Computer Simulation of Hydronic Heating/Cooling System with Embedded Pipes 嵌入式管道循环供暖/制冷系统的计算机模拟
在许多情况下,建筑物的热调节基于建筑围护结构(墙壁、窗户)在隔热和太阳能传输方面的优化,并结合加热/冷却和/或通风系统。与其使用全空调,还可以在多层建筑的楼层之间的混凝土板上安装嵌入式管道,以循环热水或冷水。这不仅可以在混凝土板表面提供直接加热或冷却,还可以由于混凝土板的蓄热能力而产生额外的效果。本文给出了这种系统的动态计算机模拟结果。结果表明,与不制冷相比,通过将年最高工作温度降低10 K,热舒适性显著改善。每年可获得超过60 kWh/m2的冷却。单位:干燥: 研讨会,ASHRAE交易,第106卷,pt。1.
In many cases the thermal conditioning of buildings is based on an optimization of the building envelope (walls, windows) with regard to insulation and solar transmission, combined with a heating/cooling and/or ventilation system. Instead of using full air conditioning, it may be possible to condition a space with embedded pipes circulating warm or cool water in the concrete slabs between the floors in a multistory building. This will not only provide direct heating or cooling over the surface of the slab but also an additional effect due to the thermal storage capacity of a concrete slab. This paper presents the results of a dynamic computer simulation of such a system. The results showed a significant improvement of thermal comfort by reducing the annual maximum operative temperature by 10 K compared to no cooling. Annually more than 60 kWh/m2cooling could be obtained.Units: SI
