INVESTIGATION ON AIR-CONDITIONING ENERGY CONSUMPTION OF A TYPICAL COMMERCIAL BUILDING COMPLEX

The air-conditioning energy consumption of a typical commercial building complex was investigated in four aspects: the component of energy consumption, cooling load parameters, coefficient of performance and coefficient of water conveyance. Suggestions on improving the air-conditioning systems were proposed as follows; (1) combining the south and the north primary system into a unit one, (2) adding frequency control for water pump, (3) modifying the running scheme of fresh air handling units, (4) intensifying the management and maintenance of the system.
