地表水地源热泵用景观水体散热特性研究
Heat release characteristics of landscape water body applied to surface-water ground-source heat pump systems
摘要：
以利用带喷泉的景观水体作为地表水地源热泵热汇的武汉市某实际工程为例，模拟分析了取排水口位置和取水量对景观水体取水口温度、热承载能力、水温恢复能力的影响。建议增大水域表面积，减小取水量，采用间歇运行方式，优化取排水口位置以保证地源热泵系统较长时间稳定可靠的运行。
Abstract：
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.
