Specific implementation mode
Technical scheme of the present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is referred to, which show the flow chart of air conditioner refrigerating control method one embodiment of the present invention.
As shown in Figure 1, the embodiment realizes that the detailed process of the method for air conditioner refrigerating control is as follows：
Step 11：Air conditioner refrigerating is run, and obtains real-time indoor environment temperature and setting indoor target temperature；Meanwhile in real time
Indoor heat source where detecting air-conditioning, and determine the real-time range of heat source and air conditioning room.
Specifically, when air-conditioning is switched on and runs, the indoor environment temperature in room residing for air-conditioning is detected in real time, is detected in real time
Temperature as real-time indoor environment temperature.So-called real-time indoor environment temperature refers to after air-conditioning booting operation, according to setting
Constant temperature degree sample frequency constantly obtains and newer indoor environment temperature.The acquisition of real-time indoor environment temperature may be used existing
Technology is realized.For example, by being arranged in air-conditioning air inlet or being detected into wind-warm syndrome close to the temperature sensor of air-conditioning air inlet
Degree, the master control borad of air-conditioning is by the output signal of collecting temperature sensor and is handled, to get inlet air temperature, and will
The temperature is as real-time indoor environment temperature.
Setting indoor target temperature refers to wishing the attainable target temperature of indoor environment institute, the setting indoor target temperature

After air-conditioning booting operation, the real-time indoor environment temperature in addition to detecting room residing for air-conditioning in real time will also be examined in real time
Indoor heat source where surveying air-conditioning, and determine the real-time range of heat source and air conditioning room.So-called real-time range is switched in air-conditioning
After operation, according to setting sample frequency constantly acquisition and the distance between newer indoor airflow and air-conditioning.The detection of heat source and
The prior art may be used to realize in the determination of distance of heat source and air conditioning room.For example, by the way that infrared array is arranged on air-conditioning
Sensor or common infrared sensor, calculate in conjunction with certain algorithm.
As preferred embodiment, indoor heat source where detection air-conditioning and determine between heat source and air-conditioning it is real-time away from
From being obtained, specifically included using following technological means：
The infrared sensor controlled in air-conditioning carries out rotary scanning, the temperature information in scanning range is obtained, according to temperature
Information acquisition heat source temperature curve.
Specifically, infrared sensor and rotating mechanism can be arranged on air-conditioning, the controller of air-conditioning controls rotating machine
Structure driving infrared sensor rotates in larger angular range.The infrared sensor of rotation is to the region within the scope of scanning angle
It is scanned, the temperature information in real-time acquisition scans region.Temperature information reflection is sweeping of currently acquiring of infrared sensor
The radiation intensity of object in range is retouched, radiation intensity is stronger, then it represents that the temperature value of infrared sensor acquisition is higher.Therefore, exist
In the scanning process of infrared sensor, scanning is arrived again to the process after heat source, infrared sensing to source center before scanning to heat source
The temperature value of device sampling is to arrive a low process again from low to high, this is process of the scanning to a heat 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 acquired to infrared sensor
The temperature curve of heat source.
Infrared sensor rotation is driven by rotational structure, so only needing single-point infrared sensor that entire sky can be realized
Between range temperature scanning, do not need array infrared sensor, data processing is relatively simple, expend the time it is short.
Then, according to heat source temperature curve determine where air-conditioning between indoor heat source and heat source and air-conditioning it is real-time away from
From.
Specifically, for air conditioner by the crest value in analysis temperature curve, crest value corresponds to the radiation intensity of heat source, according to
Crest value may determine that the number of heat source in current environment, wherein the coordinate value of crest value is the coordinate value i.e. position of heat source.
Moreover, the temperature value of infrared sensor sampling and the distance of object have relationship, and when object distance air-conditioning is remoter, infrared sensing
The temperature value of device acquisition is lower, conversely, closer to object true temperature value.It specifically, can be according to temperature in temperature curve most
Difference between high level and minimum determines the distance between heat source and air conditioner, is acquired according to infrared sensor in the scan period
The maximum value of temperature value and the difference of minimum value can judge that the heat source of Current Scan and the relative distance of background, difference are got over
It is small, illustrate that heat source and background are close, i.e., heat source with air-conditioning farther out.
Step 12：It calculates real-time indoor environment temperature and sets the temperature difference between indoor target temperature, as real-time interior
The temperature difference carries out room temperature PID operation according to the real-time indoor temperature difference, obtains first frequency.
Master control borad calculates temperature between the two after getting real-time indoor environment temperature and setting indoor target temperature
Difference, as the real-time indoor temperature difference.Then, room temperature PID operation is carried out according to the real-time indoor temperature difference, acquisition controls compressor
A frequency, and the frequency is defined as first frequency.Wherein, room temperature PID operation carried out according to the temperature difference, obtained to compressor
The prior art may be used to realize in the specific method of the target frequency controlled, is not elaborated and limits herein.
Step 13：Judge whether real-time range is less than setpoint distance.If so, executing step 15；If it has not, executing step
14。
The step can be carried out at the same time with step 12, be divided into two steps herein merely to clearly stating the reality
Apply the control process of example.After step 11 gets real-time range, real-time range is made comparisons with setpoint distance, and judge reality
When distance whether be less than setpoint distance, to execute the control of step 14 or step 15 according to comparison result.Wherein, setpoint distance
One default setting distance of air-conditioning when can be manufacture, can also be voluntarily selected by user and be arranged one setting away from
From.If it is by user's sets itself, air-conditioning can provide a reference value, for reference.Such as, it is proposed that the distance is set
It is set to 3m.
