and S306, determining whether a communication line in the multi-split air-conditioning system has a fault according to the difference value between the indoor temperature and the inlet pipe temperature and/or the difference value between the inlet pipe temperature and the outlet pipe temperature.
Through the steps S302 to S304, whether the communication lines in the multi-split air-conditioning system have faults or not can be determined according to the difference value between the indoor temperature and the inlet pipe temperature and/or the difference value between the inlet pipe temperature and the outlet pipe temperature by starting the preset number of indoor units, so that the problem that the pipelines and the communication lines are easily connected in a wrong mode in the installation process of the multi-split air-conditioning system in the related technology to cause the communication lines not in the same set of system is solved, and the effect of accurately detecting whether the communication lines in the multi-split air-conditioning system have faults or not is achieved.
It should be noted that the operation modes referred to in this application at least include: a cooling mode, a heating mode and an air supply mode. The present application will be described in detail with reference to the above-described specific modes of operation.
In an optional implementation manner of this embodiment, in a case that the operation modes include a cooling mode and a blowing mode, the triggering step S302 in this embodiment of the present embodiment of the preset number of indoor units in the multi-split air conditioning system to be in the operation mode includes one of the following:
step S302-11, triggering all indoor units in the multi-split air-conditioning system to be in a refrigeration mode;
step S302-12, triggering half of the indoor units in the multi-split air-conditioning system to be in a refrigeration mode, and the other half of the indoor units in the multi-split air-conditioning system to be in an air supply mode;
and S302-13, triggering one indoor unit in the multi-split air-conditioning system to be in a cooling mode, and enabling the rest indoor units to be in an air supply mode.
It should be noted that, all the indoor units in the trigger system are started to operate in a refrigeration mode; the purpose is to judge whether the indoor unit can work normally when being fully opened, namely whether the fault of wrong connection of a communication line exists; half of the indoor units run in a refrigeration mode, and the other indoor units run in an air supply mode, so as to judge whether a fault of wrong connection of communication lines exists under a heavy load condition; and one indoor unit is started to operate in a refrigeration mode, and the other indoor units operate in an air supply mode, so that the purpose of judging whether a problem exists under a small load condition, namely whether a fault that a communication line is connected in a wrong way exists is achieved.
Of course, when the operation mode includes the cooling mode and the air supply mode, the three situations are only preferred embodiments of the present application, and may also be other preset number of situations, for example, one third of the indoor units are in the cooling mode, the remaining indoor units are in the air supply mode, and the like, and corresponding adjustment and setting may be performed according to actual situations.
Based on the manner of determining whether a fault exists in the communication line of the multi-split air conditioning system according to the difference between the indoor temperature and the inlet pipe temperature and/or the difference between the inlet pipe temperature and the outlet pipe temperature in step S306 in the present embodiment, when the operation mode includes the cooling mode and the air supply mode, the following manners may be implemented:
step S306-11, determining that a communication line in the multi-split air-conditioning system has a fault under the condition that the difference value between the indoor temperature and the inlet pipe temperature is greater than a first preset temperature value and the difference value between the inlet pipe temperature and the outlet pipe temperature is greater than a second preset temperature value;
and S306-12, determining that the communication line in the multi-split air-conditioning system has no fault under the condition that the difference between the indoor temperature and the inlet pipe temperature is less than or equal to a first preset temperature value or the difference between the inlet pipe temperature and the outlet pipe temperature is less than or equal to a second preset temperature value.
That is, under the condition that the cooling mode and the air supply mode exist simultaneously, the difference between the indoor temperature and the inlet pipe temperature needs to be compared with a first preset temperature value, and the difference between the inlet pipe temperature and the outlet pipe temperature needs to be compared with a second preset temperature value. The specific first preset temperature value and the specific second preset temperature value can be taken as corresponding values according to actual conditions, such as 3 ℃, 5 ℃ and the like.
In another optional implementation manner of this embodiment, the operation mode referred to in this application may also be a heating mode, in which case the manner that triggers the preset number of indoor units in the multi-split air conditioning system to be in the operation mode referred to in step S302 of this embodiment includes:
and S302-21, triggering all indoor units in the multi-split air-conditioning system to be in a heating mode.
In another optional implementation manner of this embodiment, the operation mode referred to in this application may be an air supply mode, and in this case, the manner for triggering the preset number of indoor units in the multi-split air conditioning system to be in the operation mode referred to in step S302 of this embodiment includes:
and S302-31, triggering all indoor units in the multi-split air-conditioning system to be in an air supply mode.
Based on the above steps S302-21 and S302-31, the manner of determining whether a communication line in the multi-split air conditioning system has a fault according to the difference between the indoor temperature and the inlet pipe temperature and/or the difference between the inlet pipe temperature and the outlet pipe temperature in step S306 of this embodiment may be implemented as follows:
s306-21, determining that a communication line in the multi-split air-conditioning system has a fault when the difference value between the indoor temperature and the inlet pipe temperature is greater than a third preset temperature value;
and S306-22, determining that the communication line in the multi-split air-conditioning system has no fault when the difference value between the indoor temperature and the inlet pipe temperature is less than or equal to a third preset temperature value.
That is, in the single heating mode or the air blowing mode, only the difference between the inlet pipe temperature and the outlet pipe temperature needs to be compared with the third preset temperature value. And for the specific third preset temperature value, corresponding values can be taken according to actual conditions, such as 3 ℃, 5 ℃ and the like.
It should be noted that, although the steps S302-11 to S302-13 and the steps S302-21 may be executed sequentially or individually in this application, the detection accuracy of the communication line is the highest when the communication line is sequentially executed in different modes, that is, after the indoor unit is set in the cooling mode and the air supply mode, it is further determined that the indoor unit is set in the heating mode and the last air supply mode.
