In high temperature and high humidity seasons,high temperature alarms or equipment condensations occur frequently in the southeast coastal nuclear power plants,which affects the safety of pump motor operation and reduces the safety and reliability of cold sources.A method of adding a mixed air refrigeration unit in the inlet air room is proposed,which does not change the current ventilation mode.The unit adopts two loops of fresh air,and mixes the fresh air after refrigerated and dehumidified with the fresh air outside.The inlet air parameters are determined by calculation.This method does not require to cool all fresh air and need no reheating segments,and it is to reduce the relative humidity by mixing air and increasing temperature,which is available to completely solve the problem of excessive temperature and humidity in the essential service water pump house under all working conditions,and take account of the economics.
