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…

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

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
