Air-conditioner control method embodiment:
Air-conditioner control method is applied in air conditioner, after air conditioner, which starts, to be run, first with common mode operation,
Specifically, air conditioner is run according to step set in the prior art, such as air conditioner enters refrigeration mode, and according to current
Indoor temperature value and temperature value for setting determine the refrigerating capacity of air conditioner, and controlled according to the control signal received
Wind speed, wind direction, the blowing mode etc. of the blowout wind of indoor unit.
Referring to fig. 2, step S1 is first carried out in the method for the present embodiment, and air conditioner acquires indoor temperature value and outdoor temperature
Value.Specifically, being provided with a wind pushing temperature sensor and a return air temperature sensor on the indoor unit of the air conditioner, send
Air temperature sensor is used to detect the temperature of the indoor unit blowout wind of air conditioner, and return air temperature sensor is for detecting indoor unit
Return air temperature.In the present embodiment, the indoor temperature value of acquisition is return air temperature sensor temperature collected.Also, in outdoor
It is also equipped with a return air temperature sensor on machine, for acquiring the temperature value of outdoor environment, and uses the return air of outdoor unit
The temperature of temperature sensor acquisition is as outdoor temp angle value.
Then, step S2 is executed, judges that indoor temperature value whether less than the first preset temperature value, and judges outdoor temperature
Whether value is less than the second preset temperature value.In the present embodiment, the first preset temperature value and second is written on a memory in advance
Preset temperature value, it is preferred that the first preset temperature value can be set as 28 DEG C, and the second preset temperature value can be set as 38
℃.In step S2, indoor temperature value and preset first preset temperature value that step S1 is acquired are compared, judge room
Whether interior temperature value is less than the first preset temperature value.It is also desirable to by the outdoor temp angle value of acquisition and the second preset temperature value
It compares, judges outdoor temp angle value whether less than the second preset temperature value.
If indoor temperature value is less than the first preset temperature value, and outdoor temp angle value is again smaller than the second preset temperature value,
Then the judging result of step S2 is yes, executes step S3.If indoor temperature value is not less than the first preset temperature value or second
Outdoor temp angle value is not less than the second preset temperature value, then the judging result of step S2 is no, thens follow the steps S4.
If the judging result of step S2 be it is yes, then follow the steps S3, air conditioner enters preset mode operation.The present embodiment
In, preset mode is the operating mode of the small temperature difference, i.e. the difference of the simulation air conditioner return air temperature of machine and supply air temperature indoors
It works under lesser mode.Specifically, reducing refrigerating capacity into after small temperature difference operating mode and improving indoor unit blower
Revolving speed, it is preferred that the revolving speed that can control indoor unit blower is higher than the first preset rotation speed threshold value.In the present embodiment, first is default
Rotary speed threshold value can be it is preset, and the first preset rotation speed threshold value can be higher than air conditioner in initial launch in common mould
Rotation speed of fan under formula.
In this way, when room temperature and all lower outdoor temperature, by reducing the refrigerating capacity of air conditioner and improving interior
The temperature difference of the revolving speed of machine blower, the supply air temperature and return air temperature that can make indoor unit reduces.Since room temperature is lower,
It is exactly that air return temperature value is lower, and supply air temperature is lower than return air temperature in cooling mode, therefore reduces supply air temperature and return air
The supply air temperature of indoor unit can be improved in the difference of temperature, and the feeling of indoor occupant will not be cooler or colder, improves personnel's sense
The comfort of feel.
Preferably, the refrigerating capacity for reducing air conditioner can be the flow velocity for reducing refrigerant in refrigerant flow duct, and drop
The compressor operating frequency of low air conditioner or the revolving speed for reducing outdoor unit blower, certainly, in the compressor fortune for reducing air conditioner
The revolving speed of outdoor unit blower can also be also reduced while line frequency.
