为了基于地板辐射供冷利用地埋管地源热泵系统余冷提供初步的计算依据建立了地板辐射供冷传热模型通过数值求解给出了理论计算结果分析了供水温度、室内设计温度、管间距、埋管深度等因素对热流密度的影响。结果表明:基于地板辐射方式利用地埋管换热器地下余冷能够改善夏季室内舒适度提升系统能效比同时在一定程度上减弱地下冷热负荷的不平衡程度。蓄冷量及供冷能力大小与蓄冷体体积、比热容、供冷初始温度、供冷结束温度及冷耗散有关。地埋管区域的换热性能受地下水渗流、热扩散率以及地热换热器的构造形式影响较大。

Abstract:
The floor radiant cooling system is numerically investigated on the basis of the proposed unsteady-state heat transfer model in this study. According to the simulation results, the effects of the various parameters on the heat transfer rates are discussed, such as the water supply temperature, the design temperature of indoor air, the pipe space and the burial depth. The simulation results demonstrate that the floor radiant cooling system which utilizes the underground cold storage of the ground heat exchanger (GHE) can improve the indoor comfort and increase the system energy performance. Furthermore, it can effectively alleviate the imbalanced cooling and heating loads of the GHE for a ground-coupled heat pump system.
