The application of renewable energy technologies, such as the earth-air heat exchanger (EAHE), is quite conducive to reducing the energy consumption of buildings. However, the heat transfer process of traditional EAHE may greatly change the soil temperature, which hinders the system from fully exerting its thermal performance. Based on the features of high energy density and stable output temperature...
For solar heating systems, adding phase change material (PCM) can significantly increase the thermal storage capacity. This paper proposes a system using a PCM thermal storage unit cascadely combined with a water tank and configures a composite PCM suitable for the system. This study investigates the impact of this system configuration on the system efficiency while developing a matching principle...
As the survivable mapping is critical in IP-over-wavelength-division-multiplexing (WDM) network to guarantee the restorability of IP layer, provisioning survivability in network with dynamic traffic is essential. However, survivable mapping problem for dynamic traffic shows more complexity than that for static traffic: 1) How to guarantee a survivable mapping since the lightpath is established and...
An energy efficiency scheme based on the coordination of management and control is proposed to reduce the power consumption in multi-domain WSON. Experiments are conducted on the energy efficient multi-domain WSON testbed (EEMWT) to assess the performance of the scheme.
