EVAPORATIVE-COOLING AND ABSORPTION-HEATING IN AIR GAPS INSULATION POWERED BY HUMIDITY FLUCTUATIONS
Air gap insulation is a common means of providing thermal insulation from the environment. In many cases the air gap is heated by direct or indirect solar radiation, so ventilating this gap has a cooling effect. The invention cools this gap by integrating moisture-absorption material units that harvest water from the air during the night and provide evaporative cooling during the day. Compared to the ambient air, the daily relative humidity fluctuations in the air gap are more extreme, allowing a significant cooling effect. Furthermore, during the night, humidity absorption on the absorption unit reduces the risk of condensation within the air gap. Additionally the absorption process generates heat, and by using a controller processes of heating, cooling and dehumidifying can be activated when possible and needed.
