Detailed description of the invention
Fig. 1 is the flow chart of air conditioning control method one embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to drawings and examples,
Invention is further described in detail.
Referring to Figure 1, which show the flow chart of air conditioning control method one embodiment of the present invention.
As shown in Figure 1, the method that the embodiment realizes airconditioning control includes the following steps:
Step 11: operation of air conditioner, the real-time indoor detection temperature in room where constantly obtaining air-conditioning according to the setting sampling period
Degree.
For wall-hanging air conditioner, in general, the air inlet in air-conditioning is provided with temperature sensor, the temperature sensor energy
Enough temperature that air inlet is constantly exported according to the setting sampling period, and the temperature reflects the temperature of air inlet.Air-conditioning master control borad
On controller connect with temperature sensor, temperature sensor temperature signal detected can be got, and the temperature is made
For real-time indoor detection temperature.Moreover, controller will record the indoor detection temperature at least two sampling periods, to carry out
The calculating of rate of temperature change.
Step 12: calculating the change rate of indoor detection temperature in real time.
The change rate of interior detection temperature preferably but not limited to uses following methods to calculate in real time:
Obtained the upper period collected in a upper sampling period in the sampling period locating for real-time indoor detection temperature
Indoor detection temperature calculates the change rate of indoor detection temperature in real time according to following formula:
The change rate of interior detection temperature=(detecting temperature in interior detection temperature-room of upper period in real time)/sampling week in real time
Phase.
For example, the sampling period of temperature sensor is t, and the real-time sampling period is n-th of period, corresponding real-time room
Interior detection temperature is Tn；So, a upper sampling period is (n-1) a period, and detection temperature is T in corresponding room of upper period
(n-1).So, change rate=[Tn- T (n-1)]/t of real-time indoor detection temperature.
Step 13: according to the size relation of the absolute value of the change rate of real-time indoor detection temperature and setting change rate threshold value
And real-time indoor detection temperature selects different compensation temperatures from the size relation of setting target temperature, according to compensation temperature pair
Interior detection temperature compensates in real time, forms real-time indoor environment temperature, according to real-time indoor environment temperature and setting target temperature
The temperature difference between degree carries out PID arithmetic, obtains compressor target frequency and controls the compressor of air-conditioning.
Wherein, setting change rate threshold value be the numerical value that is stored in advance, can call at any time, be air-conditioning factory before, by
Air-conditioning research staff is obtained by special experiment condition and the test of special test means and is written to the memory of air-conditioning master control borad
In numerical value.The value can be fixed value, be also possible to variable value.
Compensation temperature is also the temperature value for being stored in advance, can obtaining and call at any time, is ground before air-conditioning factory, by air-conditioning
Hair personnel are obtained by special experiment condition and the test of special test means and are written in the memory of air-conditioning master control borad.And
And compensation temperature be it is multiple, be not only stored with specific compensation temperature value in memory, be also stored with some compensation temperature value
Specific choice condition.Specific compensation temperature value, alternative condition and selection mode can refer to subsequent description.
The case where size of the change rate of interior detection temperature reflects indoor detection temperature change speed in real time, change rate
Absolute value it is bigger, show that indoor detection temperature change is faster；, whereas if the absolute value of change rate is smaller, show indoor inspection
Testing temperature variation is smaller.
For example, change rate is positive number, and absolute value is larger, shows that indoor detection temperature is in rapid increase at this time.Indoor inspection
Testing temperature may be using scene in rapid increase, corresponding air-conditioning: winter makes outdoor environment temperature is lower, indoor environment temperature
It is very low；It during user goes back home, closes the doors and windows, opens air-conditioning, run heating mode；Under the heating effect of air-conditioning, indoor environment
Temperature quickly increases.It is also possible to use scene are as follows: in summer, operation of air conditioner refrigeration mode, indoor detection temperature is with air-conditioning
Long-time refrigerating operaton has had arrived at relatively low temperature；But at a time, make room temperature anxious for some reason
Play rises.In this case, for make room temperature fast approaching set target temperature, it is desirable to air-conditioning operates in a high frequency, with fast
Speed improves the comfort of room temperature.
