It opens and should not be limited by the embodiments set forth herein.It is to be able to thoroughly understand this on the contrary, providing these embodiments
It is open, and the scope of the present disclosure can be fully disclosed to those skilled in the art.
Below with reference to the accompanying drawings it is filled to describe the control of the control method, air-conditioning of the air-conditioning proposed according to the embodiment of the present application
It sets, air-conditioning, electronic equipment and non-transitorycomputer readable storage medium.
Fig. 1 is the flow chart according to the control method of the air-conditioning of the embodiment of the present application.As shown in Figure 1, the embodiment of the present application
The control method of air-conditioning may include following steps：
S1 obtains the return air temperature and leaving air temp of indoor unit when air-conditioning is run under mode of rising again automatically.
Specifically, the automatic mode of rising again of air-conditioning refers to, during air conditioner refrigerating operation, when room temperature is lower than
When a certain temperature value, automatically air-conditioning is adjusted correspondingly so that room temperature is gone up.In practical applications, user Ke Tong
Remote controler or mobile terminal (for example, mobile phone etc.) selection " rising again automatically " function are crossed, so that air-conditioning is risen again under mode automatically
Operation.
When air-conditioning rise again automatically run under mode when, can be by the way that the temperature sensing of the return air inlet of air conditioner indoor unit be arranged in
The return air temperature Th of device detection indoor unit, wherein the return air temperature Th of indoor unit is close in room temperature；And it can be by setting
Set the leaving air temp Tc in the temperature sensor detection indoor unit of the air outlet of air conditioner indoor unit, wherein run in air conditioner refrigerating
During, in order to make the temperature detected closer to air outlet of indoor set minimum temperature, temperature sensor can be arranged
The bottom of air outlet of indoor set, the temperature value which detects can reflect the leaving air temp of indoor unit, i.e. room
Air temperature value of the interior air after heat exchanger exchanges heat.Under normal circumstances, when the air conditioner is in refrigeration operation, the wind-warm syndrome out of indoor unit
Spend the return air temperature Th that Tc is less than indoor unit.
S2, according to the return air temperature and leaving air temp of indoor unit, the return air temperature that control reduces indoor unit is less than or waits
In set temperature.
In practical applications, when air conditioner refrigerating is run, in the identical situation of air conditioning exhausting amount, if leaving air temp Tc
And the deviation of return air temperature Th is larger, then illustrates that the deviation of room temperature (that is, return air temperature Th) and set temperature is larger, indoor
The fast speed of temperature decline.Therefore, air-conditioning can be carried out according to the return air temperature Th and leaving air temp Tc of indoor unit corresponding
Adjustment, so that the return air temperature Th of indoor unit is decreased below or is equal to set temperature Ts, i.e. room temperature decreases below
Or it is equal to set temperature Ts, to meet the needs of users.
S3 continues to obtain return air temperature and leaving air temp.
In practical applications, after the return air temperature that control reduces indoor unit is less than or equal to set temperature Ts, human body
Surface temperature is gradually lowered.If user is in indoor low temperature environment for a long time, it is easy the temperature mistake so that body surface
It is low, to generate creeping chill.Therefore, after the return air temperature Th that control reduces indoor unit is less than or equal to set temperature Ts, also
It needs to continue to obtain return air temperature Th and leaving air temp Tc, to continue to carry out air-conditioning according to return air temperature Th and leaving air temp Tc
Corresponding control.
S4, if the temperature difference continued between the return air temperature got and leaving air temp is in preset first temperature range
It is interior, then the running frequency for reducing compressor is controlled, to increase within the scope of return air temperature to preset second temperature.
Wherein, preset first temperature range can be demarcated according to the actual situation, for example, the first temperature range can be 2
~10 DEG C；The lower limit value of preset second temperature range can be set temperature Ts, upper limit value can for temperature threshold Ts with it is a certain solid
Determine temperature value and value, for example, second temperature range can be Ts~Ts+3.