Step 14：If step 13 judges that real-time range is not less than setpoint distance, the first following control is executed：Selection
First frequency controls the compressor operating of air-conditioning.
If real-time range be not less than setpoint distance, show at this time heat source apart from air-conditioning farther out, for ensure heat source at system
Cold effect needs air outlet temperature relatively low, to send out at enough cooling airs to heat source.In this case, selection is passed through room
The first frequency that warm PID is calculated controls the compressor operating of air-conditioning as target frequency.Also, in this case, due to heat
Farther out apart from air-conditioning, even if air outlet temperature is low, the wind of submitting is blown to by a distance at heat source in source, will not be too cool and influence
User's comfort.
Step 15：If step 13 judges that real-time range is less than setpoint distance, the second following control is executed：It obtains empty
The real-time coil temperature for adjusting evaporator determines and real-time range pair according to the correspondence of known distance and coil pipe target temperature
The coil pipe target temperature answered is calculated as real-time coil pipe target temperature between real-time coil temperature and real-time coil pipe target temperature
The temperature difference carries out disk temperature PID arithmetic according to the real-time coil pipe temperature difference, obtains second frequency as the real-time coil pipe temperature difference, selects the first frequency
Smaller value in rate and second frequency controls the compressor operating of air-conditioning according to target frequency as target frequency.
If step 13 judges that real-time range is less than setpoint distance, 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, reaches cool without cold comfortable air-out effect.
Specifically, first, the real-time coil temperature of A/C evaporator is obtained, and according to known distance and coil pipe target
The correspondence of temperature determines coil pipe target temperature corresponding with real-time range as real-time coil pipe target temperature；Then, it calculates
The temperature difference between coil temperature and real-time coil pipe target temperature in real time, as the real-time coil pipe temperature difference, according to the real-time coil pipe temperature difference into
Row disk temperature PID arithmetic obtains second frequency；Finally, the first frequency and the second frequency that selection is obtained according to room temperature PID operation
In smaller value as target frequency, compressor of air conditioner operation is controlled according to target frequency.
Wherein, the detection of evaporator coil temperature can be detected by the way that coil temperature sensor is arranged on an evaporator.
And the method that disk temperature PID arithmetic obtains the target frequency controlled compressor can refer to room temperature PID in the prior art
Operation and the method for obtaining compressor target frequency.Wherein, the original frequency of disk temperature PID arithmetic can be set initial for one
Frequency.Preferably, the original frequency of disk temperature PID arithmetic is that judgement real-time range is less than setpoint distance, controls process into second
When compressor current operation frequency.Moreover, the current operation frequency at least compressor operating for a period of time（Such as 3min）
A running frequency later.Coil pipe target temperature is not changeless temperature, but at a distance from heat source and air conditioning room
A corresponding variable temperature.Specifically, distance and coil pipe target are previously stored in the memory of air-conditioning master control borad
The correspondence of temperature, wherein distance refers to the distance between indoor airflow and air-conditioning, and coil pipe target temperature is it is expected evaporator
Coil temperature institute temperature to be achieved.For different distances, it is corresponding with not exactly the same or complete different coil pipe target
Temperature, and apart from smaller, coil pipe target temperature is bigger, it is therefore an objective to it is provided for the heat source at different distance and more suitably goes out wind-warm syndrome
Degree, ensures the comfort of outlet air.Moreover, by the variation of coil pipe target temperature, additionally aid by reducing compressor operating frequency
Rate reduces operation of air conditioner energy consumption.Preferably, the correspondence of distance and coil pipe target temperature is referred in theory by research staff
It leads down, is obtained by a large amount of operation of air conditioner simulated experiment, air-conditioning comfort can be taken into account as far as possible.Therefore, exist
After obtaining real-time range, real-time range is first found from correspondence of the distance with coil pipe target temperature, then obtaining should
Coil pipe target temperature corresponding to real-time range, and using the coil pipe target temperature as real-time coil pipe target temperature.
Air conditioner refrigerating control, real-time range and setpoint distance by comparing heat source apart from air-conditioning are realized using the above method
Size do not consider disk temperature PID control when real-time range is not less than setpoint distance and control compressor only with room temperature PID
Operation avoids the problem that poor refrigerating efficiency to rapidly be cooled down to room, and is not more than setpoint distance in real-time range
When, consider disk temperature PID control so that air conditioning exhausting temperature pleasant reaches cool without cold comfortable cooling effect.Moreover,
During disk temperature PID control, disk temperature target temperature is adaptively adjusted according to the real-time range of heat source and air conditioning room, further carries
The high comfort of leaving air temp, it helps reduce operation of air conditioner energy consumption.
Moreover, during executing the second control, the real-time range of heat source and air conditioning room is still constantly detected in real time,
And compare real-time range and the size of setpoint distance.Once real-time range is not less than setpoint distance, then the mistake of the second control is exited
Journey, and the process of the first control is executed, so that indoor temperature is stablized in setting indoor target temperature.
As preferred embodiment, during executing the second control, real-time range not less than setpoint distance and
When real-time range and the difference of setpoint distance are more than setting difference, the second control is exited, executes the first control.
