摘　　要：地板辐射系统的优化控制是提高室内热舒适性、节约能耗的必要手段。文章以地板辐射系统与置换通风复合系统为研究对象,基于不同的室内热湿环境状况,采用能耗模拟软件分析和比较了不同间歇运行方式对室内热环境的影响及能耗,针对4种典型工况系统实施不同的控制措施,阐明了适用于各工况的最优调控措施及复合供冷系统优先级调控策略。结果表明:地板辐射供冷系统间歇运行方式中设计运行参数更具优势;相比调控地板辐射系统,调控送风系统更适用于室内得热突增情况,室内得热量较高时,优先调整地板供冷系统运行参数,增加供水流量至0.8 m^(3)/h,能够更好地保证室内舒适性,而其较低时地板供水流量可减小至0.3 m^(3)/h,保证了室内温度、湿度维持在规定范围内。The optimal control of floor radiant system is a necessary way to improve indoor thermal comfort and save energy consumption.Taking the floor radiant cooling system and displacement ventilation composite system as the research object,based on different indoor thermal and wet environment conditions,using energy consumption simulation software,this paper analyzes and compares the impact of different intermittent operation modes on indoor thermal environment and energy consumption,implements different control measures for four typical working conditions,and expounds the optimal control measures applicable to each working condition and the priority control strategy of composite cooling system.The results show that the design of operation parameters is more advantageous in the intermittent operation mode of floor radiant cooling system.Compared with the floor radiant system,controlling air supply system is more applicable for the sudden increase of indoor heat gain.When the indoor heat gain is high,it is of priority to adjust the operative parameters of the floor radiant system,so the rate of water supply should be increased to 0.8 m^(3)/h to ensure better indoor comfort.When the indoor heat gain is low,the rate can be reduced to 0.3 m^(3)/h to ensure that the indoor temperature and humidity are maintained within the specified range.
