The present invention is described in further detail.
Fig. 1 is referred to, the figure show the present invention and realizes method one embodiment that air conditioner refrigerating is controlled based on distance
Flow chart.
As shown in figure 1, the embodiment realizes the method for air conditioner refrigerating control using the stream with following step based on distance
Journey is realized：
Step 11：Air conditioner refrigerating runs, and obtains real-time indoor environment temperature, setting indoor target temperature, meanwhile, real-time detection is empty
Adjust thermal source indoors and determine the real-time range of thermal source and air conditioning room.
Specifically, when air-conditioning is started shooting and run, the indoor environment temperature in room, real-time detection residing for real-time detection air-conditioning
Temperature as real-time indoor environment temperature.So-called real-time indoor environment temperature, refers to after air-conditioning start operation, according to setting
The indoor environment temperature that constant temperature degree sample frequency is constantly obtained and updated.The acquisition of real-time indoor environment temperature can use existing
Technology is realized.For example, being detected into wind-warm syndrome by being arranged on air-conditioning air inlet or being close to the temperature sensor of air-conditioning air inlet
Degree, the master control borad of air-conditioning passes through the output signal of collecting temperature sensor and is processed, so as to get EAT, and will
The temperature is used as real-time indoor environment temperature.
Setting indoor target temperature refers to wish the indoor environment target temperature to be reached, the setting indoor target temperature

The automatic setting value called of control plate.No matter the temperature value is set using which kind of mode, can be got by air-conditioning master control borad.
After air-conditioning start operation, except the real-time indoor environment temperature in room residing for real-time detection air-conditioning, also to examine in real time
Survey air-conditioning thermal source indoors, and determine the real-time range of thermal source and air conditioning room.So-called real-time range, is opened in air-conditioning
After machine operation, the distance between indoor airflow and air-conditioning for constantly obtaining and update according to setting sample frequency.The detection of thermal source
And thermal source can be realized with the determination of distance of air conditioning room using prior art.For example, by setting infrared battle array on air-conditioning
Sensor or common infrared sensor, calculate with reference to certain algorithm.
As preferred embodiment, detection air-conditioning thermal source indoors and determine between thermal source and air-conditioning it is real-time away from
From, obtained using following technological means, specifically include：
Infrared sensor in control air-conditioning carries out rotary scanning, the temperature information in sweep limits is obtained, according to temperature information
Obtain heat source temperature curve.
Specifically, infrared sensor and rotating mechanism, the controller control rotating machine of air-conditioning can be set on air-conditioning
Structure drives infrared sensor to be rotated in larger angular range.The infrared sensor of rotation is to the region in the range of scanning angle
It is scanned, the temperature information of Real-time Collection scanning area.Temperature information reflection is sweeping for infrared sensor currently collection
The radiation intensity of object in the range of retouching, radiation intensity is stronger, then it represents that the temperature value of infrared sensor collection is higher.Therefore, exist
In the scanning process of infrared sensor, scanning to the process after thermal source, infrared sensing is arrived again to source center before scanning to thermal source
The temperature value of device sampling is to arrive a low process again from low to high, and this is scanning a to process for thermal source.Air-conditioning receives red
The temperature information of outer sensor sampling, is generated indoor by the analysis of the i.e. radiation intensity of temperature information gathered to infrared sensor
The temperature curve of thermal source.
Infrared sensor is driven to rotate by rotational structure, so only needing to single-point infrared sensor is capable of achieving whole sky
Between scope temperature scanning, it is not necessary to array infrared sensor, data processing is relatively simple, expend the time it is short.
Then, according to heat source temperature curve determine air-conditioning between thermal source indoors and thermal source and air-conditioning it is real-time away from
From.
Specifically, by the crest value in analysis temperature curve, crest value corresponds to the radiation intensity of thermal source to air-conditioner, according to
Crest value may determine that the number of thermal source in current environment, wherein, the coordinate value of crest value is the coordinate value i.e. position of thermal source.
And, temperature value and the distance of object of infrared sensor sampling have relation, when object distance air-conditioning is more remote, infrared sensing
The temperature value of device collection is lower, conversely, closer to object true temperature value.Specifically, can be according to temperature in temperature curve most
Difference between high level and minimum determines the distance between thermal source and air-conditioner, is gathered according to infrared sensor in the scan period
The maximum of temperature value and the difference of minimum value can interpolate that the thermal source of Current Scan and the relative distance of background, difference is got over
It is small, illustrate that thermal source and background are approached, i.e., thermal source is with air-conditioning farther out.
Step 12：The temperature difference between real-time indoor environment temperature and setting indoor target temperature is calculated, as real-time interior
The temperature difference, room temperature PID computing is carried out according to the real-time indoor temperature difference, obtains first frequency；It is corresponding with wind speed according to known distance
Relation determines wind speed corresponding with real-time range and as real-time wind speed, and the corresponding relation according to known wind speed and frequency is obtained
Frequency corresponding with real-time wind speed, as second frequency.
