Description of the drawings
Fig. 1 is the flow chart based on control method one embodiment of air-conditioning 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 based on control method one embodiment of air-conditioning of the present invention, concrete next
Say be refrigerating of convertible frequency air conditioner control method flow chart.
As shown in figure 1, the embodiment realizes that the detailed process of air conditioning control method is as follows：
Step 1：Air-conditioning enters refrigeration mode, and refrigerating operaton detects indoor temperature, and makes comparisons with the comfort temperature of setting.
Specifically, when air-conditioning is started shooting and runs refrigeration mode, the indoor temperature in room residing for air-conditioning is detected.The interior
The detection of temperature is realized using prior art.For example, by being arranged on air-conditioning air inlet or near air-conditioning air inlet
Temperature sensor detects EAT, used as indoor temperature.
After detecting indoor temperature, indoor temperature is made comparisons with the comfort temperature of setting.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 arranging.Such as
Fruit is that, by user's sets itself, air-conditioning can provide reference temperature value, for reference.Also, it is preferred that giving 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 indoor temperature whether less than comfort temperature.If so, execution step 4；Otherwise, execution step 3.
Step 3：If indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, conventional refrigerant will be performed.
Then, execution step 5.
Specifically, the temperature difference first between the indoor temperature and the indoor target temperature of setting of the detection of calculation procedure 1, will
The temperature difference is used as the indoor temperature difference.Wherein, indoor target temperature refers to the target temperature that user sets, expectation interior is reached.
Then, room temperature PID computing is carried out according to the indoor temperature difference, obtains the target frequency being controlled to compressor, and by target frequency
Rate is defined as first object frequency.Wherein, carry out room temperature PID computing, acquisition according to the indoor temperature difference to be controlled compressor
The concrete grammar of target frequency can realize that here is not elaborated and limits using prior art.So as to so that it is indoor
Temperature can drop quickly to indoor target temperature.
If indoor temperature is less than comfort temperature, by execution step 4 and the comfortable cooling of step 5.
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 cooling process of the dual PID control of row, to adjust compressor operating frequency in time so that evaporator coil temperature can
Coil pipe target temperature is stabilized to, to adjust air conditioning exhausting temperature, cool and not cold comfortable air-out effect is reached.Comfortable cooling is controlled
Process referring to below step 4 and step 5 description.
Step 4：The coil temperature of detection evaporimeter, according to the coil pipe temperature difference disk temperature PID arithmetic is carried out, and obtains the second target frequency
Rate.
The detection of the coil temperature of evaporimeter can be detected by arranging temperature sensor on evaporator coil.Detection
After going out 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 according to indoor target temperature, and it is also little to meet indoor target temperature hour coil pipe target temperature.So
Afterwards, 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 frequency
It is defined as the second target frequency.Disk temperature PID arithmetic obtains the method for the target frequency being controlled to compressor and may be referred to now
The method for having the room temperature PID computing in technology and obtaining compressor target frequency.Wherein, the original frequency of disk temperature PID arithmetic can
Think the original frequency of a setting.Preferably, the original frequency of disk temperature PID arithmetic is that step 2 judges indoor temperature less than easypro
Thermophilic degree, the current operation frequency for performing compressor when comfortable cooling is controlled.And, the current operation frequency is at least in compression
Machine operation a period of time（Such as 3min）A running frequency afterwards.
Step 5：According to the smaller value in the second target frequency that the first object frequency that step 3 is calculated is calculated with step 4
Control compressor.
When indoors temperature is less than comfort temperature, disk temperature PID arithmetic is performed according to coil temperature and coil pipe target temperature, and
According to the smaller value control in the first object frequency of room temperature PID computing output and the second target frequency of disk temperature PID arithmetic output
Compressor operating processed, while refrigeration cool-down coil temperature is adjusted so that coil temperature can be approached to coil pipe target temperature.
Step 6：During above-mentioned conventional refrigerant or comfortable cooling, human body temperature is detected, and judge that human body temperature is
No exception.If abnormal, execution step 8 raises indoor target temperature, and performs refrigeration according to the indoor target temperature after rising
Control；Otherwise, execution step 7, keep indoor target temperature constant, continue executing with refrigeration control.
Refrigeration control is carried out to air-conditioning using said process, when indoors temperature is higher, compressor is controlled using room temperature PID
Operation so that indoor temperature fast cooling simultaneously approaches indoor target temperature.When indoors temperature is less than comfort temperature, using room temperature
The dual PID control of PID control and disk temperature PID control：When disk temperature PID control is had just enter into, disk temperature PID control plays main work
With preferentially rising to coil temperature to approach coil pipe target temperature while cooling；And in the close coil pipe target of coil temperature
During temperature, room temperature PID plays a major role so that the stable target temperature indoors of indoor temperature, it is to avoid cause because of room temperature overshoot
Air-conditioning shuts down the generation of phenomenon.So that during whole refrigeration control, indoor temperature is caused indoor target temperature is approached
On the basis of cause coil temperature approach coil pipe design temperature, both met room temperature regulation, the comfortableness of air conditioning exhausting is realized again, reach
Go out cool and not cold refrigeration.And, the coil pipe target temperature during disk temperature PID control according to indoor target temperature come
It is determined that, indoor target temperature hour coil pipe target temperature is also little so that coil pipe target temperature is consistent with indoor target temperature,
Cooling rate is fast when performing disk temperature PID control in the case that target temperature requirement indoors is low, is rapidly achieved required interior
The balance of low temperature, further improves user's comfortableness.Additionally, during refrigeration control, human body temperature is detected, according to human temperature
Whether degree there is exception to decide whether to raise indoor target temperature, so that the control of air-conditioning more flexible, hommization, enters
One step improves refrigeration comfortableness.
