Referring to Fig. 2, in one embodiment, the control method of the multi-split air conditioner includes:
Step S10, the first temperature value and the second temperature that corresponding first temperature sensor of each indoor unit detects are obtained
The second temperature value that degree sensor detects.
In the present embodiment, an outdoor unit of multi-split air conditioner can connect multiple indoor units simultaneously.
Each multi-split air conditioner includes at least two indoor units, i.e. the outdoor unit of multi-split air conditioner has been at least connected with two
A indoor unit.Each indoor unit includes the first temperature sensor and second temperature sensor for detecting room temperature, described
The setting of first temperature sensor is indoors on machine, and the second temperature sensor setting is indoors.
Optionally, the first temperature sensor of each indoor unit is arranged in the shell of machine indoors；The of each indoor unit
Two temperature sensors are arranged in the indoor room region of machine installation indoors, any position in addition to indoor unit position.It needs
It is noted that the distance between the second temperature sensor position and indoor unit present position are greater than pre-determined distance,
So that the more close actual average indoor temperature of second temperature sensor room temperature detected.Wherein, it is described it is default away from
From being chosen as 2 meters, 3 meters, 3.5 meters etc..
For example, when machine runs on heating mode indoors, when temperature reaches set temperature indoors, when control indoor unit stops
Only when the blower of heating output and closing indoor unit, because the electric expansion valve of indoor unit has certain aperture, therefore it can lead
Cause the temperature inside indoor unit casing to rise sharply, at this moment, due to second temperature sensor position and indoor unit present position it
Between distance, be greater than pre-determined distance, it may therefore be assured that second temperature sensor room temperature detected is not by indoor unit
It influences, so that the more close actual average indoor temperature of second temperature sensor room temperature detected.
During multi-split air conditioner operation, each indoor unit for obtaining be currently running in real time corresponding the can be
One temperature sensor room temperature detected controls corresponding interior according to the first temperature sensor room temperature detected
Machine operation, and when indoors, machine runs on heating mode, when temperature reaches set temperature indoors, obtain second temperature sensing
Device room temperature detected；Be also possible to obtain in real time corresponding first temperature sensor of each indoor unit being currently running and
Second temperature sensor room temperature detected, and according to the first temperature sensor or second temperature sensor room detected
Interior temperature controls corresponding indoor unit operation.
Step S20, according to first temperature value and the second temperature value, in first temperature sensor and institute
It states and selects reference temperature sensor in second temperature sensor.
Step S30, the indoor unit is controlled according to the temperature that the reference temperature sensor detects to run.
Optionally, when each indoor unit is run at the beginning, each indoor unit is controlled according to corresponding first temperature sensing
The operation of room temperature detected by device.When machine runs on heating mode indoors, after room temperature reaches set temperature, i.e.,
When the first temperature value that the first temperature sensor detects is more than or equal to set temperature, the first temperature sensor pair is controlled
The indoor unit answered stops heating output, and reduces the aperture of the corresponding system electronic expansion valve of the indoor unit, to guarantee indoor unit
Heat exchanger is unlikely to liquid storage oil storage, influences air conditioner normal operation.That is indoor unit electric expansion valve when carrying out heating output
Aperture is greater than aperture when stopping heating output.For example, indoor unit aperture of electric expansion valve when carrying out heating output is
The aperture of the corresponding electric expansion valve of indoor unit can be reduced to 100P when machine stops heating output indoors by 350P.
It should be noted that the set temperature can be what user needed to set according to own situation, indoor unit is needed
When heating, make the attainable temperature value of institute in room；The set temperature is also possible to air conditioner and is excavated by big data, obtains
In air conditioner location, in the preference temperature of the human body in current time.
Since indoor unit is when stopping heating, electric expansion valve still needs to open, so that indoor unit still can produce
Heat.Therefore, machine runs on heating mode indoors, and stop heating output when, reduce the revolving speed of the blower of the indoor unit,
Continue to avoid room internal temperature how high to heat supply inside room and cause human body uncomfortable to stop indoor unit.In this way, can mention
Usage experience of the high user to air conditioner.
It should be noted that can be the revolving speed of blower being reduced to first when reducing the revolving speed of blower of indoor unit
Revolving speed, wherein the first revolving speed can be 30 revs/min, 50 revs/min etc., continue to avoid indoor unit to heat supply inside room.
For example, the wind speed of blower can be 200 revs/min when machine carries out heating output indoors, machine stops heating output indoors
When, the revolving speed of blower can be reduced to 30 revs/min.Certainly, the case where reducing the revolving speed of the blower of indoor unit may include
The blower for closing indoor unit, i.e., be reduced to 0 rev/min for the revolving speed of blower.
