The project adopts closed inter-row water-cooled terminal precision air conditioners. In the initial operation stage, the load rate is low, and the terminal air conditioner manufacturer’s operating parameters are improperly set. The excessive high cold aisle humidity in the computer room and much alarms in summer seriously affect the safety of IT equipment, and cause certain energy waste. By measuring the temperature and humidity of the closed cold aisle and the operating power of the air conditioner under different operating parameters of air conditioners and the constant humidity machine, while taking into account safety and energy saving, selects the operating parameters of the inter-row air conditioner. By applying the test results to the entire computer building, obtains the optimal hot and humid environment of the computer room and the obvious energy saving effect.
