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 air conditioning control method one embodiment of the present invention, specifically
The flow chart of refrigerating of convertible frequency air conditioner control method.
As shown in figure 1, the detailed process of the embodiment air conditioning control method is as follows：
Step 1：Air-conditioning enters refrigeration mode, and refrigerating operaton detects indoor temperature, and make to compare with the comfort temperature of setting
Compared with.
Specifically, when air-conditioning is started shooting and runs refrigeration mode, the indoor temperature in room residing for detection air-conditioning.The interior
The detection of temperature is realized using prior art.For example, by being arranged on air-conditioning air inlet or close to air-conditioning air inlet
Temperature sensor detects EAT, is used as indoor temperature.
Detect after indoor temperature, indoor temperature is made comparisons with the comfort temperature set.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 that, by user's sets itself, air-conditioning can provide reference temperature value, for reference.Also, it is preferred that being given for different groups
Go out different reference temperature values.For example：For children, it is proposed that the comfort temperature is set as into 26 DEG C；For old man, it is proposed that will relax
Thermophilic degree is set as 28 DEG C, etc..
Step 2：Judge whether indoor temperature is less than comfort temperature.If so, performing step 411；Otherwise, step 3 is performed.
Step 3：If indoor temperature is not less than comfort temperature, shows that now indoor temperature is higher, conventional refrigerant will be performed.
Then, step 5 is performed.
Specifically, the temperature difference between calculation procedure 1 is detected first indoor temperature and the indoor target temperature of setting, will
The temperature difference is used as the indoor temperature difference.Wherein, indoor target temperature refers to user's setting, the indoor target temperature reached of hope.
Then, room temperature PID computing is carried out according to the indoor temperature difference, obtains the target frequency being controlled to compressor, and by the target frequently
Rate is defined as first object frequency.Wherein, room temperature PID computing carried out according to the indoor temperature difference, obtain what compressor was controlled
The specific method of target frequency can be realized using prior art, be not elaborated and limited herein.So as to so that it is indoor
Temperature can drop quickly to indoor target temperature.
If indoor temperature is less than comfort temperature, comfortable cooling of the step 411 to step 414 will be performed.
If step 2 judges that indoor temperature is less than comfort temperature, to avoid the too fast decline of temperature from causing body-sensing uncomfortable, hold
The comfortable control of row, to adjust compressor operating frequency in time so that evaporator coil temperature can be stabilized to coil pipe target temperature
Degree, to adjust air conditioning exhausting temperature, reaches cool without cold comfortable air-out effect.Specifically, the process of comfortable cooling referring to
Below step 411 to step 414 description.
Step 411：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 412：Judge whether coil temperature is more than coil pipe target temperature.If so, performing step 413；Otherwise, step is performed
Rapid 414.
After step 411 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, a ginseng preferably to be provided by convertible frequency air-conditioner for the concept of coil temperature and its performance indications of representative in user
Temperature value is examined, it is for reference selected.For example, it is proposed that the coil pipe target temperature is set as 14 DEG C.
Step 413：If coil temperature is more than coil pipe target temperature, according to first object FREQUENCY CONTROL compressor.First
Target frequency refers to the target frequency obtained by step 3 room temperature PID computing.
If step 412 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 calculated according to room temperature PID.Then,
Perform step 5.
Step 414：If coil temperature is not more than coil pipe target temperature, the reduction of compressor current operation frequency is obtained the
Two target frequencies, the smaller value in the second target frequency and first object frequency controls compressor.Then, step 5 is performed.
If step 412 judges that coil temperature is not more than coil pipe target temperature, show that coil temperature is relatively low, be easily caused sky
Recall air temperature relatively low and send out cold wind.To solve the problem, compressor current operation frequency is reduced and the second target is obtained
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.
As preferred embodiment, in this embodiment, after the comfortable cooling of step 411 is entered, in advance
A highest frequency is set as the highest frequency of comfortable cooling, either according to first object frequency according further to the second target
FREQUENCY CONTROL compressor, ensures highest frequency of the frequency no more than setting of compressor.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.
Step 5：During above-mentioned conventional refrigerant or comfortable cooling, human body temperature is detected, and judge that human body temperature is
No exception.If abnormal, step 7 is performed, indoor target temperature is raised, and refrigeration is performed according to the indoor target temperature after rise
Control；Otherwise, step 6 is performed, keeps indoor target temperature constant, continues executing with refrigeration control.
If moreover, 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 is received to be passed through after warning message
The method of light, vibration or sound sends alarm signal.Or, the warning device that control air-conditioning is set by itself sends sound
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, such as
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
The problem is solved, the embodiment detects human body temperature in real time when air conditioner refrigerating is run, and it is different to judge whether human body temperature occurs
Often.If there is exception, indoor target temperature will be raised automatically so that room temperature maintains higher state.
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 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, shows 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 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 that head temperature and head temperature value are 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.
