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 of the wall-mounted transducer air conditioning control method one embodiment of the present invention
Cheng Tu.
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 refrigeration that judgment step 101 is received is refrigerated energy-saving comfortable cooling.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 refrigeration.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 button corresponding to refrigerated energy-saving comfortable cooling 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 or Fig. 4 flow, is referred to subsequently to Fig. 3
And Fig. 4 description.
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 that to be dispatched from the factory in convertible frequency air-conditioner be the memory that has been written into air-conditioner controller
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 that to be dispatched from the factory in convertible frequency air-conditioner be to have been written into air-conditioner controller
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 of wall-mounted second embodiment of transducer air conditioning control method of the present invention
Figure.In this embodiment, the compressor of convertible frequency air-conditioner is the compressor of changeable frequency, and in the refrigerating of convertible frequency air conditioner circulatory system
Throttle 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 convertible frequency air-conditioner comprises the following steps:
Step 201:Receive airconditioning control instruction.
Step 202:Whether the control refrigeration that judgment step 201 is received is refrigerated energy-saving comfortable cooling.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 that to be dispatched from the factory in convertible frequency air-conditioner be to have been written into airconditioning control
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 to be dispatched from the factory in convertible frequency air-conditioner be have been written into the memory of air-conditioner controller one 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
The frequency operation of the reason for 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 that to be dispatched from the factory in convertible frequency air-conditioner be a fixed value having been written into 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 refrigeration for refrigerated energy-saving comfortable cooling 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

Control parameter, then it will perform the comfortable control process of refrigerated energy-saving according to airconditioning control parameter is submerged.
Fig. 3 is referred to, the figure show a particular flow sheet of original VFC pattern in Fig. 1 and Fig. 2.First,
Briefly explain the technical thought of original VFC pattern:For wall-hanging air conditioner, installation site is of a relatively high in room,
Typically all it is arranged on apart from the position on 2 meters or so of ground.The indoor temperature transmitter for being used for detecting indoor temperature on air-conditioning is general
In air conditioner air inlet or evaporator, thus, the air themperature that indoor temperature transmitter is detected is apart from 2 meters of ground
The temperature for the air that left and right is highly located.And in room, user's main activities Spatial General 6 R is from ground to apart from ground 1.35
The area of space of rice or so.According to the theory of molecular motion, cold air moves downward.So, when air conditioner runs refrigeration mode, by
Sink in cold air, the temperature of upper air is also than the temperature drift of lower air.So as to which indoor temperature transmitter is detected
Temperature drift in the temperature in user's main activities space.The embodiment is based on the phenomenon, from indoor temperature this angle in itself
Set out, it is proposed that a kind of air conditioner control for taking into account the comfortableness of temperature adjustment and the low-power consumption energy saving of air conditioner in air conditioner chamber
Technical scheme processed, and applied in original VFC pattern.
Specifically, in original VFC pattern, the method flow of the one embodiment being controlled to air conditioner
Comprise the following steps:
Step 301: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 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 fuzzy 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, fuzzy 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,
Fuzzy control is performed, to adjust compressor operating frequency in time so that evaporator coil temperature can be stabilized to coil pipe target
Temperature, to adjust air conditioning exhausting temperature, reach cool without cold comfortable air-out effect.The process of specific fuzzy control is referring to following
Step 309 to step 312 description.
Step 309:Detect the coil temperature of evaporator.
The detection of the coil temperature of evaporator can be by setting temperature sensor to be detected on evaporator coil.
Step 310:Judge whether coil temperature is more than coil pipe target temperature.If so, perform step 312;Otherwise, step is performed
Rapid 311.
After step 309 detects coil temperature, coil temperature is made comparisons with the coil pipe target temperature set, and sentences
Whether disconnected coil temperature is more than coil pipe target temperature.Wherein, coil pipe target temperature can be that an acquiescence of air-conditioning when dispatching from the factory is set
Constant temperature degree, naturally it is also possible to be the design temperature voluntarily selected by user and set.If by user's sets itself, by
It is not very clearly, preferably to provide one with reference to temperature by air-conditioning for the concept of coil temperature and its performance indications of representative in user
Angle value, it is for reference selected.Such as, it is proposed that the coil pipe target temperature is set as 14 DEG C.