And change rate is negative, and absolute value is larger, shows that indoor detection temperature drops at the fast speed at this time.Indoor detection temperature
Rapid decrease is spent, corresponding air-conditioning may be using scene: in summer, under the baking of the sun, indoor environment temperature has reached one
Definite value；It during user goes back home, closes the doors and windows, opens air-conditioning, run refrigeration mode；Under the refrigeration of air-conditioning, indoor environment
Temperature quickly reduces.It is also possible to use scene are as follows: in winter, operation of air conditioner heating mode, indoor detection temperature is with air-conditioning
Long-time refrigerating operaton has had arrived at relatively high temperature；But at a time, for some reason, for example door and window is all beaten
It opens, cold air is come in, so that room temperature sharply declines.In this case, for make room temperature fast approaching set mesh
Mark temperature, it is desirable to which air-conditioning operates in a high frequency, quickly to improve the comfort of room temperature.
If change rate absolute value is smaller, show that indoor detection temperature change is little at this time.Indoor detection temperature change is little,
Corresponding air-conditioning may be using scene: indoor through operation after a period of time after summer opens operation of air conditioner refrigeration mode
Temperature is already close to setting target temperature；Alternatively, after winter opens operation of air conditioner heating mode, through fortune after a period of time
Row, the close setting target temperature of room temperature.In this case, to avoid the occurrence of temperature overshoot, while going out from Energy Angle
Hair can control the operating of air-conditioning low frequency.It is also possible to use scene are as follows: in the public area that closure is poor, air flow property is big
Domain, although air-conditioner continuous refrigeration or heating operation, since airtightness is inadequate, indoor detection temperature there is no significant decline or
Rise, the temperature difference between setting target temperature is still very big.For this situation, for the comfort for improving room temperature, it is desirable to empty
Tune operates in a high frequency.
In addition, since the installation site of wall-hanging air conditioner in the room is relatively high, the temperature sensor of air inlet
Interior detection temperature detected and indoor actual ambient temperature there is also certain temperature difference, concrete reason and show themselves in that for
Wall-hanging air conditioner, installation site is relatively high in the room, is generally all mounted on apart from the position on 2 meters or so of ground.Thus, it is empty
The temperature sensor air themperature detected for adjusting air inlet to be arranged is the temperature of the air at the height of 2 meters or so of ground
Degree.And in the room, user's main activities Spatial General 6 R is from ground to the area of space apart from 1.35 meters or so of ground.According to
The theory of molecular motion, hot-air move upwards, and cold air moves downward.So, in operation of air conditioner heating mode, due to hot-air
Rise, therefore, the temperature drift of the temperature of upper air than lower air；And in operation of air conditioner refrigeration mode, due to cold
Air sinks, and the temperature of upper air is also than the temperature drift of lower air.To detected by indoor temperature transmitter
Indoor detection temperature drift is in the temperature in user's main activities space, that is, indoor detection temperature is higher than average indoor ring
Border temperature.Therefore, it if a temperature using indoor detection temperature as PID control, controls not accurate enough.
The size of change rate based on above-mentioned indoor detection temperature and in real time indoor detection temperature and setting target temperature
The different air-conditioning usage scenarios that are reflected of size relation, and to the demand of airconditioning control under different usage scenarios,
Simultaneously, it is also contemplated that the difference of indoor detection temperature acquired in wall-hanging air conditioner and indoor actual ambient temperature, it will be for not
Same situation selects different compensation temperatures to compensate real-time indoor detection temperature, forms real-time indoor environment temperature, then,
PID arithmetic is carried out according to the temperature difference between compensated real-time indoor environment temperature and setting target temperature, obtains compressor mesh
Mark frequency and the compressor for controlling air-conditioning.To which temperature different shapes can be in indoors by reasonably selecting compensation temperature
Reasonable compressor frequency control can be carried out under state so that when indoor environment temperature pace of change is very fast or with setting target
It can control compressor when temperature difference is larger to operate with upper frequency, so that room temperature is quickly leaned on to indoor target temperature
Closely；And when indoor environment temperature pace of change slowly or with setting target temperature difference it is smaller when can control compressor with lower
Frequency run, so that the actual temperature in user's main activities space is relaxed closer to setting target temperature improving room temperature
Energy consumption of compressor can also be reduced while adaptive, realize energy saving.
