Construction of 5 layer, the total area of 4365 ㎡, the layer is 4.0 m. It contains: cooling load calculation; air conditioning system division and system solutions to determine the; the wind system design and calculation; indoor air distribution mode and the airflow organization form of sure; duct system design of insulation layer; noise and vibration control, etc. In air conditioning design, 1F use the entire air time to return to the wind the air processing plan. From energy conservation angle consideration, Uses the dew point blast. The air processing unit is located in each level in the air conditioning engine room, New、returns to the wind to send in various air conditioned room after centralism processing, The air current organization form used on delivers the other day, Delivers the gusty area to select square shape drifting. Returns to the gusty area to use the monolayer drifting to return to the gusty area. Other air conditioned rooms because the area is smaller, Uses the air blower plate tube to add the new atmosphere system, Outside the new atmosphere will process to is lower than in the room the air enthalpy value condition, Undertakes
