摘　　要：采用地源热泵机组作为冷热源,同时处理送入末端毛细管天棚辐射系统的供水(经板式换热器换成低温热水)与送入室内的新风,实现了辐射吊顶+置换通风系统在住宅建筑中的应用,并对该系统在冬季供暖工况下的室内环境舒适性进行试验研究。结果表明:该系统运行稳定,在冬季可以得到较为舒适的室内热环境,同时也发现了空调系统设计中的不足之处。Ground source heat pump was used as the cool/heat source in this paper to deal with the water circulated in capillary and air - handling unit simultaneously. It realized the application of radiant ceiling and displacement ventilation system in residential buildings. Meantime, we studied the indoor environment comfort of this system in winter. The experimental results indicate that this system can operate steadily, and a good indoor thermal comfort can be achieved. And some deficiencies in air - conditioning system designing were also found.
