  • PCMs and ice slurries: PCMs: two recent applications

    Phase-change materials (PCMs) can provide thermal storage which means that they can absorb thermal energy when they solidify and release it when they melt. This can be very useful to dampen temperature swings. PCMs are usually water-based and are...
