基于管网特性变化的热泵空调系统协同优化方法

Collaborative Optimization Method of the GWHP Central Air-conditioning System based on the Change of the Characteristics of Pipe Networks

论述了基于管网特性变化的地下水源热泵中央空调系统协同优化方法,从热泵主机、输配系统和用户末端三方面建模,分析协同关系,得出实际优化设定点。通过一个简化的空调系统,对比计算定频调质和协同优化运行两种条件下的节能效果,说明协同优化方法可以实现系统整体的最大节能效果,并对实际运行有一定的指导意义。

Based on the change of the characteristics of pipe networks,this paper discusses collaborative optimization method of the GWHP central air-conditioning system,models from the heat pump units,distribution system and end users,analyzes collabora-tive relationships and finally concludes the actual optimal set-point. Through a simplified air conditioning system,this paper com-pares and calculates the energy saving effect under the two conditions of fixed frequency conditioning and collaborative optimization control. This paper concludes that the collaborative optimization method can achieve the maximum energy saving effect of the whole system and has certain guiding significance for actual operation.
