PLUSS® www.pluss.co.inPhase Change Materials (PCMs) &the three questions10
PLUSS® www.pluss.co.inWhy□ Prolongs the duration at which temperatures(cold/hot)need to be maintained without external source.□ Saves energy□ Saves cost□ Human comfort□ A green concept – reduces pollution□ Ability to shift peak power loads to off-peak hours (astorage device)□ As a back-up for temperature critical applications11
PLUSS® www.pluss.co.inWhat Materials that can store large amount of heat energy inthe form of latent heat Release/absorption of heat at almost constanttemperature Also called Passive cooling materials. Heat Absorption / Release process repeatable over asubstantial number of cycles (~ 3000 or more)13
PLUSS® www.pluss.co.inPCM Characteristics□ Very high Latent Heat Capacity□ Tailorable for specifictemperature requirements□ Easy handling; can be filled in avariety of encapsulations□ Cheap & very stable over longdurations□ Repeatable phase changecycles□ Low / No flammability□ Non Toxic and Noncombustible050100150200250Stone Plastic Wood Water PCMFor T = 15 KPCM’s Latent heat = 225 kJ / kg14
PLUSS® www.pluss.co.inLatent Heat Storage: Components□ PCM suitable for application temperature□ Encapsulation of PCMs□ A heat exchange surface for heat transfer betweenPCM and heat source/sink15
