变风量系统空调房间建模与特性参数估算

Modeling and Estimating of the Characteristic Parameters for the Air Conditioning Room of the VAV System

讨论了变风量空调系统的基本原理 ,根据定风量方式下空调房间的数学模型和特性参数的估算公式 ,结合变风量系统的特点 ,推导出变风量方式下空调房间的数学模型以及两种送风方式下特性参数的关系 ,对研究变风量系统的协调控制问题具有重要的理论意义和明显的实用价值。

The fundamental principle of the VAV air conditioning system was presented. According to the mathematical model of the room in the way of the CAV (Constant Air Volume) and estimate formulas of characteristic parameters, the mathematical model of the room in the way of the VAV was deduced based on characteristics of the VAV system. Then, the relationship of characteristic parameters of the room about two types of systems was discussed. Study for control of the VAV system has reference value.
