本文研究了循环风机盘管（FCU）调制控制相对于传统开关控制的节能潜力。建筑物荷载分布首先是在五种不同气候条件下使用EnergyPlus中的酒店建筑模型生成的。由实验数据得出的一组经验曲线代表了可变空气变水FCU的典型性能。通过按照质量和能量平衡方法连接组件模型，构建了由FCU、变速泵和冷却器服务的多个热区组成的系统模型。 仿真结果表明，与传统的开关控制相比，该调节控制可以节省20-30%的风机能量、50-70%的泵能量和2-7%的暖通空调总能量。引用:2019年年度会议，密苏里州堪萨斯城，扩展摘要

This paper investigated the energy saving potential of modulation control of hydronic fan-coil units (FCUs) relative to traditional on-off control. Building load profiles were first generated by using a hotel building model in EnergyPlus under five different climates. The typical performance of variable air variable water FCUs was represented by a group of empirical curves derived from experimental data. A system model consisting of multiple thermal zones served by FCUs, a variable speed pump, and a chiller was constructed by connecting the component models following the mass and energy balance approach. The simulation results showed that the modulation control could save 20-30% in FCU fan energy, 50-70% in pump energy, and 2-7% in total HVAC energy compared with the traditional on-off control.
