The present embodiment mainly runs on precision air conditioner, and precision air conditioner is a kind of unit type air conditioner, in actual motion
In the process, the adjusting of indoor environment is realized by the aperture of adjusting electric expansion valve and the running frequency of compressor.Wherein, empty
Whether adjusting system has raising frequency demand, can be determined according to operational mode set by user, if user sets air-conditioning converting operation,
In refrigeration cycle, when room temperature is much higher than set temperature, air-conditioning system needs raising frequency, so that indoor environment temperature is rapidly achieved
Set temperature；In heating circulation, when room temperature is far below set temperature, air-conditioning system needs raising frequency, so that indoor environment
Temperature is rapidly achieved set temperature.Alternatively, when air-conditioning is just opened, when operating condition is unstable, in order to enable indoor environment temperature is fast
Speed reaches set temperature, and air-conditioning system generally all carries out raising frequency operation.Alternatively, user reduces setting during operation of air conditioner
When temperature, due to the temperature difference of indoor environment temperature and set temperature, system starts raising frequency, wherein the temperature difference at 3 DEG C or more, because

When length is greater than the first preset duration, the operation of the regulating power and compressor of the electric expansion valve of decision-making system is mismatched,
The case where system fluctuates adjusts the raising frequency rate of the compressor and opening for the electric expansion valve at this time, it may be necessary to link
Valve rate.
The specific linkage adjusts the mode of the raising frequency rate of the compressor and the valve opening rate of the electric expansion valve
There are many, the valve opening rate of raising frequency rate and electric expansion valve is such as reduced simultaneously according to a certain percentage, so that electric expansion valve
Regulating power and system compressors Operating match；Or when preventing electric expansion valve toning, compressor is opened by intermittent
The mode stopped, so that the Operating match of the regulating power of electric expansion valve and system compressors, such as reduces the raising frequency speed of compressor
Rate for a period of time after, run according to current frequency, and the valve opening rate of electric expansion valve continues to reduce, and is reduced to electronic expansion
When the Operating match of the regulating power of valve and compressor, control electric expansion valve is worked with current aperture.It is understood that pressure
The linkage regulative mode of the valve opening rate of the raising frequency rate and electric expansion valve of contracting machine not just for the above-mentioned embodiment enumerated,
As long as meet linkage adjusting, the regulating power of electric expansion valve and the Operating match of compressor, so that system fluctuation is lesser
Technical solution is protection scope of the present invention.
The present embodiment uses the method that electric expansion valve and compressor carry out linkage adjusting, is reducing electric expansion valve
On the basis of adjusting valve speed, while extending the raising frequency time of compressor, avoid electronic expansion valve regulation it is too fast caused by system
Excessive discharge temperature phenomenon caused by fluctuation or electronic expansion valve regulation are excessively slow.It adjusts in addition, the application links by extending electricity
Sub- expansion valve regulating time, avoids system parameter state hysteresis in the generation of adjustment state, to solve evaporator outlet production
Raw returns liquid phenomenon, finally avoids the generation of system fluctuation.Meanwhile it linking and adjusting the two big components for passing through refrigeration system simultaneously
Cold medium flux control is carried out, has many advantages, such as response speed faster, control precision is higher.
There are raising frequency demand, and the target of the suction superheat of compressor and electric expansion valve in air-conditioning system in the present embodiment
When the difference of the degree of superheat is greater than the buffer threshold of electric expansion valve, is linked and adjusted according to the duration of air-conditioning current operating conditions
The raising frequency rate of the compressor and the rate of electric expansion valve, so that the operation of the regulating power and compressor of electric expansion valve
Matching, realizing air-conditioning, system fluctuation is small in the process of running, avoids electric expansion valve toning, showing for liquid occurs back in evaporator outlet
As occurring.