Step 311:If coil temperature is not more than coil pipe target temperature, compressor current operation frequency is reduced and obtains the
Two target frequencies, the smaller value in the second target frequency and first object frequency control compressor.
If step 310 judges that coil temperature is not more than coil pipe target temperature, show that coil temperature is relatively low, easily cause sky
It is relatively low and send out cold wind to recall air temperature.To solve the problem, compressor current operation frequency is reduced and obtains the second target
Frequency.Then, the smaller value in the second target frequency and first object frequency controls compressor operating.
Compressor current operation frequency is reduced to the second target frequency, it is therefore an objective to enable coil temperature to coil pipe mesh
Mark temperature approaches.Simultaneously, it is contemplated that the stability of air-conditioning system operation so that indoor temperature approaches indoor target temperature, also needs
Take into account control of the room temperature PID to indoor temperature.Thus, the first object that the second target frequency and room temperature PID are calculated
Frequency is made comparisons, and selects smaller value control compressor operating therein.
Step 312:If coil temperature is more than coil pipe target temperature, according to first object FREQUENCY CONTROL compressor.
If step 310 judges that coil temperature is more than coil pipe target temperature, air conditioning exhausting temperature will not be relatively low, thus, will
The adjustment of room temperature is as main target, the first object FREQUENCY CONTROL compressor operating being calculated according to room temperature PID.
As preferred embodiment, in this embodiment, after the fuzzy control of step 108 is entered, in advance
Highest frequency of the highest frequency as comfortable cooling is set, either according to first object frequency according further to the second target
FREQUENCY CONTROL compressor, ensure that the frequency of compressor is no more than the highest frequency of setting.If that is, first object frequency
Rate or the second target frequency are more than highest frequency, then control compressor operating according to highest frequency.
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 the room temperature PID after compensation so that indoor temperature fast cooling simultaneously approaches indoor objects temperature
Degree;And when temperature is less than comfort temperature indoors, using the fuzzy control based on evaporator coil temperature, select room temperature PID or
The FREQUENCY CONTROL compressor that person reduces, so that coil temperature approaches on the basis of causing indoor temperature to approach indoor target temperature
Coil pipe design temperature, both met that room temperature was adjusted, and realized the comfortableness of air conditioning exhausting again, and reached cool and imitated without cold refrigeration
Fruit.
It should be noted that during fuzzy control is performed, still constantly compare the second indoor temperature with it is comfortable
The size of temperature.Once indoor temperature is not less than comfort temperature, then fuzzy control process is exited, be transferred to room temperature PID and controlled
Journey.
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.
In the above-described embodiments, when perform the compensation control of indoor temperature, how many temperature benefits is performed to indoor temperature
Repay, be the key factor for concerning air conditioner control comfortableness and energy saving.That is, setting run time and setting compensation temperature
From being key factor therein.
As preferred embodiment, the setting run time prestored in air-conditioning, called at any time is and indoor objects
Temperature and the corresponding run time of outdoor temperature, and prestore, the setting compensation temperature called at any time is and interior
Target temperature and the corresponding compensation temperature of outdoor temperature.Setting fortune is determined based on indoor target temperature and outdoor temperature
Row time and setting compensation temperature, operation of air conditioner load can be based on and realized to function of temperature compensation control in compensation time and compensation journey
Reasonable Regulation And Control on degree, reach Thermal comfort regulation and the equilibrium of low energy consumption energy saving.
