Simulation Method of HVAC Systems Using Self-Adjusting Templates for the Building Energy Simulation Tool 基于建筑能耗模拟工具自调整模板的暖通空调系统模拟方法
本文介绍了在建筑能耗模拟工具(以下简称“工具”)中实现的使用自调整模板的暖通空调系统模拟方法。为了实现可扩展性和可维护性,引入了模块化结构。每个设备都被建模为一个具有公共功能的模块类。这些函数是格式化的。该工具的一个新特性是“模板”结构,它使我们能够大幅减少输入数据。模板是实现的一个部分系统,需要提前准备好,几个部分相互连接。 例如,提供的AHU模板包括多个模块,例如送风机、回风机、加热和冷却盘管、加湿器和控制系统,以便连接介质(例如空气、水和信号)可以用作空调。有几种类型的模板,每个模板外壳(带有外部连接节点的公共接口)都是按类型定义的。如果模板类型相同,则可以很容易地将其替换为另一个模板。模板功能可以减少系统构建过程中模块之间的连接错误。 作为“AHU/FCU”模板外壳类型,实现了各种模板,如“VAV(2线圈,十六进制)”模板、“VAV(1线圈,十六进制)”模板、“CAV(1线圈,十六进制)”模板、“FCU(1线圈或2线圈)”模板等。用户可以用另一个模板替换一个模板,因为这些模板具有相同的界面。因此,在不考虑“一个盘管”和“一个风扇”等每个模块的情况下,我们可以用“FCU”替换“AHU”设备的空调机组,保持外部连接。此外,还提供了“区域”、“热源”、“热源组”、“泵”、“通风”、“电梯”、“热水”、“管道”、“蓄热”和“热电联产”等模板系统。 我们将一组模板定义为“整个建筑”。引文:2017年冬季会议,内华达州拉斯维加斯,会议论文
This paper describes simulation methods of HVAC systems using self-adjusting templates, which are implemented in the Building Energy Simulation Tool (hereafter "the tool"). To achieve extensibility and maintainability, the modular structure has been introduced. Each device is modeled as a module class that has common functions. These functions are formatted. One of the new features of the tool is the "template" structure, which enables us to drastically reduce input data. A template is a partial system implemented, which is to be prepared in advance with several parts connected with each other. For example, an AHU template is provided including several modules such as supply air fans, return air fans, heating and cooling coils, humidifiers, and control systems so that the connecting media, such as air, water, and signals can work as air conditioners. There are several types of the templates, and each template shell (common interface with external connection nodes) is defined by type. A template can easily be replaced with another if they are of the same type. Template functions can reduce errors in the connection between modules during the system building. As "AHU/FCU" template shell types, various templates such as "VAV (2 coils, HEX)" template, "VAV (1 coil, HEX)" template, "CAV (1 coil, HEX)" template, "FCU (1 coil or 2 coils)" template and so on are implemented. It is possible for users to replace a template with another because these templates have the same interface. Therefore, without considering each module such as "a coil" and "a fan", we can replace an air-conditioning unit of "AHU" equipment with "FCU", keeping the external connection. In addition, the template systems such as "Zone", "Heat Source", "Heat Source Group", "Pump", "Ventilation", "Elevator", "Hot Water", "Plumbing", "Thermal Storage", and "Cogeneration" are provided. We define a group of these templates as "The whole building".
