Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to drawings and examples,
The present invention is described in further detail.
Fig. 1 is referred to, the figure show the flow chart of heat-production control method one embodiment based on air conditioner of the present invention.
As shown in figure 1, the embodiment realizes that the detailed process for heating control is as follows：
Step 11：Air conditioner heat-production is run, and indoor temperature and outdoor temperature is obtained, by indoor temperature and the first inside temperature thresholds
Make comparisons, outdoor temperature is made comparisons with outdoor temperature threshold value.
Specifically, indoor temperature refers to when air conditioner is started shooting and runs heating mode, according to setting using frequency reality
When room residing for the air conditioner that obtains indoor temperature.The acquisition of the indoor temperature can be realized using prior art, for example,
By being arranged on air-conditioning air inlet or the temperature sensor detection close to the position of air-conditioning air inlet and acquisition EAT, make
For indoor temperature.When outdoor temperature refers to that air conditioner is started shooting and runs heating mode, case setting obtained in real time using frequency
Environment temperature residing for air conditioner outside room.The acquisition of the outdoor temperature can be realized using prior art, for example, by setting
The temperature sensor on air-conditioner outdoor unit is put to detect and obtain.
Then, indoor temperature and outdoor temperature are made comparisons with the first inside temperature thresholds and outdoor temperature threshold value respectively.
Wherein, the first inside temperature thresholds and outdoor temperature threshold value, as whether the threshold temperature of fuzzy control is performed, can be air-conditionings
A preset default temperature value in a control program or a temperature by air conditioner user's sets itself when device dispatches from the factory
Angle value.If by user's sets itself, preferably air conditioner recommends a reference temperature value, for reference.It is preferred that, it is preset
The first inside temperature thresholds or the first inside temperature thresholds of recommendation be 20 DEG C, preset outdoor temperature threshold value or the room of recommendation
Outer temperature threshold is 14 DEG C.
Step 12：Temperature is not more than the first inside temperature thresholds indoors and outdoor temperature is not more than outdoor temperature threshold value
When, perform fuzzy control.
Wherein, fuzzy control is specifically included：
The temperature difference between indoor temperature and setting indoor target temperature is calculated, the indoor temperature difference is obtained, room is carried out according to the indoor temperature difference
Warm PID arithmetic, obtains first object frequency.Indoor temperature is the indoor temperature acquired in step 11, sets indoor target temperature
Refer to user's setting, the indoor target temperature reached of expectation.And room temperature PID computing, acquisition pair are carried out according to the indoor temperature difference
The specific method for the target frequency that compressor is controlled can be realized using prior art, be not elaborated and limited herein
It is fixed.
Meanwhile, the coil temperature of indoor heat exchanger is obtained, and make comparisons with setting coil pipe target temperature.If coil temperature is big
In setting coil pipe target temperature, the first object frequency that room temperature PID computing is obtained is defined as indoor unit frequency；If coil temperature
Coil pipe target temperature is no more than set, the current operation frequency rise of compressor is obtained into the second target frequency, the first mesh is chosen
Higher value in mark frequency and the second target frequency is defined as indoor unit frequency；Then, according to indoor set FREQUENCY CONTROL air conditioner
Compressor.
The coil temperature of indoor heat exchanger is the coil pipe temperature using acquired in frequency, indoor set heat exchanger according to setting
Degree.The acquisition of coil temperature can be obtained by setting temperature sensor to detect in heat exchanger coils.Set coil pipe target temperature
Degree is to expect the coil pipe target temperature that can reach of indoor heat exchanger, can be when dispatching from the factory preset in a control program one it is silent
Recognize temperature value or a temperature value by air conditioner user's sets itself.If by user's sets itself, it is preferably empty
Device is adjusted to recommend a reference temperature value, it is for reference.It is preferred that, preset setting coil pipe target temperature or the setting disk of recommendation
Pipe target temperature range is 42-56 DEG C, and preferred value is 50 DEG C.
