking algorithm embedded program. able 62 kWh from 6:00 9:00 a.m. Decreasing pitch 95 mm 82 led +34% increase PCM. Similar results obtained when height increased 20 32 mm. investigation suggest proposed could applied similar buildings fed heating network
