Heat release characteristics of landscape water body applied to surface-water ground-source heat pump systems

Taking a real project in Wuhan as example in which the landscape water body with the fountain is the heat sink of the surface-water ground-source heat pump system, simulates and analyses the influence of water intake and drain positions and water intake volume on the water intake temperature, heat carrying capacity and water temperature recoverability. Makes some suggestions to ensure the surface-water ground-source heat pump system stable and reliable operation for long term, such as increasing the superficial area of the water body, decreasing the water intake volume, adopting intermittent operation mode and optimizing the water intake and drain positions.