Referring to Fig. 3, the present invention provides a kind of air-conditioning system adjusting method second embodiment, is based on above-mentioned reality shown in Fig. 2
Apply example, the present embodiment linkage adjust compressor raising frequency rate and electric expansion valve valve opening rate when, electronics in order to prevent
Expansion valve toning, by the way of reducing the raising frequency rate of compressor and the valve opening rate of electric expansion valve simultaneously, meanwhile, compression
In the raising frequency rate reduction of machine, by the way of intermittent start and stop, electric expansion valve persistently reduces the mode of valve opening rate,
So that the regulating power of electric expansion valve and the Operating match of compressor, in addition, the tune by way of the intermittent raising frequency of compressor
The advantages such as section cold medium flux, has control logic simple, and implementation difficulty is low.Meanwhile interval raising frequency process can mitigate compressor
Operation load, improves compressor service life.Specifically, being adjusted in program operation process in air-conditioning system, described in execution
When the step of the valve opening rate of the raising frequency rate and electric expansion valve of the linkage adjusting compressor, comprising:
Step S310, reduces the raising frequency rate of the compressor, while reducing the valve opening rate of the electric expansion valve,
In, when stopping reducing the raising frequency rate of the compressor, continue the valve opening rate for reducing the electric expansion valve.
It is understood that linkage adjusts the raising frequency rate of the compressor and the valve opening rate process of electric expansion valve
In, the valve opening rate of the raising frequency rate and electric expansion valve that reduce the compressor at the same time for a period of time after, pass through stop drop
The raising frequency rate of low compressor continues the valve opening rate for reducing electric expansion valve, achievees the purpose that prevent electric expansion valve toning.
Specifically, Fig. 4 is the flow diagram that Fig. 3 is further refined referring to Fig. 4, the specific raising frequency speed for illustrating compressor
How rate and the valve opening rate of electric expansion valve link adjusting, such as described raising frequency rate for reducing compressor, while described in reducing
The step of valve opening rate of electric expansion valve includes:
Step S311, the duration be greater than the first preset duration, and be less than or equal to the second preset duration when, drop
The raising frequency rate of the low compressor, and reduce the valve opening rate of the electric expansion valve.
Wherein, first preset duration is less than second preset duration.
Namely the difference of the target superheat degree in the suction superheat and electric expansion valve of the compressor is swollen greater than electronics
The duration of the buffer threshold of swollen valve be greater than the first preset duration, and be less than or equal to second preset duration when, simultaneously
Reduce the raising frequency rate of compressor and the valve opening rate of electric expansion valve, the adjusting of compressor described in during which not start and stop.
Step S312, when the duration is greater than second preset duration, the compressor is solid with current frequency
Fixed operation, electric expansion valve continue to adjust with current valve opening rate.
Namely the difference of the target superheat degree in the suction superheat and electric expansion valve of the compressor is swollen greater than electronics
The duration of the buffer threshold of swollen valve be greater than the second preset duration when, open the intermittent start and stop of compressor, at this time compressor with
The fixed operation of the frequency currently adjusted, stops frequency reducing, and electric expansion valve continuation continues to adjust with current valve opening rate, base
In the valve opening rate for reducing electric expansion valve in the first preset duration, in the second preset duration, continue with opening after reducing
Valve rate adaptation, more initial valve opening rate is low, therefore continues with the valve opening rate adaptation electric expansion valve after currently reducing, and electronics is swollen
The aperture regulation of swollen valve is slower, can prevent electric expansion valve toning.
The electric expansion valve was continued with current valve opening rate after the step of adjusting aperture, further includes:
Step S313, the electric expansion valve are continued after adjusting preset interval with current valve opening rate, are stopped described in adjusting
The aperture of electric expansion valve.
Namely after compressor stops frequency reducing prefixed time interval, also stop the valve opening rate for reducing electric expansion valve, and
Electric expansion valve is controlled to run with current aperture.After compressor stops frequency reducing prefixed time interval, stop adjusting the electricity
The aperture of sub- expansion valve prevents electric expansion valve regulating power too small, leads to the adjusting of electric expansion valve and the operation of compressor
It mismatches.Wherein, preset interval is different with specific reference to different air-conditioning types, determines with specific reference to experience and test, such as pre-
It is differed if being spaced in 3-15 seconds.
Further, after the aperture for stopping the adjusting electric expansion valve, the air-conditioning system adjusting method further include:
Step S314, when air-conditioning is greater than third preset duration with the duration that current aperture and current frequency are run,
Judging air-conditioning, whether there are also raising frequency demands；
In air-conditioning, there are also when raising frequency demand, then return to execute the suction superheat and electric expansion valve for obtaining compressor
Target superheat degree difference the step of, until compressor complete raising frequency until.
