Specific 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 of method that the embodiment is controlled to air-conditioner comprises the following steps：
Step 101：Receive airconditioning control instruction.
Step 102：Judge whether the control refrigeration that step 101 is received is refrigerated energy-saving comfortable cooling.If it has not, performing
Step 103；Otherwise, step 104 is performed.
User can be input into airconditioning control and instruct by convertible frequency air-conditioner control panel, it is also possible to by 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, realizes not only energy-conservation 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 has pressed, and judge be button corresponding to refrigerated energy-saving comfortable cooling by by
Under, representing that user input refrigerated energy-saving is comfortably instructed, then the refrigerated energy-saving for starting into step 104 is comfortably instructed.
Step 103：If step 102 judges that received airconditioning control instruction is not that refrigerated energy-saving is comfortably instructed,
According to original VFC Schema control convertible frequency air-conditioner.Then, step 101 is gone to, the instruction of reception airconditioning control is kept simultaneously
Judged.
Original VFC pattern refers to the control model that convertible frequency air-conditioner has before refrigerated energy-saving comfort mode is set up.
Original VFC pattern not only includes the process according to FREQUENCY CONTROL compressor operating, also including according to user's wind speed setting control
Indoor fan processed and outdoor fan run, aperture of electric expansion valve, etc. are controlled according to the degree of superheat.And, original frequency conversion control
The process being controlled to compressor frequency in molding formula preferably realized using Fig. 3 flows, refers to the follow-up description to Fig. 3.
Step 104：If step 102 judges that received airconditioning control instruction is that refrigerated energy-saving is comfortably instructed, 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 for a user not modifiable, because user is difficult to know the threshold value
Implication and function, if arbitrarily changed by user, can increase energy consumption, reduce refrigeration comfortableness on the contrary.The threshold value can be by after sale
Personnel or other professionals are operated by upgrading to air-conditioner controller etc. and carry out numerical value modification.And, setting interior ring
Border temperature threshold is that most people body-sensing is more comfortable, will not feel a too hot temperature value, for example, be 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, detect current indoor temperature, and with the indoor ring of setting
Border temperature threshold makees the comparing of size.
Step 105：Judge current indoor temperature whether less than setting indoor environment temperature threshold value.If so, performing step
106；Otherwise, step 103 is performed.
If current indoor temperature shows that indoor environment temperature is higher not less than setting indoor environment temperature threshold value, then hold
Row step 103, according to original VFC Schema control convertible frequency air-conditioner, to enable indoor temperature rapid decrease.And,
During according to original VFC Schema control convertible frequency air-conditioner, step 104 is gone to, persistently detect current indoor temperature, and
Made comparisons with setting indoor environment temperature threshold value.
Step 106：If current indoor environment temperature shows indoor environment temperature less than setting indoor environment temperature threshold value
It is low, may be close to design temperature.And, 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：Judge the compressor target frequency acquired in step 106 whether less than the first setting compressor frequency.
If so, performing 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 lower the temperature, 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.And, during according to original VFC Schema control convertible frequency air-conditioner, step 104 is gone to, continue
Detection current indoor temperature, and 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 for actually calculating is less than the first setting compressor frequency, control compressor carries out low
Frequency limit frequency, makes its compressor low-limit frequency be the first setting compressor frequency, rather than according to the compressor mesh for actually calculating
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 obtained by theoretical research and a large amount of comprehensive experiments by research staff
Value, is the reasonable frequency value that can take into account low energy consumption and refrigeration comfortableness.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 ran 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 compressor running 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 maintain the stabilization of indoor temperature so that fluctuations in indoor temperature is big, and temperature influences comfortableness after rising.And
Temperature is lowered the temperature 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 for actually calculating is less than the first setting compressor frequency,
Control compressor carries out low frequency limit frequency.Compressor runs under the first setting compressor frequency, can produce maintenance Indoor Temperature
Spend the refrigerating capacity of stabilization so that indoor temperature stabilization improves comfortableness in user's design temperature.It is additionally, since indoor temperature steady
Fixed, the cycle that compressor is operated in a high frequency again lengthens.Thus, from Energy Efficiency Ratio, the compressor consumption in whole process of refrigerastion
Electricity is small, so as to reduce the energy consumption of air conditioner refrigerating.
And, 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 stablize Indoor Temperature
Degree, improves 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 obtained by theoretical research and a large amount of comprehensive experiments by research staff
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, the control which condition is put into which condition is met, when certain condition is unsatisfactory for
Just exit corresponding control.
Fig. 2 is referred to, the figure show second flow chart of 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 of method that the embodiment is controlled to air-conditioner comprises the following steps：
Step 201：Receive airconditioning control instruction.
Step 202：Judge whether the control refrigeration that step 201 is received is refrigerated energy-saving comfortable cooling.If it has not, performing
Step 203；Otherwise, step 204 is performed.
Step 203：If step 202 judges that received airconditioning control instruction is not that refrigerated energy-saving is comfortably instructed,
According to original VFC Schema control convertible frequency air-conditioner.Then, step 201 is gone to, the instruction of reception airconditioning control is kept simultaneously
Judged.
