Active Cooling Systems with PCM

CrodaTherm™ bio-based phase change materials can be used within a room or building cooling system in place of standard air conditioning. At night, as with the passive approach, the PCM is “charged” as it solidifies by cool night air or from a chiller system operating on low-cost night time electricity. During the day, room or building air is forced into contact with the PCM and is cooled as heat is transferred from the air to the PCM, which gradually melts to a liquid state. This provides cooling using a fraction of the energy (and CO₂ emissions) from running an air conditioning system, saving money.
