Abstract

Abstract: Aiming at the problem of insulation performance degradation caused by vacuum maintenance failure of vacuum insulation panels (VIP) in the field of building energy conservation under long-term service, this paper investigated in-situ monitoring of vacuum maintenance status for VIP and dynamic control of building energy conservation. Built a multimodal vacuum status monitoring platform to real-time collect key parameters of VIP core material vacuum maintenance status in situ; combining the improved particle filter algorithm, a vacuum attenuation dynamic model was constructed to dynamically predict the degradation trajectory of VIP's vacuum maintenance ability under different harsh climate conditions; developed a dynamic optimization system for building envelope structures based on deep reinforcement learning, coupled with BIM models and real-time vacuum monitoring data, to adaptively adjust the operating parameters of the building energy management system.The result shows that the research realizes the in-situ, continuous and accurate monitoring of the key parameters of VIP vacuum maintenance state in service. The vacuum decay prediction model provides a new method for evaluating the long-term service reliability of VIP. The optimization system based on real-time perception of vacuum state can effectively compensate the adiabatic loss caused by vacuum attenuation and significantly reduce building energy consumption.
