Air conditioning system

Abstract

In an air conditioning system that uses short-range wireless communication through pairing, this system suppresses errors in the combination of the indoor air conditioning unit with other equipment. [Solution] The first device, a remote controller 10, has a first communication unit 11. The indoor air conditioning unit 2, which provides air conditioning to the room, has a second communication unit 21 that communicates with the first communication unit 11 via short-range wireless communication. The first communication unit 11 and the second communication unit 21 pair during the first communication and communicate normally during the second communication. The first communication unit 11 or the second communication unit 21 reduces the transmission output during the first communication to less than the transmission output during the second communication. If the first communication unit or the second communication unit, which has reduced the transmission output during the first communication, fails to pair within a predetermined period, it increases the transmission output during the first communication.

Claims

1. A first device (10) having a first communication unit (11), An air conditioning indoor unit (2) that provides air conditioning to the room has a second communication unit (21) that performs short-range wireless communication with the first communication unit, Equipped with, The first communication unit and the second communication unit perform pairing during the first communication and perform normal communication during the second communication. The first communication unit or the second communication unit reduces the transmission output during the first communication to less than the transmission output during the second communication. The first communication unit or the second communication unit, which has set the transmission output during the first communication to be smaller than the transmission output during the second communication, will change the transmission output during the first communication to increase the transmission output if pairing cannot be achieved within a predetermined period or if the number of pairing retries exceeds a predetermined number. Air conditioning system (1).

2. A first device (10) having a first communication unit (11), The air conditioning indoor unit (2) has a second communication unit (21) that performs short-range wireless communication with the first communication unit, Equipped with, The first communication unit and the second communication unit perform pairing during the first communication and perform normal communication during the second communication. The first communication unit and the second communication unit reduce the transmission output during the first communication to less than the transmission output during the second communication. The first communication unit and the second communication unit, during the first communication, if pairing cannot be achieved within a predetermined period or if the number of pairing retries exceeds a predetermined number, change the transmission output during the first communication to increase the transmission output. Air conditioning system (1).

3. The transmission output during the first communication, which is smaller than the transmission output during the second communication, is less than 0 dBm. The air conditioning system (1) according to claim 1 or 2.

4. The first device is a remote controller (10) for remotely operating the indoor unit of the air conditioner. An air conditioning system (1) according to any one of claims 1 to 3.

5. During the first communication, the first communication unit increases the transmission output in response to a predetermined operation on the first device. An air conditioning system (1) according to any one of claims 1 to 4.

6. The first device or the indoor unit of the air conditioner has a reset function for initializing the pairing of the first communication unit and the second communication unit. An air conditioning system (1) according to any one of claims 1 to 5.
