太阳能地板辐射供暖制冷系统模型仿真

近年来,我国北方地区新建住宅的采暖系统多数采用地板辐射供暖技术,而制冷系统仍采用传统的空调制冷技术,有必要对地板辐射制冷技术的应用进行研究,为此,针对一套实验用太阳房,搭建了太阳能地板辐射供暖制冷系统.通过计算确定了集热器面积、蓄热水箱体积、吸收式制冷机组的制冷量.利用TRNSYS仿真平台建立了系统仿真模型,并对控制策略进行了验证.仿真结果表明,该系统能有效地利用太阳能保持冬季室温18℃左右、夏季26℃左右的舒适温度.

Modeling and Simulation of Solar Floor Radiant Heating/Cooling System

In recent years,most new residential heating system in northern China use radiant floor heating technology,but refrigeration systems still use traditional air conditioning and refrigeration technologies.It is necessary to undertake a study on application of floor radiation refrigeration technology.To do this,for an experimental solar house,solar floor radiant heating and cooling system is built.A calculation to determine the solar collector area,storage water tank volume,absorption chiller cooling capacity is performed.A system is established with TRNSYS simulation platform for simulation models,and the control strategy is verified.Results show that the system effectively uses solar energy to maintain room temperature around 18 ℃ in winter and around 26 ℃ for summer.
