答﹕
做法1 - 優先考慮用Equally Sized System, 用六台1000kW shift 住用,即係peak load期間壞咗都叫有一台後備,即係N+1. (鳴謝Ir.理查德修正)
可考慮再加一台後備Air Cool Chiller for emergency
原因 - 好處係easy design, control, operation, less spare parts for easy maintenance;
做法2 - 如果用Unequally Sized System Swing Chiller Design, 可考慮用一台3500kW既chiller, 再搭一台1500kW, 由於大多數時間唔係行Peak load, 齋開一台3500kW都夠頂,再唔夠的話就開埋台1500kW; 如果到放工或假日,就淨係台1500kW細機運作;
原因 - Maximize energy efficiency;
當然最終係要睇埋load profile, initial cost and maintenance cost嚟考慮,以上只係簡化既答案
