Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the control method of operation of air conditioner frequency of the present invention and system are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In one embodiment, as shown in Figure 1, provide a kind of control method of operation of air conditioner frequency, the method comprises:
S100, detects the indoor environment temperature T of air-conditioning
inner ringwith outdoor environment temperature T
outer shroud.
S200, according to indoor environment temperature T
inner ringwith outdoor environment temperature T
outer shroudobtain the initial launch frequency F of air-conditioning.
S300, obtains the temperature drop rate d Δ t/d (1 DEG C) of air-conditioning, and judges whether temperature drop rate is more than or equal to default temperature drop rate t.
S310, if so, then carries out negative correction to initial launch frequency F, obtains the first running frequency F+F

-run.
S320, if not, then just revises initial launch frequency F, obtains the second running frequency F+F
+, and control air-conditioning according to the second running frequency F+F
+run.
At present, the control method of operation of air conditioner frequency has 3 kinds substantially: frequency segmentation position control, and frequency PI controls and frequency ambiguity controls.Wherein, frequency segmentation position control can only according to the change of indoor environment temperature section, is operated by the several frequencies controlling compressor of air conditioner, cannot meet air-conditioning cold flow export with room refrigeration requirement mate requirement, gradually eliminate out market.The cold that frequency PI controls to produce at different frequencies because of convertible frequency air-conditioner is non-linear, its cold and change of frequency and variations in temperature have much relations, when compressor high frequency operates, temperature in room can have a greater change, easily cause the fluctuation up and down of room temperature, thus occur that in room, temperature is partial to the phenomenon of design temperature side for a long time, is therefore also eliminated gradually.Although frequency ambiguity controls to control temperature in room more accurately reach design temperature, but in room temperature and the design temperature temperature difference larger, only considered temperature drop rate, and have ignored the adaptability of human body, therefore easily make people cause air conditioner disease, especially the weakling such as children, pregnant woman, old man more easily causes air conditioner disease.
In the present embodiment, when detection of air-conditioning is to anti-air conditioner disease mode signal, air-conditioning enters " anti-air conditioner disease pattern " (also can other patterns of called after, as " temperature drop control model "), and temperature-detecting device (as temperature sensor) detects the indoor environment temperature T of air-conditioning
inner ringwith outdoor environment temperature T
outer shroud, according to indoor environment temperature T
in ringwith outdoor environment temperature T
outer shroudobtain the initial launch frequency F of air-conditioning, air-conditioning brings into operation according to initial launch frequency F, and air-conditioning, in running, detects the temperature drop rate V obtaining air-conditioning in real time, and judges whether temperature drop rate is more than or equal to default temperature drop rate V
preset, if so, then negative correction is carried out to initial launch frequency F, obtains the first running frequency F+F
-, and control air-conditioning according to the first running frequency F+F
-run, if not, then negative correction is carried out to initial launch frequency F, obtain the second running frequency F+F
+, and control air-conditioning according to the second running frequency F+F
+run.Wherein, F
+represent that one of air-conditioning frequency on the occasion of, F
-represent a negative value of air-conditioning frequency.
Whether the control method of the present embodiment hollow allocation and transportation line frequency is more than or equal to default temperature drop rate V according to temperature drop rate V
presetrevise the running frequency of air-conditioning, by the research to frequency-conversion air-conditioning system, find that operation of air conditioner frequency is higher, refrigerating capacity is more, and temperature drop rate is also faster, and operation of air conditioner frequency is lower, and refrigerating capacity is fewer, and temperature drop rate is slower.As temperature drop rate V>=V
presettime, illustrate that the temperature drop rate of now air-conditioning is very fast, according to fuzzy control theory, negative correction is carried out to the running frequency of air-conditioning, operation of air conditioner frequency is reduced in preset range, thus temperature drop rate is decreased, but can not reduce too many.If temperature drop rate V < is V
in advance iftime, illustrate that the temperature drop rate of now air-conditioning is slower, just revise according to the running frequency of fuzzy control theory to air-conditioning, operation of air conditioner frequency is increased in preset range, thus temperature drop rate is increased to some extent, but can not increase too many, temperature drop rate is made to be within the scope of the relatively more suitable temperature drop rate of user weaklings such as (especially) children, pregnant woman, old men all the time, user can not cause air conditioner disease because of adapting to temperature drop rate, thus effectively reduces the incidence of disease of air conditioner disease.
Wherein, temperature drop rate V can be defined as d Δ T/d (1min), i.e. the size of variations in temperature in the unit interval, and now presetting temperature drop rate is V
preset, represent that the temperature of decline per minute is the optimum temperature drop rate of human body.In another embodiment, also temperature drop rate can be represented with d Δ t/d (1 DEG C), d Δ t/d (1 DEG C) represents that temperature often changes 1 DEG C of time spent, represent that as d Δ t/d (1 DEG C) >=t current temperature drop rate is comparatively slow, just can revise the initial launch frequency of air-conditioning; Represent that as d Δ t/d (1 DEG C) < t current temperature drop rate is very fast, can carry out negative correction to the initial launch frequency of air-conditioning, wherein, t represents the default temperature drop time.Preset temperature drop rate V
presetbe according to current fuzzy control temperature drop rate, and children's heat dissipation capacity probably account for the optimum temperature drop rate of weakling such as children under each indoor environment temperature interval that 75% of adult's heat dissipation capacity obtains by experiment.Fuzzy control theory refers to the concrete numerical value without the need to knowing when running frequency is revised, and what adapt to according to demand adjusts accordingly.
Preferably, in one embodiment, according to indoor environment temperature T
inner ringwith outdoor environment temperature T
outer shroud, obtain air-conditioning initial launch frequency F by inquiring about default initial launch frequency meter (table 1).Preset initial launch frequency meter to be stored in advance in air-conditioning, to obtain the indoor environment temperature T of air-conditioning
inner ringwith outdoor environment temperature T

