Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to drawings and examples,
The present invention is described in further detail.
Fig. 1 is referred to, the figure show the main flow chart of wall-hanging air conditioner control method one embodiment of the present invention.
As shown in figure 1, the flow for the method that the embodiment is controlled to air conditioner comprises the following steps：
Step 101：Receive airconditioning control instruction.
Step 102：Whether the control instruction that judgment step 101 is received is that refrigerated energy-saving comfortably instructs.If it has not, perform
Step 103；Otherwise, step 104 is performed.
User can input airconditioning control by convertible frequency air-conditioner control panel and instruct, and can also pass through convertible frequency air-conditioner remote control
Input airconditioning control instruction, can also by convertible frequency air-conditioner control of intelligent terminal, be such as provided with convertible frequency air-conditioner control APP intelligence
Mobile phone input airconditioning control instruction.No matter which kind of command input device used, refrigerated energy-saving is provided with the input and is relaxed
The special specified button of suitable instruction.User presses the button, it is possible to triggers convertible frequency air-conditioner and comfortably runs mould into refrigerated energy-saving
Formula, realization had not only saved but also the comfortable refrigeration control of temperature adjustment.Thus, user is facilitated independently to choose whether to perform the comfortable mould of refrigerated energy-saving
Formula.If convertible frequency air-conditioner has received control button and pressed, and judge be refrigerated energy-saving comfortably the corresponding button of instruction by by
Under, represent that user have input refrigerated energy-saving and comfortably instruct, then the refrigerated energy-saving started into step 104 comfortably instructs.
Step 103：If step 102 judges that received airconditioning control instruction is not that refrigerated energy-saving comfortably instructs,
According to original VFC Schema control convertible frequency air-conditioner.Then, step 101 is gone to, keeps and receives airconditioning control instruction simultaneously
Judged.
Original VFC pattern refers to convertible frequency air-conditioner possessed control model before refrigerated energy-saving comfort mode is set up.
Original VFC pattern not only includes the process according to FREQUENCY CONTROL compressor operating, also includes according to user's wind speed setting control
Indoor fan and outdoor fan processed run, aperture of electric expansion valve, etc. are controlled according to the degree of superheat.Moreover, original frequency conversion control
The process being controlled in molding formula to compressor frequency is preferably realized using Fig. 3 flows, refers to the description subsequently to Fig. 3.
Step 104：If step 102 judges that received airconditioning control instruction is that refrigerated energy-saving comfortably instructs, enter
The comfortable control model of refrigerated energy-saving.First, current indoor temperature is detected, is made comparisons with setting indoor environment temperature threshold value.
Setting indoor environment temperature threshold value is had been written into the memory of air-conditioner controller when convertible frequency air-conditioner dispatches from the factory.One
As, the setting indoor environment temperature threshold value is not modifiable for a user, because user is difficult to know the threshold value
Implication and function, if arbitrarily changed by user, energy consumption can be increased on the contrary, reduce refrigeration comfortableness.The threshold value can be by after sale
Personnel or other professionals carry out numerical value modification by operations such as the upgradings to air-conditioner controller.Moreover, the setting interior ring
Border temperature threshold is that most people body-sensing is more comfortable, will not feel a too hot temperature value, such as is set as 28 DEG C.Currently
Indoor temperature refers to a real time temperature at convertible frequency air-conditioner local environment space current time, can be by being arranged on air-conditioning air intake
Temperature sensor detection at mouthful.Into the comfortable control model of refrigerated energy-saving, current indoor temperature is detected, and with setting indoor ring
Border temperature threshold makees the comparison of size.
Step 105：Judge whether current indoor temperature is less than setting indoor environment temperature threshold value.If so, perform step
106；Otherwise, step 103 is performed.
If current indoor temperature shows that indoor environment temperature is higher, then held not less than setting indoor environment temperature threshold value
Row step 103, according to original VFC Schema control convertible frequency air-conditioner, to enable indoor temperature rapid decrease.Moreover,
During according to original VFC Schema control convertible frequency air-conditioner, step 104 is gone to, persistently detects current indoor temperature, and
Made comparisons with setting indoor environment temperature threshold value.
Step 106：If current indoor environment temperature is less than setting indoor environment temperature threshold value, show indoor environment temperature
It is low, it may be close to design temperature.Moreover, when close to design temperature, compressor will low-frequency operation.Now, basis is obtained
The compressor target frequency that original VFC mode computation goes out.
