Embodiment
The preferred embodiment of the present invention described with reference to the accompanying drawings.It will be apparent to a skilled person that this
A little embodiments are used only for explaining the technical principle of the present invention, it is not intended that limit the scope of the invention.Although for example,
The present invention is to combine compressor to set the embodiment in two raising frequency stages to be described, but this setup is not one
Into constant, in the case of without departing from the principle of the invention, those skilled in the art can also apply the inventive method to other
Application scenarios, as compressor can also set three even more raising frequency stages.
With reference first to Fig. 1, Fig. 1 is the schematic flow sheet of the control method of air-conditioning under low humidity heating condition of the invention.
As shown in figure 1, in order to solve present in now air-conditioned start raising frequency control method because the raising frequency time is long and
The problem of causing quick heating effect difference, the invention provides a kind of control method of air-conditioning under low humidity heating condition, the control
Method mainly includes the following steps that：
S100, ambient humidity is obtained, the starting switch of air-conditioning is pressed such as user to be made air-conditioning start shooting and select heating mode
Afterwards, air-conditioning obtains ambient humidity by hygrometer or humidity sensor etc., and wherein ambient humidity can refer to the relative of outdoor environment
Humidity；
S200, ambient humidity no more than setting humidity when, the expansion valve opening of air-conditioning is adjusted to first object aperture,
Such as when ambient humidity is not more than a certain relative humidity, expansion valve opening is first decreased to benchmark from 480 steps according to pass valve speed
Aperture, then increase to first object aperture from reference opening amount according to Valve opening velocity, it is preferable that humidity is set as 60%, expansion valve
For electric expansion valve or other can control the expansion valve of aperture；
It should be noted that the aperture regulation of electric expansion valve is driven by stepper motor, stepper motor rotates most
Small angle range is referred to as a step, and therefore, the aperture regulation of electric expansion valve is typically all to be weighed by " step ".Such as expansion valve
Aperture is 200 steps.I.e. stepper motor drives expansion valve to turn to the 200th angular unit.Generally it is closed in air-conditioning
When, it is balance system pressure, expansion valve can all be in larger aperture, as expansion valve is closed in air-conditioning in the present invention
When aperture can be 480 steps.And reference opening amount is then according to operational mode setting and outdoor temperature and compressor frequency phase
The aperture answered, the setting of reference opening amount contribute to system pressure difference to establish, and realize air conditioner quickly cooling and speed heat.As benchmark of the present invention is opened
Degree can be 280 steps.That is, while outer blower fan starts, expansion valve opening is first from 480 steps according to closing valve speed such as
200P/s (i.e. 200 steps/second) is decreased to 280 steps, then increases to first object from 280 steps according to Valve opening velocity such as 40P/s again
Aperture (such as 400 steps).
S300, during expansion valve opening is adjusted to first object aperture, start the outer blower fan of air-conditioning, and press
According to setting acceleration raising speed to first object rotating speed, it is preferable that when expansion valve opening reaches reference opening amount, make outer blower fan by
Start according to the acceleration for improving 1000r/min each seconds, and the first object rotating speed for reaching 3000r/min at 3 seconds, preferably
Ground, first object rotating speed are the maximum functional rotating speed of outer blower fan；
S400, while outer blower fan starts raising speed, before or after, make the compressor start of air-conditioning, it is preferable that outside
While blower fan starts raising speed, make the compressor start of air-conditioning；
S500, making compressor, continuous raising frequency, such as after compressor start, makes compression stage by stage according to multiple setting speeds
Machine carries out raising frequency according to the first raising frequency speed, and the second raising frequency is immediately switched to after running to a certain frequency or after operation a period of time
Speed continues raising frequency；
S600, judge whether compressor frequency reaches first object frequency, such as obtain the current frequency of compressor in real time, and
By current frequency compared with first object frequency；
S700, when compressor frequency reaches first object frequency, make compressor stop raising frequency, such as reach in current frequency
During first object frequency, compressor is maintained first object frequency and work on.Preferably, first object aperture is and compression
The expansion valve opening that the first object frequency of machine matches, that is to say, that compressor start stage by stage continuous raising frequency to first
During target frequency, expansion valve opening also increases to first object aperture from reference opening amount just.
