Central control system of air conditioners and method for operating the same
First Claim
1. A central control system of air conditioners, comprising:
- a multi-unit type air conditioning system including a plurality of indoor units for air conditioning installed in rooms of a building and an outdoor unit for circulation of refrigerant, said outdoor unit being shared by the plurality of indoor units;
a power meter, connected to the outdoor unit, for measuring power consumption of the multi-unit type air conditioning system when the multi-unit type air condition system operates; and
a central controller for calculating respective power consumption of the indoor units based on both the power consumption measured by the power meter and operation information of the multi-unit type air condition system, and for displaying the calculated respective power consumptions of the indoor units,wherein said central controller includes;
an air conditioner communicator for transmitting and receiving signals to and from the multi-unit type air conditioning system and the power meter via a communication line;
a database for storing equipment information of the indoor and outdoor units of the multi-unit type air conditioning system;
an air conditioner controller configured to control operations of the multi-unit type air conditioning system and to allow display of respective power consumptions of the indoor units calculated based on the current operation information of the multi-unit type air conditioning system and the equipment information stored in the database;
an electricity charge calculator configured to calculate respective electricity charges of the indoor units based on the respective power consumptions of the indoor unit units calculated by the air conditioner controller; and
a display configured to display the respective electricity charges of the indoor units calculated by the electricity charge calculator or displaying the respective electricity charges of the indoor units calculated by the air conditioner controller.

Abstract
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.