Step 107：Whether the compressor target frequency acquired in judgment step 106 is less than the first setting compressor frequency.
If so, perform step 108；If it is not, showing that user's design temperature is relatively low, current indoor temperature remains above user's design temperature, needs
Further to cool, thus, step 103 is gone to, according to original VFC Schema control convertible frequency air-conditioner, to cause indoor temperature
Being capable of rapid decrease.Moreover, during according to original VFC Schema control convertible frequency air-conditioner, step 104 is gone to, is continued
Current indoor temperature is detected, and is made comparisons with setting indoor environment temperature threshold value.
Step 108：If the compressor target frequency acquired in step 106 is less than the first setting compressor frequency, control
Compressor is run with the first setting compressor frequency, meanwhile, control outdoor fan is run with setting speed.
When the compressor target frequency actually calculated is less than the first setting compressor frequency, control compressor carries out low
Frequency limit frequency, make its compressor low-limit frequency for the first setting compressor frequency, rather than according to the compressor mesh actually calculated
Mark frequency operation.
Wherein, the first setting compressor frequency is the memory that air-conditioner controller is had been written into when convertible frequency air-conditioner dispatches from the factory
An interior fixed frequency, and the frequency is one obtained by research staff by theoretical research and a large amount of comprehensive experiments
Value, it is the reasonable frequency value that can take into account low energy consumption and comfortableness of freezing.For example, this first sets compressor frequency as 15Hz.
When the compressor target frequency gone out according to original VFC mode computation is less than 15Hz, show that real-time indoor environment temperature connects
Nearly user's design temperature, without more refrigerating capacity.But if what control compressor was run according to the frequency less than 15Hz
Words, due to underfrequency, its refrigerating capacity is extremely weak, or even can not play any refrigeration.Now, although compressor is low frequency
Operation, still consumes certain electricity, and its refrigerating capacity is extremely weak, so as to cause the running of compressor to be now almost one
Pure power consumption and do not have the process of refrigeration, from the point of view of Energy Efficiency Ratio angle, power consumption is big.Moreover, due to compression mechanism
Cold energy power is extremely weak, it is impossible to maintains the stabilization of indoor temperature so that fluctuations in indoor temperature is big, and temperature influences comfortableness after rising.And
Temperature is cooled after rising, it is necessary to control compressor to operate in a high frequency again, therefore, from the point of view of whole process of refrigerastion, power consumption
Greatly.
And in this embodiment, when the compressor target frequency actually calculated is less than the first setting compressor frequency,
Compressor is controlled to carry out low frequency limit frequency.Compressor is run under the first setting compressor frequency, can produce maintenance Indoor Temperature
Spend stable refrigerating capacity so that indoor temperature is stable in user's design temperature, raising comfortableness.It is steady to be additionally, since indoor temperature
Fixed, the cycle that compressor operates in a high frequency again lengthens.Thus, from Energy Efficiency Ratio, compressor consumes in whole process of refrigerastion
Electricity is small, so as to reduce the energy consumption of air conditioner refrigerating.
Moreover, in the limit frequency running, control outdoor fan is run with fixed setting speed, rather than according to original
There is VFC mode operation, the balance of whole refrigeration system can be kept when compressor limits frequency, further stablizes Indoor Temperature
Degree, improve the comfortableness of indoor temperature.Likewise, setting speed is to have been written into air-conditioner controller when convertible frequency air-conditioner dispatches from the factory
Memory in a fixed value, and the value is one obtained by research staff by theoretical research and a large amount of comprehensive experiments
Individual value.
During step 108 is performed, detection and the decision process of step 104 are still continuously carried out.
In a word, in refrigerating of convertible frequency air conditioner running, step 101, step 102, step 104, step 105 are constantly performed
And detection and the decision process of step 107, meet which condition is put into the control of which condition, when being unsatisfactory for some condition
Just exit corresponding control.
Fig. 2 is referred to, the figure show the flow chart of second embodiment of wall-hanging air conditioner control method of the present invention.
In the embodiment, the compressor of convertible frequency air-conditioner is the compressor of changeable frequency, and the throttling in the refrigerating of convertible frequency air conditioner circulatory system
Part is the controllable electric expansion valve of aperture.
As shown in Fig. 2 the flow for the method that the embodiment is controlled to air conditioner comprises the following steps：
Step 201：Receive airconditioning control instruction.
Step 202：Whether the control instruction that judgment step 201 is received is that refrigerated energy-saving comfortably instructs.If it has not, perform
Step 203；Otherwise, step 204 is performed.
