本文介绍了一个模拟环境开发，以评估空心通风板系统的能量性能。开发的仿真环境结合了瞬态有限差分求解通风板系统与RC网络模型的多层建筑。所开发的模拟环境考虑了通风板系统热桥对多层建筑节能性能的影响。开发的模拟环境的预测进行验证，从一个详细的全建筑能源模拟工具。此外，几个参数分析进行，以确定在各种设计和操作条件下的通风板系统的性能。特别地，参数分析包括供应空气入口温度、空气质量流率、空芯深度和空芯直径的影响。特别是，它被发现，由于增加通过板边缘的热传递增加由于热桥效应，通风板需要5%以上的加热和7%以上的冷却能量的最终用途。
This paper presents a simulation environment developed to assess the energy performance of hollow core ventilated slab systems. The developed simulation environment combines a transient finite difference solution of a ventilated slab system with an RC network model for a multi-floor building. The developed simulation environment takes into account ventilated slab system thermal bridge effects on the energy performance of multi-floor buildings. The predictions of the developed simulation environment are verified against those obtained from a detailed whole-building energy simulation tool. In addition, several parametric analyses are performed to determine the performance of ventilated slab systems under various design and operating conditions. In particular, the parametric analyses include the effect of supply air inlet temperature, air mass flow rate, hollow core depth, and hollow core diameter. In particular, it is found that due to increased heat transfer through slab edge increases due to thermal bridge effects, ventilated slab requires 5% more heating and 7% more cooling energy end-uses.