Moreover, prestored in air-conditioning be indoor target temperature scope, outdoor temperature scope and with indoor objects temperature
Spend scope and the corresponding multiple run times of outdoor temperature scope and multiple compensation temperatures.Temperature is performed during operation of air conditioner
During degree compensation control, set run time and setting compensation temperature is called by following processes respectively:
Setting run time passes through following method calls:By indoor temperature transmitter detection current indoor target temperature with
The indoor target temperature scope prestored is made comparisons, and judges the indoor target temperature scope belonging to current indoor target temperature;
The current outdoor temperature that outdoor temperature sensor detects is made comparisons with the outdoor temperature scope prestored, judges current outdoor
Outdoor temperature scope belonging to temperature;According to prestoring, corresponding with indoor target temperature scope and outdoor temperature scope
Multiple run times in search with current indoor target temperature belonging to indoor target temperature scope and current outdoor temperature institute
The run time that the outdoor temperature scope of category is corresponding is used as setting run time, and calls;
Setting compensation temperature passes through following method calls:By current indoor target temperature and the indoor objects temperature prestored
Degree scope is made comparisons, and judges the indoor target temperature scope belonging to current indoor target temperature;By current outdoor temperature and in advance
The outdoor temperature scope of storage is made comparisons, and judges the outdoor temperature scope belonging to current outdoor temperature;According to it is prestoring, with
Searched and current indoor target temperature institute in indoor target temperature scope and the corresponding multiple compensation temperatures of outdoor temperature scope
The corresponding compensation temperature of outdoor temperature scope belonging to the indoor target temperature scope and current outdoor temperature of category is as setting
Compensation temperature, and call.
Certainly, in actual control process, indoor target temperature scope belonging to current indoor target temperature and cup is worked as
Outdoor temperature scope belonging to outer temperature only needs to judge once, then goes to search according to result of determination and call corresponding setting
Run time and setting compensation temperature, without judging twice affiliated scope, foregoing description sets only for complete explanation calling
Determine the process of run time and setting compensation temperature.
It is above-mentioned to be determined in a manner of temperature range and call setting run time and setting compensation temperature, data processing amount
Small, control process is simple, be more beneficial for air conditioner carry out in time, efficiently control, improve Thermal comfort regulation speed,
Reduce operation energy consumption.
Original another particular flow sheet of VFC pattern shown in Figure 4, it is to be directed to Fuzzy Control specifically
One idiographic flow of system.In addition to fuzzy control process and Fig. 3 differences, the compensation of remaining indoor temperature, room temperature PID fortune
The processes such as calculation, room temperature PID control are identical with Fig. 3, are not specifically addressed herein.Below only with regard to the fuzzy control process of the embodiment
Work is described below in detail:
Step 42:Perform fuzzy control.
Step 421:Detect the coil temperature of evaporator.
The detection of the coil temperature of evaporator can be by setting temperature sensor to be detected on evaporator coil.
Step 422:Judge whether coil temperature is more than coil pipe target temperature.If so, go to step 427;Otherwise, step is performed
Rapid 423.
The step more specific description referring to Fig. 3 description.
Step 423:Judge whether coil temperature is not more than coil pipe target temperature first.If so, perform step 424;Otherwise,
Perform step 425.
If step 422 judges that coil temperature is not more than coil pipe target temperature, then determines whether little first after starting shooting
In, and different processing is performed according to judged result.
Step 424:If coil temperature is to be not more than coil pipe target temperature first after starting shooting, will freeze minimum frequency conduct
Second target frequency.Then, step 426 is performed.
Freeze the minimum frequency that minimum frequency is the setting in air conditioner refrigerating running.In general, in the minimum frequency of refrigeration
Rate is the parameter set before air-conditioning dispatches from the factory.
Step 425:If coil temperature be start after it is non-be not more than coil pipe target temperature first, compressor is currently run
Frequency reduces, and obtains the second target frequency between current operation frequency and refrigeration minimum frequency.
If non-after coil temperature start be not more than coil pipe target temperature first, the current operation frequency of compressor is read
Rate, a frequency values being then chosen to be the second target frequency between current operation frequency and refrigeration minimum frequency.So
Afterwards, step 426 is performed.
Step 426:It is smaller in the first object frequency drawn according to the second target frequency and according to room temperature PID computing
Value control compressor.
Wherein, the calculating of first object frequency is referring to the description of Fig. 1 embodiments, and the second target frequency refers to according to step
424 or step 425 determined by target frequency.Moreover, the refrigeration minimum frequency in step 424 is no more than first object frequency
A frequency values, thus, if be not more than coil pipe target temperature first after coil temperature start, control compressor to freeze most
Small frequency is run.