In order to control the refrigerating capacity of air conditioner, using two groups of orifice unions are arranged in the air conditioner of the present embodiment, such as Fig. 3 institute
Show, blower is provided in the indoor unit of air conditioner, and outdoor unit is also equipped with a blower.Also, the indoor unit of air conditioner
It is inside provided with an evaporator 28, the fan 27 of indoor unit is arranged near evaporator 28, and outdoor unit of the air conditioner is provided with
One condenser 13, and the fan 14 of outdoor unit is arranged near condenser 13.
Two groups of orifice unions are additionally provided in the flow duct of refrigerant, wherein one group of orifice union includes being connected in series
Electric expansion valve 21 and capillary 22, another group of orifice union include the shut-off valve 31 and capillary 32 being connected in parallel.Its
In, shut-off valve 31 and capillary 32 are connected in parallel and constitute first group of orifice union 30, and electric expansion valve 21 and capillary 22
Constitute second group of orifice union.In practical application, capillary 32 is used as current limiting device, electric expansion valve substitution can be used.
It can be seen from figure 3 that in the air conditioner, electric expansion valve 21, capillary 22, first throttle component 30, evaporator 28, pressure
It is sequentially connected between contracting machine 25 and condenser 23 by pipeline, constitutes the flow circuits of refrigerant.When air conditioner is run, refrigerant can
Followed by electric expansion valve 21,22, first groups of orifice unions 30 of capillary, evaporator 28, compressor 25 and condenser
23, in refrigeration, refrigerant discharges heat when flowing through condenser 23, the temperature of refrigerant reduces, and refrigerant when evaporator 28 by inhaling
Reduction when receiving heat, refrigerant temperature raising, and again passing by condenser 23, so recycles.
When air conditioner work in the normal mode, shut-off valve 31 is opened, since the cross-sectional area of shut-off valve 31 at this time is larger,
Refrigerant is flowed through from shut-off valve 31 without flowing through from capillary 32.At this point, the flowing velocity of refrigerant is very fast, it is ensured that air conditioner
Refrigerating capacity.When executing step S3, air conditioner enters preset mode operation, can be reduced by way of closing shut-off valve 31
The flow velocity of refrigerant.After shut-off valve 31 is closed, refrigerant can not can only be flowed, due to hair by shut-off valve 31 by capillary 32
The cross-sectional area of tubule 32 is smaller, thus refrigerant pass through capillary 32 when, the flow of unit time is smaller, thus realize reduce it is cold
The purpose of matchmaker's flow velocity.
At the same time, as the flow velocity of refrigerant reduces, it is also necessary to reduce the running frequency of compressor 25, and reduce outdoor
The revolving speed of the blower of machine, to reduce the refrigerating capacity of air conditioner.Preferably, the running frequency of compressor 25 is dropped to preset
Frequency threshold is hereinafter, and it is possible to drop to the second preset rotation speed threshold value or less for the revolving speed of outdoor unit blower.
After entering preset mode, the refrigerating capacity of air conditioner reduces, and the revolving speed of indoor unit blower increases, this
The difference of sample, air conditioner supply air temperature and return air temperature reduces, i.e., supply air temperature improves, and the wind speed of machine blower mentions indoors
After height, the blowing amount of indoor unit is also increase accordingly, and air conditioner blows out the big higher wind of amount temperature, and indoor environment can be improved
Temperature improves the comfort of human body so that indoor occupant is felt to warm.
Into after preset mode operation, air conditioner executes step S5, continues to acquire indoor temperature value and outdoor temp angle value,
And judge whether indoor temperature value is higher than third preset temperature value or whether outdoor temp angle value is higher than the 4th preset temperature value.
If indoor temperature value is higher than third preset temperature value or outdoor temp angle value is higher than the 4th preset temperature value, step S5's
Judging result is yes, execution step S6；If indoor temperature value is not higher than third preset temperature value, and outdoor temp angle value is not yet
Higher than the 4th preset temperature value, then the judging result of step S5 is no, then returns to step S3, is maintained under preset mode and transports
Row.
