Brief description of the drawings
Fig. 1 is the flow chart of the one embodiment based on transducer air conditioning control method of the present invention.
Specific embodiment
Technical scheme is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is referred to, the figure show the flow chart of the one embodiment based on control method for frequency conversion air conditioner of the present invention.
As shown in figure 1, the embodiment realizes transducer air conditioning control method, specifically realizes wall-mounted convertible frequency air-conditioner
The detailed process of refrigeration control method is as follows：
Step 101：Air-conditioning is started shooting, and controls compressor operating.
After air-conditioning start, by operational mode set according to user or acquiescence and operational factor, according to predetermined control
Programme-control compressor operating.
Step 102：Judge whether compressor operating time reaches setting run time.If so, performing step 104；If it is not,
Perform step 103.
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 103：If step 102 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 104：If step 102 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 105：The temperature difference of the second indoor temperature and indoor target temperature is calculated, the indoor temperature difference is obtained, according to Indoor Temperature
Difference carries out room temperature PID computing, obtains compressor first object frequency.
Wherein, according to the indoor temperature difference carry out room temperature PID computing, acquisition compressor is controlled target frequency it is specific
Method can be realized using prior art.But, unlike the prior art, calculate the indoor temperature of the indoor temperature difference not
The temperature of indoor temperature transmitter detection, but the temperature to detecting has carried out the second indoor temperature obtained after temperature-compensating.
Step 106：Judge whether the second indoor temperature that step 104 is obtained is less than comfort temperature.If so, performing step
108 and the dual PID control of subsequent step；Otherwise, the room temperature PID control of step 107 is performed.
The step 106 can simultaneously be carried out with step 104 and step 105, be divided into herein sequentially describe only be for
Clearly state the control process of the embodiment.After step 104 obtains the second indoor temperature, by the second Indoor Temperature
Spend and made comparisons with the comfort temperature of setting, and judge the second indoor temperature whether less than comfort temperature.Wherein, comfort temperature can be with
It is a default setting temperature of air-conditioning when dispatching from the factory, or a design temperature that is voluntarily selected by user and setting.Such as
Fruit is that, by user's sets itself, air-conditioning can provide a reference temperature value, for reference.For example, it is proposed that by the comfortable temperature
Degree is set as 27 DEG C.
Step 107：If the second indoor temperature is not less than comfort temperature, room temperature PID control is performed, according to first object frequently
Rate controls compressor.
If step 106 judges that the second indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, then perform
Room temperature PID is controlled, according to first object FREQUENCY CONTROL compressor so that indoor temperature fast cooling to indoor target temperature.
Step 108：If the second indoor temperature is less than comfort temperature, dual PID control is performed.
If step 106 judges that indoor temperature is less than comfort temperature, to avoid the too fast decline of temperature from causing body-sensing uncomfortable,
Dual PID control is performed, to adjust compressor operating frequency in time so that evaporator coil temperature can be stabilized to coil pipe mesh
Mark temperature, to adjust air conditioning exhausting temperature, reaches cool without cold comfortable air-out effect.The process ginseng of specific dual PID control
See below the description of step 109 and step 110.
Step 109：The coil temperature of evaporator is detected, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtain the second target
Frequency.
The detection of the coil temperature of evaporator can be detected by setting temperature sensor on evaporator coil.Detection
Go out after coil temperature, the temperature difference between coil temperature and coil pipe target temperature is calculated, using the temperature difference as the coil pipe temperature difference.Its
In, coil pipe target temperature determines in real time according to indoor real-time humidity, and coil pipe target temperature is small when meeting real-time high humidity.
Then, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, obtains the target frequency being controlled to compressor, and by the target frequently
Rate is defined as the second target frequency.The method that disk temperature PID arithmetic obtains the target frequency being controlled to compressor may be referred to
Room temperature PID computing of the prior art and the method that obtains compressor target frequency.Wherein, the original frequency of disk temperature PID arithmetic
It can be an original frequency for setting.Preferably, the original frequency of disk temperature PID arithmetic is step:106 judge that indoor temperature is small
The current operation frequency of compressor when comfort temperature, execution dual PID control.And, the current operation frequency is at least
Compressor operating is for a period of time（Such as 3min）A running frequency afterwards.
Step 110：In the second target frequency that the first object frequency calculated according to step 105 is calculated with step 109
Smaller value controls compressor.
When temperature is less than comfort temperature indoors, disk temperature PID arithmetic is performed according to coil temperature and coil pipe target temperature, and
Smaller value control in the second target frequency that the first object frequency and disk temperature PID arithmetic exported according to room temperature PID computing are exported
Compressor operating processed, coil temperature is adjusted while refrigeration cool-down so that coil temperature can be approached to coil pipe target temperature.
