摘要:
建筑节能是可持续发展战略的重要内容,而空调系统是公共建筑节能的主要组成,文章围绕建筑围护结构的蓄热特性,以地板辐射供冷系统为研究对象,通过选取济南市安泰动态节能示范楼内三个典型空调房间,利用TRNSYS仿真模拟软件建立地源热泵地板辐射供冷模型,结合建筑控制平台实测数据,对建筑围护结构的室内热环境进行研究,探索地板辐射供冷系统建筑围护结构蓄热特性。结果表明:建筑西外墙对室内热环境的稳定和舒适性影响最大;外墙对室外温度波具有明显的衰减特性和峰值延迟特性,良好的蓄热特性有利于系统节能运行,维持室内温度;墙体的蓄热性使得室温波动较小,白天蓄热有效地阻止冷负荷的陡然增大,维持了正常工作时间人员的空调需求;14∶00地板蓄冷量最低,室温超过空调设计温度,应采取增大地板盘管供水流量或降低供水温度的措施,降低室内温度,确保系统节能高效运行。
Abstract:
The building energy efficiency is the top priority of sustainable development strategy, and the air conditioning system is the major component for the public building energy saving. This paper focuses on the thermal properties of building envelope, and the floor radiant cooling system is chosen as the research object. Through selecting three typical air conditioning rooms from an Antaeus energysaving demonstration building in Jinan, this paper establishes the floor radiant direct supply cooling system model by using TRNSYS simulation software. This research studies the indoor thermal environment and mainly focuses on the characteristics of thermal storage for the building envelopes, combined with the buildings control platform data. The results show that west wall of the building has a great effect on the indoor thermal environments stability and comfortable. The wall has obvious performance of attenuation and peak delay for the outdoor temperature wave. Good thermal storage characteristic of exterior wall is useful for energy saving operation of system and maintaining the indoor temperature. The thermal storage characteristic of building envelopes makes the indoor air temperature fluctuate with smaller values, and the wall thermal storage characteristic in the day can prevent the cooling load suddenly increasing effectively to maintain air conditioning requirements for the personnel in the normal working hours. At 14:00 the cold storage capacity for the floor is lowest and the indoor temperature is larger than the design temperature for the air conditioning. The measures should be taken to increase the supply water flow rate or reduce the temperature of the supply water to reduce the indoor temperature and ensure the efficient operation of the system.
