Wherein, TaoRepresent outdoor environment temperature, rwRepresent the rotating speed of outer wind turbine.
By above-mentioned control mode, under refrigeration mode of the invention the advantages of control method of air-conditioning be：By advance
It determines fitting formula, raising frequency speed of the compressor in the raising frequency stage is then calculated according to fitting formula, and then control compressor and press
According to raising frequency speed progress raising frequency, the control method of air-conditioning can improve the universality of air-conditioning under refrigeration mode of the invention, improve
The usage experience of user.Specifically, the raising frequency speed of outdoor environment temperature and compressor is proportional.In outdoor environment temperature
When spending relatively low, the sendible temperature of human body is relatively low, thus it is from the outside into the room when user's control air-conditioning carry out fast-refrigerating
Hope it is not strong, be relatively low at this time according to the raising frequency speed of the calculated compressor of fitting formula, compressor according to
The raising frequency speed carries out raising frequency, can reduce noise while ensureing the refrigeration effect of air-conditioning；It is opposite in outdoor environment temperature
When higher, the sendible temperature of human body is higher, thus it is from the outside into the room when user there is an urgent need to air-conditioning carry out fast-refrigerating, this
When it is relatively high according to the raising frequency speed of the calculated compressor of fitting formula, compressor according to the raising frequency speed carry out raising frequency,
It can make air-conditioning fast-refrigerating, highly shortened the time of refrigeration, good usage experience is brought for user.Pass through outdoor ring
The parameters such as border temperature and compressor operating frequency correspond to determine the stable working frequency of compressor, electric expansion valve aperture and
The rotating speed of outer wind turbine, control method of the invention can also provide the operation ring to match for compressor in compressor operating
Border further increases the working efficiency and job stability of compressor, improves the operational effect of air-conditioning.
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 carrying out fast-refrigerating, from
And realize the jump frequency of air-conditioning, significantly improve the usage experience of user.
Certainly, the above embodiment is used only for the principle illustrated the present invention, it is not intended that in the limitation present invention's
Protection domain, under conditions of without departing from the principle of the invention, those skilled in the art can also do arbitrary form to above-mentioned parameter
Adjustment, as long as the technical solution after adjustment can improve the condition of raising frequency speed under the premise of ensureing compressor normal oil return
?.For example, the form of fitting formula and the parameter of air-conditioning can be adjusted based on different application scenarios, such as fitting formula
Can also be vy=kTao 2+ b etc..For another example, the number of temperature range and endpoint value are not unalterable, and those skilled in the art can
It is adjusted with being based on practical application scene, the section of [16,40] is such as further subdivided into multiple sections, each section corresponds to
Different fitting formulas etc..For another example, the aperture of electric expansion valve can also according to the frequency of outdoor environment temperature or compressor with
Correspondence between the aperture of electric expansion valve is adjusted, and the rotating speed of outer wind turbine can also be according to outdoor environment temperature and pressure
Correspondence between the frequency of contracting machine and the rotating speed of outer wind turbine is adjusted (such as the following table 4).
4 outer rotation speed of fan control table (2) of table
Wherein, TaoOutdoor environment temperature is represented, f represents the working frequency of compressor, rwRepresent the rotating speed of outer wind turbine.
In addition, further to promote the refrigeration effect of air-conditioning, the raising frequency stage of compressor can also further be segmented
For multiple raising frequency sub-stages, accordingly, each raising frequency sub-stage includes a fitting subformula, and being fitted between subformula can be with
The only difference of coefficient can also be the difference for being fitted subformula.For example, the raising frequency stage of compressor may include three raising frequencies
Sub-stage, the corresponding fitting subformula of each raising frequency sub-stage is respectively vy1=k1Tao+b1、vy2=k2Tao+b2、vy3=k3Tao+
b3.After user selects refrigeration mode, control system calculates accordingly each of compressor according to each fitting subformula respectively
Then the raising frequency speed of raising frequency sub-stage controls raising frequency speed successively raising frequency of the compressor according to each raising frequency sub-stage.Such as meter
The relationship for 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, while realizing air-conditioning fast-refrigerating, protect
It is normal to demonstrate,prove compressor oil return, is gradually reduced process noise, prolongs the service life.
With reference to Fig. 1 and Fig. 2, brief Jie is done to a kind of workflow of the air-conditioning of the control method of the application present invention
It continues.The course of work of air-conditioning can be：