Step S315, when air-conditioning is without raising frequency demand, control compressor is run in a manner of initial launch, the electronic expansion
Valve is adjusted with initial regulative mode.
Alternatively, air-conditioning has raising frequency demand, but the difference of the target superheat degree of the suction superheat and electric expansion valve of compressor
When value is less than or equal to the buffer value of electric expansion valve, control compressor is run in a manner of initial launch, the electric expansion valve
With the adjusting of initial regulative mode.
It is less than or equal to electricity in the difference for the target superheat degree for having raising frequency demand or suction superheat and electric expansion valve
When the buffer value of sub- expansion valve, control compressor is run in a manner of initial launch, and the electric expansion valve is with initial regulative mode
It adjusts, the incidence relation of uncompression machine and electric expansion valve, control compressor is run in a manner of initial launch, electric expansion valve
With the adjusting of initial regulative mode, it is ensured that air-conditioning can be run according to imposing a condition, it is ensured that indoor environment meets user demand.
In addition, the present invention provides air-conditioning system adjusting method 3rd embodiment, the present embodiment is based on above-mentioned first and second
The step of embodiment, the valve opening rate for reducing the electric expansion valve includes:
Extend the regulating cycle of the electric expansion valve and/or reduce the adjusting step number of electric expansion valve in regulating cycle,
To reduce the valve opening rate of the electric expansion valve.
In above-described embodiment, the mode of the raising frequency rate of compressor is reduced mainly by way of system debug, according to
Empirical value debugs raising frequency rate, the most matched raising frequency rate of regulating power of operational effect and electric expansion valve is obtained, with the liter
Frequency rate adjusts the running frequency of compressor.
In above-described embodiment, electric expansion valve is by changing electric expansion valve period, the phases such as proportionality coefficient and integral constant
Parameter is closed to reduce the valve opening rate of the electric expansion valve, the regulating cycle of electric expansion valve and/or reduction as described in extension
The adjusting step number of electric expansion valve in regulating cycle.
Specifically, the calculation of the adjusting step number of the electric expansion valve in electric expansion valve regulating cycle is as follows:
U (t)=K*[e (t)-e (t-1)]+K* (T/a) * e (t)；
Wherein, u (t) is electronic expansion valve regulation step number；K is suction superheat proportionality coefficient；E (t) is degree of superheat deviation
Value；T is the regulating cycle of electric expansion valve；A is suction superheat integration time constant, and the K value and a value are according to experience
And the constant coefficient of determination according to different air-conditioning systems.
Based on degree of superheat deviation e (t)=SH (t)-target superheat degree-buffer threshold, the suction superheat of different moments is not
Meanwhile degree of superheat deviation is also different, suction superheat is smaller, and degree of superheat deviation is smaller, therefore the adjusting step number of electric expansion valve is got over
It is few.Wherein, the suction superheat SH (t) of t moment=Th-Thb, Th are suction temperature, and Thb is obtained according to pressure of inspiration(Pi) P0
Corresponding saturation temperature, suction temperature Th and pressure of inspiration(Pi) P0 can detect in real time or periodically acquisition by check device.
Further, the present embodiment enumerates T moment degree of superheat deviation value calculating method:
Work as suction superheat > target superheat degree+dead zone, degree of superheat deviation=suction superheat-target superheat degree-is dead
Area；
When suction superheat < target superheat degree-dead zone, degree of superheat deviation=suction superheat-target superheat degree+dead
Area.
When suction superheat be greater than or equal to target superheat degree-dead zone, and be less than or equal to target superheat degree+dead zone, mistake
Temperature deviation=0
After the adjusting step number for calculating the electric expansion valve in regulating cycle based on above-mentioned calculation method, based in regulating cycle
Electric expansion valve step number Ev (t)=EV (t-1)+u (t) determine electric expansion valve step number in this regulating cycle namely previous
The electric expansion valve step number in period is controlled plus the electric expansion valve step number that electronic expansion valve regulation step number is in this period
