Brief description of the drawings
Fig. 1 is the flow chart of the one embodiment based on control method for frequency conversion air conditioner of the present invention.
Specific embodiment
Technical scheme is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is referred to, the figure show the flow chart of the one embodiment based on control method for frequency conversion air conditioner of the present invention.
As shown in figure 1, the embodiment realizes control method for frequency conversion air conditioner, specifically realizes wall-mounted convertible frequency air-conditioner system
The detailed process of cooling control method is as follows：
Step 101：Air-conditioning is started shooting, and controls compressor operating.
After air-conditioning start, by operational mode set according to user or acquiescence and operational factor, according to predetermined control
Programme-control compressor operating.
Step 102：Judge whether air-conditioner enters room temperature PID control.If so, performing step 104；If it is not, performing step
103。
During airconditioning control, basis is controlled whether that entering room temperature PID control performs different controls to compressor
Whether system, specifically, into room temperature PID control the necessary bar that is compensated to indoor temperature is determined whether to compressor
Part.
Wherein, room temperature PID control refer to according to the temperature difference of current indoor temperature and indoor target temperature as control targe,
Perform a kind of control process of PID control.And, after air-conditioning start, room temperature PID control is not immediately entered, usually exist
The temperature difference between current indoor temperature and indoor target temperature is small to PID control is just entered after certain value, therefore, it can according to working as
Whether the temperature difference between preceding indoor temperature and indoor target temperature is small to judge whether air-conditioner enters room temperature PID control to certain value
System.In addition to this it is possible to using in the prior art other can determine that air-conditioner whether into room temperature PID control method enter
Row judges.
Step 103：If step 102 judges that air-conditioner is also introduced into room temperature PID control, according to conventional control methods control
Compressor.
If that is, air-conditioning is also introduced into room temperature PID control, not performing the treatment of indoor temperature compensation, but according to
Conventional control methods control compressor.Wherein, conventional control methods refer to the control method of existing transducer air conditioning.For example, existing
The control method for having air-conditioner is：When the temperature difference between temperature and indoor target temperature is more than the setting temperature difference indoors, control compression
Machine high frequency runs, until indoor temperature is not more than the setting temperature difference with the temperature difference of indoor target temperature.So, in compressor operating
Between also not up to setting run time when, if in conventional control methods compressor want high frequency run, keep high frequency run shape
State so that indoor temperature can quickly approach indoor target temperature, rapidly provides the user a more suitable indoor ring
Border.
During according to conventional control methods control compressor operating, still constantly perform and judge whether air-conditioning enters room temperature
The process of PID control.
Step 104：If step 102 judges that air-conditioning, into room temperature PID control, will be compensated to indoor temperature, then,
The compressor frequency that room temperature PID is controlled is calculated using the indoor temperature after compensation.
Specifically, when judging that air-conditioning is controlled into room temperature PID, the current indoor of indoor temperature transmitter detection is obtained
Temperature, as the first indoor temperature, calculates the difference of the first indoor temperature and setting compensation temperature, as the second indoor temperature.
Wherein, setting compensation temperature is the temperature value that prestore, can call at any time, be also before air-conditioning dispatches from the factory,
By air-conditioning research staff the number for obtaining and being written in accumulator for air conditioner is tested by special experiment condition and special test means
Value.When setting run time is reached between when the compressor is operating, the condition that control is compensated to indoor temperature is met, then obtained
The current indoor temperature detected by indoor temperature transmitter is taken, using the current indoor temperature as the first indoor temperature.Then,
Setting compensation temperature is obtained, the difference of the first indoor temperature and setting compensation temperature is calculated, using the difference as the second Indoor Temperature
Degree.Then, step 105 is performed.
Step 105：The temperature difference of the second indoor temperature and indoor target temperature is calculated, the indoor temperature difference is obtained, according to Indoor Temperature
Difference carries out room temperature PID computing, obtains compressor first object frequency.
Wherein, according to the indoor temperature difference carry out room temperature PID computing, acquisition compressor is controlled target frequency it is specific
Method can be realized using prior art.But, unlike the prior art, calculate the indoor temperature of the indoor temperature difference not
The temperature of indoor temperature transmitter detection, but the temperature to detecting has carried out the second indoor temperature obtained after temperature-compensating.
