摘要
湖水源热泵利用水体的水温在系统排热或排冷工况下将发生动态变化,水体的水温变化超过水体所能承受的排热或排冷量时,将导致湖水源热泵系统运行不正常甚至瘫痪。在二维初始水温模型的基础上,利用质量和能量方程,建立了水源热泵系统利用水体水温变化的动态模型。通过水流方程与温度方程藕合求解得到水体在带负荷状况下的水温变化模型方程。该计算方法不仅可以为湖水源热泵系统的可行性研究奠定理论基础,也可作为计算利用水体最大热承载能力的前期研究基础。
The temperature of water used for surface water source heat pump（WSHP） could make dynamic changes in the condition of heat or cold rejection. When the water temperature is over the amount of heat or cold rejection that water can take, WSHP system will run irregularly even paralyze. Based on two- dimensional model of the initial water temperature, dynamic model of water used for WSHP was proposed with mass equation and energy equation. And with flow equation coupled with temperature equation, the equation of water temperature changes in load was obtained.