By foregoing description as can be seen that the control method of the air-conditioning of the present invention in ambient humidity by being not more than 60%
When, make expansion valve prior to compressor start, and make when expansion valve reaches reference opening amount compressor and outer blower fan while start, one
Aspect can make expansion valve opening match with working frequency during compressor start in advance, avoid expansion valve with compressor together
Expansion valve opening occurs with the unmatched situation of compressor caused by startup, on the other hand can make when ambient humidity is little
Compressor is actuated for raising frequency immediately, needs first to open outer fan radiating before eliminating compressor start (to avoid quick frosting)
The step of, the raising frequency time of compressor is further shorten, improves the heating effect after compressor start.And compressor is set to exist
With the control method of different raising frequency speed continuous raising frequency stage by stage after startup, then when can further shorten the raising frequency of compressor
Between, improve the heating effect after compressor start, and then the purpose quickly heated.In other words, present invention eliminates pressure
During contracting machine raising frequency in oil return frequency continuous service process, then opened by adjusting expansion valve opening to benchmark in advance
Spend, make compressor and outer blower fan while start, and control the mode of compressor raising frequency speed, ensure that the normal oil return of compressor
Simultaneously, additionally it is possible to complete the quick raising frequency of compressor, solve present in existing start raising frequency control method due to raising frequency
Caused by time length the problem of quick heating effect difference, the comfortableness of air-conditioning is improved, improves Consumer's Experience.
Certainly, first object rotating speed is not only limited to a kind of form of maximum functional rotating speed, can improve compressor heat sink strip
In the case of part, the first object rotating speed can be arranged to any rational numerical value by those skilled in the art, so that it meets
More specifical application scenarios, as first object rotating speed can also be close to outer blower fan maximum functional rotating speed a certain tachometer value or
The maximum (top) speed value that outer blower fan can reach under outer boundary's environment temperature.Similarly, the setting of ambient humidity is not only limited to
A kind of 60% mode, those skilled in the art can be adjusted based on different regions Different climate condition, such as dry
Area can be appropriate raising this numerical value, setting humidity is arranged to 65% or so, reduced the area of weather moistening is appropriate
This numerical value, setting humidity is arranged to 55% or so etc..
Referring to Fig. 2, principle of the invention is expanded on further.Wherein, Fig. 2 is empty under low humidity heating condition of the invention
The raising frequency process contrast schematic diagram of the compressor of the control method of tune and the compressor of prior art.In Fig. 2, solid line represents this hair
The raising frequency process of compressor in bright control method, dotted line represent the raising frequency process of compressor in the prior art.
Entered as shown in Fig. 2 in the prior art, as compressor start is latter using fixed raising frequency speed V (such as 1Hz/s)
Row raising frequency, and it is provided with the first oil return frequency f during raising frequency in order to ensure the normal oil return of compressor1With the second oil return
Frequency f2, when compressor raising frequency to the first oil return frequency f1When, the lubricating oil in compressor is in or will be in oil starvation state,
Therefore compressor maintains a period of time in this frequency, ensures to be further continued for continuing with raising frequency speed V after the stable oil return of compressor
Raising frequency.Similarly, in compressor raising frequency to the second oil return frequency f2, and a period of time is maintained in this frequency, ensure that compressor is steady
The follow-up frequency of continuing rising of oil return is determined, until compressor reaches peak frequency fmaxAfter stop raising frequency.As stated in the Background Art, such liter
Frequency mode is due in the first oil return frequency f1With the second oil return frequency f2A period of time is maintained, therefore has had a strong impact on compressor
Raising frequency speed, although ensure that the stable oil return of compressor, can not meet the needs of quickly heating well.
With continued reference to Fig. 2, as the preferred embodiment of the present invention, the continuous raising frequency process of compressor can be divided into two
The individual stage, wherein, first stage compressor is with the first raising frequency speed V1Raising frequency is carried out, second is entered when raising frequency to transition frequency
Stage.Second stage compressor is with the second raising frequency speed V2Raising frequency is carried out, during raising frequency to first object frequency, stops raising frequency.It is excellent
Selection of land, transition frequency could be arranged to the first oil return frequency f1.First raising frequency speed V1More than the second raising frequency speed V2, such as can be with
First raising frequency speed is arranged to 1.2Hz/s, the second raising frequency speed is arranged to 0.5Hz/s.
That is, in the control method of the present invention, S500 may further include following steps again：
S510, make compressor according to the first raising frequency speed V1Carry out raising frequency, as the control system of air-conditioning make compressor according to
1.2Hz/s raising frequency speed carries out raising frequency；
S520, judge whether compressor frequency reaches transition frequency, transition frequency is such as arranged to the first oil return frequency f1,
Control system judges whether the current frequency of compressor reaches the first oil return frequency f1；
S530, in compressor frequency reach transition frequency f1When, make compressor according to the second raising frequency speed V2Carry out raising frequency,
The current frequency for such as judging compressor in control system reaches f1When, make compressor continue to rise according to 0.5Hz/s raising frequency speed
Frequently, to ensure the stable oil return of compressor on the premise of continuous raising frequency, complete the quick heating of air-conditioning.
