Application and summary of fresh water-source heat pump system in Chengdu Jinjiangchuangyi Science and Technology Building

The project is a demonstration project of renewable energy application in buildings, adopting a fresh water-source heat pump system for cooling, heating and domestic hot water supply. To realize the system energy efficiency ratio over 3.0 both in winter and summer, considering the water quality of the water source, adopts the scheme of the water entering the heat pump unit directly. By selecting anti-corrosion units and installing rubber-ball cleaning devices, guarantees the stability of system operation.
