The peak power control system comprises a central control unit for controlling a multi-air conditioner system including a plurality of multi-air conditioners each having an outdoor unit and a plurality of indoor units in an integrated manner, and operating the multi-air conditioner system at a reference operation rate, and a demand control unit for sending/receiving data to/from the central control unit to control power consumption of the multi-air conditioner system such that the power consumption is less than total reference power consumption allocated to a building.

Abstract: Disclosed herein are a building management system (BMS) and an operating method thereof. A BMS controller of a LonWorks network integrally controls a multi-air conditioner system which uses a different communication scheme, without modification of the structure thereof. The building management system comprises a BMS controller (50) for centrally controlling subsystems (60 and 70) installed in the building and connected to a LonWorks network (N2), an air conditioner system (70) including a plurality of outdoor units (71) and a plurality of indoor units (72) connected to the outdoor units, and a Lon gateway (80) for converting data of an air conditioner system network (N1) into data of the LonWorks network (N2), and vice versa, to enable the BMS controller (50) to centrally control the air conditioner system (70). The building management system can incorporate a multi-air conditioner system which utilizes a different communication technology, without modification.

A low-price built-in server is installed in each household appliance to assign the corresponding appliance a unique IP address simply over the Internet to be controlled according to an external user control command. A home server is connected to each of the household appliances such that the corresponding appliance receives a control command, sent in transit by a user from a mobile terminal.

Abstract: A central control system includes a plurality of air conditioners and a central control unit connected to the air conditioners over a network. The air conditioners are installed in rooms of a building to provide air conditioning in the rooms. The central control unit receives a control command for monitoring and controlling each of the air conditioners, and adjusts an operating schedule of each of the air conditioners to limit total peak power consumption of the air conditioners in operation below a reference power value. The central control unit controls the operation of each of the air conditioners based on the adjusted operating schedule. When the total peak power consumption exceeds the reference power value, the central control unit prevents the entire air conditioning system from shutting down, which improves stability of the air conditioning system and decreases electricity costs for air conditioning.

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.
