Embodiment Construction
[0018] figure 1 A block diagram showing the structure of the multi-channel air conditioner central control system according to the present invention.
[0019] like figure 1 As shown, the multi-channel air conditioner central control system according to the present invention includes a plurality of multi-channel air conditioners (100 and 200) and a plurality of watt-hour meters 300, wherein each multi-channel air conditioner includes a plurality of indoor units 100 and indoor The outdoor units 200 to which the units 100 are commonly connected, each watt-hour meter is used to measure the power consumption of a specific one of the outdoor units 200 within a predetermined time, thereby calculating the power consumption of the corresponding indoor unit 100 .
[0020] Each watt-hour meter 300 is adapted to measure the power consumption of the specific outdoor unit 200 which is the same as the total power consumption of the plurality of indoor units 100 connected to the specific out...

Disclosed herein are a multi-air conditioner central control system and a power control method thereof. The central control system comprises a plurality of watt-hour meters for measuring power consumption of a plurality of multi-air conditioners each having an outdoor unit and a plurality of indoor units, to compute power consumption of the respective indoor units, and a central control unit for dividing power consumption of the respective indoor units into operating power consumption and standby power consumption according to operation or nonoperation of the respective indoor units and a particular one of the outdoor units connected with the indoor units, and accumulating integral power consumption of the respective indoor units by adding the operating power consumption and standby power consumption thereof. The power control method is adapted to determine whether the respective multi-air conditioners are in operation or not to allocate a larger portion of available power to multi-air conditioners in operation through power redistribution. Thus, power consumption states of the respective multi-air conditioners can be more accurately identified in real time, and power management of the multi-air conditioners can be efficiently performed.
Description
technical field [0001] The present invention relates to a multi-way air conditioner central control system and its power control method, wherein the power consumption received by an outdoor unit connected to a plurality of indoor units is divided into standby power consumption and operating power consumption of the indoor unit, so that the indoor unit Those that are not active do not accumulate active power consumption. Background technique [0002] Recently, air conditioners have been widely used, and they are installed in each room of a home or each office of a building. [0003] These air conditioners are mainly divided into two types. One is a single type air conditioner suitable for air conditioning in a small room, and the other is a multi-type air conditioner system installed in a large building and requiring coordinated management. The single type air conditioner includes an indoor unit installed in a room and an outdoor unit installed outside the room and connecte...
