HEATING THINICE MODULES SYSTEM SIZING Eight PCM modules can be installed per m2. This allows for up to 0.995 kWh/m2 TES. For installers, it is important that the heating system has the appropriate power. This can be easily estimated using the below: An individual PCM module is known as a ThinICE. They are filled with 1.6 litres of PCM solution which is then triple sealed for maximum security. It is possible to install these modules in the ceiling and other locations as a means of thermal energy storage. It is possible to fill these modules with any of our S-range PCMs, not only S27. Consult our sales team for any custom applications. Q ins = 995.5Wh/m 2 + Q peak x K t A Where: Q ins = heating system power (W/m 2 ) t = charging period available (hrs) Q peak = peak heat load (W) K = diversity factor (usually 0.6) A = area of underfloor heating (m 2 ) EXAMPLE An underfloor heating system is planned for an 25m 2 room. There is an anticipated peak heat load of 1400W and there is a 10 hour charging period available. Using the above, we know that approximately 200 PCM modules could be installed. The heating system power can also be estimated: Q ins = 995.5 + 1400 x 0.6 ≈ 133W/m 2 10 25 [email protected] +44 (0)1733 245511 www.pcmproducts.net INCREASED THERMAL MASS 25
