The quantity of the indoor unit 14 switched every time controls multiple 14 running mode switchings of indoor unit.
Specifically, air-conditioning system 10 is multi-online air-conditioning system, and air-conditioning system 10 includes outdoor unit 12, the number of outdoor unit 12
Amount can be one or more, and the quantity of outdoor unit 12 is 2 in the illustrated embodiment.Air-conditioning system 10 can pass through 2
Outdoor unit 12 is that multiple indoor units 14 realize refrigeration and heating needs, be can be applied in different environment, for example, large-scale field
Shop, computer room and office space etc..
It is appreciated that in air-conditioning system 10 when receiving multiple 14 running mode switchings of indoor unit, multiple indoor units 14
Switch simultaneously so that high pressure and low pressure conducting moment often generate larger since high-low pressure pressure difference is larger and the pressure time is longer
Noise and continue longer time.
In some embodiments, the operational mode of air-conditioning system 10 include refrigeration mode, heating mode, oil return mode and
Defrost pattern.
Wherein, air-conditioning system 10 includes oil return apparatus 15, and compressor is discharged with cold media gas for separating in oil return apparatus 15
11 lubricating oil, and isolated lubricating oil is supplied to compressor 11, avoid compressor 11 from damaging because of oil starvation.However, oil return
Device 15 can not accomplish the lubricating oil being kept completely separate in cold media gas, still remain a small amount of lubricating oil with refrigerant and enter condensation
In device, evaporator and respective line, for multi-online air-conditioning system, since system pipeline is long, drop is big, elbow is more, system is deposited
The place of oil is more, in multi-online air-conditioning system long-play, is easy to cause 11 oil starvation of compressor.
Multi-online air-conditioning system needs are switched to oil return mode when the oil mass of 11 lubricating oil of compressor is less, or every pre-
If duration is switched to oil return mode, to recycle the lubricating oil remained in condenser, evaporator and respective line.Therefore, air-conditioning
When system 10 is switched to oil return mode, it usually needs while switching the operational mode of multiple indoor units 14.
In addition, when air-conditioning system 10 runs heating mode at low ambient temperatures, since refrigerant absorbs heat in outdoor unit 12, so that
The temperature of outdoor unit 12 further decreases, and is easy to cause the solidifying frost of outdoor unit 12, influences the operation of air-conditioning system 10.Therefore, air-conditioning
The needs of system 10 are switched to defrost pattern when the temperature of outdoor unit 12 is lower, or are switched to defrost pattern every preset time,
To dissolve the solidifying frost of outdoor unit 12, guarantee that air-conditioning system 10 operates normally.Similarly, air-conditioning system 10 is switched to defrost pattern

Face can effectively reduce the noise grade that more sound source superpositions generate and increase, and on the other hand, switching can be acted on due to pressure every time, cut
It changes after operational mode and carries out the noise grade of single sound source switching again and will decay, advantageously ensure that maximum when running mode switching
The control of noise grade.
Specifically, in step s 2, the quantity of the indoor unit 14 of running mode switching is needed to can be n, switching times
It can be m times, the quantity of the indoor unit 14 of i-th switching can be niIt is a；Wherein, n >=2,2≤m≤n, 1≤i≤m, n=
∑ni, and n, m, i are positive integer.
In some embodiments, step S2 can first the indoor unit 14 of running mode switching as needed quantity determine
Switching times, then the quantity of the indoor unit 14 of running mode switching as needed and switching times determine the interior switched every time
The quantity of machine 14.
In this way, control device 13 can be preset with switching time corresponding with the quantitative range for the indoor unit 14 for needing to switch
Number is needing the quantity of the indoor unit 14 switched that can determine switching times in corresponding range.For example, it is desired to switching
When the quantity of indoor unit 14 is in 2-4 ranges, corresponding switching times are 2 times；The quantity for the indoor unit 14 for needing to switch
When in 5-8 ranges, corresponding switching times are 3 times.Then the quantity of the indoor unit 14 switched every time is determined.
In some embodiments, step S2 can first determine the quantity of the indoor unit 14 switched every time, then according to need
The quantity of the indoor unit 14 of running mode switching is wanted to determine switching times.
Specifically, control device 13 is preset with the maximum quantity of the indoor unit 14 switched every time.For example, switching for the first time
Maximum quantity is 1, and the maximum quantity of second of switching is 3, and the maximum quantity of third time switching is 5, the room for needing to switch
Interior machine 14 is assigned in switching every time, when the quantity of the indoor unit 14 once switched before being assigned to reaches maximum quantity, needs to cut
The indoor unit 14 changed is assigned to be switched next time.In this way, being cut for the first time when needing the quantity of the indoor unit 14 switched to be 7
The quantity of the indoor unit 14 changed can be 1, and the quantity of the indoor unit 14 of second of switching can be 3, third time switching
The quantity of indoor unit 14 can be 3.
It should be noted that the quantity of the indoor unit 14 switched every time can be not limited to embodiment discussed above, and
It can flexible configuration according to the actual situation.The quantity of the indoor unit 14 switched every time can be identical or not identical.
In some embodiments, step S2 includes: the noise grade according to running mode switching and needs switchover operation

The quantity of the indoor unit 14 of operational mode determines the quantity of the indoor unit 14 switched every time, noise grade and the same room once switched
The quantity of interior machine 14 is related.
It is appreciated that the noise grade size of the switching noise generated when 10 running mode switching of air-conditioning system and air-conditioning system
10 high-pressure sides of uniting are related to the pressure difference of low-pressure side, in addition, noise grade is also related with the factors such as the density of refrigerant, and coolant quantity
Number directly affect pressure change needed in time and handoff procedure switching noise duration.In multiple indoor units 14
Simultaneously when running mode switching, there can be multiple 14 simultaneous switching noise complex superpositions of indoor unit and noise grade is increased.
In this way, when gradation is to multiple 14 running mode switchings of indoor unit, it is contemplated that noise slept to user or worked
It influences, the quantity of the indoor unit 14 switched every time can be determined in conjunction with noise grade, advantageously ensure that air-conditioning system 10 is right

Grade is related to the quantity of sound source.Specifically, when the noise grade of single sound source determines, air-conditioning system 10 generates switching noise
The quantity of noise grade and sound source has exponent relation.
In some embodiments, when switching times are twice or more, the indoor unit 14 that once switches before determining
Quantity is less than the quantity of the indoor unit 14 once switched afterwards, in other words, ni< n (i-1).
For air-conditioning system 10, control device 13 can be used for when switching times are twice or more, primary before determining
The quantity of the indoor unit 14 of switching is less than the quantity of the indoor unit 14 once switched afterwards.
In this way, the quantity of the indoor unit 14 switched every time gradually increases, since pressure acts on, rear primary high-pressure side and low
It presses the pressure difference between side to reduce, so that the noise grade of single sound source gradually decreases under repeatedly acting on, switched to control
The duration of the maximum noise grade of more sound source superpositions and switching noise in journey.
In some embodiments, when switching times are three times or more, the adjacent time interval switched twice is identical.
It is appreciated that there is certain time interval between adjacent switching twice, so that air-conditioning system when preceding primary switching
10 can reach stable even results.In this way, the adjacent time interval switched twice is identical, the switching of air-conditioning system 10 has one
Fixed rule.In one example, the adjacent time interval switched twice is 0.5-2 seconds, preferably, it is adjacent switch twice when
Between between be divided into 1 second, when 10 running mode switching of air-conditioning system, there is certain non-uniform time, meanwhile, can be to avoid interval time
It is too long so that noise duration is too long.
Certainly, in other embodiments, the adjacent time interval switched twice can not be identical.
