Application of enthalpy difference control method to air conditioning system of a nuclear power plant

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.