Step 203：If step 202 judges that received airconditioning control instruction is not that refrigerated energy-saving comfortably instructs,
According to original VFC Schema control convertible frequency air-conditioner.Then, step 201 is gone to, keeps and receives airconditioning control instruction simultaneously
Judged.
Step 204：If step 202 judges that received airconditioning control instruction is that refrigerated energy-saving comfortably instructs, enter
The comfortable control model of refrigerated energy-saving.First, current indoor temperature is detected, is made comparisons with setting indoor environment temperature threshold value.
Step 205：Judge whether current indoor environment temperature is less than setting indoor environment temperature threshold value.If so, perform step
Rapid 206；Otherwise, step 203 is performed.
Step 206：If current indoor environment temperature is less than setting indoor environment temperature threshold value, obtain according to original frequency conversion
The compressor target frequency that control model calculates.
Step 207：Whether the compressor target frequency acquired in judgment step 206 is less than the first setting compressor frequency.
If so, perform step 209；Otherwise, step 208 is performed.
Step 208：If step 206 judges compressor target frequency not less than the first setting compressor frequency, then judges
Whether compressor target frequency is less than the second setting compressor frequency.If so, perform step 210；Otherwise, step 203 is gone to, still
Continuously carry out detection and the decision process of step 204.
Step 209：If the compressor target frequency acquired in step 206 is less than the first setting compressor frequency, control
Compressor is run with the first setting compressor frequency, meanwhile, control outdoor fan is run with setting speed.Then, step is performed
210。
Above-mentioned steps 201 are to specific implementation process, principle and the purpose of step 207 and step 209 and Fig. 1 embodiments
Corresponding step is similar, is no longer specifically described, details refer to Fig. 1 description.
By step 209, unlike Fig. 1 embodiments, Fig. 2 embodiments add step 208 by compressor target
The process that frequency is made comparisons with the second setting compressor frequency.Wherein, the second setting compressor frequency is than the first setting compressor
Frequency is big, for example, first sets compressor frequency as 15Hz, then second sets compressor frequency as 20Hz.Moreover, set with first
It is similar to determine compressor frequency, the second setting compressor frequency is also to have been written into airconditioning control when convertible frequency air-conditioner dispatches from the factory
A fixed frequency in the memory of device, and the frequency is to be obtained by research staff by theoretical research and a large amount of comprehensive experiments
The value obtained, it is the reasonable frequency value that can take into account low energy consumption and comfortableness of freezing.
Step 210：The step is transferred by step 208 and step 209, as long as that is, step 206 is according to original VFC
The compressor target frequency that mode computation goes out is less than the second setting compressor frequency, then controls the electric expansion valve of convertible frequency air-conditioner
Aperture is setting aperture.
Wherein, setting aperture is that one had been written into when convertible frequency air-conditioner dispatches from the factory in the memory of air-conditioner controller is solid
Definite value, and the value is the value obtained by research staff by theoretical research and a large amount of comprehensive experiments.For example, set first
It is 15Hz, second when setting compressor frequency as 20Hz to determine compressor frequency, sets aperture as 100 steps.According to original frequency conversion
When the compressor target frequency that control model calculates is less than the second setting compressor frequency, not according still further to original VFC mould
Formula is controlled to the aperture of electric expansion valve, but controls the aperture of electric expansion valve to fix.It is moreover, small in compressor frequency
When the second setting compressor frequency, the setting aperture is smaller than the aperture calculated according to original VFC pattern,
Because original control mode, which is the degree of superheat, adjusts valve, refrigeration effect more preferably can not be realized by controlling valve opening at low frequency
Fruit.And it is fixed aperture that the embodiment, which controls electric expansion valve in compressor low-frequency operation, suitable refrigerating capacity can be obtained
And cause air conditioning exhausting proper temperature.
Step 211：Judge whether compressor is reached with the actual motion frequency operation less than the second setting compressor frequency
First setting time.If so, perform step 212；Otherwise, timing is continued, until reaching the first setting time.
Step 212：If compressor is run to up to first with the actual motion frequency less than the second setting compressor frequency
Setting time, the actual motion frequency of compressor is controlled to rise to the 3rd setting compressor frequency, and continuous service second is set
Time.
Step 213：When compressor is run to up to the second setting time according to the 3rd setting compressor frequency, then return to
Original frequency operation before rising.