Master control borad calculates temperature between the two after real-time indoor environment temperature and setting indoor target temperature is got
Difference, as the real-time indoor temperature difference.Then, room temperature PID computing is carried out according to the real-time indoor temperature difference, acquisition is controlled to compressor
A frequency, and the frequency is defined as first frequency.Wherein, room temperature PID computing carried out according to the temperature difference, obtained to compressor
The specific method of the target frequency being controlled can be realized using prior art, not be elaborated herein and limit.
Meanwhile, wind speed corresponding with real-time range is obtained with the corresponding relation of wind speed always according to known distance, as reality
When wind speed.Specifically, the corresponding relation of distance and wind speed is previously stored with the memory of air-conditioning master control borad, wherein, away from
From referring to the distance between indoor airflow and air-conditioning, wind speed refers to the speed of indoor unit fan of air conditioner operating.For it is different away from
From to that should have wind speed that is incomplete same or differing completely, and distance is bigger, and wind speed is lower.Also, it is preferred that, distance with
The corresponding relation of wind speed be by research staff under theoretical direction, by substantial amounts of operation of air conditioner simulated experiment obtained by, energy
It is enough to take into account air-conditioning comfortableness and energy saving as far as possible.Therefore, it is corresponding with wind speed from distance after real-time range is obtained
Real-time range is first found in relation, the wind speed corresponding to the real-time range is then obtained, and using the wind speed as real-time wind speed.
Then, frequency corresponding with real-time wind speed is obtained with the corresponding relation of frequency according to known wind speed, as second frequency.
Specifically, the corresponding relation of wind speed and frequency is also previously stored with the memory of air-conditioning master control borad, wherein,
Wind speed refers to the speed of indoor unit fan of air conditioner operating, and frequency refers to the running frequency of compressor.For different wind speed, correspondence
There are different frequencies.Also, it is preferred that, wind speed and the corresponding relation of frequency be by research staff under theoretical direction, through excessive
Obtained by the operation of air conditioner simulated experiment of amount, air-conditioning comfortableness and energy saving can be as far as possible taken into account.Set up wind speed with
The starting point of the corresponding relation of frequency is：For air-conditioning system, if indoor machine fan rotating speed is certain, blower fan operating is driven
Dynamic air-flow is certain, that is, air quantity is certain；Air quantity is certain, the heat exchange formed with heat exchanger when it is by indoor set heat exchanger
Ability is certain.If compressor operating frequency is too small, refrigerant circulation is very few, can reduce the exchange capability of heat of indoor heat exchanger, makes
Indoor wind pushing temperature is obtained to be not suitable for.And if compressor operating frequency is excessive, refrigerant circulation is big, indoor heat exchanger exchange capability of heat
Greatly, but because the air quantity produced under certain interior machine rotating speed is too small, heat exchanger heat exchange efficiency can be caused to decline, and the big work(of compressor
Rate operation wastes energy consumption.Therefore, it is necessary to and restriction corresponding with frequency work to wind speed.
Therefore, after real-time wind speed is obtained, real-time wind speed is first found from the corresponding relation of wind speed and frequency, then
Obtain the frequency corresponding to the real-time wind speed, and using the frequency as second frequency.
And, a wind speed may correspond to a frequency, it is also possible to correspondence multiple frequency.If wind speed correspond to many
Individual frequency, a namely real-time wind speed is to that should have multiple frequencies, in this case, peak frequency in the multiple frequencies of selection is used as the
Two frequencies.
Step 13：Judge real-time indoor environment temperature whether less than setting comfort temperature.If so, performing step 15；If
It is no, perform step 14.
The step can simultaneously be carried out with step 12, and two steps are divided into herein merely to clearly stating the reality
Apply the control process of example.After step 11 gets real-time indoor environment temperature, real-time indoor environment temperature is relaxed with setting
Whether thermophilic degree is made comparisons, and judges real-time indoor environment temperature less than setting comfort temperature, to be performed according to comparative result
The control of step 14 or step 15.Wherein, setting comfort temperature can be a default setting temperature of air-conditioning when dispatching from the factory, and also may be used
Voluntarily being selected and a design temperature setting by user.If by user's sets itself, air-conditioning can provide one
Reference temperature value, it is for reference.For example, it is proposed that the comfort temperature is set as 27 DEG C.
Step 14：If step 13 judges that real-time indoor environment temperature, not less than setting comfort temperature, is performed following
First control：Smaller value in selection first frequency and second frequency controls air-conditioning as target frequency according to target frequency
Compressor operating.
If real-time indoor environment temperature is not less than setting comfort temperature, show that now indoor temperature is higher, it is necessary to quick
Cooling.In this case, the smaller value in both first frequency and second frequency that comparison step 12 is obtained, selection, as target
Frequency, the compressor operating of air-conditioning is controlled according to target frequency.
