Two research projects of Prof. Hongxing YANG, our RISE member are awarded by Hong Kong Productivity Council
We are pleased to announce that two research projects which are led by Prof. Hongxing YANG, our RISE member are recognised as 2022年度深港環境創新優秀項目, which represent their efforts on green technologies application.
Hong Kong Productivity Council partner with Shenzhen Environmental Science Society (深圳市環境科學學會) and Shenzhen Academy of Environmental Sciences (深圳市環境科學研究院), co-organised the 2022年深港生態環境科技創新交流活動.It aims at providing a platform for environmental industry, scientific research institutes and academia between Hong Kong and Shenzhen, to collaborate conduct innovative green technologies researches and exchange their valuable ideas. Kindly find the below project information for your reference.
Project Title: Development of Inline Hydropower Harvesting Systems for application in urban water supply pipelines 為智管網供能的自適應水力發電裝置
Investigators: Prof. Yang Hongxing, Dr Wang Qiliang, Mr Yao Yao, Mr Shen Zhicheng
Abstract:
Supported by the Innovation and Technology Fund, though collaborations with Water Supplies Department (WSD) of the Hong Kong SAR Government since 2012, four generations of the Inline Hydropower Harvesting Systems (IHHS) have been developed for power supply to the Water Intelligent Network (WIN) of local water supply pipelines for data monitoring purpose. The system includes a novel turbine, a generator and a smart controller. About 15-25 W electric power can be produced at water flow speed of 1.5 m/s in normal water pipelines. A demonstration system on a real water pipeline has been operated for more than 18 months. Significant labour and other maintenance costs can be saved if this novel system can be used throughout the WIN system in the future. Reliable power supply to the WIN system also means reliable and continuous data recording and transmission from the WIN system for protecting the local water supply pipelines.
Project Title: A Novel Indirect Evaporative Cooler for Enhanced Energy Recovery in Central Air-Conditioning Systems 高效能量回收間接蒸發冷卻器
Investigators: Prof. Yang Hongxing, Mr Shi Wenchao, Ms Ma Xiaochen
Abstract:
This novel Indirect Evaporative (IEC) technology can be used to recover energy from central air-conditioning systems for precooling fresh air by capturing the cooling potential of exhaust air from indoor space enhanced by water evaporation in the wet channels of its heat exchanger. A large wet-bulb depression of the secondary air can be achieved by using the exhaust air to evaporate sprayed water in wet channels, which facilitates the primary air-cooling process in dry channels for fresh air supply to buildings. This technology is especially developed for hot and humid regions like Hong Kong where the IEC can achieve sensible and latent heat recovery because of possible condensation deriving from highly humid fresh air. About 17-35% of the energy consumption for fresh air supply to commercial and public buildings can be saved depending on the operation hours and amount of fresh air supply of a central air-conditioning system.
RISE sincerely congratulate to Prof. Yang and his research team!