In addition, the temperature value that human body temperature can also include the predetermined patterns of human body second extremely is less than the 3rd design temperature
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 values corresponding with different user, for example, including the value corresponding to adult and the value corresponding to infant.
When judging the temperature value of the second predetermined patterns, first determine that human body is adult or infant according to infrared detections, for
Different human body is made comparisons from the set temperature value of different numerical value.
In addition, the temperature value that human body temperature can also include the predetermined patterns of human body second extremely is less than the 4th design temperature
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 of setting has been reached with the difference of the 4th set temperature value, then has shown that the second predetermined patterns are not covered.
Now, it is also automatic to raise indoor target temperature.
Refrigeration control is carried out to air-conditioning using said process, when temperature is higher indoors, compressor is controlled using room temperature PID
Operation so that indoor temperature fast cooling simultaneously approaches indoor target temperature；And when temperature is less than comfort temperature indoors, using base
Controlled in the comfortable cooling of evaporator coil temperature, the FREQUENCY CONTROL compressor of selection room temperature PID or reduction is causing interior
Cause coil temperature to approach coil pipe design temperature on the basis of temperature approaches indoor target temperature, both meet room temperature regulation, but it is real
The comfortableness of existing air conditioning exhausting, reaches cool without cold refrigeration.Moreover, during refrigeration control, detecting human body
Whether temperature, occur exception according to human body temperature to decide whether to raise indoor target temperature, so that the control of air-conditioning is more
Plus flexible, hommization, further increase refrigeration comfortableness.
It should be noted that during comfortable cooling control is performed, still constantly comparing indoor temperature and comfortable
The size of temperature.Once indoor temperature is not less than comfort temperature, then comfortable cooling control process is exited, conventional refrigerant control is transferred to
Process processed.
The flow chart of second embodiment of air conditioning control method of the present invention shown in Figure 2, specifically, this second
Individual embodiment is the idiographic flow controlled for comfortable cooling.Except first implementation of comfortable cooling control process and Fig. 1
Outside example is different, remaining room temperature PID computing, room temperature PID control, human body temperature detection, human body temperature unusual determination and processing
It is identical with one embodiment etc. process, it is not specifically addressed herein.Comfortable cooling control process only with regard to the embodiment below
Work is described below in detail：
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, going to step 427；Otherwise, step is performed
Rapid 423.
The step more specific description referring to Fig. 1 embodiment steps 412 description.
Step 423：Judge whether coil temperature is not more than coil pipe target temperature first.If so, performing 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 start
In, and according to the different processing of judged result execution.
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 minimum frequency of the minimum frequency for the setting in air conditioner refrigerating running.General, the minimum frequency of the refrigeration
Rate is the parameter set before air-conditioning dispatches from the factory.
Step 425：If coil temperature be start after it is non-first be not more than coil pipe target temperature, compressor is currently run
Frequency is reduced, 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
Second target frequency, is then chosen to be a frequency values between current operation frequency and refrigeration minimum frequency by rate.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 embodiment steps 3, and the second target frequency refers to root
According to target frequency determined by step 424 or step 425.Moreover, the refrigeration minimum frequency in step 424 is no more than the first mesh
Mark frequency a frequency values, thus, if coil temperature start after first be not more than coil pipe target temperature, control compressor with
The minimum frequency that freezes 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 comfortable cooling control, then coil temperature is not
Coil pipe target temperature can be less than very much, now, the second target frequency need not be minimized, but between current operation frequency and refrigeration
Between minimum frequency, to take into account the speed of room temperature regulation.
Need also exist for explanation, perform comfortable cooling control during, still constantly compare indoor temperature with
The size of comfort temperature.Once indoor temperature is not less than comfort temperature, then comfortable cooling control process is exited, conventional system is transferred to
Cold control process.
For the determination of the second target frequency in step 425, a variety of methods can be selected, it is preferred to use the side shown in Fig. 3
Method.
Refer to Fig. 3, the figure shows in Fig. 2 coil temperature it is non-first be not more than coil pipe design temperature after determine second
One particular flow sheet of target frequency.
As shown in figure 3, coil temperature is non-be not more than coil pipe design temperature first after determine the process of the second target frequency
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 used 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, realization by
Frequency after step section, and reduction is used 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, performing step
Rapid 4254；Otherwise, step 4255 is gone to.
After current operation frequency reduction 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, as it was previously stated, the tune that down conversion process process sets for interval
Whole time reduction is 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 reaching, 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 comfortable cooling control and entering conventional refrigerant control or shutdown.After adjustment time arrival, then read
Compressor current operation frequency is taken, based on current operation frequency, continues 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 influence 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
Conventional refrigerant control or shutdown are entered to comfortable cooling 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 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 is run.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although with reference to foregoing reality
Apply example the present invention is described in detail, for the person of ordinary skill of the art, can still implement to foregoing
