Operation stability reduces operation noise;When outdoor environment temperature is relatively low, the sendible temperature of human body is relatively low, therefore from
There is an urgent need to air-conditionings quickly to be heated by user when outdoor is got in, at this time according to the second fitting formula and the 4th fitting formula
The pass valve speed of calculated expansion valve and the raising frequency speed of compressor are relatively high, reach pre- in the time that electric heater is opened
The time that hot time and outer wind turbine are opened reaches the opening time in advance and expansion valve is according to the fast quick-closing valve of pass valve speed to target
When aperture, compressor highly shortened system according to the quick raising frequency of raising frequency speed so as to realize the quick heating of air-conditioning
The time of heat brings good usage experience for user.Also, through inventor's repetition test, observation is analyzed and is compared, adopting
In the case of carrying out quickly heating with technical scheme of the present invention, the raising frequency speed of air-conditioning can be promoted compared with the existing technology
Several times, even decades of times realize the jump frequency of air-conditioning.In addition, by making expansion valve opening be decreased to mesh before compressor start
Mark aperture, the aperture of expansion valve can also be made to be matched with compressor in compressor start, avoid expansion valve with compressor together
Expansion valve opening occurs with the bad situation of compressor matching degree caused by startup, further increases the system after compressor start
Thermal effect.

The third fitting formula of preceding opening time can be:tw=mRH+n, wherein twIndicate the opening time (s) in advance of outer wind turbine, RH
Indicate outdoor environment humidity (namely relative humidity, %), m is proportionality coefficient, and n is constant.The proportionality coefficient m of third fitting formula
It can be determined as follows with constant n:Assuming that the value range of outdoor environment humidity RH is 20-100%, RH is enabled as a result,
When=20%, opening time t in advancewminWhen=20s, RH=100%, opening time t in advancewmax=180s, is acquired, m=2, n
=-20, therefore tw=2RH-20.After calculating third fitting formula, third fitting formula is preset in the control system of air-conditioning
In system, so, after user selects heating mode every time, control system just can be true according to the outdoor environment humidity got
The opening time in advance of fixed outer wind turbine, and shift to an earlier date the outer wind turbine of opening time control with maximum (top) speed prior to compressor start according to this
Operation.
As shown in figure 5, in a kind of possible embodiment, there are one compressors the raising frequency stage, and the raising frequency rank
The raising frequency speed of outdoor environment temperature and compressor is inversely in 4th fitting formula of section, it is preferable that raising frequency speed is
Arbitrary value in 0.5Hz-30Hz.For example, the 4th fitting formula of raising frequency speed can be:vy=kTao+ b, wherein vy
Indicate the raising frequency speed (Hz/s) of compressor, TaoIndicate outdoor environment temperature (DEG C), k is proportionality coefficient, and b is constant.4th is quasi-
The proportionality coefficient k and constant b for closing formula can be determined as follows:Assuming that outdoor environment temperature TaoValue range be-
5-20 DEG C, T is enabled as a result,aoAt=20 DEG C, raising frequency speed vymin=0.5Hz/s, TaoAt=- 5 DEG C, raising frequency speed vymax=30Hz/
S is acquired, k=-1.18, b=24.1, therefore vy=-1.18Tao+24.1.After calculating the 4th fitting formula, the 4th is intended
It closes formula to be preset in the control system of air-conditioning, so, after user selects heating mode every time, control system just can root
The raising frequency speed of compressor is determined according to the outdoor environment temperature got, and according to the raising frequency speed control compressor raising frequency work
Make.
It further, can also be by outdoor environment temperature TaoValue range be divided into one or more temperature ranges,
Outdoor environment temperature TaoWhen falling into one of temperature range, corresponding raising frequency speed is calculated using the 4th fitting formula.For example,
By outdoor environment temperature TaoValue range be divided into three sections (- ∞, -5), [- 5,20] and (20 ,+∞), getting
Outdoor environment temperature TaoWhen in [- 5,20] this section, using the 4th fitting formula vy=kTao+ b calculates raising frequency speed,
As outdoor environment temperature TaoWhen in the section (- ∞, -5) or (20 ,+∞), then outdoor environment temperature is equal to -5 and 20 respectively

After the step of time runs, control method further includes:
According to the correspondence between outdoor environment temperature and the rotating speed of outer wind turbine, the rotating speed of outer wind turbine is adjusted.
2 outer rotation speed of fan control table (1) of table
Tao(℃) | ≤10 | 10-16 | ≥16 |
rw(r/min) | 1200 | 800 | 400 |
Wherein, TaoRepresent outdoor environment temperature, rwRepresent the rotating speed of outer wind turbine.
