不同末端形式下双冷源辐射空调系统模拟研究

Simulation Study of Dual Cold Source Radiant Air Conditioning System with Different Terminals

本文采用EnergyPlus能耗模拟软件,以上海市某别墅为建筑对象,对顶板/墙面辐射+置换通风两种不同双冷源空调系统进行设计工况下的热舒适和能耗模拟分析,同时与VRV空调系统的模拟结果进行对比。结果表明:与VRV系统相比,墙面辐射双冷源空调系统具有更好的热舒适性、更低的能耗。达到相同的热舒适度标准,所用时间更少。全年供冷主机能耗可节约50%,供热主机能耗可节约23%。

Using EnergyPlus energy simulation software,a villa in Shanghai was taken as an example.The thermal comfort and energy consumption of the roof/wall capillary radiation+displacement ventilation with dual cold source air-conditioning systems are analyzed under the design conditions,while the VRV air conditioning system is served as a simulation reference.The simulation results show that compared with the VRV system,the wall-radiation dual-cold source air-conditioning system has better thermal comfort and lower energy consumption;toward the same thermal comfort standard can save a lot of time;The energy consumption of the cooling plant can be saved by 50%,and the energy consumption of the heating plant can be saved by 23%.
