空调系统全局优化控制参数节能性研究

Research of Control Parameters Optimization for HVAC Systems

空调系统通常都没有运行在设计工况下,未能充分发挥系统整体的能力或者达到系统最高的效率。为使空调系统高效地运行,文中提出智能全局优化控制的策略,可以降低能耗,同时优化控制空调系统。文中选取空调送风温度、冷冻水供水温度以及冷却水供水温度作为整个空调系统的独立控制参数建立系统的能耗模型。在模拟过程中对比分析传统控制策略和智能全局优化控制策略,发现利用智能全局优化控制策略总能得出最经济的控制参数,使空调系统更经济。这样的控制模式也更加有利于空调系统运行过程的节能。

While always running in non-design condition, HVAC systems of buildings are not able to behave the system efficiency and ability. In this paper, in order to make HVAC systems operate efficiently in non-design conditions, global optimization control strategy with intelligent algorithms was put forward, which can reduce energy consumption and optimize control. Temperatures of supplied air, chilled water and cooling water were chosen as independent control parameters of energy consumption model of HVAC systems. Through the simulation and the comparative analysis of the simulation results of traditional control strategy and intelligent global optimization control strategy, the conclusion that optimal control parameters can always be fotmd using intelligent global optimization control strategy, and therefore the HVAC systems will be able to be more efficient than the traditional. This proposed strategy will contribute much to energy conservation during HVAC system running period.