Specifically, air-conditioning, and can not be right only by the setting temperature sensor at the return air inlet of machine indoors at present
Air-conditioning is accurately controlled, and comfortable environment temperature can not be accurately provided the user with.Also, in the mistake of air conditioner refrigerating operation
Room temperature is usually rapidly reduced to set temperature, and room temperature is maintained within the scope of certain temperature by Cheng Zhong
Continuous service, to realize the effect of refrigeration.However, during air conditioner refrigerating operation, if at room temperature long-time
In a lower temperature, then human surface temperature gradually decreases and is easy to produce creeping chill, greatly affected the comfortable of user
Experience.
Therefore, in the embodiment of the present application, rise again automatically mode, and the return air inlet of machine and outlet air indoors are set in air-conditioning
Temperature sensor is respectively set in mouth, to detect the return air temperature Th and leaving air temp Tc of indoor unit respectively, and according to indoor unit
Return air temperature Th and leaving air temp Tc air-conditioning is accurately controlled.
It specifically, can be by the way that the return air inlet of machine and outlet air indoors be arranged when air-conditioning is run under mode of rising again automatically
Temperature sensor at mouthful detects the return air temperature Th and leaving air temp Tc of indoor unit respectively, and according to the return air temperature of indoor unit
Degree Th and leaving air temp Tc is adjusted correspondingly air-conditioning, is less than or equal to controlling the return air temperature Th of reduction indoor unit
Set temperature Ts, i.e. control reduce room temperature and are less than or equal to set temperature Ts, to achieve the effect that fast cooling, meet
The demand of user.When the return air temperature Th of control control indoor unit is less than or equal to set temperature Ts, it is also necessary to pass through temperature
Degree sensor continues to test return air temperature Th and leaving air temp Tc.If at the temperature difference between return air temperature Th and leaving air temp Tc
In in preset first temperature range, then illustrate that the deviation between room temperature and set temperature is smaller, room temperature, which meets, to be used
The demand at family, at this point, in order to avoid user because long-time is in the low temperature environment cause shell temperature it is too low cause it is cold
Sense can control the running frequency for reducing compressor, to increase within the scope of return air temperature Th to preset second temperature, so that
Room temperature gos up certain temperature (for example, ging up 1~3 DEG C).
As a result, air conditioner refrigerating run during, when air-conditioning with rise again automatically mode operation when, by be arranged indoors
The return air temperature and leaving air temp that two kinds of temperature sensors at machine air outlet and return air inlet detect carry out air-conditioning corresponding
Control, can accurately and effectively control the temperature that room temperature first decreases below setting, to meet the needs of users, and tie up
After holding a period of time, so that room temperature is gone up certain temperature (for example, ging up 1~3 DEG C), avoid because of human body table
Face temperature is too low and generates creeping chill, to substantially increase the Experience Degree of user.
It should be noted that can also adjust the return air of indoor unit by other means in the other embodiments of the application
Temperature Th, for example, be adjusted correspondingly by adjusting the air output of air-conditioning with the return air temperature Th to indoor unit, specifically,
It can refer to the return air temperature Th of aforesaid way adjustment indoor unit, details are not described herein.
Based on the above embodiment, in order to timely and accurately the return air temperature Th of indoor unit is decreased below or is waited
In set temperature Ts, the embodiment of the present application proposes a kind of return air temperature Th and leaving air temp Tc according to indoor unit, control drop
The return air temperature Th of low indoor unit is less than or equal to the method for set temperature Ts, as shown in Fig. 2, this method may include following step
Suddenly：
S201, control compressor are run under the first running frequency.
When air-conditioning, which enters, rises again mode automatically, controllable compressor is run under the first running frequency, to reduce interior
Temperature realizes the effect of refrigeration.Wherein, the first running frequency can be demarcated according to the actual situation.
S202, if the temperature difference between return air temperature and leaving air temp is greater than preset first numerical value, control increases compression
The running frequency of machine, to reduce return air temperature less than or equal to preset temperature.
Wherein, preset first numerical value can be the upper limit value of preset first temperature range of the first temperature, for example, preset
First numerical value can be 10 DEG C.
