Abstract

A communication system of a multi-type air-conditioner and its method are disclosed. The communication system includes a main outdoor unit for wirelessly transmitting/receiving data to/from a plurality of slave outdoor units; an outdoor relay unit for communicating with the main outdoor unit through a fixed line serial communication method; an indoor relay unit for communicating with the outdoor relay unit through a local area communication network or a fixed line; and a plurality of indoor units for wirelessly communicating with the indoor relay unit.

Claims

1. A communication system of a multi-type air-conditioner comprising:

a main outdoor unit for wirelessly transmitting/receiving data to/from a plurality of slave outdoor units;

an outdoor relay unit for communicating with the main outdoor unit through a fixed line serial communication method;

an indoor relay unit for communicating with the outdoor relay unit through a local area communication network or a fixed line; and

a plurality of indoor units for wirelessly communicating with the indoor relay unit.

2. The system of claim 1, wherein the outdoor relay unit transmits/receives network data to/from the indoor relay unit.

3. The system of claim 2, wherein when the outdoor relay unit receives data from the main outdoor unit according to the fixed line serial communication method, it converts the received data into network data and transmits the converted network data to the indoor relay unit.

4. The system of claim 2, wherein when the outdoor relay unit receives network data from the indoor relay unit, it converts the received network data into wireless communication data and transmits the converted wireless communication data to the main outdoor unit.

5. The system of claim 2, wherein when the indoor relay unit receives network data from the outdoor relay unit, it converts the received network data into wireless communication data and transmits the converted wireless communication data to the plurality of indoor units.

6. The system of claim 2, wherein when the indoor relay unit receives wireless communication data from the plurality of indoor units, it converts the received wireless communication data into network data and transmits the converted network data to the outdoor relay unit.

7. The system of claim 1, wherein the plurality of slave outdoor units, the main outdoor unit, the indoor relay unit and the plurality of indoor units include a wireless communication unit for wirelessly transmitting/receiving data, respectively.

8. The system of claim 7, wherein the wireless communication unit is a Bluetooth communication module.

9. A communication system of a multi-type air-conditioner comprising:

a plurality of slave outdoor units; and

a main outdoor unit for wirelessly transmitting/receiving data to/from the plurality of slave outdoor units.

10. The system of claim 9, wherein the plurality of slave outdoor units and the main outdoor unit include a wireless communication unit for wirelessly transmitting/receiving data, respectively.

11. A communication system of a multi-type air-conditioner comprising:

a plurality of indoor units; and

an indoor relay unit for wirelessly transmitting control information of a main outdoor unit for controlling the plurality of indoor units to the plurality of indoor units, wirelessly receiving data of the plurality of indoor units, and transmitting the received data to the main outdoor unit.

12. The system of claim 11, wherein the plurality of indoor units include a wireless communication unit for wirelessly receiving the control information and wirelessly transmitting the data, respectively.

13. A communication method of a multi-type air-conditioner comprising:

wirelessly transmitting/receiving data by a plurality of slave outdoor units and a main outdoor unit;

transmitting data of the main outdoor unit to an outdoor relay unit through fixed line serial communication;

receiving, by the outdoor relay unit, the transmitted data and transmitting the received data to an indoor relay unit through a local area communication network or a fixed line; and

wirelessly transmitting by the indoor relay unit the data which has been received through the local area communication network or fixed line to a plurality of indoor units.

14. The method of claim 13, wherein the step of transmitting data to the indoor relay unit comprises:

converting the received data into network data by the indoor relay unit.

15. The method of claim 13, wherein the step of transmitting data to the plurality of indoor units comprises:

converting the transmitted data into wireless communication data by the indoor relay unit.

16. A communication method of a multi-type air-conditioner comprising:

wirelessly transmitting data by a plurality of indoor units;

wirelessly receiving the data by an indoor relay unit;

transmitting, by the indoor relay unit, the received data to an outdoor relay unit through a local area communication network or a fixed line; and

transmitting by the outdoor relay unit the received data to a main outdoor unit through a fixed line.

17. The method of claim 16, wherein the plurality of indoor units and the indoor relay unit include a wireless communication module for wirelessly transmitting/receiving data, respectively.

18. A communication method of a multi-type air-conditioner comprising:

wirelessly receiving data of a plurality of slave outdoor units by a main outdoor unit; and

wirelessly receiving data of the main outdoor unit by the plurality of slave outdoor units.

19. The method of claim 18, wherein the main outdoor unit and the plurality of slave outdoor units include a wireless communication module for wirelessly transmitting/receiving data, respectively.