Step 106：Judge whether the second indoor temperature that step 104 is obtained is less than comfort temperature.If so, performing step
108 and the dual PID control of subsequent step；Otherwise, the room temperature PID control of step 107 is performed.
The step 106 can simultaneously be carried out with step 104 and step 105, be divided into herein sequentially describe only be for
Clearly state the control process of the embodiment.After step 104 obtains the second indoor temperature, by the second Indoor Temperature
Spend and made comparisons with the comfort temperature of setting, and judge the second indoor temperature whether less than comfort temperature.Wherein, comfort temperature can be with
It is a default setting temperature of air-conditioning when dispatching from the factory, or a design temperature that is voluntarily selected by user and setting.Such as
Fruit is that, by user's sets itself, air-conditioning can provide a reference temperature value, for reference.For example, it is proposed that by the comfortable temperature
Degree is set as 27 DEG C.
Step 107：If the second indoor temperature is not less than comfort temperature, room temperature PID control is performed, according to first object frequently
Rate controls compressor.
If step 106 judges that the second indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, then perform
Room temperature PID is controlled, according to first object FREQUENCY CONTROL compressor so that indoor temperature fast cooling to indoor target temperature.
Step 108：If the second indoor temperature is less than comfort temperature, dual PID control is performed.
If step 106 judges that indoor temperature is less than comfort temperature, to avoid the too fast decline of temperature from causing body-sensing uncomfortable,
Dual PID control is performed, to adjust compressor operating frequency in time so that evaporator coil temperature can be stabilized to coil pipe mesh
Mark temperature, to adjust air conditioning exhausting temperature, reaches cool without cold comfortable air-out effect.The process ginseng of specific dual PID control
See below the description of step 109 and step 110.
Step 109：The coil temperature of evaporator is detected, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtain the second target
Frequency.
The detection of the coil temperature of evaporator can be detected by setting temperature sensor on evaporator coil.Detection
Go out after coil temperature, the temperature difference between coil temperature and coil pipe target temperature is calculated, using the temperature difference as the coil pipe temperature difference.Its
In, coil pipe target temperature determines in real time according to indoor real-time humidity, and coil pipe target temperature is small when meeting real-time high humidity.
Then, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtains the target frequency being controlled to compressor, and by the target frequently
Rate is defined as the second target frequency.The method that disk temperature PID arithmetic obtains the target frequency being controlled to compressor may be referred to
Room temperature PID computing of the prior art and the method that obtains compressor target frequency.Wherein, the original frequency of disk temperature PID arithmetic
It can be an original frequency for setting.Preferably, the original frequency of disk temperature PID arithmetic is step:106 judge that indoor temperature is small
The current operation frequency of compressor when comfort temperature, execution dual PID control.And, the current operation frequency is at least
Compressor operating is for a period of time（Such as 3min）A running frequency afterwards.
Step 110：In the second target frequency that the first object frequency calculated according to step 105 is calculated with step 109
Smaller value controls compressor.
When temperature is less than comfort temperature indoors, disk temperature PID arithmetic is performed according to coil temperature and coil pipe target temperature, and
Smaller value control in the second target frequency that the first object frequency and disk temperature PID arithmetic exported according to room temperature PID computing are exported
Compressor operating processed, coil temperature is adjusted while refrigeration cool-down so that coil temperature can be approached to coil pipe target temperature.
