Thermo Regulating interior Coating featuring Phase Change Materials (PCM) 1 GUIDE 1 - Phase Change Material (PCM), a new challenge in construction – What is a Phase Change Material ? – What are the applications ? – PCM a new challenge in construction 2 - ENERCIEL, First thermo-regulating coating – Presentation – Benefits 2 What is a Phase Change Material ? Phase Change Material or PCM have the capacity to store and release large amounts of energy. This energy is called latent heat. Each PCM has a specific melting and crystallization temperature and a specific latent heat storage capacity. The most commun PCM on earth is Water… 3 What is a Micro encapsulated Phase Change Material ? WINCO PCM Microcapsules PCM Microscopic view (X1000) What is a Phase Change Material ? SOLID / LIQUID Phase Change: Temperature rise above 21°C (70°F) Heat Storage phase : indoor temperature stabilizes to 21°C (70°F) LIQUID / SOLID Phase Change: Temperature fall below 21°C (70°F) Heat release phase : indoor temperature stabilizes to 21°C (70°F) WINCO PCM Technology is the result of mor than 8 years of Research and Development 6 What are the applications ? • Construction • Textile • Food packaging industry • Medical packaging industry • Automobile, Transportation 7 A new challenge in construction Observation : Today’s construction are increasingly using modern lightweight building methods with highly insulating materials Consequences : The Lack of thermal storage mass lead to negative impact on indoor climates. Impact comfort and energy use for cooling/heating Axis of enhancement : Find a solution to increase thermal mass without increasing building total mass. And use it as a benefit for comfort and energy conservation 8 Why this Technology ? Source : Fraunhofer Center for Sustainable Energy Systems.
