A Novel Active–Passive System for Overheating Reduction of Lightweight Buildings
The present research investigates the active–passive system for cooling application. The Phase Change Material (PCM) plates are applied to the internal wall and ceiling of the PCM modified test cell forming an airgap with its original wall and ceiling which is nocturnally ventilated to decrease the PCM solidification time. The Active–Passive System (APS) system was investigated under different daily melting cycle cases (indoor air temperature of 26, 30 and 35 °C) to test the cooling effect of the system and different nighttime solidification cycle cases (inlet air temperature of 15, 16 and 17 °C) and determine the required solidification time. The results show, that during the hottest daily case the indoor air temperatures dropped to up to 5 °C. During the night cases with inlet temperature of 15 and 16 °C and flowrate of 400 m3/h, the PCM plates solidified in 5 h and 14 h, respectively.