After comparing, if coil temperature is more than setting coil pipe target temperature, show that coil temperature is higher, then by coil temperature
The leaving air temp of the air conditioner of determination will not be too low, now, using the adjustment of indoor temperature as major control target, according to room temperature
PID calculates obtained first object frequency and is defined as indoor unit frequency, according to the compressor of indoor set FREQUENCY CONTROL air conditioner.Root
The detailed process for carrying out FREQUENCY CONTROL to cooler compressor according to indoor unit frequency refers to prior art.
If after comparing, coil temperature is not more than setting coil pipe target temperature, shows that coil temperature is not high enough, then by coil pipe
The leaving air temp for the air conditioner that temperature is determined is relatively low, and temperature of outlet air of air conditioner is also low in the case of easily causing because indoor temperature is low
And send out unfavorable air-out.In this case, lifting coil temperature is considered, it is also desirable to the mesh of both in-door temperature adjustment
's.Thus, the current operation frequency of compressor is raised, the second target frequency is obtained, by second target frequency and room temperature PID
The first object frequency that computing is obtained is made comparisons, and is chosen higher value therein and is defined as indoor unit frequency, according to indoor unit frequency
Control the compressor of air conditioner.The detailed process of FREQUENCY CONTROL is carried out to cooler compressor with reference to existing according to indoor unit frequency
Technology.Compressor current operation frequency is increased to the second target frequency, it is therefore an objective to by lifting frequency so that coil temperature to
Setting coil pipe target temperature is approached.When carrying out heating control to air conditioner using said process, if indoor temperature is not more than the
One inside temperature thresholds, outdoor temperature are not more than outdoor temperature threshold value, show current indoor temperature and current outdoor temperature compared with
It is low, fuzzy control will be performed, the frequency that the frequency of room temperature PID computing determination and the coil temperature based on indoor heat exchanger are determined is chosen
Larger frequency values control compressor in rate, temperature and causes compressor to be transported with high frequency when low coil temperature indoors
OK so that indoor temperature rapidly increases to convenient high temperature, it can cause that the leaving air temp of air conditioner will not be too low again, effectively
Indoor temperature is solved to rise the air-out blowout of slow and lower temperature and cause and heat the uncomfortable problem of body-sensing.Moreover, logical
Cross and use fuzzy control, relatively low indoor target temperature is set because of user misoperation when indoor temperature is relatively low
In the case of, also can by being judged based on coil temperature after raising frequency obtain controlling compressor high frequency fortune in the case of larger frequency values
OK, and by indoor temperature suitable high temperature is promoted to, air conditioner heat-production runnability is further improved.
Fig. 2 is referred to, the figure show the flow based on another embodiment of the heat-production control method of air conditioner of the present invention
Figure.
As shown in Fig. 2 the embodiment realizes that the detailed process for heating control is as follows：
Step 21：Air conditioner heat-production is run, and indoor temperature and outdoor temperature is obtained, by indoor temperature and the first inside temperature thresholds
Make comparisons, outdoor temperature is made comparisons with outdoor temperature threshold value.
Specifically, indoor temperature refers to when air conditioner is started shooting and runs heating mode, according to setting using frequency reality
When room residing for the air conditioner that obtains indoor temperature.The acquisition of the indoor temperature can be realized using prior art, for example,
By being arranged on air-conditioning air inlet or the temperature sensor detection close to the position of air-conditioning air inlet and acquisition EAT, make
For indoor temperature.When outdoor temperature refers to that air conditioner is started shooting and runs heating mode, case setting obtained in real time using frequency
Environment temperature residing for air conditioner outside room.The acquisition of the outdoor temperature can be realized using prior art, for example, by setting
The temperature sensor on air-conditioner outdoor unit is put to detect and obtain.
Then, indoor temperature and outdoor temperature are made comparisons with the first inside temperature thresholds and outdoor temperature threshold value respectively.
