The AGV battery replacement station of automation container terminal has a complex process,and the charging equipment emits huge heat when it works.The charging area working temperature shall be controlled between 20～35 ℃ to meet the cooling,dehumidification and anti-salt fog environment requirements.Taking the phase IV project of Shanghai Yangshan deepwater port as an example,we research the designs scheme of ventilation and air conditioning,and determin using split air conditioning.The system has the characteristics of flexible load regulation and the use of safe and reliable.It ensures that the air conditioning and ventilation system of the battery replacement station can operate stably for a long time,and can reduce the energy consumption of the air conditioning and ventilation system.