By above-mentioned control mode, the advantages of control method of air-conditioning of the invention, is:By in outdoor environment temperature
The first fitting formula, the second fitting formula, third fitting formula and the 4th fitting formula are predefined when less than temperature threshold, so
Electric heater is calculated in the preheating time of warm-up phase according to the first fitting formula afterwards, expansion valve is calculated according to the second fitting formula
In the pass valve speed for closing the valve stage, outer wind turbine is calculated according to third fitting formula and shifts to an earlier date the opening time in open stage in advance,
Calculate raising frequency speed of the compressor in the raising frequency stage according to the 4th fitting formula, so control outer wind turbine according to preheating time prior to
Compressor operating, expansion valve according to close valve speed close valve to reference opening amount, outer wind turbine according to the opening time in advance prior to compressor
Operation, and the time opened in electric heater reaches preheating time and electric expansion valve closes valve to the fortune of reference opening amount and outer wind turbine
The row time reaches control compressor when shifting to an earlier date the opening time and carries out raising frequency according to raising frequency speed, air-conditioning under heating mode of the invention
Control method can improve the universality of air-conditioning and the running stability of compressor, ensure the heating efficiency of air-conditioning, improve and use
The usage experience at family.
Specifically, first, the preheating time of outdoor environment temperature and electric heater inversely, winter outdoor environment
When temperature is relatively high, the lubricating oil viscosity consistency in compressor is relatively low, and lubricant effect is preferable, need not preheat at this time, compressor
Operation can normally be started, ensure the heating efficiency and operation stability of compressor.Winter outdoor environment temperature is relatively low
When, the lubricating oil viscosity consistency in compressor is higher, and lubricant effect is poor, calculates electric heater according to the first fitting formula at this time
Preheating time, electric heater according to the preheating time open and the lubricating oil in compressor is heated, fully to reduce
The viscosity of lubricating oil.The compressor start after the time that electric heater is opened reaches preheating time, to effectively improve pressure
The operation stability and heating effect of contracting machine.
Secondly, outdoor environment humidity and the opening time in advance of outer wind turbine are proportional, winter outdoor environment humidity phase
To it is relatively low when, outdoor unit is not easy frosting, at this time according to the calculated outer wind turbine of third fitting formula in advance the opening time compared with
Short, after outer wind turbine shifts to an earlier date unlatching very short time opening time according to this, compressor can start, and ensure the quick system of compressor
The thermal efficiency.When winter outdoor environment humidity is relatively high, outdoor unit is easy frosting, calculated according to third fitting formula at this time
The opening time in advance of outer wind turbine is longer, and outer wind turbine shifts to an earlier date opening time unlatching according to this, and the air near outdoor unit is in exogenous wind
Flow at high speed under the drive of machine is unfavorable for the formation of frost.After the time of outer fan operation reaches the opening time in advance, compressor
It can start, be sent out to be effectively prevented the case where air-conditioning heating efficiency drastically declines caused by the too early frosting of compressor
It is raw.
Again, outdoor environment temperature respectively with the raising frequency speed for closing valve speed and compressor of expansion valve inversely.
When outdoor environment temperature is relatively high, the sendible temperature of human body is also higher, thus it is from the outside into the room when user's control it is empty
Transfer in that the hope that quickly heats of row is not strong, and the hope that user's control air-conditioning is quickly heated is not strong, at this time basis
The raising frequency of the pass valve speed and compressor of second fitting formula and the 4th calculated expansion valve of fitting formula is relatively lower speed,
When the time that outer wind turbine is opened reaches the opening time in advance and expansion valve closes valve to reference opening amount according to the pass valve speed, compression
Machine carries out raising frequency according to the raising frequency speed, can improve expansion valve and compressor while ensureing the heating effect of air-conditioning
Operation stability reduces operation noise;When outdoor environment temperature is relatively low, the sendible temperature of human body is relatively low, therefore from
There is an urgent need to air-conditionings quickly to be heated by user when outdoor is got in, at this time according to the second fitting formula and the 4th fitting formula
The pass valve speed of calculated expansion valve and the raising frequency speed of compressor are relatively high, reach pre- in the time that electric heater is opened
The time that hot time and outer wind turbine are opened reaches the opening time in advance and expansion valve is according to the fast quick-closing valve of pass valve speed to benchmark
When aperture, compressor highly shortened system according to the quick raising frequency of raising frequency speed so as to realize the quick heating of air-conditioning
The time of heat brings good usage experience for user.