Step 204：If step 202 judges that received airconditioning control instruction is that refrigerated energy-saving is comfortably instructed, 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 current indoor environment temperature whether less than setting indoor environment temperature threshold value.If so, performing step
Rapid 206；Otherwise, step 203 is performed.
Step 206：If current indoor environment temperature is obtained according to original frequency conversion less than setting indoor environment temperature threshold value
The compressor target frequency that control model is calculated.
Step 207：Judge the compressor target frequency acquired in step 206 whether less than the first setting compressor frequency.
If so, performing 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, performing 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 implement process, principle and purpose and Fig. 1 embodiments to step 207 and step 209
Correspondence step is similar to, and is no longer specifically described, and details refer to the description of Fig. 1.
By step 209, from unlike Fig. 1 embodiments, Fig. 2 embodiments increased 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.And, set with first
Determine compressor frequency similar, 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 obtained by theoretical research and a large amount of comprehensive experiments by research staff
The value for obtaining, is the reasonable frequency value that can take into account low energy consumption and refrigeration comfortableness.
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 then controls the electric expansion valve of convertible frequency air-conditioner less than the second setting compressor frequency
Aperture is setting aperture.
Wherein, setting aperture be convertible frequency air-conditioner dispatch from the factory be have been written into one in the memory of air-conditioner controller it is solid
Definite value, and the value is the value obtained by theoretical research and a large amount of comprehensive experiments by research staff.For example, being set first
Determine compressor frequency for 15Hz, second set compressor frequency as 20Hz when, set aperture as 100 steps.According to original frequency conversion
When the compressor target frequency that control model is calculated 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 the aperture of control electric expansion valve is fixed.And, it is 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 is the degree of superheat adjusts valve, refrigeration effect can not be more preferably realized by controlling valve opening at low frequency
Really.And it is fixed aperture that the embodiment controls electric expansion valve in compressor low-frequency operation, suitable refrigerating capacity is obtained in that
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, performing 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, controls the actual motion frequency of compressor to rise to the 3rd setting compressor frequency, and continuous service second sets
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.
Perform above-mentioned steps 211 to the purpose of step 213 be in order to compressor low frequency and continuous operating carry out protection control,
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 to have been written into a fixed value in the memory of air-conditioner controller, and should
Value is the value obtained by theoretical research and a large amount of comprehensive experiments by research staff.For example, the first setting time is
30min, the second setting time is 10s, and the 3rd sets compressor frequency as 30Hz.When compressor is with less than the second setting compressor
After the actual motion frequency of frequency 20Hz continuously runs 30min, the running frequency of compressor is forced to rise to 30Hz, and continue fortune
Row 10s.Then, then the 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, meets the control which condition is put into which condition, not
Corresponding control is just exited when meeting certain condition.
Either Fig. 1 embodiments or Fig. 2 embodiments, when the comfortable control process of refrigerated energy-saving is entered, with existing frequency conversion
Airconditioning control is similar, it is necessary to pre-set airconditioning control parameter, 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
, there is matching for an optimal control parameter and control performance in convertible frequency air-conditioner.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, optimal control parameter and control is understood for user
Benchmark processed.
But, to meet the individual demand of user, acquiescence airconditioning control parameter is not modifiable, and user can be with
The default control parameters that will be shown reset according to self-demand as reference data to control parameter.
Now, receive airconditioning control refrigeration for refrigerated energy-saving comfortable cooling and show acquiescence airconditioning control parameter it
Afterwards, if detecting the airconditioning control parameter for resetting within the setting setting time, according to the air-conditioning control for resetting
Parameter processed performs the comfortable control process of refrigerated energy-saving.And if being not detected by the air-conditioning for resetting within the setting setting time
Control parameter, then will perform the comfortable control process of refrigerated energy-saving according to airconditioning control parameter of submerging.
Fig. 3 is referred to, the figure show one particular flow sheet of original VFC pattern in Fig. 1 and Fig. 2.
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, performing step 304；If it is not,
Perform step 303.
Wherein, setting run time is the time value that prestore, can call at any time, be before air-conditioning dispatches from the factory, by
Air-conditioning research staff tests the numerical value for obtaining and being written in accumulator for air conditioner by special experiment condition and special test means.
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
Whether Cheng Zhong, will reach setting run time according to compressor operating time, perform different controls.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.
If that is, run time also not up to sets run time after compressor start, indoor temperature benefit is not performed
The treatment 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 indoor temperature is not more than the setting temperature difference with the temperature difference of indoor target temperature.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 according to conventional control methods control compressor operating, 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 that room temperature PID is controlled 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, calculates the difference of the first indoor temperature and setting compensation temperature, makees
It is 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 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, 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 306：Judge whether the second indoor temperature that step 304 is obtained is less than comfort temperature.If so, performing 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 simultaneously be carried out 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 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 307：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 306 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 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
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 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, 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 that step 306 judges 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 310：In the second target frequency that the first object frequency calculated according to step 305 is calculated with step 309
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.Additionally, 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.

First store, be a humidity range for reflecting that human feeling is more suitable, for example, comfort humidity scope is for relative humidity
40-60%。
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.

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
During more than the difference for setting, then dual PID control process is exited, 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, 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.
