Tztmin。
S33, Tzr is judged>Whether=(Tztmin+Ty) be true, if set up, performs step S34；Otherwise, return is held
Row step S32；Wherein, number when Tzr is the outer machine cumulative activation operated, Ty are default time threshold, and Ty values can be pre-
Setting, for example, can be 4 it is small when, 5 it is small when or 6 it is small when etc..
S34, the outer machine of the operating of stopping, the outer machine of number minimum when starting cumulative activation, i.e. Tztmin are corresponding outer
Machine realizes quality balance operating.
Fig. 5 is the another kind for the outer machine balanced running control method of VRF Air Conditioning System that the method for the present invention embodiment provides
The flow chart of preferred embodiment.It is as shown in figure 5, different from machine balanced running control method outside the VRF Air Conditioning System that Fig. 4 is provided
Part is, in step s 32, if more than one outer machine operating, searches cumulative activation minimum in the outer machine to shut down
When number Tztmin and the outer machine that is operating in maximum cumulative activation when number Tztmax, perform step S33 afterwards；Or it looks into
Several accumulative works larger in number and the outer machine operated when looking for smaller several cumulative activations in the outer machine to shut down
Number when making, afterwards directly stop cumulative activation when several larger outer machines of number, startup cumulative activation when smaller several outer machines of number,
Smaller several outer machines of number work when several larger outer machine-cuts of number during cumulative activation being changed to cumulative activation.It is described to stop
The outer machine only operated and the outer machine number operated may be the same or different, as the case may be depending on.
In step S33, Tztmax is judged>Whether=(Tztmin+Ty) be true, wherein, Ty is preset time threshold, such as
Fruit is set up, then performs step S34；Otherwise, step S32 is performed.
In step S34, stop the outer machine of number maximum during cumulative activation, the outer machine of number minimum when starting cumulative activation.
Remaining step is identical with the outer machine balanced running control method of the VRF Air Conditioning System that Fig. 4 is provided, and does not do herein tired
It states.
Machine outside VRF Air Conditioning System is controlled using control method described above, it is ensured that each outer machine is balanced
Operating so that the service life of each outer machine is consistent.
Machine balanced running control method outside VRF Air Conditioning System is illustrated below, the data in table 2 are tired
Work hours are counted, when representing that number is 4 small during cumulative activation such as 4 (ON) in Tz1, the first outer machine is operating.
At the Ts1 moment, the first outer machine is operating, added up operating 4 it is small when；Second outer machine stops, before add up to transport
Turn 4 it is small when；3rd outer machine stops, before add up to operate 3 it is small when.In the outer machine to shut down at this time during minimum accumulative operating
Between Tztmin be 3, corresponding 3rd outer machine.Ts2 moment Tz1>=(Tztmin+Ty) i.e. 9>During=(3+6), stop the first outer machine,
Start the 3rd outer machine, into the Ts3 moment, at this time Tztmin become the second outer machine 4 it is small when.
When system runs to Ts4 moment, Tz3>=(Tztmin+Ty) i.e. 10>During=(4+6), stop the 3rd outer machine, start
Second outer machine, into the Ts5 moment, at this time Tztmin become the first outer machine 9 it is small when.At the Ts6 moment, stop the second outer machine, open
Dynamic first outer machine, into the Ts7 moment.The rest may be inferred.This ensure that when each outer machine accumulated running time difference is small no more than 6,
Realize quality balance operating.
