Application of enthalpy difference control method to air conditioning system of a nuclear power plant
摘要：
介绍了焓差控制法在核电厂空调系统中的应用:在满足系统功能的前提下,通过优化送风温度范围来扩大空调系统运行工况范围以达到节能效果。介绍了系统最小新风量和冬、夏季工况点的设定,空气比焓的计算及系统控制逻辑的实现。运行结果表明,空调系统运行稳定且节能效果良好,可为核电厂空调系统应用焓差控制法提供参考。
Abstract：
This paper presents the application of enthalpy difference control method to the air conditioning system of a nuclear power plant:under the premise of satisfying the system function,the energy saving effect can be further improved by optimizing the air supply temperature range to expand the operation condition range of the air conditioning system.This paper presents the setting of the minimum outdoor air volume,the working points in winter and summer,the calculation of air specific enthalpy and the realization of the system control logic.The operation results show that the air conditioning system has stable operation and good energy saving effect,which can provide a reference for the application of enthalpy difference control method to air conditioning systems of nuclear power plants.
