Phase-change materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting and freezing. PCM allows for the over-night cool energy to be stored in Tube-Ice cells (charge period). This storage process allows the PCM to absorb the internal and solar heat gains throughout the day, hence producing a free passive-cooling system. It is in lieu of this that PCM offers a truly zero-carbon energy-free cooling solution that provides numerous benefits — including a highly retro-fittable design that can be applied to any new or existing building. Furthermore, it requires minimal to zero maintenance.
