Central air conditioning system and control method for super high-rise building

The invention discloses a central air conditioning system and a control method for a super high-rise building. The Central air conditioning system and the control method for the super high-rise building comprises a low-area air conditioning system, a high-area air conditioning system, an ultra high-area conditioning system and a highest-area air conditioning system, wherein the low-area air conditioning system comprises a general air-condition cold water main engine, a low-area chilled water circulating pump and low-area users, the high-area air conditioning system comprises a high-area heat exchanger, a high-area chilled water circulating pump and high-area users, the ultra high-area conditioning system comprises a ultra high-area heat exchanger, a ultra high-area chilled water circulating pump and ultra high-area users, the highest-area conditioning system comprises a highest-area heat exchanger, a highest-area chilled water circulating pump and highest-area users. By the adoption of a closed system, chilled water of a common loading capacity cold water main engine is guaranteed to be provided to each terminal with only once heat transfer to reduce twice or three times heat transfer and the fact that a large number of air-condition main engine energy consumption under the premise of meeting the requirement of terminal humiture is saved is achieved, the central air conditioning system and the control method for the super high-rise building meets the requirement of energy-saving and cost-reducing environment. The central air conditioning system and the control method for the super high-rise building is reliable in project and good in energy-saving effect.
