Abstract

The present disclosure discloses a networking method device and terminal for an air conditioning unit. The networking method includes: detecting an outside ambient temperature after a target networking indoor unit is started; determining a target operating mode of the target networking indoor unit according to the outside ambient temperature; detecting a system pressure value of a multi-split air conditioning system after an operating duration of the target networking indoor unit in the target operating mode is greater than a preset operating duration; and determining whether the target networking indoor unit belongs to a target networking system according to the system pressure value.

First claim

What is claimed is:

1. A networking method for an air conditioning unit, comprising:
detecting an outside ambient temperature after a target networking indoor unit is started;
determining a target operating mode of the target networking indoor unit according to the outside ambient temperature;
detecting a system pressure value of a multi-split air conditioning system after an operating duration of the target networking indoor unit in the target operating mode is greater than a preset operating duration; and
determining whether the target networking indoor unit belongs to a target networking system according to the system pressure value;
wherein the determining of the target operating mode of the target networking indoor unit according to the outside ambient temperature comprises: adjusting an operating mode of the target networking indoor unit to a first operating mode in a case where the outside ambient temperature is greater than or equal to a preset ambient temperature; and adjusting the operating mode of the target networking indoor unit to a second operating mode in a case where the outside ambient temperature is less than the preset ambient temperature;
wherein when the operating mode of the target networking indoor unit is adjusted to the second operating mode, the determining of whether the target networking indoor unit belongs to the target networking system according to the system pressure value comprises:
detecting whether the system pressure value is greater than or equal to a first preset threshold;
determining that the target networking indoor unit belongs to the target networking system when the system pressure value is greater than or equal to the first preset threshold; and
determining that the target networking indoor unit does not belong to the target networking system when the system pressure value is less than the first preset threshold.

2. The networking method according to claim 1 , wherein when the operating mode of the target networking indoor unit is adjusted to the first operating mode, the determining of whether the target networking indoor unit belongs to the target networking system according to the system pressure value comprises:
detecting whether the system pressure value is less than or equal to a second preset threshold;
determining that the target networking indoor unit belongs to the target networking system when the system pressure value is less than or equal to the second preset threshold; and
determining that the target networking indoor unit does not belong to the target networking system when the system pressure value is greater than the second preset threshold.

3. The networking method according to claim 2 , further comprises:
marking a networking indoor unit belonging to the target networking system with a first identification information after determining that the target networking indoor unit belongs to the target networking system; and
marking a networking indoor unit that does not belong to the target networking system with a second identification information after determining that the target networking indoor unit does not belong to the target networking system.

4. The networking method according to claim 1 , further comprising:
marking a networking indoor unit belonging to the target networking system with a first identification information after determining that the target networking indoor unit belongs to the target networking system; and
marking a networking indoor unit that does not belong to the target networking system with a second identification information after determining that the target networking indoor unit does not belong to the target networking system.

5. The networking method according to claim 4 , wherein after determining whether the target networking indoor unit belongs to or does not belong to the target networking system, the networking method further comprises:
determining an identified networking indoor unit belonging to the target networking system according to the first identification information when the target networking indoor unit is redetermined; and
selecting the networking indoor unit that does not belong to the target networking system as the target networking indoor unit according to the second identification information.

6. The networking method according to claim 1 , further comprising:
determining the target networking system before the target networking indoor unit is started;
obtaining a plurality of networking indoor units in the target networking system;

starting a first networking indoor unit;
selecting the first networking indoor unit as the target networking indoor unit;
turning off the target networking indoor unit after determining whether the target networking indoor unit belongs to the target networking system; and
starting a second networking indoor unit, wherein the second networking indoor unit is a networking indoor unit next to the first networking indoor unit.

7. The networking method according to claim 1 , wherein the first operating mode is an air conditioning cooling mode, and the second operating mode is an air conditioning heating mode.

8. The networking method according to claim 7 , wherein:
the system pressure value is a pressure on an exhaust side of a compressor corresponding to the target networking indoor unit in a case where the operating mode of the target networking indoor unit is adjusted to the first operating mode; and
the system pressure value is a pressure on a suction side of the compressor corresponding to the target networking indoor unit in a case where the operating mode of the target networking indoor unit is adjusted to the second operating mode.

9. A non-transitory computer-readable storage medium having computer program instructions stored thereon, wherein the instructions when executed by a processor implement the networking method for the air conditioning unit according to claim 1 .

10. A networking device for an air conditioning unit, comprising:
a first detecting circuit configured to detect an outside ambient temperature after a target networking indoor unit is started;
a first determining circuit configured to determine a target operating mode of the target networking indoor unit according to the outside ambient temperature;
a second detecting circuit configured to detect a system pressure value of a multi-split air conditioning system after an operating duration of the target networking indoor unit in the target operating mode is greater than a preset operating duration; and
a second determining circuit configured to determine whether the target networking indoor unit belongs to a target networking system according to the system pressure value;
wherein the first determining circuit comprises:
a first adjusting sub-circuit configured to adjust an operating mode of the target networking indoor unit to a first operating mode in a case where the outside ambient temperature is greater than or equal to a preset ambient temperature; and
a second adjusting sub-circuit configured to adjust the operating mode of the target networking indoor unit to a second operating mode in a case where the outside ambient temperature is less than the past ambient temperature; and
the second determining circuit comprises:
a first detecting sub-circuit configured to detect whether the system pressure value is greater than or equal to a first preset threshold when the operating mode of the target networking indoor unit is adjusted to the second operating mode;
a first determining sub-circuit configured to determine that the target networking indoor unit belongs to the target networking system when the system pressure value is greater than or equal to the f