The purpose for performing above-mentioned steps 211 to step 213 is to carry out protection control to be operated to compressor low frequency and continuous,
Avoid compressor long-time low-frequency operation and damage compressor.Wherein, the first setting time, the second setting time and the 3rd setting
Compressor frequency is a fixed value being had been written into when convertible frequency air-conditioner dispatches from the factory in the memory of air-conditioner controller, and should
Value is the value obtained by research staff by theoretical research and a large amount of comprehensive experiments.For example, the first setting time is
30min, the second setting time are 10s, and the 3rd sets compressor frequency as 30Hz.When compressor is with less than the second setting compressor
After frequency 20Hz actual motion frequency continuously runs 30min, the running frequency of compressor is forced to rise to 30Hz, and continue to transport
Row 10s.Then, then original frequency to rising is recovered.
Perform above-mentioned compressor limit frequency and low-frequency operation protect during, still continuously carry out step 204 detection and
Decision process.
Certainly, in refrigerating of convertible frequency air conditioner running, step 201, step 202, step 204, step still can constantly be performed
Rapid 205, detection and the decision process of step 207 and step 208, meet which condition is put into the control of which condition, not
Meet just to exit corresponding control during some condition.
Either Fig. 1 embodiments or Fig. 2 embodiments, in control process comfortable into refrigerated energy-saving, with existing frequency conversion
Airconditioning control is similar, it is necessary to airconditioning control parameter be pre-set, such as user's design temperature, wind speed setting, air supply direction
Deng the comfortable control process of refrigerated energy-saving will be according to these airconditioning control Parameters on Compressive machine, indoor fan, outdoor fan, wind-guidings
Plate etc. is controlled, and meets user's request.Refrigerated energy-saving is comfortably controlled as an optimal control process, for a specific
Convertible frequency air-conditioner, the matching of optimal control parameter and a control performance be present.In order to provide Optimal Control performance, go out in air-conditioning
Before factory, the optimization control parameter for realizing optimum control performance of this air-conditioning, the optimization control parameter are prefixed in its storage
Airconditioning control parameter by default, in user using air-conditioning and when have selected the comfortable control model of refrigerated energy-saving, in airconditioning control
Acquiescence airconditioning control parameter is shown on panel or air cnoditioner remote controller display screen, understands optimal control parameter and control for user
Benchmark processed.
But to meet the individual demand of user, acquiescence airconditioning control parameter is not modifiable, and user can be with
Using the default control parameters of display as reference data, control parameter is reset according to self-demand.
Now, receive airconditioning control instruction comfortably instructed for refrigerated energy-saving and show acquiescence airconditioning control parameter it
Afterwards, if setting the airconditioning control parameter for detecting and resetting in the time in setting, according to the air-conditioning control reset
Parameter processed performs the comfortable control process of refrigerated energy-saving.And if setting the air-conditioning for being not detected by and resetting in the time in setting
Control parameter, then it will perform the comfortable control process of refrigerated energy-saving according to acquiescence airconditioning control parameter.
Fig. 3 is referred to, the figure show original one particular flow sheet of VFC pattern in Fig. 1 and Fig. 2.
First, the technical thought of original VFC pattern is briefly explained：For wall-hanging air conditioner, installed in room

Degree sensor is normally on air conditioner air inlet or evaporator, thus, the air themperature that indoor temperature transmitter is detected
It is the temperature of the air at the height of 2 meters or so of ground.And in room, user's main activities Spatial General 6 R be from ground to
Apart from 1.35 meters or so of the area of space in ground.According to the theory of molecular motion, cold air moves downward.So, run in air conditioner
During refrigeration mode, because cold air sinks, the temperature of upper air is also than the temperature drift of lower air.So as to Indoor Temperature
The temperature drift that degree sensor is detected is in the temperature in user's main activities space.The embodiment is based on the phenomenon, from Indoor Temperature
Degree in itself set out by this angle, it is proposed that a kind of to take into account the low-power consumption section of the comfortableness of temperature adjustment and air conditioner in air conditioner chamber

Step 302：Judge whether compressor operating time reaches setting run time.If so, perform step 304；If it is not,
Perform step 303.
Wherein, it is the time value that prestores, can call at any time to set run time, be before air-conditioning dispatches from the factory, by
Air-conditioning research staff is obtained by special experiment condition and the experiment of special test means and is written to the numerical value in accumulator for air conditioner.