By making expansion valve opening be decreased to reference opening amount before compressor start, the aperture of expansion valve can also be made to exist
It is matched with compressor when compressor start, expansion valve opening and compressor caused by avoiding expansion valve from starting together with compressor
The bad situation of matching degree occurs, and further increases the heating effect after compressor start.It is determined and is pressed by outdoor environment temperature
The stable working frequency of contracting machine determines after closing valve to reference opening amount by electric expansion valve according to the target exhaust temperature of compressor
The aperture of electric expansion valve and after shifting to an earlier date the opening time by outer wind turbine with maximum (top) speed operation according to outdoor environment temperature and
Compressor operating frequency adjusts the rotating speed of outer wind turbine, and control method of the invention can also be compressor in compressor operating
The running environment to match is provided, the working efficiency and job stability of compressor are further increased, improves the operation effect of air-conditioning
Fruit.
Further, through inventor's repetition test, observation is analyzed and is compared and obtains, the oil spitting amount to compressor, electricity are passed through
The aperture of sub- expansion valve, the rotating speed of outer wind turbine and oil-liquid separator etc. are accurately controlled, and are ensureing compressor operating stabilization
Under the premise of, the raising frequency speed of compressor can be controlled steadily in 0.5-30Hz/s, and especially maximum raising frequency speed can reach
To surprising 30Hz/s.And those skilled in the art understand that, the raising frequency speed of compressor is mostly in the prior art
0.5-1Hz/s, few compressors can reach the raising frequency speed of the present invention when keeping steady operation.Thus, it is of the invention
The raising frequency speed of air-conditioning can be promoted several times, even decades of times by air-conditioning compared with the existing technology when quickly being heated, from
And realize the jump frequency of air-conditioning, significantly improve the usage experience of user.

For another example, the number of temperature range and endpoint value are not unalterable, those skilled in the art can be based on practical application scene into
Row adjustment, is such as further subdivided into multiple sections, each section corresponds to different fitting formulas etc. by the section of [- 5,20].Again
Such as, the rotating speed that outer wind turbine is run within the opening time in advance can also be other rotating speeds, as long as the rotating speed is conducive to prevent outdoor
Machine frosting.For another example, when outdoor environment humidity is relatively low, outer wind turbine can also be controlled and do not start and directly control compressor liter
Frequently, raising frequency speed and heating efficiency are further increased.For another example, due to air-conditioning frosting and outdoor environment temperature and outdoor environment humidity
There is relationship, therefore before calculating the opening time in advance of outer wind turbine, can also first be carried out according to outdoor environment temperature preliminary
Judgement, to improve, whether the judgement precision of frosting calculates such as when outdoor environment temperature is less than 5 DEG C according to the first fitting formula
Opening time etc. in advance of outer wind turbine.For another example, temperature threshold and preheating time can also be according to the differences of concrete application scene
It is adjusted.For another example, other apertures or the opening value near reference opening amount that target aperture can also be electric expansion valve, it is corresponding
When target aperture is less than reference opening amount, compressor can start raising frequency after electric expansion valve reaches target aperture on ground,
When target opening value is more than reference opening amount, compressor can start raising frequency before electric expansion valve reaches target aperture.For another example,
Electric expansion valve can also be according to the frequency and electric expansion valve of outdoor environment temperature and/or compressor after reaching reference opening amount
Correspondence between aperture is adjusted, and outer wind turbine can also be according to outdoor environment temperature and compressor after reaching maximum (top) speed
Frequency and the rotating speed of outer wind turbine between correspondence be adjusted (such as the following table 3).
3 outer rotation speed of fan control table (2) of table

For multiple raising frequency sub-stages, accordingly, each raising frequency sub-stage includes one the 4th fitting subformula, the 4th fitting subformula
Between can be coefficient difference, can also be the difference of formula.It is risen for example, the raising frequency stage of compressor may include three
Frequency sub-stage, each raising frequency sub-stage corresponding 4th fitting subformula is respectively vy1=k1Tao+b1、vy2=k2Tao+b2、vy3=
k3Tao+b3.After user selects heating mode, control system is fitted subformula and calculates according to each 4th respectively accordingly to be compressed
Then the raising frequency speed of each raising frequency sub-stage of machine controls compressor and is risen successively according to the raising frequency speed of each raising frequency sub-stage
Frequently.The relationship for such as calculating the raising frequency speed of three raising frequency sub-stages is vy1>vy2>vy3(certainly, which may be other
Such as vy1<vy2<vy3Deng), then controlling compressor raising frequency in such a way that raising frequency speed is gradually reduced, realize that air-conditioning quickly heats
While, ensure that compressor oil return is normal, is gradually reduced process noise, prolongs the service life.
