暖通空调系统的动态建模对于建筑节能控制分析是非常重要的。为了给研究人员提供一个分析不同控制策略的仿真平台，本文介绍了一个基于动态暖通空调部件模型的定制Simulink块库的仿真平台。作为一项初步工作，当前的模拟平台由基本的模块化暖通空调组件组成，包括管道、阻尼器/阀门、风扇/泵、合流、分流、加热盘管、冷却盘管和区域。这些模块被开发成Simulink定制模块。该仿真平台能够根据系统特性和风机曲线，通过可定制的基本/高级控制策略，计算新风、排风和回风的流量。通过对不受控、定温和阻尼器位置控制以及基于进度的重置控制情况的比较，提出了采用单区定容系统的实例研究。仿真结果表明，基于调度表的温度和风门位置重置对供暖季和冷季的节能效果均有显著影响。该仿真平台特别适用于分析不同暖通空调控制策略的动态性能。
Dynamic modeling of HVAC system is extremely important for control analysis toward building energy saving. In order to provide researchers a simulation platform to analyze different control strategies, this paper introduces a simulation platform with customized Simulink block library based on dynamic HVAC component model. As an initiating effort, the current simulation platform is composed of basic modular HVAC components, including conduit, damper/valve, fan/pump, flow merge, flow split, heating coil, cooling coil, and zone. These modules are developed into Simulink customized blocks. The simulation platform is capable to calculate the flow rates of fresh air, exhaust air, and return air based on system characteristic and fan curve with customizable basic/advanced control strategies. A case study is proposed using single-zone, constant volume system by comparing the uncontrolled, fixed temperature and damper position controlled, and schedule based reset controlled cases. The simulation result proves that schedule based temperature and damper position reset has a significant impact on energy saving for both heating and cooling seasons. This simulation platform can be especially useful for analyzing the dynamic performance of different HVAC control strategies.