After reducing the revolving speed of blower of indoor unit, because of the reason of electric expansion valve, it may be such that in indoor unit casing
The temperature in portion rises sharply, and leads to temperature detected by the first temperature sensor, the significantly larger than reality in room where the indoor unit
Room temperature.As such, it can be that machine stops heating output and closes blower indoors when machine runs on heating mode indoors
When, in preset duration, the difference of detected temperature between the first temperature sensor and second temperature sensor is calculated, i.e., by the
One temperature sensor the first temperature value detected subtracts the difference that second temperature sensor second temperature value detected obtains.
It should be noted that the preset duration can be 3 minutes, it is also possible to 5 minutes.
When the difference being calculated is more than or equal to the first preset value, using the second temperature sensor as described in
Reference temperature sensor, and corresponding indoor unit is controlled according to the second temperature value that the second temperature sensor detects and is transported
Row.It should be noted that the value range of first preset value can be 2 DEG C -25 DEG C, preferably 10 DEG C, 15 DEG C or 20 DEG C.
Certainly, when the difference being calculated is less than the first preset value, then using first temperature sensor as the reference temperature
Sensor continues to control the first temperature value control operation that the indoor unit is detected according to first temperature sensor.
Specifically, when control indoor unit is run according to second temperature sensor second temperature value detected, second
When room temperature detected by temperature sensor is lower than set temperature, control indoor unit re-starts heating output.
When machine carries out heating output indoors, the aperture of electric expansion valve is adjusted to default aperture.Optionally, described pre-
If aperture is the aperture opened needed for electric expansion valve when indoor unit carries out heating output.Optionally, the default aperture is
250P, 300P or 350P.In this way, machine stops heating output and reduces electronics indoors when machine runs on heating mode indoors
After the aperture of expansion valve, when indoor unit re-starts heating output, then the aperture of electric expansion valve can be restored to reducing
Aperture when preceding.
When machine carries out heating output indoors, the blower for controlling the indoor unit is run with preset rotation speed, controls the room
The blower of interior machine is run with preset rotation speed, so that the quantity of heat given up of indoor unit is quickly spread in the room, it is flat faster to reach the temperature difference
Weighing apparatus.It should be noted that the preset rotation speed is the second revolving speed of difference with the first wind speed, it is chosen as 200 revs/min, 300
Rev/min etc..
Optionally, when machine re-starts heating output indoors, temperature and indoor temperature inside indoor unit casing it
Between, progressively reach temperature difference balance, at this moment, the difference of detected temperature between the first temperature sensor and second temperature sensor
When less than or equal to the second preset value, the indoor unit is controlled again according to the first temperature sensor the first temperature value detected
Operation.It should be noted that second preset value is less than the first preset value, the value range of second preset value is 0 DEG C-
2 DEG C, preferably 0 DEG C, 0.5 DEG C or 1 DEG C.
Optionally, when machine re-starts heating output indoors, temperature and indoor temperature inside indoor unit casing it
Between, progressively reach temperature difference balance, at this moment, the difference of detected temperature between the first temperature sensor and second temperature sensor
When less than the first preset value, using first temperature sensor as the reference temperature sensor, and the indoor unit weight is controlled
New root is run according to the first temperature sensor the first temperature value detected.
It should be noted that it is preferred that being less than or waiting in the difference after controlling the indoor unit and carrying out heating output
When the second preset value, using first temperature sensor as the reference temperature sensor, and the indoor unit root is controlled
The the first temperature value operation detected according to first temperature sensor.
Of course, it is possible to when being that machine re-starts heating output indoors, in the preset duration, in preset duration,
The difference of detected temperature between the first temperature sensor and second temperature sensor is calculated, i.e., is examined the first temperature sensor
The first temperature value surveyed subtracts the difference that second temperature sensor second temperature value detected obtains, and is less than in the difference
Or when being equal to the second preset value, using first temperature sensor as the reference temperature sensor, control the interior
Machine is run according to the first temperature value that first temperature sensor detects.
It should be noted that when machine carries out heating output indoors, the heat diffusion as caused by indoor unit to room
The regular hour is inside needed, therefore, when machine normally heats indoors, institute between the first temperature sensor and second temperature sensor
Detection temperature may have certain difference.So through setting when the difference is greater than or equal to the first preset value, root
Corresponding indoor unit operation is controlled according to the second temperature value that the second temperature sensor detects, and is arranged in the difference
When less than or equal to the second preset value, the indoor unit is detected according to first temperature sensor again first is controlled
That is, using first temperature sensor as reference temperature sensor, and the first preset value and second is arranged in advance in temperature value operation
If having certain difference between value, in this way, can reduce because of indoor unit and the indoor temperature difference, and indoor unit normal operation is made
At influence.
Optionally, when the difference is greater than or equal to the first preset value, using the second temperature sensor as described in
Reference temperature sensor, and corresponding indoor unit is controlled according to the second temperature value that the second temperature sensor detects and is run
Later, when detecting the difference less than the first preset value or the second preset value, using first temperature sensor as
