摘要
水基吊顶辐射板供冷系统可以提供一个无强烈冷空气对流和噪声的舒适热环境.建立水基吊顶辐射板末端供冷系统模型,结合辐射末端供冷与谷电制冰,通过循环水系统将冰块中储存的冷量输送至辐射板,测量室内垂直方向上的温度分布,分析谷电制冰的吊顶辐射板室内供冷功能.在大连市某厂区办公室进行实例应用,对该方式的应用效果和热经济性进行研究.研究表明,水基吊顶辐射板末端供冷系统可以有效降低室内温度,满足人员热舒适度要求,使用谷电供能制得的冰块作为冷源,辐射板的运行成本可以减少60%.
Abstract
Water-based ceiling radiant panel cooling system can provide a comfortable thermal environment without strong cold air convection and noise.A model of water-based ceiling radiant panel end cooling system is established.Combined with radiant end cooling and off-peak electricity ice making,the cold stored in ice cubes is transported to the radiant panel through a circulating water system,and the indoor vertical temperature distribution is measured to analyze the indoor cooling function of ceiling radiant panel for off-peak electricity ice making.The method is applied in a factory office in Dalian,and the application effect and thermal economy of this method are studied.The research shows that the end cooling system of water-based ceiling radiant panel can effectively reduce indoor temperature and meet the requirements of thermal comfort of personnel.Using ice cubes produced by off-peak power supply as cold source,the operating cost of radiant panel can be reduced by 60%.