Wherein, the first inside temperature thresholds and outdoor temperature threshold value, as whether the threshold temperature of fuzzy control is performed, can be air-conditionings
A preset default temperature value in a control program or a temperature by air conditioner user's sets itself when device dispatches from the factory
Angle value.If by user's sets itself, preferably air conditioner recommends a reference temperature value, for reference.It is preferred that, it is preset
The first inside temperature thresholds or the first inside temperature thresholds of recommendation be 20 DEG C, preset outdoor temperature threshold value or the room of recommendation
Outer temperature threshold is 14 DEG C.
Step 22：Judge whether that meeting indoor temperature is not more than the first inside temperature thresholds and outdoor temperature no more than room
Outer temperature threshold.If so, performing step 23；Otherwise, step 26 is gone to.
Step 23：Perform fuzzy control.
If step 22 judges that indoor temperature is not more than the first inside temperature thresholds and outdoor temperature no more than outdoor temperature
Threshold value, then perform fuzzy control process.The detailed process and method of fuzzy control refer to the description of Fig. 1 embodiments.
Step 24：Indoor temperature is obtained, indoor temperature is made comparisons with the second inside temperature thresholds.
Specifically, during fuzzy control is performed, indoor temperature is still obtained in real time, and by acquired Indoor Temperature
Degree is made comparisons with the second inside temperature thresholds.Wherein, whether the second inside temperature thresholds are as exiting the threshold value temperature of fuzzy control
Degree, it is similar with the first inside temperature thresholds, the second inside temperature thresholds be also when air conditioner dispatches from the factory it is preset in a control program
A default temperature value or a temperature value by air conditioner user's sets itself.If voluntarily being set by user
Fixed, preferably air conditioner recommends a reference temperature value, for reference.It is preferred that, preset the second inside temperature thresholds or push away
The second inside temperature thresholds recommended are 25 DEG C.
Step 25：Judge whether indoor temperature is more than the second inside temperature thresholds.If so, going to step 26；Otherwise, go to
Step 23.
If indoor temperature is not more than the second inside temperature thresholds, step 23 is gone to, fuzzy control is continued executing with.And such as
Fruit indoor temperature is more than the second inside temperature thresholds, then to exit fuzzy control, go to the control of step 26, it is therefore an objective to indoors
Temperature reached after the second more suitable indoor temperature, no longer forces high frequency operation, it is to avoid compressor Yin Dawen and shut down.
Step 26：Perform room temperature PID control.
The step selects to perform according to the judged result of step 22 or step 25.Specifically, if judged in step 22
Indoor temperature before fuzzy control is entered is more than the first inside temperature thresholds or outdoor temperature is more than outdoor temperature threshold value,
Fuzzy control is not performed then, but performs room temperature PID control.If that is, indoor temperature be more than the first inside temperature thresholds or
Person's outdoor temperature is more than outdoor temperature threshold value, and it is not relatively low to show indoor temperature, or outdoor temperature is not relatively low, this situation
Under, do not consider coil temperature, and conventional room temperature PID control is used, calculate between indoor temperature and setting indoor target temperature
The temperature difference, obtain the indoor temperature difference, room temperature PID computing carried out according to the indoor temperature difference, obtain first object frequency, by first object frequency
Rate is as indoor unit frequency, according to the compressor of indoor set FREQUENCY CONTROL air conditioner.If judging fuzzy in execution in step 25
Indoor temperature in control process is more than the second inside temperature thresholds, will move out fuzzy control, and is transferred to room temperature PID and controlled
Journey.If that is, indoor temperature has been more than the second inside temperature thresholds in fuzzy control process, no matter now outdoor temperature
Just, to avoid, up to temperature shutdown, not considering further that coil temperature, and conventional room temperature PID control is used, calculates indoor temperature with setting
Determine the temperature difference between indoor target temperature, obtain the indoor temperature difference, room temperature PID computing is carried out according to the indoor temperature difference, obtain the first mesh
Frequency is marked, using first object frequency as indoor unit frequency, according to the compressor of indoor set FREQUENCY CONTROL air conditioner.