If the temperature difference between return air temperature Th and leaving air temp Tc is greater than preset first numerical value, room temperature and set
The deviation for determining temperature Ts is larger, therefore, can control the running frequency for increasing compressor, promotes the speed of room temperature decline, make
Obtaining return air temperature Th can be rapidly reduced to be less than or equal to preset temperature Ts, i.e., so that room temperature can rapidly reach use
The demand at family.
Further, control increases the frequency of compressor, to reduce return air temperature less than or equal to set temperature, can wrap
It includes：The return air temperature for continuing to obtain is compared with set temperature, if return air temperature is greater than set temperature, controls continuation
The running frequency for increasing compressor reaches maximum frequency of operation, and controls and run under maximum frequency of operation, until return air temperature
Less than or equal to set temperature.
Specifically, when the air conditioner is in refrigeration operation, during controlling room temperature quickly reduces, can be existed by setting
The temperature sensor of indoor unit return air inlet continues to test the return air temperature Th of indoor unit, and by return air temperature Th and set temperature Ts
It is compared, if return air temperature Th is still greater than set temperature Ts, the running frequency that control continues to increase compressor is reached
Maximum frequency of operation, so that air-conditioning is run under maximum frequency of operation, so that room temperature is rapidly reduced to the full extent,
To meet the needs of users.Wherein, the maximum frequency of operation (for example, 65Hz) of compressor is in combination with factors such as outdoor environment temperatures
It is demarcated, the running frequency of compressor is farthest increased, to be promoted in the case where ensuring that air-conditioning operates normally
The working efficiency of air-conditioning.
It should be noted that in practical applications, when air-conditioning, which enters, rises again mode automatically, raising pressure can also be directly controlled
The running frequency of contracting machine is maximum frequency of operation, rapidly reduces room temperature to the full extent, to meet the needs of users,
Meanwhile promoting the working efficiency of air-conditioning.
According to one embodiment of the application, if the temperature difference between the return air temperature and leaving air temp that get is lower than the
The lower limit value of one temperature range, then control continues to reduce the running frequency of compressor.
Specifically, if the temperature difference between return air temperature Th and leaving air temp Tc is not in the first temperature range, and it is low
When the lower limit value of the first temperature range, illustrate that the deviation of return air temperature Th and leaving air temp Tc are smaller at this time, room temperature connects
It is bordering on set temperature Ts, in order to avoid user causes the too low generation of shell temperature cold because long-time is in low temperature environment
Sense, at this point, the controllable running frequency for continuing to reduce compressor, to increase return air temperature Th to preset second temperature range
It is interior, i.e., within the scope of raising room temperature to second temperature.
Further, after the running frequency of control reduction compressor is to increase room temperature, in order to ensure return air temperature
Degree maintains within the scope of preset second temperature, i.e., room temperature maintains in human comfort's temperature range, and one of the application
Embodiment also proposed a kind of control method of the running frequency of compressor, as shown in figure 3, this method may include following steps：
S301 controls air-conditioning with the running frequency after reducing and runs preset duration.
Specifically, can control the running frequency for increasing compressor to reach maximum fortune during air conditioner refrigerating operation
Line frequency (for example, 65Hz), and control air-conditioning and run under the maximum frequency of operation, until return air temperature Th is less than or equal to
Set temperature Ts, i.e. room temperature are met the needs of users.When temperature is met the needs of users indoors, in order to avoid user because
Lead to that shell temperature is too low to cause creeping chill in the low temperature environment for a long time, can control the running frequency for reducing compressor
Room temperature is increased, and according to the operation after reduction to the second running frequency (for example, 52Hz) to increase return air temperature Th
Frequency runs preset duration (preset duration can be demarcated according to the actual situation, for example, 5 minutes).Wherein, maximum frequency of operation
Greater than the second running frequency.
S302 continues to obtain return air temperature, if continuing the return air temperature got is in preset second temperature range
It is interior, then it controls and maintains the running frequency after reducing.
After control air-conditioning is with the running frequency operation preset duration after reducing, also need to continue to obtain return air temperature Th, with
Judge whether the running frequency for needing to continue to reduce compressor according to return air temperature Th, that is, judges whether current indoor temperature is in
In human comfort's temperature range.If continuing the return air temperature Th got is in preset second temperature range (for example, being in
Ts~Ts+3) in, then illustrate that room temperature is in human comfort's temperature range at this time, therefore, can control after maintaining to reduce
Running frequency provides the user with comfortable environment temperature so that room temperature maintains in human comfort's temperature range.