If coil temperature is not more than coil pipe target temperature first, to avoid the reduction of air conditioning exhausting temperature from causing air-out
For cold wind, the frequency of compressor is first defined to the minimum frequency that freezes so that coil temperature rises to coil pipe design temperature as early as possible.
If coil temperature is non-to be not more than coil pipe target temperature first, show to have performed fuzzy control, then coil temperature will not be too
Less than coil pipe target temperature, now, the second target frequency is unnecessary near minimum, but between current operation frequency and refrigeration most
Between small frequency, to take into account the speed of room temperature regulation.
Need also exist for explanation, during fuzzy control is performed, still constantly compare indoor temperature with comfortably
The size of temperature.Once indoor temperature is not less than comfort temperature, then fuzzy control process is exited, be transferred to room temperature PID and controlled
Journey.
Determination for the second target frequency in step 425, a variety of methods can be selected, it is preferred to use the side shown in Fig. 5
Method.
Refer to Fig. 5, the figure shows in Fig. 4 coil temperature it is non-first be not more than coil pipe design temperature after determine second
One particular flow sheet of target frequency.
It is as shown in figure 5, non-first no more than the process that the second target frequency is determined after coil pipe design temperature in coil temperature
It is as follows:
Step 4251:Obtain compressor current operation frequency.
Step 4252:Compressor current operation frequency is reduced to the adjustment frequency of setting, the frequency after reduction is as second
Target frequency.
The adjustment frequency set a frequency values pre-set before being dispatched from the factory as air-conditioning, or be user's sets itself
One frequency values, for example, being set as 5Hz.The frequency values are represented every time to current operation frequency as a frequency adjusting step
Reduction amplitude.Moreover, the embodiment to frequency reduction using every setting adjustment time reduction once by the way of, realize by
Step section, and the frequency after reduction is as the second target frequency.
Step 4253:Judge whether the difference of coil pipe design temperature and coil temperature is more than overshoot temperature value.If so, perform step
Rapid 4254;Otherwise, step 4255 is gone to.
After current operation frequency reduces adjustment frequency, first judge whether the difference of coil pipe design temperature and coil temperature is big
In overshoot temperature value.Wherein, overshoot temperature value is also the temperature value of a setting, for example, being set as 1 DEG C.
Step 4254:If the difference of coil pipe design temperature and coil temperature is more than overshoot temperature value, judges whether to reach and adjust
The whole time.If so, going to step 4251, the adjustment process of frequency reduction is continued executing with.Otherwise, step 4255 is performed.
Step 4255:Second target frequency keeps constant.
If step 4253 judges that the difference of coil pipe design temperature and coil temperature is more than overshoot temperature value, show coil temperature
Far below coil pipe design temperature, it is still necessary to further frequency reducing.Moreover, the as it was previously stated, tune that down conversion process process sets for interval
The whole time reduces once.Adjustment time is also a pre-set value, represents the interval time of frequency adjustment.For example, can
To be set as 2min.That is, after adjustment once, first using the frequency after adjusting as the second target frequency, in adjustment time
When not up to, keep the second target frequency constant.Pressure is controlled with the smaller value in this second target frequency and first object frequency
Contracting machine is run, until exiting fuzzy control and entering room temperature PID control or shutdown.After adjustment time arrival, then read pressure
Contracting machine current operation frequency, based on current operation frequency, continue to carry out frequency reducing according to adjustment frequency.
And if step 4253 judges the difference of coil pipe design temperature and coil temperature and is not more than overshoot temperature value, show coil pipe
Though temperature does not reach coil pipe target temperature also, and the difference of coil pipe target temperature is smaller, no more than overshoot temperature value, now, then
Frequency is no longer reduced, to avoid the occurrence of the overshoot of coil temperature, and influences room temperature governing speed.Thus, keep step 4252
Second target frequency is constant, and controls compressor operating with the smaller value in this second target frequency and first object frequency, directly
Room temperature PID control or shutdown are entered to fuzzy control is exited.
In the air conditioner refrigerating operation control process of the various embodiments described above, 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.
