Infinite R PCM maintains comfortable building temperatures while eliminating the need for HVAC.
Previous WinWerks' blog posts described what infinite R thermal massing material does; its financial and sustainability benefits (2-4 year paybacks, savings to investment ratios of 3-6), how it can efficiently regulate internal building temperature in a variety of ways (thermal shock absorber), and how long it lasts (guarantee of 25 years and lasts longer). But the BIG question often asked is: how do we know that it works? How do we predict and measure its efficacy? WinWerks' next few blog posts will explore the predictive calculation models and why Infinite R works so well.
Dr. Maria Telkes - MIT scientist and technologist that pioneered phase change material research.
As background, the scientific basis for Infinite R comes from a 1940s technology application by MIT Dr. Maria Telkes built on 1880s physics and chemistry research conducted by Edward Morse. However, PCMs also occur naturally, the most obvious being ice, which absorbs energy every time it melts into water. The science of PCMs are based on the idea of latent heat, an inherent characteristic of all solids, liquids, and gases. The latent heat of a material is the heat required for a substance to change phase - solid to liquid, liquid to gas, etc. While there is no change in the temperature of the substance as it changes phase, a huge amount of energy is either absorbed or released due to a difference in intermolecular energy. This is the concept behind all PCM, but different materials/formulations affect how much energy can be absorbed or released. In modern building applications, BASF paraffin, BioPCMs, palm oil-based, and Infinite R are the most common PCMs used in walls, ceilings, roofs, and around windows to regulate heat fluctuations.
Infinite R uses an inorganic, sustainable salt hydrate material, patented in 1999 after 40 years of research on similar substances. With Infinite R, the optimal hydrate transition (melt point) degree matches the environment in which it's placed. In comparison to PCMs made with organic materials, Infinite R requires more energy to transition from solid to liquid and thus, can store more heat. Furthermore, Infinite R has been formulated for different climates so that it can insulate or remove heat depending on the usual outside temperatures and what is most comfortable. Overall, Infinite R applications successfully stabilize building temperatures because of science and research that are proven in the real world through various third party measurements and verification studies.
