其中自訂參數模式依據各空調主機之耗電決定運轉之優先順序，耗電高之空調主機為優先停機，耗電低之空調主機為優先運轉。其中節能效益計算，係進入耗電智能自動運轉控制模式前，收集各空調主 機運轉容量與每冷凍噸耗電，計算改善前空調耗電，進入耗電智能自動運轉控制模式後，收集運轉台數、各空調主機運轉容量與每冷凍噸耗電等智能分析結果，計算改善後空調耗電。再透過改善前空調耗電與改善後空調耗電，進而算出空調機組運轉容量最佳化之節能效益。 The custom parameter mode determines the priority of operation according to the power consumption of each air-conditioning host. The air-conditioning host with high power consumption is given priority to stop, and the air-conditioning host with low power consumption is given priority. Among them, the calculation of energy saving benefits is to collect the main air conditioner before entering the intelligent automatic operation control mode of power consumption.