outer shroud, (T'2, T'3] in scope, the indoor environment temperature detected is T
inner ring, (T3, T4] in scope, then the initial launch frequency that just can obtain air-conditioning according to table 1 is F8.Similar, as long as outdoor environment temperature and the indoor environment temperature of air-conditioning detected, just corresponding initial launch frequency F can be obtained according to table 1.
Preferably, in one embodiment, by detecting indoor environment temperature in real time, and the time that counting chamber environment variations in temperature spends, obtain the temperature drop rate of air-conditioning.In this embodiment, indoor environment temperature records, and only need record the temperature drop rate that a time parameter just can obtain air-conditioning again, required parameter is less, and it is comparatively easy to implement, and the method is also easy to realize.
In one embodiment, see Fig. 2, also comprise:
S001, obtains the design temperature T of air-conditioning
if, and according to design temperature T
ifobtain corresponding dew-point temperature T

-+ F
+', and control air-conditioning according to the 3rd running frequency F+F
-+ F
+' run;
S420a, if not, then controls air-conditioning according to the first running frequency F+F
-run.
After air-conditioning enters " anti-air conditioner disease pattern ", obtain the design temperature T of the air-conditioning of user's setting
if, each design temperature T
ifunder all to the relative humidity that human body should be had pleasant
human body is at this design temperature T
ifand this design temperature T

corresponding dew-point temperature T can be obtained
dew point.Concrete, can according to design temperature T
ifinquiry is preset dew-point hygrometer (table 2) and is obtained corresponding dew-point temperature T
dew point.Wherein preset dew-point hygrometer by testing acquisition in advance, and be stored in air-conditioning.
Table 2
Associative list 2 is described in detail, when after the design temperature obtaining air-conditioning, if design temperature is T
if 1, compare with the design temperature in table 2, just can obtain this design temperature T
if 1under comparatively comfortable relative humidity
and the dew-point temperature T that this relative humidity is corresponding
dew point 1, pipe temperature and this dew-point temperature T in then detection being obtained
dew point 1compare, thus the running frequency of air-conditioning is finely tuned, to meet the comfort level demand of human body to humidity.Similar, when obtaining other design temperatures, just can obtain corresponding dew-point temperature according to table 2, and then reach air-conditioning frequency is adjusted, reach the effect of human body humidity comfort level demand.
The control method of the present embodiment hollow allocation and transportation line frequency, obtains design temperature T
ifafter, preset dew-point hygrometer and obtain design temperature T
ifcorresponding dew-point temperature T
dew pointfinely tune to ensure that interior pipe temperature maintains more than dew-point temperature corresponding to indoor environment humidity (dew-point temperature is the humidity that human body is comparatively suitable for) by the running frequency of magnitude relationship to air-conditioning of interior pipe temperature and dew-point temperature, even if indoor environment humidity maintains in the suitable humidity range of human body, air-conditioning is made to meet under suitable temperature drop rate, also meet suitable humidity, improve human comfort further.The running frequency that above-mentioned control method controls air-conditioning takes into account temperature drop rate and humidity requirement, not only ensure the temperature drop rate that human body is suitable, and ensure that the moisture requirement that human body is suitable, further improve the comfort of air-conditioning, reduce the incidence of disease of air conditioner disease, and the method is by automatic air conditionning, do not increase any cost, simple to operate, easy to use, safety and Health is comfortable.
What deserves to be explained is, when controlling the running frequency of air-conditioning, the priority controlling operation of air conditioner frequency according to temperature drop rate is greater than the priority controlling operation of air conditioner frequency according to the size of interior pipe temperature and dew-point temperature.Such as: when controlling the running frequency of air-conditioning, if need according to temperature drop rate the running frequency improving air-conditioning, and the running frequency reducing air-conditioning is needed according to interior pipe temperature and dew-point temperature, then preferentially raise the running frequency of air-conditioning, preferentially to ensure that temperature drop rate meets the comfort level requirement of weakling.
