In specific implementation, start rotating speed is correspondingly arranged as 9 gears, Vx is designated as；1≤x≤9；Corresponding to each gear
Start rotating speed it is as shown in table 1：
Table 1
| Gear | V1 | V2 | V3 | V4 | V5 | V6 | V7 | V8 | V9 |
| Correspondence rotating speed | 1200 | 1600 | 2000 | 2400 | 2800 | 3200 | 3600 | 4000 | 4500 |
Specific rotating speed operation rule is to carry out as follows：
Step a, when frequency-changeable compressor is run with xth gear Vx start rotating speed, regard xth gear Vx as current shelves
Position；Whether the run time of statistics current gear reaches 180min；If reaching, step b is performed；Otherwise, step c is performed；
Step b, the current gear of frequency-changeable compressor is increased to (x+1)th gear Vx+1, with (x+1)th gear Vx+1 start
Rotating speed is continued to run with；And count whether the run time run with (x+1)th gear Vx+1 start rotating speed reaches 30min, if
Reach, then perform step d；Otherwise, step c is performed；
Step c, the gear according to corresponding to the Homes Using TV table of comparisons 2 of current gear obtains next start rotating speed；
Table 2
| Homes Using TV | Start next time gear |
| >86% | Vx+4 |
| 83%-86% | Vx+2 |
| 78%-83% | Vx+1 |
| 72%-78% | Vx |

Step d, the current gear of frequency-changeable compressor is increased to the 9th gear V9, with opening corresponding to the 9th gear V9
Machine rotating speed runs up to shutdown；
Whether step e, statistics frequency-changeable compressor are reached with the run time of the start rotating speed operation corresponding to the 9th gear V9
To 15min；If reaching, the gear corresponding to order start next time rotating speed is the (x+1)th gear Vx+1 of current gear；Otherwise,
Perform step f；
Whether step f, statistics frequency-changeable compressor are reached with the run time of the start rotating speed operation corresponding to the 9th gear V9
To 30min；If reaching, the gear corresponding to order start next time rotating speed is+2 gear Vx+2 of xth of current gear；Otherwise,
Gear corresponding to order start next time rotating speed is the 9th gear V9.
It is a kind of using control rule mechanical frequency-changeable compressor, be between 72%-78% be target Homes Using TV, rise or
Person reduces rotating speed to shorten or extend the run time of frequency conversion press so that Homes Using TV is close to target Homes Using TV.And to run
Time is that main shaft is divided into several periods：
Period one：0---180min；With current rotating speed Vx run, shut down within the time period, next time start rotating speed according to
Drawn according to Homes Using TV control rotating speed operation rule table 3；
Period two：180----210min；Current rotating speed is shut down, next time starts within the time period with Vx+1 grades of operations
Rotating speed is drawn according to Homes Using TV control rotating speed operation rule table 3；
Period three：210----225min；Current rotating speed is now shut down with V9 grades of operations, then start next time rotating speed is direct
With Vx+1 grades of operations；
Period four：225----240min；Current rotating speed is now shut down with V9 grades of operations, then start next time rotating speed is direct
With Vx+2 grades of operations；
Period five：More than 240min；Current rotating speed is with V9 grade operations, until shutting down, then start next time rotating speed it is direct with
V9 grades of operations.
Specific rules are as follows：
When Vx, if run time reaches 180min, now current rotating speed increases by one grade to Vx+1 grades, such as runs
Do not shut down yet to during 210min, then current rotating speed jumps directly to V9 grades of highest, i.e. 4500RPM.
When frequency-changeable compressor run time is in 210min, start next time rotating speed is calculated by Homes Using TV：
Homes Using TV>When 86%, start next time rotating speed is Vx+4；
During Homes Using TV 83%-86%, start next time rotating speed is Vx+2；
During Homes Using TV 78%-83%, start next time rotating speed is Vx+1；
During Homes Using TV 72%-78%, start next time rotating speed is Vx；
During Homes Using TV 65%-72%, start next time rotating speed is Vx-1；
Homes Using TV<When 65%, start next time rotating speed is Vx-2；
When frequency-changeable compressor is with V9 rotating speeds, and run time is more than 210min, now then using the run time of V9 rotating speeds as
Foundation, it is determined that start next time rotating speed：
In 210min between when running<T<During 225min, next time, start rotating speed was started shooting with Vx+1 rotating speeds；
In 225min between when running<T<During 240min, next time, start rotating speed was started shooting with Vx+2 rotating speeds；
Between when running>During 240min, next time, start rotating speed was started shooting with V9 rotating speeds；
As shown in Fig. 2 Vx was the available machine time and downtime according to a upper cycle in Fig. 2, Homes Using TV is thus calculated,
The table 3 that rotating speed operation rule is summed up is compareed again, draws corresponding start rotating speed as Vx under this Homes Using TV.
Table 3：
In table 3, TVX represents the run time on corresponding speed；The implication of table 3 is as follows：
When running to 180 minutes with Vx, frequency-changeable compressor is not reaching to halt condition, then current rotating speed Vx increases by one grade
Vx+1 grades；
Halt condition is still not up to when frequency-changeable compressor runs to 210 minutes, then current rotating speed increases to V9 grades
(4500RPM), shutdown is run up to V9 grades；
When frequency-changeable compressor run time is when within 210 minutes, Homes Using TV is calculated, then draw by operation rule table 3
Corresponding start rotating speed；
When frequency-changeable compressor with V9 rotating speed run times between 210---225min when, then next time start rotating speed be Vx+1
Shelves, now do not determine rotating speed further in accordance with Homes Using TV；
When frequency-changeable compressor with V9 rotating speed run times between 225---240min when, then next time start rotating speed be Vx+2
Shelves, now do not determine rotating speed further in accordance with Homes Using TV；
When frequency-changeable compressor is more than 240min with V9 rotating speeds run time, then start next time rotating speed is V9 grades, now not
Rotating speed is determined further in accordance with Homes Using TV.
