Abstract
An air conditioner and a communication method for an air conditioner are provided. The air conditioner may include an outdoor unit; an indoor unit; and a central controller connected to the indoor unit through a communication line. The indoor unit may perform periodic communication for transmitting a plurality of periodic packets to at least one of the outdoor unit or the central controller at predetermined periods, and change and transmit the plurality oaf periodic packets so as to decrease a load on the communication line.
Claims20
An air conditioner, comprising:
- an outdoor unit;
- an indoor unit;
- and
- a central controller connected to the indoor unit through a communication line, wherein the indoor unit performs periodic communication for transmitting a plurality of periodic packets to at least one of the outdoor unit or the central controller at predetermined periods, and changes and transmits the plurality of periodic packets so as to decrease a load on the communication line.
An air conditioner comprising:
- an outdoor unit;
- an indoor unit;
- and
- a central controller connected to the indoor unit through a communication line, wherein the indoor unit generates a plurality of periodic packets at predetermined periods and transmits the plurality of generated periodic packets to the outdoor unit or the central controller at the predetermined periods, and wherein the indoor unit changes and transmits the plurality of periodic packets to transmit, in a current period, only data different from data included in a periodic packet transmitted in a previous period.
A communication method of an air conditioner, the communication method comprising:
- performing, by an indoor unit, periodic communication for transmitting a plurality of periodic packets to at least one of an outdoor unit or a central controller connected to the indoor unit through a communication line at predetermined periods;
- and
- changing and transmitting, by the indoor unit, the plurality of periodic packets so as to decrease a load on the communication line.
The communication method according to claim 20, wherein the changing and transmitting the plurality of periodic packets includes:
- storing a first periodic packet of the plurality of periodic packets transmitted the previous period in a memory of the air conditioner;
- updating the first periodic packet stored in the memory based on a difference between the first periodic packet of the plurality of periodic packets to be transmitted in the current period with the first periodic packet stored in the memory;
- and
- transmitting the updated first periodic packet.