Timer is provided with air-conditioning, timing can be carried out to the run time of compressor.In air-conditioning start, compressor
When bringing into operation, timer starts timing, when timing reaches setting run time, output time signal.In airconditioning control mistake
Cheng Zhong, whether setting run time will be reached according to compressor operating time, and perform different control.Specifically, compressor
Whether run time reaches the necessary condition that setting run time is determined whether to compensate indoor temperature.
Step 303：If step 302 judges that compressor operating time also not up to sets run time, according to conventional control
Method processed controls compressor.
That is, if run time also not up to sets run time after compressor start, indoor temperature benefit is not performed
The processing repaid, but control compressor according to conventional control methods.Wherein, conventional control methods refer to existing transducer air conditioning
Control method.For example, the control method of existing air conditioner is：The temperature difference between temperature and indoor target temperature is more than setting indoors
During the temperature difference, control compressor high frequency operation, until the temperature difference of indoor temperature and indoor target temperature is no more than the setting temperature difference.That
, in compressor operating time also not up to setting run time, if compressor wants high frequency to run in conventional control methods,
Then keep high frequency running status so that indoor temperature can quickly approach indoor target temperature, rapidly provide the user one
More suitable indoor environment.
During controlling compressor operating according to conventional control methods, still constantly perform whether judge compressor operating time
Reach the process of setting run time.
Step 304：If step 302 judges that compressor operating time reaches setting run time, indoor temperature will be entered
Row compensation, then, the compressor frequency of room temperature PID control is calculated using the indoor temperature after compensation.
Specifically, after the run time after compressor start reaches setting run time, indoor temperature sensing is obtained
The current indoor temperature of device detection, as the first indoor temperature, the difference of the first indoor temperature and setting compensation temperature is calculated, is made
For the second indoor temperature.
Wherein, setting compensation temperature is the temperature value that prestores, can call at any time, and air-conditioning dispatch from the factory before,
Obtained by air-conditioning research staff by special experiment condition and the experiment of special test means and be written to the number in accumulator for air conditioner
Value.When reaching setting run time between when the compressor is operating, the condition that control is compensated to indoor temperature is met, then is 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 305：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, room temperature PID computing carried out according to the indoor temperature difference, obtain the specific of the target frequency that is controlled to compressor
Method can be realized using prior art.But unlike the prior art, the indoor temperature for calculating the indoor temperature difference is not
The temperature of indoor temperature transmitter detection, but the second indoor temperature obtained after temperature-compensating has been carried out to the temperature of detection.
Step 306：Whether the second indoor temperature that judgment step 304 is obtained is less than comfort temperature.If so, perform step
308 and the dual PID control of subsequent step；Otherwise, the room temperature PID control of step 307 is performed.
The step 306 can be carried out simultaneously with step 304 and step 305, be divided into herein sequentially describe only be for
Clearly state the control process of the embodiment.After step 304 obtains the second indoor temperature, by the second Indoor Temperature
Spend and made comparisons with the comfort temperature set, and judge whether the second indoor temperature is 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 the design temperature voluntarily selected by user and set.Such as
Fruit is by user's sets itself, and air-conditioning can provide a reference temperature value, for reference.Such as, it is proposed that by the comfortable temperature
Degree is set as 27 DEG C.
Step 307：If the second indoor temperature is not less than comfort temperature, room temperature PID control is performed, according to first object frequency
Rate controls compressor.
If step 306 judges that the second indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, then performs
Room temperature PID controls, according to first object FREQUENCY CONTROL compressor so that indoor temperature fast cooling to indoor target temperature.
Step 308：If the second indoor temperature is less than comfort temperature, dual PID control is performed.
If step 306 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
Temperature is marked, 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 309 and step 310.
Step 309：The coil temperature of evaporator is detected, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtains the second target
Frequency.
The detection of the coil temperature of evaporator can be by setting temperature sensor to be detected on evaporator coil.Detection
Go out after coil temperature, the temperature difference between coil temperature and the coil pipe target temperature of setting is calculated, using the temperature difference as coil pipe temperature
Difference.Wherein, coil pipe target temperature can be a default setting temperature of convertible frequency air-conditioner when dispatching from the factory, naturally it is also possible to be by user
The design temperature voluntarily selected and set.If by user's sets itself, because user is for the concept of coil temperature
It is for reference selected and its performance indications represented are not very clearly, preferably to provide a reference temperature value by convertible frequency air-conditioner.