In the above-described embodiments, how to select reasonably to supplement temperature, be concerning airconditioning control comfort and energy saving
Key factor.
As preferred embodiment, step 13 specifically can be compensated and be obtained using following methods selection compensation temperature
Obtain compressor target frequency:
If the absolute value of the change rate of interior detection temperature is greater than setting change rate threshold value in real time, the first compensation temperature is selected
It spends, calculates the temperature of indoor detection temperature in real time and the first compensation temperature and and as the first indoor environment temperature, calculating first
The temperature difference between indoor environment temperature and setting target temperature, according between the first indoor environment temperature and setting target temperature
The temperature difference carries out PID arithmetic, obtains compressor target frequency and controls the compressor of air-conditioning.Wherein, the selection of the first compensation temperature,
The temperature difference for making the first indoor environment temperature and setting between target temperature is greater than indoor detection temperature in real time and setting target
The temperature difference between temperature.
If the absolute value of the change rate of interior detection temperature is no more than setting change rate threshold value in real time, then judges real-time interior
Whether detection temperature and the temperature difference set between target temperature are greater than the setting temperature difference；
If the temperature difference between interior detection temperature and setting target temperature is greater than the setting temperature difference in real time, the second compensation temperature is selected
It spends, calculates the temperature of indoor detection temperature in real time and the second compensation temperature and and as the second indoor environment temperature, calculating second
The temperature difference between indoor environment temperature and setting target temperature, according between the second indoor environment temperature and setting target temperature
The temperature difference carries out PID arithmetic, obtains compressor target frequency and controls the compressor of air-conditioning；The selection of second compensation temperature, so that
The temperature difference between second indoor environment temperature and setting target temperature be greater than indoor detection temperature in real time and setting target temperature it
Between the temperature difference；
If the temperature difference between interior detection temperature and setting target temperature calculates the interior no more than the setting temperature difference in real time
It detects the temperature difference of temperature and third compensation temperature and as third indoor environment temperature, calculates third indoor environment temperature and set
The temperature difference between the temperature that sets the goal carries out PID arithmetic according to the temperature difference between third indoor environment temperature and setting target temperature,
It obtains compressor target frequency and controls the compressor of air-conditioning；Third compensation temperature is positive number.
Specifically, if air-conditioning real time execution mode is refrigeration mode, the first compensation temperature is positive number.This be because
For if the absolute value of the change rate of indoor detection temperature is greater than setting change rate threshold value, and the change rate of indoor detection temperature is
It is negative, show that room temperature declines under the action of refrigeration mode, then real-time indoor detection temperature at this time is higher than setting target temperature
Degree.So, one is used to be added the obtained first indoor ring for the first compensation temperature of positive number with real-time indoor detection temperature
Border temperature is higher than indoor detection temperature in real time and setting target temperature, carries out the temperature difference used in PID arithmetic to increase
Value, and then higher compressor frequency can be obtained by PID arithmetic, control air-conditioning high frequency operation, enable temperature more
Rapidly approach setting target temperature.
Likewise, if air-conditioning real time execution mode is refrigeration mode, if the absolute value of the change rate of indoor detection temperature
Change rate greater than setting change rate threshold value, and indoor detection temperature is positive, show at this time room temperature in cooling mode, by
Lead to room temperature rapid increase in certain reason, refrigeration effect needed for user cannot be reached.At this point, by using positive number
First compensation temperature compensates indoor environment temperature, and higher compressor frequency can be obtained by PID arithmetic, controls air-conditioning
High frequency operation, enables temperature to approach setting target temperature more quickly.
