This design is mainly aimed at building in the control system of the air conditioning unit system, and its peripherals. This design is focused on the United States a BAC munication based on ai agreement with good flexibility and openness and development BACtalk building automation system, the design and to Qingdao polar ocean polar world museum central air conditioning, for example focuses on the air conditioning unit for research.