The other technologies effect of air conditioner heat-production control is performed using Fig. 2 embodiments, retouching for Fig. 1 embodiments is referred to
State.
In the fuzzy control process of the various embodiments described above, the second target frequency can be determined using various ways.
In some preferred embodiments, the second target frequency can be determined using following manner：
Whether after coil temperature is got, it is to be not more than setting coil pipe after air conditioner is started shooting first to first determine whether coil temperature
Target temperature, and according to the different processing of judged result execution.Specifically, if coil temperature is not more than first after starting shooting
Coil pipe target temperature is set, is to lift coil temperature as early as possible, the peak frequency that heats of setting is defined as the second target frequency.Its
In, heat peak frequency of the peak frequency for the setting in air conditioner heat-production running.And if after coil temperature is start
It is non-to be not more than setting coil pipe target temperature first, then compressor current operation frequency is raised, obtained between current operation frequency
And heat the second target frequency between peak frequency.If coil temperature is non-to be not more than setting coil pipe target temperature, table first
Bright to have performed fuzzy control, then coil temperature will not be less than very much coil pipe target temperature, in this case, the second target frequency is not
Necessity is increased to heat peak frequency, but between current operation frequency and heats frequency values between peak frequency i.e.
Can, it is to avoid cause because frequency is excessive up to temperature shutdown.
If also, coil temperature air conditioner start after it is non-first be not more than setting coil pipe target temperature, obtain compression
The current operation frequency of machine, every setting adjustment time by current operation frequency raise setting adjustment frequency, after rise
Frequency is defined as the second target frequency.Moreover, every time using current operation frequency rise adjustment frequency as after the second target frequency,
First judge the difference for setting coil pipe target temperature and coil temperature whether not less than the overshoot temperature value set；If so, in adjustment
Time continues executing with the process for raising current operation frequency and adjusting frequency as the second target frequency after reaching, and otherwise, keeps
Second target frequency is constant.
Specifically, ought if coil temperature is not more than setting coil pipe target temperature first to be non-after air conditioner start
The adjustment frequency of preceding running frequency rise setting, the frequency after rise is defined as the second target frequency.Wherein, the adjustment frequency of setting
Rate is a frequency values pre-set before air-conditioning dispatches from the factory, or is a frequency values of user's sets itself, for example, setting
For 5Hz.The frequency values represent the elevation amplitude every time to current operation frequency as a frequency adjusting step.Moreover, to frequency
The reduction of rate is using by the way of setting adjustment time reduction once, and realization is progressively adjusted, and the frequency after raising is used as the
Two target frequencies.After current operation frequency rise adjustment frequency, first judge setting coil pipe target temperature and coil temperature it
Whether difference is more than overshoot temperature value.Wherein, overshoot temperature value is also the temperature value of a setting, for example, being set as 1 DEG C.If
Judge that the difference of setting coil pipe target temperature and coil temperature is more than overshoot temperature value, show coil temperature far below setting coil pipe mesh
Mark temperature, it is still necessary to further raising frequency.Moreover, as it was previously stated, raising frequency processing procedure raises one for the adjustment time of interval setting
It is secondary.Adjustment time is also a pre-set value, represents the interval time of frequency adjustment.For example, can be set as 2min.
That is, after adjustment once, first using the frequency after adjusting as the second target frequency, when adjustment time is not up to, keeping
Second target frequency is constant, until exiting fuzzy control and entering room temperature PID control or shutdown or adjustment time arrival.Adjusting
After the whole time reaches, then compressor current operation frequency is read, based on current operation frequency, continue to enter according to adjustment frequency
Row raising frequency.
If it is determined that and the difference for setting coil pipe target temperature and coil temperature is not more than overshoot temperature value, showing coil temperature
Though do not reach setting coil pipe target temperature also, and the difference of setting coil pipe target temperature is smaller, no more than overshoot temperature value.This
When, then subsequently no longer raise frequency.Thus, keep the second target frequency determined constant, until exiting fuzzy control and entering
To room temperature PID control or shutdown.
