Central control system of air conditioners and method for operating the same
A central control system of air conditioners includes a multi-type air conditioning system, a power meter and a central controller. The air conditioning system includes a plurality of indoor units for air conditioning installed in rooms of a building and an outdoor unit for circulation of refrigerant, where the indoor units share the outdoor unit. The power meter is connected to the outdoor unit to measure power consumption of the air conditioning system when the system operates. The central control unit calculates respective power consumptions of the indoor units based on both the power consumption measured by the power meter and operation information of the air conditioning system, and displays the calculated power consumptions of the indoor units. It is thus possible to determine respective power consumption patterns and electricity charges of the indoor units more accurately, thereby improving management efficiency of the entire air conditioning system.