And if air-conditioning real time execution mode is heating mode, the first compensation temperature is negative.Specifically, if air-conditioning
In heating operation, if the absolute value of the change rate of indoor detection temperature is greater than setting change rate threshold value, and indoor detection temperature
Change rate be positive, show room temperature rapid increase under the action of heating mode, then indoor detection temperature at this time is lower than
Set target temperature.So, use one be added for the first compensation temperature of negative with real-time indoor detection temperature it is obtained
First indoor environment temperature will be lower than in real-time indoor detection temperature and setting target temperature, to increase carry out PID arithmetic
The value of the used temperature difference, and then higher compressor frequency can be obtained by PID arithmetic, control air-conditioning high frequency operation makes
Setting target temperature can be approached more quickly by obtaining temperature.
Likewise, if air-conditioning real time execution mode is heating mode, if the absolute value of the change rate of indoor detection temperature
Change rate greater than setting change rate threshold value, and indoor detection temperature is negative, show at this time room temperature in a heating mode, by
Lead to room temperature rapid decrease in certain reason, heating effect needed for user cannot be reached.At this point, by using negative
First compensation temperature compensates indoor environment temperature, increases the value for carrying out the temperature difference used in PID arithmetic, can pass through
PID arithmetic obtains higher compressor frequency, and control air-conditioning high frequency operation enables temperature to approach setting target more quickly
Temperature.
It is similar with the first compensation temperature for the second compensation temperature, if air-conditioning real time execution mode is refrigeration mode,
Second compensation temperature is positive number, if air-conditioning real time execution mode is heating mode, the second compensation temperature is negative.
For example, if air-conditioning real time execution mode is refrigeration mode, the change rate of interior detection temperature is exhausted in real time
To value no more than setting change rate threshold value, show that indoor detection temperature change is little.If real-time indoor detection temperature at this time
The temperature difference between setting target temperature has been greater than the preset setting temperature difference, shows that room temperature is higher always, it is difficult to will
To setting target temperature, e.g. in non-close, use environment that mobility is strong.In this case, use one for positive number
The second compensation temperature is added the second indoor environment temperature obtained with real-time indoor detection temperature and is higher than interior inspection in real time
Testing temperature and setting target temperature, to increase the value for carrying out the temperature difference used in PID arithmetic, and then can be transported by PID
Calculation obtains higher compressor frequency, and control air-conditioning high frequency operation enables temperature to approach to setting target temperature.Air-conditioning fortune
The second compensation temperature is that the principle of negative can refer to above description under row heating mode.
Moreover, embodiment more preferably, the first compensation temperature and the second compensation temperature are also not changeless,
But changed according to the difference of real-time indoor detection temperature.Specifically, the first compensation temperature is mended according to known first
It repays the corresponding relationship of temperature and indoor detection temperature and indoor detection temperature determines that the second compensation temperature is according to known in real time
The corresponding relationship of second compensation temperature and indoor detection temperature and in real time indoor detection temperature determine, and the first compensation temperature with
The corresponding relationship of the corresponding relationship of indoor detection temperature and the second compensation temperature and indoor detection temperature is negative correlativing relation.It lifts
For example, the corresponding relationship of the first compensation temperature and indoor detection temperature, an interior are previously stored in accumulator for air conditioner
Detection temperature corresponds to first compensation temperature, alternatively, the multiple indoor detection temperature for belonging to same temperature range correspond to
One the first compensation temperature.Moreover, indoor detection temperature is higher, corresponding first compensation temperature is lower, shows negative correlation
Relationship.When selecting the first compensation temperature, finds from corresponding relationship and mended with corresponding to indoor detection temperature in real time first
Repay temperature as real-time first compensation temperature come using.It is true by way of with real-time indoor detection temperature negative correlation
Fixed first compensation temperature or the second compensation temperature can further take into account temperature and adjust comfort and energy-saving property.Wherein,
The absolute value of one compensation temperature and the absolute value of the second compensation temperature are respectively less than 2 DEG C.
