摘要
辐射供冷与置换通风复合系统不仅能提供较高的热舒适性,并且具有很大的节能潜力,本文建立了复合系统的能耗分析模型,并采用EnergyPlus能耗分析软件对该复合系统进行能耗模拟,模拟得到的室内温度和辐射地板所承担冷量与实验结果的误差小于±7%,在此基础上,改变置换通风的送风温度,得到辐射地板提供冷量随置换通风送风温度提高而增加的变化规律,置换通风送风每增加1℃,辐射地板提供的冷量增加1.9%左右。
Radiant cooling with displacement ventilation air conditioning system not only provides high thermal comfort, but also is energy efficient. Energy consumption model of this hybrid system was built and analyzed by software EnergyPlus. By comparison of simulation results and experimental data, the simulated indoor air temperature and cooling capacity provided by radiant floor was ±7% deviated from the experimental data. Based on the simulation model, it is deduced that the cooling capacity provided by radiant floor increased with the supply air temperature of displacement ventilation. When the supply air temperature increased by IcE, the corresponding cooling capacity of radiant floor increased by 1.9%.
