Résumé

Developments in phase change slurry (PCS) applied to residential buildings cooling are presented. These have been devised for grid-interactive load-shifting and PV self-consumption aimed at diurnal load-shifting of heat pump air condition for space cooling loads. Two separate concepts decoupling heat exchange and heat storage capacities and eliminating mechanical scraping of heat exchangers are being investigated: PCM supercooling-crystallization (PCM-SCrys) and PCM emulsion (PCM-E) slurry systems. Both PCS concepts have been developed for space cooling loads in a residential fan coil installation, therefore needing to supply 7-12 °C cooling water via heat exchange. For PCM-SCrys, a non-eutectic, 39 %mass mixture of NaCHO2-water was found to have stable supercooling, suitable crystallization kinetics and ≥18 kWh m-3 net capacity. PCM-E developments resulted in a blend of 30 %mass organic paraffin with surfactant/nucleation promoter to obtain a stable emulsion with 4.4 K supercooling, 500 mPa s viscosity and 17 kWh m-3 net capacity.
