  • Publication number: 20110218681
    Abstract: An air conditioning system and a method of controlling the same are provided. The air conditioning system may include at least one outdoor device, at least one indoor device connected to the at least outdoor device, voltage and current sensors installed in the at least one outdoor device, and a control device installed at or in the at least outdoor device, that collects operating information of the at least outdoor device and the at least one indoor device and calculates power consumption of the air conditioning system based on operating information, and voltage and current information. In such an air conditioning system, power consumption of the air conditioning system may be calculated via estimation using current and voltage values obtained by the current and voltage sensors and operating information of the at least one indoor device, whereby costs associated with installation of an additional power distribution device may be eliminated.
