Research on Energy Saving of Radiant Floor with Ribbed Water Supply Pipe Based on TRNSYS
摘要: 本文基于肋片效率法提出了一种简化加肋供水管辐射地板模型，将计算结果与实验数据比较，得出该模型上表面、下表面温度及出口水温均方根误差分别为0.03℃、0.36℃和0.08℃，验证了该模型的准确性。利用该简化模型，通过TRNSYS搭建了空气源热泵空调系统对杭州某住宅的供热仿真平台。并在该平台分析了供水管加肋辐射地板在间歇运行下的节能性，结果表明该地板对比普通地板在供暖周期内空调系统总能耗降低18.64%，空气源热泵COP提高了0.065，地板响应时间提高了57.1%。
Abstract:
In this paper, a simplified finned water supply pipe radiation floor model is proposed based on the finned efficiency method. Comparing the calculated results with the experimental data, the root- mean-square errors of the upper surface temperature, lower surface temperature and outlet water temperature of the model are 0.03˚C, 0.36˚C and 0.08˚C respectively, which verifies the accuracy of the model. Based on this simplified model, TRNSYS was used to build a simulation platform of air source heat pump air-conditioning system for a residential building in Hangzhou. The energy-saving performance of the radiant floor in intermittent operation was analyzed on the platform. The re-sults show that the total energy consumption of the air-conditioning system is reduced by 18.64%, COP of the air source heat pump is increased by 0.065, and the response time of the floor is in-creased by 57.1%.