Used as preferred embodiment, coil pipe target temperature determines according to indoor target temperature, specifically includes：
Obtain indoor recommendation target temperature and coil pipe recommends target temperature；
The difference of indoor recommendation target temperature and indoor target temperature is calculated, as the first difference；
Second difference is obtained according to the differences of the second difference of formula=a* first；A is no more than 1 positive number；
The difference that coil pipe recommends target temperature and the second difference is calculated, result of calculation is defined as performing the actual disk of disk temperature PID arithmetic
Pipe target temperature.
Wherein, indoor recommendation target temperature be known, a temperature prestoring, be research staff Jing usually
It is that a large amount of theoretical researches and experiment test are obtained, take into account human body comfort and a temperature of air conditioner energy saving, be 27 for example
℃.The temperature that it is also known that coil pipe recommends target temperature, prestored, is that research staff Jing is theoretical in a large number usually
Research and experiment test obtained, indoors recommend target temperature as actual set indoor target temperature when can send
One coil temperature of the heat exchange air of proper temperature, is 14 DEG C for example.Certainly, the indoor recommendation target temperature is pushed away with this
Recommending coil pipe recommends target temperature to be changed by mandate, for example, by personnel after sale special finger is passed through in user family
Order is modified.A is also known, prestores as a coefficient according to first the second difference of mathematic interpolation, its value
, it is that a large amount of theoretical researches of research staff Jing and experiment test are obtained.Preferably, a is the positive number less than 1, and for example, a takes
It is worth for 0.5.So, recommend target temperature to be 27 DEG C indoors, indoor recommendation coil pipe target temperature be 14 DEG C, the situation that a is 0.5
Under, if actual indoor target temperature is 26 DEG C, actual coil pipe target temperature is 13.5 DEG C；If indoor target temperature is 25
DEG C, then actual coil pipe target temperature is 13 DEG C.
Adopt with the aforedescribed process, when coil pipe target temperature is determined according to indoor target temperature, if indoor target temperature
Less than indoor recommendation target temperature, show that current desired indoor temperature is low, indoor recommendation target temperature and indoor objects temperature
The first difference between degree is negative value, is also negative value according to the first mathematic interpolation the second difference out；So, it is poor according to second
Value and coil pipe recommend the actual coil pipe target temperature that target temperature is calculated to recommend target temperature less than coil pipe.So,
When then performing disk temperature PID arithmetic according to actual coil pipe target temperature, because coil pipe target temperature is little, compressor operating frequency is big,
Cooling rate is fast, so that indoor temperature can rapidly reach required relatively low indoor temperature, meets to low
The comfortableness of the user of warm demand.And, indoor target temperature is lower, and the coil pipe target temperature for being obtained is also lower so that disk
The speed and cooling demand of warm PID control process is consistent with room temperature PID control, further increases the comfortableness of user.
As preferred embodiment, if detecting human body temperature exception, air-conditioning alert and/or warning can also be controlled
Signal.For example, control air-conditioning and warning message is sent to user mobile phone by built-in communication unit, mobile phone is received after warning message
Alarm signal is sent by the method for light, vibration or sound.Or, control air-conditioning is sent by the warning device that itself is arranged
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 higher state.
Specifically, human body temperature is more than the first set temperature value including the temperature value of the predetermined patterns of human body first extremely.
For example, the first predetermined patterns are heads, and 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 realizing.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
The such as quilt of overcover herein is raised.Now, indoor target temperature is also raised automatically 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 value and the value corresponding to infant corresponding to 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, indoor target temperature is also raised automatically.
And, during dual PID control is performed, still constantly real-time detection indoor temperature, and it is relatively more indoor
The size of temperature and comfort temperature.Once indoor temperature is not less than comfort temperature, then the comfortable cooling for exiting dual PID was controlled
Journey, is transferred to the conventional refrigerant control process of room temperature PID, so that the stable indoor target temperature in setting of indoor temperature.
Used as preferred embodiment, indoors temperature is not less than the difference of comfort temperature and indoor temperature and comfort temperature
During more than the difference for setting, then dual PID comfortable coolings control process is exited, the conventional refrigerant for being transferred to room temperature PID was controlled
Journey.The difference set by reasonable selection, for example, is set as 1 DEG C, it can be ensured that coil temperature is not less than coil pipe target temperature,
Ensure cool and not cold comfortableness.
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.
Above example is only illustrating technical scheme, rather than is limited；Although with reference to aforementioned reality
Apply example to be described in detail the present invention, for the person of ordinary skill of the art, still can be to aforementioned enforcement
Technical scheme described in example is modified, or carries out equivalent to which part technical characteristic；And these are changed or replace