Preferably, transition frequency f1Less than first object frequency, and first object set of frequency is the maximum work of compressor
Working frequency fmax。
The advantages of above control method, is：By controlling the raising frequency speed during compressor raising frequency so that compressor
During with different raising frequency speed raising frequencies, the speed/rate for discharging the lubricating oil of compressor also correspondingly changes,
And then oil return speed/speed of oil return capillary is adapted to, ensure that the oil return of compressor is stable.Specifically, by making compressor
In transition frequency f1Change raising frequency speed, that is, carry out the controlling party of raising frequency in two stages with raising frequency speed first quick and back slow
Method so that compressor is with the first raising frequency speed V1During raising frequency, the speed/rate of the discharge compressor of lubricating oil is met or exceeded
Oil return speed/speed of oil return capillary, the lubricating oil in compressor gradually decrease.When reaching transition frequency f1When, compressor
Then according to the second raising frequency speed V2Raising frequency is carried out, the lubricating oil for now discharging compressor greatly reduces, lubricating oil discharge compression
The speed/rate of machine is less than oil return speed/speed of oil return capillary, and then the lubricants capacity in compressor is ensured.
That is the present invention can ensure the normal oil return of compressor by the change of raising frequency speed, while by cancelling in oil return frequency
The control mode of continuous running phases has correspondingly speeded up the raising frequency speed of compressor, enable compressor quickly raising frequency to most
Big working frequency, and then run with maximum operation frequency, meet the needs of user quickly heats.Reference picture 2 can significantly be seen
Go out, tested repeatedly through inventor, the time that compressor of the invention reaches maximum operation frequency considerably less than presses in the prior art
Contracting machine reaches the time of maximum operation frequency.
Method is preferably controlled it is pointed out that above-mentioned and concrete numerical value is used merely to illustrate the principle of the present invention, and
It is not intended in limiting the scope of the invention, on the premise of without departing from the principle of the invention, those skilled in the art can be with
Any form of adjustment is done to above-mentioned parameter, as long as the technical scheme after adjustment can ensure the premise of the normal oil return of compressor
The lower condition for improving raising frequency speed.Such as the raising frequency stage further can also be divided into three phases, each stage is with difference
Raising frequency speed (the fast mode of such as speed) carry out raising frequency；Transition frequency according to the first oil return frequency can also float downward
It is dynamic；The maximum operation frequency of the uncompressed machine of first object frequency, but value close to maximum operation frequency etc..
In addition, preferably to improve the experience that user uses air-conditioning, when compressor is worked with maximum operation frequency, this hair
The control method of bright air-conditioning can also comprise the following steps：
S800, ambient parameter is obtained, such as obtain current environment temperature (such as indoor temperature)；
S900, reach in ambient parameter/close to target component when, compressor is downconverted to the second target frequency, make simultaneously
The rotating speed of outer blower fan is reduced to the second rotating speed of target, expansion valve opening is decreased to the second target aperture, and such as temperature reaches indoors
The target temperature of user's setting or during close to target temperature, makes compressor be downconverted to rated operation frequency or be reduced to and extraneous ring
The working frequency that border temperature matches, while the rotating speed of outer blower fan is reduced to nominal operation rotating speed or is matched with compressor
Working speed, and the aperture of expansion valve is decreased to the aperture to match with the present operating frequency of compressor.
So have the advantage that：After air-conditioning quickly heats a period of time, indoor temperature can rise accordingly, work as room
Interior temperature reaches/close to user's setting temperature when, compressor does not just have to continue to operate in maximum operation frequency, and outer blower fan is natural
Radiated without maximum (top) speed is operated in, expansion valve is without being operated in the first object aperture matched with compressor.
At this moment compressor is downconverted to rated operation frequency or the working frequency more matched with current outdoor environment (such as outdoor temperature),
And the rotating speed of outer blower fan is reduced to nominal operation rotating speed or the rotating speed to match with compressor, and the aperture by expansion valve
Be decreased to the aperture to match with compressor, can not only ensure the normal work of air-conditioning, and effectively extend compressor,
The working life of outer blower fan and expansion valve.