Such as, it is proposed that the coil pipe target temperature is set as 14 DEG C.Then, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtained to pressure
The target frequency that contracting machine is controlled, and the target frequency is defined as the second target frequency.Disk temperature PID arithmetic is obtained to compression
The method for the target frequency that machine is controlled may be referred to room temperature PID computing of the prior art and obtain compressor target frequency
Method.Wherein, the original frequency of disk temperature PID arithmetic can be the original frequency of a setting.Preferably, disk temperature PID arithmetic
Original frequency for step 306 judge indoor temperature be less than comfort temperature, perform dual PID control when compressor current operation
Frequency.Moreover, the current operation frequency is at least in compressor operating for a period of time（Such as 3min）A running frequency afterwards.
Step 310：In the second target frequency calculated according to the first object frequency that step 305 calculates with step 309
Smaller value controls compressor.
When temperature is less than comfort temperature indoors, disk temperature PID is performed according to coil temperature and the coil pipe target temperature of setting
Computing, and according to room temperature PID computing export first object frequency and disk temperature PID arithmetic export the second target frequency in compared with
Small value control compressor operating, adjusts coil temperature so that coil temperature can be to coil pipe target temperature while refrigeration cool-down
Degree approaches.
As previously indicated, when air conditioner runs refrigeration mode, the temperature that indoor temperature transmitter is detected is higher than user
The temperature in main activities space.If participate in PID fortune as indoor temperature still according to the temperature of indoor temperature transmitter detection
Calculate, indoor temperature difference during PID arithmetic is bigger than normal, and the compressor target frequency calculated is higher, and control compressor is according to higher mesh
Frequency operation is marked, causes air conditioner energy consumption bigger than normal.And the method for using the embodiment, the indoor temperature of detection is first subtracted one
Compensation temperature, the second indoor temperature of the current indoor temperature less than detection is obtained, and second indoor temperature is more realistically anti-
The temperature in user's main activities space is reflected.When participating in PID arithmetic using second indoor temperature less than normal, can obtain compared with
Small compressor target frequency, compressor operating is controlled using the less target frequency, reduces energy consumption.It is additionally, since this
Second indoor temperature more realistically reflects the temperature in user's main activities space, thus, it can also cause the Indoor Temperature after regulation
Degree is closer to indoor design temperature, the problem of without overshoot, is reduced while temperature adjustment comfortableness is met
Air conditioner energy consumption.Meanwhile by setting comfort temperature, the second indoor temperature is made comparisons with comfort temperature, indoors temperature
When higher, compressor operating is controlled using room temperature PID so that indoor temperature fast cooling simultaneously approaches indoor target temperature.In room
When interior temperature is less than comfort temperature, using room temperature PID control and the dual PID control of disk temperature PID control：Having just enter into disk temperature
During PID control, disk temperature PID control plays a major role, and preferentially rises to coil temperature while cooling and approaches coil pipe target
Temperature；And when coil temperature is close to coil pipe target temperature, room temperature PID plays a major role so that indoor temperature is stable indoors
Target temperature, avoid the generation for causing air-conditioning to shut down phenomenon because of room temperature overshoot.So as to, during whole refrigeration control,
So that indoor temperature is approached on the basis of indoor target temperature so that coil temperature approaches coil pipe design temperature, both meet that room temperature is adjusted
Section, realizes the comfortableness of air conditioning exhausting, reaches cool without cold refrigeration again.
It should be noted that during dual PID control is performed, still constantly compare the second indoor temperature with relaxing
The size of thermophilic degree.Once indoor temperature is not less than comfort temperature, then dual PID control process is exited, is transferred to room temperature PID control
Process processed.
Moreover, in whole control process, not compressor runs the compensation for being carried out indoor temperature at the beginning, but first
Keep compressor to be run according to conventional control strategy, ensure that indoor temperature can be according to conventional control mode, rapidly close
Indoor target temperature, the speed of indoor temperature comfort conditioning is not interfered with.
As preferred embodiment, temperature is not less than comfort temperature and the difference of indoor temperature and comfort temperature indoors
More than setting difference when, then exit dual PID control process, be transferred to room temperature PID control process.Set by reasonable selection
Difference, for example, being set as 1 DEG C, it can be ensured that coil temperature is not less than coil pipe target temperature, ensures and cool is relaxed without cold
Adaptive.
Moreover, in the air conditioner refrigerating operation control process of the embodiment, if the non-wind speed setting of user, controls air-conditioning
Blower fan is run 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 ensure that leaving air temp will not be too low.And if detect user setting wind speed, control blower fan according to setting
Wind speed is run.
In the above-described embodiments, when perform the compensation control of indoor temperature, how many temperature benefits is performed to indoor temperature
