Our two buildings, assume building A and B. equipped Mitsubishi centrifugal chiller. The electrical consumption in 2015 as below mentioned. Capacity is approximately same. Now I am taking details to analyze the reason the huge consumption for building A. I already conducted the primary survey on building A. I found the building automation is out of order. Chilled water delta t is not maintained as design. (In building B also, the automation system is out of order). Now I am collecting all details to find out the cause. The problem is the same operation quality follows for two building. Except the condenser pump is placed in building in ground floor.so its power is high compare to building B. I will update more details. Your any comments on this really appreciated.
