The ageing chamber is ready to test the NRG-Foam panels. 🏁
What does the ageing chamber do? The chamber provides different conditions of heat and frost to emulate the environment to which the panels will be exposed and try to predict their long term utility lifespan. The applied programme is operated in such a way that each climatic cycle consists of, for example, 45 minutes of solar and UV radiation with heating to a temperature of +50 °C 🥵, and 45 minutes of freezing to -20 °C 🥶. The time of each cycle may also be extended or shortened.
Such quick changes in temperature simulate the accelerated ageing of the samples: 100 simulated cycles correspond to about 2️⃣ years of natural weathering (based on literature). The tests are made to check the behaviour of the phase change material embedded in the ultra-light foam-cement composite under heating-cooling cycles.
