- Abstract:
- A new ground source heat pump system combined with radiant heating/cooling is proposed, and the principles and the advantages of the system are analyzed. A demonstration of the system is applied to a rebuilt building: Xijindu exhibition hall, which is located in Zhenjiang city in China. Numerical studies on the thermal comfort and energy consumption of the system are carried out by using TRNSYS software. The results indicate that the system with the radiant floor method or the radiant ceiling method shows good thermal comfort without mechanical ventilation in winter. However, the system with either of the methods should add mechanical ventilation to ensure good comfort in summer. At the same level of thermal comfort, it can also be found that the annual energy consumption of the radiant ceiling system is less than that of the radiant floor system.
- 提出了一种新型的地源热泵-辐射供冷/暖复合空调系统, 分析了该系统的原理和特点.该系统被应用于镇江西津渡展览馆中, 并利用TRNSYS软件对其热舒适度和能耗进行了模拟分析.结果表明, 地源热泵-辐射供冷暖复合空调系统在冬季采暖运行时, 地板辐射和顶板辐射方式均具有良好的热舒适度, 且无须采用机械通风;在夏季空调运行时, 地板辐射和顶板辐射必须配合合理的机械通风, 才能具有良好的热舒适度;在同样的热舒适度条件下, 顶板辐射供冷/暖的全年能耗比地板辐射低.