When air-conditioner runs refrigeration mode, the temperature that indoor temperature transmitter is detected is higher than user's main activities space
Temperature.If the temperature for still being detected according to indoor temperature transmitter participates in PID arithmetic as indoor temperature, during PID arithmetic
The indoor temperature difference it is bigger than normal, the compressor target frequency for calculating is higher, and control compressor runs according to higher target frequency, leads
Cause air-conditioner energy consumption bigger than normal.And the method for using the embodiment, the indoor temperature of detection is first subtracted into a compensation temperature, obtain
More realistically reflect user and mainly live less than the second indoor temperature of the current indoor temperature of detection, and second indoor temperature
The temperature in dynamic space.When PID arithmetic is participated in using second indoor temperature less than normal, less compressor target is obtained in that
Frequency, using the less target frequency control compressor operating, reduces energy consumption.It is additionally, since second indoor temperature more
The temperature in user's main activities space is truly reflected, thus, can also cause that the indoor temperature after regulation is closer to room
Interior design temperature, without the problem of overshoot, reduces air-conditioner energy consumption while temperature adjustment comfortableness is met.Together
When, by setting comfort temperature, the second indoor temperature is made comparisons with comfort temperature, when temperature is higher indoors, using room temperature
PID control compressor operating so that indoor temperature fast cooling simultaneously approaches indoor target temperature.Temperature is less than comfortable temperature indoors
When spending, using room temperature PID control and the dual PID control of disk temperature PID control：When disk temperature PID control is had just enter into, disk temperature PID
Control plays a major role, and preferentially rises to coil temperature while cooling and approaches coil pipe target temperature；And in coil temperature
During close to coil pipe target temperature, room temperature PID plays a major role so that the stable target temperature indoors of indoor temperature, it is to avoid because of room
Warm overshoot and cause air-conditioning shut down phenomenon generation.So that during whole refrigeration control, room is approached indoor temperature is caused
Cause that coil temperature approaches coil pipe target temperature on the basis of interior target temperature, both met room temperature regulation, air conditioning exhausting is realized again
Comfortableness, reach cool without cold refrigeration.And, coil pipe target temperature during disk temperature PID control according to
Indoor real-time humidity determines that coil pipe target temperature is small during real-time high humidity so that control coil pipe to approach during high humidity indoors
And relatively low target temperature is maintained, to condense the moisture in more air, reach reduction air humidity, further improve room
The purpose of interior air pleasant.

If real-time humidity belongs to comfort humidity scope, coil pipe target temperature will be recommended to be defined as performing disk temperature PID arithmetic
Actual coil pipe target temperature.
If real-time humidity is not belonging to comfort humidity scope and humidity, will be low more than the higher limit of comfort humidity scope in real time
In the actual coil pipe target temperature for recommending the temperature of coil pipe target temperature to be defined as performing disk temperature PID arithmetic.
Wherein, it is a temperature that is known, prestoring to recommend coil pipe target temperature, general, is research staff's warp
One of heat exchange air that a large amount of theoretical researches and experiment test are obtained, that proper temperature can be sent out under comfort humidity
Coil temperature.Certainly, the recommendation coil pipe target temperature can also be changed by mandate, for example, by personnel after sale in user
Modified by special instruction in family.
Adopt when coil pipe target temperature is determined according to real-time humidity with the aforedescribed process, if humidity belongs to comfortable wet in real time
Degree scope, then using recommendation coil pipe target temperature as actual coil pipe target temperature, it is ensured that obtained when disk temperature PID control is performed
Suitable air conditioning exhausting.And if humidity is not belonging to comfort humidity scope in real time, and humidity is more than comfort humidity scope in real time
Higher limit, for example, more than 60%, shows that now indoor humidity is larger.In this case, coil pipe target temperature is reduced, specifically
Will be less than the actual coil pipe target temperature for recommending the temperature of coil pipe target temperature to be defined as performing disk temperature PID arithmetic.If in real time
Humidity is not belonging to comfort humidity scope and humidity, less than the lower limit of comfort humidity scope, preferably will also recommend coil pipe mesh in real time
Temperature is marked as actual coil pipe target temperature, to ensure the air conditioning exhausting of acquisition proper temperature.
It should be noted that during dual PID control is performed, still constantly comparing the second indoor temperature and relaxing
The size of thermophilic degree.Once indoor temperature is not less than comfort temperature, then dual PID control process is exited, be transferred to room temperature PID control
Process processed.
And, in whole control process, not compressor runs the compensation for being carried out indoor temperature at the beginning, but first
Compressor is kept to be run according to conventional control strategy, it is ensured that indoor temperature can be according to conventional control mode, be rapidly close to
Indoor target temperature, does not interfere with the speed of indoor temperature comfort conditioning.
Used as preferred embodiment, temperature is not less than comfort temperature and the difference of indoor temperature and comfort temperature indoors

Difference, for example, being set as 1 DEG C, it can be ensured that coil temperature is not less than coil pipe target temperature, it is ensured that go out cool to be relaxed without cold
Adaptive.
And, in the air conditioner refrigerating operation control process of the embodiment, if the non-wind speed setting of user, controls air-conditioning
Blower fan runs according to highest wind velocity, because under same refrigerating capacity, the leaving air temp of high wind speed is higher than the air-out of low wind speed
Temperature, further ensures that leaving air temp will not be too low.And if detect user setting wind speed, control blower fan according to setting
Wind speed runs.
