建筑环境设计模拟分析软件DeST第9讲冷热源与水系统模拟分析(下)

冷热源系统是整个集中空调系统的核心，它决定了系统能否保障用户的冷热需求，是投资的主要部分，也是能源消耗的主要部分。同时冷热源产生的冷热量主要依靠水系统输配到各末端用户中去。因此冷热源与水系统的联合优化设计是整个空调系统设计过程中至关重要的环节。综述了目前冷热源与水系统联合模拟的现状，详细阐述了DeST模拟软件中冷源和水系统模拟所采用的的模型与模拟方法。通过介绍一个设计实例，指出了冷热源与水系统全工况模拟的应用范围和实际意义。

Building environment design simulation software DeST(9) :simulation and analysis of cooling/heating plants(part 2)

A central chilling and heating system is one of the most important parts of the HVAC system: the cooling/heating plant has to be designed to meet the cooling and heating demands of the whole building, to be low in initial costs and efficient in operation; the water/air distribution systems have to properly distribute cooling and heating media to the terminal units. Reviews the different methods for the cooling devices and water distribution system simulation. Describes the simulation models and methods suitable for the building energy consumption simulation, in the DeST program for the cooling/heating plant and water distribution system. Also explains how to do the cooling/heating plant and water distribution system full year simulation in the DeST program with an example.
