夜间辐射制冷在地源热泵中的应用

摘要

针对地源热泵技术用于冷负荷占优型建筑物时地下热积累导致的性能下降问题,提出了应用夜间辐射散热器作为辅助散热器的新型地源热泵复合系统.设计了夜间辐射散热器,构建了夜间辐射散热器及新型复合系统的解析解模型,并编写了相应的系统运行模拟程序.以香港某小型住宅为例,设计了新型地源热泵复合系统,并对其运行性能及能耗进行了模拟计算.依据计算结果分析了夜间辐射制冷在地源热泵技术中应用的可行性.%Aiming at the performance degradation of ground-source heat pump technology used in cooling load dominant buildings,puts forward a new ground-source heat pump hybrid system with auxiliary night radiators.Designs a night radiator,constructs an analytical solution model of night radiator and new hybrid system,and compiles the corresponding system operating simulation program.Taking a small residential house in Hong Kong as an example,designs a new type of ground-source heat pump hybrid system,and simulates its operating performance and energy consumption.Based on the calculation results,analyses the feasibility of the application of night radiant cooling technology to the ground-source heat pump.
