Community energy planning in Shanghai Expo Park: Review and reflection

Reviews the energy planning process in the Park. From the earliest natural gas combined-cycle cogeneration scheme to the later distributed energy system scheme, and to the final option based on a comprehensive system of river watersource heat pump, all these are based on the consideration of maximizing energy system efficiency. For the river water-source heat pump scheme, studies from aspects of cooling load distribution, water temperature estimation of the Huangpu River, energy consumption analysis, the optimum pipework radius of district cooling, the impacts of large-scale river water-source heat pump on the local ecological environment, and operating mode of the river water-source heat pump. And calculates energy saving and carbon emission mitigation benefits of the scheme.
