Description
Technical field
The present invention relates to field of household appliances, more particularly to a kind of control method of air-conditioner.
Background technology
In correlation technique, the control method of compressor of air conditioner running frequency is mostly based on indoor return air temperature, outdoor return temperature
Degree and certain algorithm calculate compressor operating frequency, while considering that compressor longtime running reliability and the noise of compressor are asked
Topic, compressor operating frequency can be all limited in certain scope.As this control method is not accounted in just start system
During cold operation, use environment and user are bigger than when stable operation to the refrigeration demand of air-conditioner, so each air-conditioning producer
Meeting Jing often receives consumer with regard to the slow complaint of refrigerating speed.
The content of the invention

Air-conditioner when freezing to interior, by compressor by the refrigerant vapor compression of low pressure into high pressure steam
Cold-producing medium, then cold-producing medium be changed into the liquid refrigerant of high pressure by outdoor heat exchanger, the liquid refrigerant of high pressure flows through throttling
Element gets in heat exchanger, indoor air is absorbed heat, compressor is then back into, is completed to indoor refrigeration.
The height of air-conditioner refrigeration depends primarily on the running frequency of compressor, and compressor is in higher running frequency
Lower work can cause refrigeration to be obviously improved, but the service life of compressor can be affected by certain, and higher
The noise that the compressor worked under running frequency is produced also accordingly can increase.
The control method of air-conditioner according to embodiments of the present invention is described in detail with reference to Fig. 1 and Fig. 2.
The control method of air-conditioner according to embodiments of the present invention, as shown in figure 1, may include steps of:
S1:During air-conditioner start refrigerating operaton, the run time of indoor temperature T1, outdoor temperature T4 and compressor is detected,
And indoor temperature T1 is compared with the first decision content T1P, outdoor temperature T4 and the first judgement interval T4d-T4g.
S2:As T1 > T1P and T4d < T4 < T4g, compressor is run with first frequency Frg, and otherwise compressor is with second
Frequency Fg is run, wherein first frequency Frg > second frequency Fg.That is, when air-conditioner starts shooting refrigerating operaton, it is necessary to same
When meet indoor temperature T1 more than the first decision content T1P and outdoor temperature T4 positioned at first judge in interval when, compressor just with
First frequency Frg runs, as long as indoor temperature T1 is less than the first decision content T1P and/or outdoor temperature T4 and judges area beyond first
Between, compressor is run with second frequency Fg.
In inventive embodiment, second frequency Fg is running frequency of the air-conditioner under common refrigerating state, for reality
The rapid purpose of existing air-conditioner start refrigeration, frequencies of the first frequency Frg higher than air-conditioner under common refrigerating state (that is, the
Two frequencies Fg).
S3:When compressor with first frequency Frg run and run time as U1 after, be not up in the run time of compressor
Before total post-set time U2, when air-conditioner is detected and exits signal, compressor is run with second frequency Fg.
When the run time for being not detected by exiting signal and compressor in air-conditioner reaches total post-set time U2, compressor
Run with second frequency Fg.So as to understand that time U2 is the maximum duration that the compressor for setting works under first frequency Frg.
In other words, after with first frequency Frg operation a period of times, compressor is from first frequency Frg operations for compressor
Being transformed into situation about running with second frequency Fg has two kinds:A kind of situation is the time U1 that compressor is run with first frequency Frg
More than post-set time U2, in the run duration, and it is not detected by exiting signal;Although another kind of situation is compressor with the first frequency
The time U1 of rate Frg operation is without departing from post-set time U2, but detects and exit signal.
The control method of air-conditioner according to embodiments of the present invention, by indoor temperature T1 and the first decision content T1P, outdoor temperature
T4 is compared with the first judgement interval T4d-T4g, and when T1 > T1P and T4d < T4 < T4g is met, compressor is with the first frequency
Rate Frg is run, so as to reach the purpose for making room fast cooling.
Additionally, exiting letter when compressor is more than post-set time U2 or is detected with the time U1 that first frequency Frg runs
Number when, compressor machine with second frequency Fg run.Thereby ensure that compressor will not work in the state of long-time altofrequency,
Improve the service life of compressor.
In some embodiments of the invention, signal is exited for one or two the combination in the following two kinds condition:
Condition a:Indoor temperature T1 is less than the second decision content T1t;
Condition b:Outdoor temperature T4 judges interval T4d-T4g beyond first;
When signal is exited to combine, then when one of condition is met, compressor is run with second frequency Fg, wherein
Second decision content T1t≤the first decision content T1P, i.e. the second decision content T1t are not more than the first decision content T1P.
That is, be now divided into three kinds of situations, a kind of situation be air-conditioner set exit signal as indoor temperature T1
It is less than the second decision content T1t, then when in this case, when only detecting indoor temperature T1 less than the second decision content T1t, i.e., full
During sufficient condition a, compressor is run with second frequency Fg.Second situation be air-conditioner set exit signal as outdoor temperature T4
Interval T4d-T4g is judged beyond first, then in that case, only detect outdoor temperature T4 and judge interval beyond first
T4d-T4g, that is, when meeting condition b, compressor is run with second frequency Fg.
It is that indoor temperature T1 is less than the second decision content T1t and outdoor temp that the third situation is the signal that exits that air-conditioner sets
Combinations of the degree T4 beyond the first judgement interval T4d-T4g, then in that case, as long as detecting indoor temperature T1 less than second
When decision content T1t or outdoor temperature T4 exceed the first judgement interval T4d-T4g, compressor is run with second frequency Fg, also
It is to say, in that case, exits the combination that signal is condition a and condition b, in the mistake that compressor is run with first frequency Frg
Cheng Zhong, as long as meeting one of them in condition a and condition b, compressor is run with second frequency Fg.
Alternatively, the span of the difference between the second decision content T1t and the first decision content T1P is 1 DEG C~2 DEG C.
The control method of the air-conditioner according to the specific embodiment of the invention is described in detail with reference to Fig. 1.
The first step:User opens air-conditioner refrigerating operaton;
Second step:Temperature sensor detects indoor environment temperature T1, outdoor environment temperature T4;
3rd step:Whether T1 is judged higher than the first decision content T1P, if entering the 4th step, otherwise into the 9th step.
4th step:Judge that whether T4 judges interval T4d-T4g in first, if into the 5th step, otherwise into the
Nine steps.
5th step:Compressor is run into first frequency Frg, after remaining on time U1, into the 6th step;
6th step:Whether T1 is judged higher than the second decision content T1t, if entering the 7th step, otherwise into the 9th step.
7th step:Judge that whether T4 judges interval T4d-T4g in first, if into the 8th step, otherwise into the
Nine steps.
8th step:Whether first frequency Frg accumulated running times Ur is judged more than U2, if entering the 9th step, otherwise
Formed into the 5th step and circulated.
9th step:Compressor first frequency Frg accumulated running time Ur clear 0, compressor enter common cooling operation mode
Frequency is run.