S303, if the return air temperature for continuing to get is not within the scope of second temperature, continuing control reduces compression
The running frequency of machine.
If continuing the return air temperature got to be in preset second temperature range (for example, being in Ts~Ts+3),
Then illustrate that room temperature is still lower at this time, is easy to be unable to satisfy user's so that human surface temperature is too low and generates creeping chill
Demand therefore, it is necessary to continue control to reduce the running frequency of compressor to third running frequency (for example, 30Hz), and is returned and is held
Row step S301, at this point, control air-conditioning runs preset duration with the running frequency (that is, third running frequency) after reducing, so
Circulation to gradually rise return air temperature Th, that is, increases room temperature by gradually decreasing the running frequency of compressor, until returning
Air temperature Th is within the scope of preset second temperature, i.e., room temperature is in human comfort's temperature range, to mention to user
For comfortable environment temperature.Wherein, third running frequency is less than the second running frequency.
Further, after increasing within the scope of return air temperature to preset second temperature, further include：By adjusting air-conditioning
The running frequency of middle compressor and/or the air output of air-conditioning, control return air temperature maintain within the scope of second temperature.
Specifically, may be used also after increasing within the scope of return air temperature Th to preset second temperature through the above way
Air-conditioning is controlled accordingly, to ensure that return air temperature Th can be accurately maintained within the scope of second temperature, that is, ensures room
Interior temperature is able to maintain that in human comfort's temperature range, to provide the user with comfortable environment temperature.
Wherein, return air temperature Th can be controlled, i.e., by adjusting the running frequency of compressor in air-conditioning to Indoor Temperature
Degree is controlled.When the air conditioner is in refrigeration operation, the running frequency of compressor is higher, and return air temperature Th is lower, i.e. room temperature
It is lower.
Alternatively, air-conditioning can be carried out to return air temperature Th by adjusting the air output of air-conditioning.When the air conditioner is in refrigeration operation, empty
The air output of tune is bigger, and return air temperature Th is lower, i.e., room temperature is lower.
Alternatively, can be carried out by adjusting the running frequency of compressor in air-conditioning and the air output of air-conditioning to return air temperature Th
Corresponding control.
As a result, as shown in figure 4, by " rising again automatically " function, when the air conditioner is in refrigeration operation, reduced in control room temperature
To less than or after being equal to preset set temperature Ts (that is, control return air temperature Th be less than or equal to set temperature Ts), can
Accurately and effectively (that is, control return air temperature Th is higher than set temperature in control room in temperature recovery to human comfort's temperature range
Ts), and (for example, maintaining in Ts~Ts+3) is maintained in human comfort's temperature range.
In conclusion being run under mode of rising again automatically according to the control method of the air-conditioning of the embodiment of the present application in air-conditioning
When, the return air temperature and leaving air temp of indoor unit are obtained, and according to the return air temperature and leaving air temp of indoor unit, control reduces room
The return air temperature of interior machine is less than or equal to set temperature, and continues to obtain return air temperature and leaving air temp, and continuing to obtain
When the temperature difference between return air temperature and leaving air temp got is in preset first temperature range, control reduces compressor
Running frequency, to increase within the scope of return air temperature to preset second temperature.As a result, during air conditioner refrigerating is run, when
Air-conditioning with rise again automatically mode operation when, detected according to two kinds of temperature sensors at setting indoors machine air outlet and return air inlet
To return air temperature and leaving air temp air-conditioning is controlled accordingly, can accurately and effectively control room temperature and first be reduced to
Lower than the temperature of setting, to meet the needs of users, and after maintaining a period of time, accurately and effectively make room temperature rise one
Fixed temperature avoids generating creeping chill because human surface temperature is too low, to substantially increase the Experience Degree of user.
Fig. 5 is the block diagram according to the control device of the air-conditioning of the embodiment of the present application.As shown in figure 5, the application is real
