摘要
节能环保以及室内环境的舒适性是现代暖通空调技术发展的一个基本趋势.毛细管辐射空调由于其舒适性高、导热能力快、不占用建筑使用空间、节能效果明显等优点越来越受人们的关注.在此背景下,提出通过建立置换通风+毛细管地板辐射的热传导模型,数值模拟该复合空调供给的热湿环境参数,并与实验测得的温度、湿度、速度、PMV、PPD值进行对比,得出不同供水温度与换热量的关系,分析该复合空调的供冷能力.该研究为促进供暖/供冷一体化技术在长春地区的发展应用提供一定的参考价值.
Energy saving and environmental protection and the comfort of indoor environment are a basic trend in the development of modern HVAC technology.Capillary radiation air conditioners are attracting more and more attention because of their advantages such as high comfort,fast heat conduction,no use of building space,and obvious energy saving effects.Under this background,the heat and humidity environment parameters provided by the composite air conditioner was simulated by establishing a heat conduction model of displacement ventilation and capillary floor radiation,and the results were compared with the experimentally measured temperature,humidity,speed,PMV and PPD values.The relationship between different water supply temperatures and heat exchange capacity was analyzed,and the cooling capacity of the composite air conditioner was analyzed.It will provide certain reference value for the development and application of integrated heating/cooling technology in Changchun.