Step 15：If step 13 judges real-time indoor environment temperature less than setting comfort temperature, following the is performed
Two controls：The real-time coil temperature and setting coil pipe target temperature of A/C evaporator are obtained, real-time coil temperature and coil pipe is calculated
The temperature difference between target temperature, as the real-time coil pipe temperature difference, disk temperature PID arithmetic is carried out according to the real-time coil pipe temperature difference, obtains the 3rd
Frequency, the smaller value in selection first frequency, second frequency and the 3rd frequency is controlled empty as target frequency according to target frequency
The compressor operating of tune.
If step 13 judges that indoor temperature is less than comfort temperature, to avoid the too fast decline of temperature from causing body-sensing uncomfortable,
Evaporator coil temperature is further considered, to adjust compressor operating frequency in time so that evaporator coil temperature can be steady
Surely coil pipe target temperature is arrived, to adjust air conditioning exhausting temperature, is reached cool without cold comfortable air-out effect.
Specifically, first, the real-time coil temperature and coil pipe target temperature of A/C evaporator are obtained, real-time coil pipe is calculated
The temperature difference between temperature and coil pipe target temperature, as the real-time coil pipe temperature difference, disk temperature PID fortune is carried out according to the real-time coil pipe temperature difference
Calculate, obtain the 3rd frequency.
Wherein, the detection of evaporator coil temperature can be detected by setting coil temperature sensor on an evaporator.
Real-time detection goes out after coil temperature, the temperature difference between real-time coil temperature and setting coil pipe target temperature is calculated, by the temperature difference
As the coil pipe temperature difference.Wherein, coil pipe target temperature determines in real time according to indoor real-time humidity, and when meeting real-time high humidity
Coil pipe target temperature is small.Then, disk temperature PID arithmetic is carried out according to the coil pipe temperature difference, the target that acquisition is controlled to compressor is frequently
Rate, and the target frequency is defined as the 3rd target frequency.Disk temperature PID arithmetic obtains the target frequency being controlled to compressor
The method method that may be referred to room temperature PID computing of the prior art and obtain compressor target frequency.Wherein, disk temperature PID
The original frequency of computing can be an original frequency for setting.Preferably, the original frequency of disk temperature PID arithmetic is sentenced for step 12
Fixed real-time indoor environment temperature is less than setting comfort temperature, the current operation frequency into compressor during the second control process.And
And, the current operation frequency is at least in compressor operating for a period of time（Such as 3min）A running frequency afterwards.
Then, the smaller value in selection first frequency, second frequency and the 3rd frequency is used as target frequency, according to target frequently
Rate controls the compressor operating of air-conditioning.
Frequency of air condition compressor is controlled using the above method, has been considered between temperature factor and wind speed factor
Coordinate so that during compressor operating drive refrigerant produced by heat exchange amount with should during blower fan operating driving air-flow formed
Heat exchange amount match, it is to avoid press frequency is too high or rotation speed of fan it is too high produced by meaningless energy consumption, realize air-conditioning
Energy-saving run.And, wind speed is controlled according to thermal source with the distance of air conditioning room, also improves the comfortableness of air-supply and relaxing for user
Appropriateness.Additionally, in control for temperature factor to compressor frequency, it is big with setting comfort temperature according to indoor environment temperature
It is small, selection using room temperature PID control or using based on evaporator coil temperature disk temperature PID control, can when room temperature is high and
When, quickly room is lowered the temperature, reach refrigeration purpose, again can be by coil temperature stabilization in coil pipe target temperature so that empty
Recall air temperature comfortable, reach cool without cold comfortable cooling effect.And, the coil pipe mesh during disk temperature PID control
Mark temperature determines that coil pipe target temperature is small during real-time high humidity so that high humidity time control indoors according to indoor real-time humidity
Coil pipe processed is approached and maintains relatively low target temperature, to condense the moisture in more air, is reached reduction air humidity, is entered
One step improves the purpose of indoor air pleasant.
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.
And, during the second control is performed, real-time indoor environment temperature is still constantly obtained, and it is relatively more real-time
Indoor environment temperature and the size for setting comfort temperature.Once real-time indoor environment temperature is then moved back not less than setting comfort temperature
Go out the second control process, be transferred to the first control process, to cause indoor temperature stabilization in setting indoor target temperature.
As preferred embodiment, in real-time indoor environment temperature not less than comfort temperature and real-time indoor environment temperature
When the difference of degree and setting comfort temperature is more than setting difference, then the second control process is exited, be transferred to the first control process.Pass through
Reasonable selection sets 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
Without cold comfortableness.
As preferred implementation method, a setting highest frequency is previously stored with the memory of air-conditioning master control borad,
If step 14 judges that the smaller value in first frequency and second frequency judges first more than setting highest frequency, or step 15
Smaller value in frequency, second frequency and the 3rd frequency more than setting highest frequency, then will setting highest frequency as target frequently
Rate.That is, either according to which FREQUENCY CONTROL compressor, ensureing the running frequency of compressor no more than setting highest
Frequency.
