In a kind of possible embodiment, preferably to improve the experience that user uses air-conditioning, heating effect is promoted, is carried
The step of job stability and service life of high compressor, control electric expansion valve is according to valve speed pass valve to target aperture is closed
Later, control method further includes：
The aperture of electric expansion valve is adjusted according to the target exhaust temperature of compressor.
By above-mentioned control mode, the advantages of control method of air-conditioning of the invention, is：It is quasi- by predefining first
Formula, the second fitting formula and third fitting formula are closed, is then opened in advance according to according to the outer wind turbine of the first fitting formula calculating
The opening time in advance in stage is opened, the second fitting formula calculates expansion valve in the pass valve speed for closing the valve stage, is fitted according to third
Formula calculates raising frequency speed of the compressor in the raising frequency stage, and then controls outer wind turbine and transported prior to compressor according to the opening time in advance
Row, expansion valve reach opening time in advance and electricity according to valve speed pass valve is closed to reference opening amount, and in the time of outer fan operation
Control compressor carries out raising frequency according to raising frequency speed when sub- expansion valve closes valve to reference opening amount, air-conditioning under heating mode of the invention
Control method can improve the universality of air-conditioning, ensure the heating efficiency of air-conditioning, improve the usage experience of user.
Specifically, first, outdoor environment humidity and the opening time in advance of outer wind turbine are proportional, ring outside winter room
When border humidity is relatively low, outdoor unit is not easy frosting, at this time opening in advance according to the calculated outer wind turbine of the first fitting formula
It is shorter to open the time, and outer wind turbine shifts to an earlier date according to this after the opening time opens very short time, and compressor can start, and ensure compressor
Quick heating efficiency.When winter outdoor environment humidity is relatively high, outdoor unit is easy frosting, at this time according to the first fitting formula
The opening time in advance of calculated outer wind turbine is longer, and outer wind turbine shifts to an earlier date the opening time prior to compressor unlatching, outdoor according to this
Air near the machine flow at high speed under the drive of outer wind turbine, is unfavorable for the formation of frost.Reach in the time of outer fan operation and carries
After the preceding opening time, compressor can start, to be effectively prevented the air-conditioning heating caused by the too early frosting of compressor
The case where efficiency drastically declines improves the efficiency quickly heated, improves user experience.
Secondly, 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
It is not strong to transfer in the hope that row quickly heats, at this time according to the second fitting formula and the calculated expansion valve of third fitting formula
The raising frequency for closing valve speed and compressor it is relatively lower speed, outer wind turbine shifts to an earlier date opening time and expansion valve with maximum (top) speed operation
When closing valve to reference opening amount according to the pass valve speed, compressor carries out raising frequency according to the raising frequency speed, can ensure air-conditioning
While heating effect, improves the operation stability of expansion valve and compressor, reduces operation noise；It is opposite in outdoor environment temperature
When relatively low, the sendible temperature of human body is relatively low, thus it is from the outside into the room when user there is an urgent need to air-conditionings quickly to be heated,
At this time according to the raising frequency speed of pass the valve speed and compressor of the second fitting formula and the calculated expansion valve of third fitting formula
Relatively high, outer wind turbine reaches the opening time in advance according to the time run with maximum (top) speed and expansion valve is according to the pass valve speed
When fast quick-closing valve to reference opening amount, compressor is according to the quick raising frequency of raising frequency speed, so as to realize the quick heating of air-conditioning,
The time of heating is highly shortened, good usage experience is brought 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, by outer wind turbine with maximum (top) speed operation shift to an earlier date the opening time after according to outdoor environment temperature and pressure
Contracting machine working frequency adjusts the rotating speed of outer wind turbine and by the mesh according to compressor after the valve to reference opening amount of electric expansion valve pass
Mark delivery temperature determines that the aperture of electric expansion valve, 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

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 parameter of the first fitting formula, the form of the second fitting formula and third fitting formula and air-conditioning can be based on not
Same application scenarios are adjusted, if third fitting formula can also be vy=kTao+b(0<k<1) etc..For another example, temperature range
Number and endpoint value are not unalterable, and those skilled in the art can be adjusted based on practical application scene, such as incite somebody to action [- 5,
20] section is further subdivided into multiple sections, and each section corresponds to different fitting formulas etc..For another example, outer wind turbine is in advance
The rotating speed run in opening time can also be other rotating speeds, as long as the rotating speed is conducive to prevent outdoor unit 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 raising frequency, further increase liter
Frequency speed and heating efficiency.For another example, since air-conditioning frosting and outdoor environment temperature and outdoor environment humidity have relationship,
Before the opening time in advance for calculating outer wind turbine, can also preliminary judgement first be carried out according to outdoor environment temperature, with raising whether
The judgement precision of frosting calculates the unlatching in advance of outer wind turbine according to the first fitting formula such as when outdoor environment temperature is less than 5 DEG C
Time etc..For another example, other apertures or the opening value near reference opening amount that target aperture can also be electric expansion valve, accordingly
When target aperture is less than reference opening amount, compressor can start raising frequency after electric expansion valve reaches target aperture, in mesh
When marking opening value more than reference opening amount, compressor can start raising frequency before electric expansion valve reaches target aperture.For another example, electric
Sub- expansion valve can also opening according to the frequency and electric expansion valve of outdoor environment temperature and/or compressor after reaching reference opening amount