For third compensation temperature, be when indoor detection temperature in real time change rate no more than setting change rate threshold value and
The used compensation temperature when temperature difference between interior detection temperature and setting target temperature is no more than the setting temperature difference in real time.
In this case, room temperature relatively sets target temperature, it is necessary to consider the accuracy that room temperature is adjusted.
The starting point of control at this time is the difference of indoor detection temperature acquired in wall-hanging air conditioner and indoor actual ambient temperature.Cause
This, in this case, selecting perseverance is that the third compensation temperature of positive number makees temperature-compensating.
As previously indicated, in operation of air conditioner refrigeration mode, indoor temperature transmitter temperature detected, which is higher than, uses householder
Want the temperature of activity space.If still participating in PID arithmetic as room temperature according to the temperature that indoor temperature transmitter detects,
Indoor temperature difference when PID arithmetic is bigger than normal, and calculated compressor target frequency is higher, and control compressor is according to higher target frequency
Rate operation, causes air conditioning energy consumption bigger than normal.And if the real-time indoor detection temperature that first will test subtracts a positive third compensation temperature
Degree obtains the third indoor environment temperature for being less than indoor detection temperature in real time, and the third indoor environment temperature is more realistically anti-
The temperature in user's main activities space is reflected.When participating in PID arithmetic using the third indoor environment temperature less than normal, can obtain
Lesser compressor target frequency is obtained, is run using lesser target frequency control compressor, reduces energy consumption.Moreover, by
The temperature in user's main activities space is more realistically reflected in the third indoor environment temperature, thus, after also making adjusting
Room temperature be closer to setting target temperature, the problem of without overshoot, adjust comfort meeting temperature
Air conditioning energy consumption is reduced simultaneously.
Likewise, indoor temperature transmitter temperature detected is higher than user and mainly lives in operation of air conditioner heating mode
The temperature in dynamic space.If still participating in PID arithmetic, PID as room temperature according to the temperature that indoor temperature transmitter detects
Indoor temperature difference when operation is less than normal, and calculated compressor target frequency is relatively low, controls compressor according to relatively low target frequency
Operation, prevent room temperature from or need long-play to can be only achieved indoor target temperature, room temperature adjusts comfort
Difference, compressor long-play are also unfavorable for reducing energy consumption under a relatively not low target frequency.And if first will test
Room temperature subtracts a positive third compensation temperature, obtains the third indoor environment temperature for being less than indoor detection temperature in real time,
And the third indoor environment temperature more realistically reflects the temperature in user's main activities space.Utilizing the third room less than normal
When interior environment temperature participates in PID arithmetic, relatively larger compressor target frequency can be obtained, enables to room temperature fast
Speed reaches setting target temperature, improves the comfort that room temperature is adjusted.Moreover, because reaching the time contracting of setting target temperature
It is short, it is conducive to reduce energy consumption.
As preferred implementation method, third compensation temperature is determined using following methods:
The real time execution time for obtaining compressor after the real time execution frequency and air-conditioning booting of compressor, according to known the
The determination of the corresponding relationship of three compensation temperatures and press running frequency and press runing time and real time execution frequency and real time execution
Time corresponding third compensation temperature.Wherein, third compensation temperature and press running frequency and press runing time is corresponding
Relationship is stored in advance in accumulator for air conditioner, moreover, third compensation temperature and press running frequency are negative correlativing relation, third
Compensation temperature and press runing time are also negative correlativing relation.That is, press running frequency is bigger, third compensation temperature is bigger；
Press runing time is longer, and third compensation temperature is bigger.This is, because press running frequency is bigger or/and press runing time
Longer, interior detection temperature and the temperature difference in user's main activities space are bigger in real time, therefore, the third as compensation temperature
Compensation temperature is also bigger.