Step 111：During above-mentioned room temperature PID control or dual PID control, human body temperature is detected, and judge people
Whether temperature is abnormal.If abnormal, step 113 is performed, raise indoor target temperature as current indoor target temperature, and root
Refrigeration control is performed according to the indoor target temperature after rising；Otherwise, step 112 is performed, keeps current indoor target temperature constant,
Continue executing with refrigeration control.Then, step 106 is gone to.
And, if detecting human body temperature exception, air-conditioning alert and/or alarm signal can also be controlled.
For example, control air-conditioning sends warning message by built-in communication unit to user mobile phone, and mobile phone passes through after receiving warning message
The method of light, vibration or sound sends alarm signal.Or, control air-conditioning sends sound by the warning device that itself is set
The alarm signals such as sound, light.
In air conditioner refrigerating running, easily generating the problem that causes flu of catching a cold because of supercooling.If user is certainly
Whether I perceives consciousness and air conditioner operation level normally and in waking state, can in time perceive and be subcooled and control air-conditioning
Running status, to improve indoor environment temperature.But, if user self perceives consciousness and air conditioner operation horizontal abnormality, for example
Adult under baby or sleep state, it is impossible to perceive supercooling, under cold wind environment, then can be easier flu of suffering from cold.For
Solve the problem, the embodiment when air conditioner refrigerating runs, real-time detection human body temperature, and it is different to judge whether human body temperature occurs
Often.If there is exception, indoor target temperature will be automatically raised so that room temperature maintains state higher.
Specifically, the human body temperature temperature value including the predetermined patterns of human body first extremely is more than the first set temperature value.
For example, the first predetermined patterns are heads, head temperature value can reflect whether human body has a fever.Human body predetermined patterns and predetermined patterns
The detection of temperature, it is possible to use infrared detection means of the prior art are realized.For example, generated by infrared thermal imaging device
Thermal-induced imagery be analyzed, human head location is determined, so that it is determined that going out head temperature.Then, judge that head temperature is
It is no to be more than the first set temperature value.First set temperature value is also a numerical value set in advance, and whether reflection human body has a fever, example
Such as it is 37 DEG C.If head temperature is more than first set temperature value, show that human body occurs in that the exception of fever, will raise automatically
Indoor target temperature so that room maintains higher temperature.
Or, it is contemplated that individual body temperature difference and detection means precision problem, human body temperature can also include human body extremely
The temperature value of the first predetermined patterns is more than the second set temperature value and in rising trend.For example, the first predetermined patterns are still head
Whether portion, after determining head temperature and head temperature value more than the second set temperature value, then judge head temperature in rising
Trend.If head temperature is in rising trend, show that human body occurs in that the exception of fever.
Additionally, human body temperature can also include that the temperature value of the predetermined patterns of human body second is less than the 3rd design temperature extremely
Value.For example, the second predetermined patterns are trunks, reflect whether human body pedals quilt in a sleep state by trunk temperature value.Equally
, the temperature at the second predetermined patterns and the position is realized using infrared detection means of the prior art.3rd design temperature
Value can be set in advance, characterize the exposed actual temperature in the environment of the second predetermined patterns.When the temperature of the second predetermined patterns
Angle value be less than three set temperature values when, show that the human body position is not covered, but it is exposed in the environment, so as to judge human body
Such as quilt of overcover herein is raised.Now, it is also automatic to raise indoor target temperature so that room temperature is maintained at higher
State.
In view of individual body temperature difference, there is some difference for the normal body temperature of such as adult and infant, the 3rd setting
Temperature value includes multiple value corresponding with different user, for example, including corresponding to the value and the value corresponding to infant of adult.
When the temperature value of the second predetermined patterns is judged, first determine that human body is to be grown up or infant according to infrared detections, for
Different human body is made comparisons from the set temperature value of different numerical value.
Additionally, human body temperature can also include that the temperature value of the predetermined patterns of human body second is less than the 4th design temperature extremely
Value and reach the first difference with the difference of the 4th set temperature value.The 4th set temperature value herein is the default portion of mark second
Temperature value under the covered state in position, it is possible to use the self study in the state of human body is covered of the self-learning function of air-conditioning is obtained
Arrive.After the 4th set temperature value is obtained by self study, the temperature of the predetermined patterns of human body second is detected, by the temperature value and the
Four set temperature values are compared.If the temperature value of the second predetermined patterns is less than the 4th set temperature value, and have decreased to one
Tentering degree, the first difference with the difference of the 4th set temperature value has reached setting, then show that the second predetermined patterns are not covered.
Now, it is also automatic to raise indoor target temperature.
