  • 4. Pluss PCM: The timeline4 PLUSS® www.pluss.co.in
  • 5. 5 Phase Change Materials (PCMs) & the three questions PLUSS® www.pluss.co.in
  • 6. Why6 □ Prolongs the duration at which temperatures(cold/hot) need to be maintained without external source. □ A green concept – reduces pollution □ Shift peak loads to off-peak hours (a storage device) □ As a back-up □ Save Energy/Cost PLUSS® www.pluss.co.in
  • 7. How7 PLUSS® www.pluss.co.in
  • 8. Pluss PCM: The range8 Hydrated salts based PCMs are available for the Micro- entire gamut of functional encapsulated PCM temperatures Hydrated Organic Organic salts PCMs PCMs, microcapsules and Form-stable PCMs available in the mid- temperature range Form stable PCMs Wide temperature range: -36 ⁰ C to 89 ⁰C PLUSS® www.pluss.co.in
  • 9. PCM Characteristics9 □ Very high Latent Heat Capacity □ Tailorable for specific 250 temperature requirements 200 □ Easy handling; can be filled in a variety of encapsulations 150 □ Cheap & very stable over long 100 durations 50 □ Repeatable phase change 0 cycles Stone Plastic Wood Water PCM □ Low / No flammability □ Non Toxic and Non For T = 15 K combustible PCM’s Latent heat = 225 kJ / kg PLUSS® www.pluss.co.in
