中文摘要:
      提出了一种顶板与侧墙结合的复合式空气载能辐射末端新形式,以某办公建筑作为研究对象,通过试验方法研究了这种复合式空气载能辐射末端在冬冷高湿地区的冬季供暖性能.结果表明,该复合式空气载能辐射空调系统在开启后30 min内可达到稳定状态,相比于传统空调供暖速率更快,稳定性更强,且稳定后室内温度变化相对均匀.该系统在冬季供暖性能较好,在人体活动范围内(距地0.2 m至2.2 m处)室内空气温度为16. 5 °C ~ 18.2 °C,相对湿度为33% ~ 36%.当设定温度为16 °C时,可基本满足冬季供暖要求.同时,该系统可有效改善由于物体遮挡而引起的地板温度过低情况,从而有效避免局部不舒适感.这种顶板与侧墙结合的复合式空气载能辐射末端满足冬季供暖需求,同时具备节能舒适的特点.试验结果可为未来空气载能辐射空调系统在冬冷高湿地区的实践应用提供一定的指导作用.
英文摘要:
      A new form of composite air carry energy radiant end combined with roof and sidewall is proposed. An office building is taken as the research object and the heating performance of the composite air carry energy radiant end in cold-winter and high-humidity climate zone is studied by an experimental method. The results show that the composite air carry energy radiant air-conditioning system can reach a stable state within 30 minutes after opening. Compared with traditional air-conditioning system, it has faster heating rate and stronger stability, and the indoor temperature change is relatively uniform after stabilization. The system has good heating performance in winter. In the range of human activity (0.2 m to 2.2 m from the ground), the indoor air temperature is 16.5 °C ~ 18.2 °C, and the relative humidity is 33% ~ 36%. The heating requirement in winter can be met when the temperature is set at 16 °C. In addition, the system can effectively improve the situation that floor temperature is too low due to the occlusion of objects, thereby effectively avoiding local discomfort. The composite air carry energy radiant end combined with roof and sidewall can meet the demand of heating in winter and has the characteristics of energy saving and comfort. The results can provide some guidance for the practical application of air carry energy radiant air-conditioning system in cold-winter and high-humidity climate zone in the future.
