Embodiment
The actual temp section that compressor frequency runs managed temperature control is: compressor frequency needs the temperature range of frequency limit TFrequency limit[52 DEG C, 55 DEG C)；Compressor frequency needs the temperature range T of frequency reducingFrequency reducing[55 DEG C, 61 DEG C).The temperature of compressor shutdown Spend section TIt shuts down≥61℃。
Multi-connected machine ABC tri- interior machines put into heating operation, 18 DEG C of A machine indoor environment temperature, B machine indoor environment temperature 17 DEG C, 18 DEG C of C machine indoor environment temperature, temperature setting all be 20 DEG C.Machine is 26 machines in A, and B machine is 35 machines, and C machine is 50 machines.Outer machine Ability PAlwaysIt is 80.
Compressor calculates target frequency=70Hz using F and brings into operation as target, and calculating at this time is illustrated by taking A internal pipe temperature as an example The operating condition of target frequency and actual motion frequency；
1) when A machine inner tube is less than 52 DEG C, compressor actual motion frequency calculates target frequency=70HZ using F and transports as target Row, when actual motion frequency, which reaches F, calculates target frequency=70HZ, complete machine compressor will keep 70Hz operation.
2) when A machine inner tube is in [52 DEG C, 55 DEG C) between when, compressor frequency is limited in current frequency, such as practical fortune A machine inner tube=52 DEG C when line frequency is 67HZ, then compressor frequency will be limited in 67HZ no longer raising frequency to 70HZ.
3) A machine inner tube rise to [55 DEG C, 61 DEG C) enter high temperature-proof frequency reducing section reduce 2Hz operation.
Such as compressor F target frequency reduces: FTarget A× f%=(20HZ × 20%)=4HZ, while updating FTarget A= 20HZ-4HZ=16HZ；FTarget=F target 1+ ... F target i × (1-f%)+...+F target n=70HZ-4HZ=66HZ.
Actual motion reduces 2HZ: Δ F=C × Σ P/PAlways=2 × (25+35+50)/80=2HZ.
If before meeting frequency reducing, actual frequency 70HZ then then drops after frequency reducing 2HZ than calculating target frequency 66HZ high It is run as low as target frequency 66HZ is calculated.If actual motion frequency is 64HZ before frequency reducing, 2HZ to 62HZ operation is reduced. (being run by small frequency reducing)
4) after frequency reducing A machine inner tube be still in [55 DEG C, 61 DEG C) frequency reducing section, then run t=5 minutes complete machines of Δ current Frequency reducing (while reducing calculating target frequency: F again on the frequency base of actual motionTarget A× f%=16HZ × 20%=3HZ, it is real Border running frequency reduces Δ F=C × Σ P/PAlways=2HZ).After Δ t=5 minutes, judge whether temperature A machine inner tube is in [55 DEG C, 61 DEG C), if it is it is again introduced into frequency reducing.
FTarget=FTarget 1+…FTarget i× (1-f%)+...+FTarget n=66HZ-3HZ=63HZ.
Actual motion frequency reduces 2HZ: Δ F=C × Σ P/PAlways=2 × (25+35+50)/80=2HZ.For example, current real Border running frequency is 62HZ, then reduces 2HZ to 60HZ operation.If currently practical running frequency is 66HZ, after reducing 2HZ 64HZ is than calculating target frequency 63HZ high, then actual motion frequency is reduced to 63HZ operation.(being run by small frequency reducing)
5) because the inner tube of B machine, C machine is not up to frequency reducing temperature and frequency needs do not decline (A machine calculate target frequency be reduced to most Low is 0, FTarget B+FTarget C>=50HZ), compressor operating frequency is minimum to be reduced to 50HZ operation, and compressor operating frequency will not The frequency reducing again due to the protection of A machine high temperature-proof, A machine inner tube will gradually rise to 61 DEG C of high temperature-proof protection shutdown at this time, and A machine inner tube is gradually It is reduced to 52 DEG C or less and exits high temperature-proof protection investment heating operation (to avoid frequency frequent fluctuation, A machine at least stops 20min).A Machine restarting after, at this time target frequency restore 70Hz, compressor raising frequency arrive 60Hz when A machine 52 DEG C of high temperature-proof frequency limits of inner tube, press Contracting machine is limited in currently practical running frequency 60HZ operation.If D machine increases heating at this time, frequency will not be limited by A machine high temperature-proof The limitation of frequency, target frequency are updated to 86Hz, and compressor executes raising frequency.55 DEG C of anti-height of A machine inner tube when during raising frequency to 76Hz Temperature drop frequency 2Hz, at this time by the high temperature-proof frequency reducing for judging an A machine for Δ t=5 minutes, A machine is stopped by frequency reducing, frequency limit, frequency reducing ... later Machine ... exits.
It is merely a preferred embodiment of the present invention, is not intended to restrict the invention, for the technology of this field described in upper For personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
