Power Shift with Coordination Both Ice Storage and Central Air Conditioner Mainframe

The electricity consumption of commercial buildings is discussed in terms of rank of load ratio which is most of the air-conditioning power consumption is used. And the air-conditioning of commercial building uses ice storage and central air conditioner to adjust the indoor temperature and humidity to complete a comfortable working environment. Both Ice storage equipment and central air conditioner use the electric power to match the peak and off-peak loading period by coordination strategy to make ice and melt ice which can save the consumption power. Firstly, to investigate the load characteristic curves of the air conditioner mainframe (ACM) and ice storage. Secondly is to collect electricity consumption data of commercial key-customers and analyze the proportion and relationship of power consumption of related conditioning equipment. Coordination both of ice storage and ACM that can suppress the peak loading and base on the peak and off-peak period in load curve of the commercial key-customer to derive the index parameter of power suppress of peak power or power shifting.