When air-conditioner runs refrigeration mode, the temperature that indoor temperature transmitter is detected is higher than user's main activities space
Temperature.If the temperature for still being detected according to indoor temperature transmitter participates in PID arithmetic as indoor temperature, during PID arithmetic
The indoor temperature difference it is bigger than normal, the compressor target frequency for calculating is higher, and control compressor runs according to higher target frequency, leads
Cause air-conditioner energy consumption bigger than normal.And the method for using the embodiment, the indoor temperature of detection is first subtracted into a compensation temperature, obtain
More realistically reflect user and mainly live less than the second indoor temperature of the current indoor temperature of detection, and second indoor temperature
The temperature in dynamic space.When PID arithmetic is participated in using second indoor temperature less than normal, less compressor target is obtained in that
Frequency, using the less target frequency control compressor operating, reduces energy consumption.It is additionally, since second indoor temperature more
The temperature in user's main activities space is truly reflected, thus, can also cause that the indoor temperature after regulation is closer to room
Interior design temperature, without the problem of overshoot, reduces air-conditioner energy consumption while temperature adjustment comfortableness is met.Together
When, by setting comfort temperature, the second indoor temperature is made comparisons with comfort temperature, when temperature is higher indoors, using room temperature
PID control compressor operating so that indoor temperature fast cooling simultaneously approaches indoor target temperature.Temperature is less than comfortable temperature indoors
When spending, using room temperature PID control and the dual PID control of disk temperature PID control：When disk temperature PID control is had just enter into, disk temperature PID
Control plays a major role, and preferentially rises to coil temperature while cooling and approaches coil pipe target temperature；And in coil temperature
During close to coil pipe target temperature, room temperature PID plays a major role so that the stable target temperature indoors of indoor temperature, it is to avoid because of room
Warm overshoot and cause air-conditioning shut down phenomenon generation.So that during whole refrigeration control, room is approached indoor temperature is caused
Cause that coil temperature approaches coil pipe target temperature on the basis of interior target temperature, both met room temperature regulation, air conditioning exhausting is realized again
Comfortableness, reach cool without cold refrigeration.And, during refrigeration control, human body temperature is detected, according to people
Whether temperature there is exception to decide whether to raise indoor target temperature, so that the control of air-conditioning more flexible, human nature
Change, further increase refrigeration comfortableness.Additionally, the coil pipe target temperature during disk temperature PID control is according to the real-time of interior
Humidity determine, coil pipe target temperature is small during real-time high humidity so that indoors during high humidity control coil pipe approach and maintain compared with
Low target temperature, to condense the moisture in more air, reaches reduction air humidity, further improves indoor air pleasant
The purpose of property.
As preferred embodiment, coil pipe target temperature is determined according to indoor real-time humidity, specifically included：
Indoor real-time humidity is obtained, real-time humidity is made comparisons with comfort humidity scope.Comfort humidity scope is known, pre-
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.
Wherein, it is a temperature that is known, prestoring to recommend coil pipe target temperature, general, is research staff's warp
One of heat exchange air that a large amount of theoretical researches and experiment test are obtained, that proper temperature can be sent out under comfort humidity
Coil temperature.Certainly, the recommendation coil pipe target temperature can also be changed by mandate, for example, by personnel after sale in user
Modified by special instruction in family.
Adopt when coil pipe target temperature is determined according to real-time humidity with the aforedescribed process, if humidity belongs to comfortable wet in real time
Degree scope, then using recommendation coil pipe target temperature as actual coil pipe target temperature, it is ensured that obtained when disk temperature PID control is performed
Suitable air conditioning exhausting.And if humidity is not belonging to comfort humidity scope in real time, and humidity is more than comfort humidity scope in real time
Higher limit, for example, more than 60%, shows that now indoor humidity is larger.In this case, coil pipe target temperature is reduced, specifically
Will be less than the actual coil pipe target temperature for recommending the temperature of coil pipe target temperature to be defined as performing disk temperature PID arithmetic.If in real time
Humidity is not belonging to comfort humidity scope and humidity, less than the lower limit of comfort humidity scope, preferably will also recommend coil pipe mesh in real time
Temperature is marked as actual coil pipe target temperature, to ensure the air conditioning exhausting of acquisition proper temperature.
It should be noted that during dual PID control is performed, still constantly comparing the second indoor temperature and relaxing
The size of thermophilic degree.Once indoor temperature is not less than comfort temperature, then dual PID control process is exited, be transferred to room temperature PID control
Process processed.
And, in whole control process, not compressor runs the compensation for being carried out indoor temperature at the beginning, but first
Compressor is kept to be run according to conventional control strategy, it is ensured that indoor temperature can be according to conventional control mode, be rapidly close to
Indoor target temperature, does not interfere with the speed of indoor temperature comfort conditioning.