In the present embodiment, third preset temperature value and the 4th preset temperature value are all predetermined temperature values, also, the
Three preset temperature values are higher than the first preset temperature value, and the 4th preset temperature value is higher than the second preset temperature value.Specifically, third
Preset temperature value can be 31 DEG C, i.e., 3 DEG C higher than the first preset temperature value；4th preset temperature value can be 41 DEG C, i.e., than
Two preset temperature values are 3 DEG C high.It is, the difference in the present embodiment, between third preset temperature value and the first preset temperature value
Equal to the difference between the 4th preset temperature value and the second preset temperature value.
If the judging result of step S5 be it is yes, then follow the steps S6, air conditioner is back to general mode operation, i.e. air-conditioning
The refrigerating capacity of device increases.Specifically, flow velocity of the refrigerant in refrigerant flow duct can be increased, as shown in figure 3, by shut-off valve 31
It opens, at this point, refrigerant can flow through first group of orifice union 30 by shut-off valve 31, and is no longer flow through capillary 32.Due to cutting
Only the cross-sectional area of valve 31 is larger, and the flow of unit time is larger when refrigerant flows through shut-off valve 31, flows through flow velocity after shut-off valve 31
Comparatively fast.
Also, it is back to after general mode, the running frequency of compressor can be improved, and improve outdoor unit blower
Revolving speed, to cooperate the raising of refrigerating capacity, it is ensured that the blowout air temperature of indoor unit is lower, avoids room temperature excessively high.In addition, indoor
The revolving speed of machine blower may remain in higher revolving speed, can also slightly reduce, for example, from preset mode enter general mode with
Afterwards, keep indoor unit revolving speed constant, but supply air temperature is lower, can quickly reduce room temperature.
As it can be seen that third preset temperature value is set higher than the first preset temperature value, and the 4th preset temperature by the present embodiment
Value is set higher than the second preset temperature value, rather than by third preset temperature value set it is equal with the first temperature value, by the 4th
Preset temperature value setting is equal with second temperature value, can be to avoid indoor temperature value near the first preset temperature value, outdoor temp
When angle value is near the second preset temperature value, air conditioner enters repeatedly, exits small temperature difference mode, so that it is guaranteed that air conditioner operation
Stability.
Certainly, when practical application, third preset temperature value can also be set into, Huo Zhe equal with the first preset temperature value
Four preset temperature values are equal with the second preset temperature value.Alternatively, the difference of third preset temperature value and the first preset temperature value is not
It is centainly equal with the difference of the second preset temperature value with the 4th preset temperature value, such as the first preset temperature value can be 28 DEG C,
Third preset temperature value can be 31 DEG C, and the difference of the two is 3 DEG C.And the second preset temperature value can be 38 DEG C, the 4th is default
Temperature value can be 40 DEG C, and the difference of the two is 2 DEG C.
In addition, the Rule of judgment of step S5, which is also possible to indoor temperature value, is greater than third preset temperature value, and outdoor temp
Angle value is greater than the 4th preset temperature value, that is, only indoor temperature value is greater than third preset temperature value and outdoor temp angle value
When greater than four preset temperature values, the operation of preset mode can be just exited.
After being back to general mode operation, step S7 is executed, air conditioner judges whether to receive control out of service
Signal processed, for example whether the signal out of service of remote controler sending is received, if so, then exiting the control to air conditioner.Such as
Fruit is not received by signal out of service, then returns to step S2, acquires indoor temperature value, outdoor temp angle value again, and
And compare the indoor temperature value of acquisition and the first preset temperature value, by the outdoor temp angle value of acquisition and the second preset temperature
Value compares, and judges whether to meet the condition for entering preset mode operation, enters preset mode operation if met again
Condition thens follow the steps S3, is again introduced into preset mode operation.
If the judging result of step S2 be it is no, then follow the steps S4, air conditioner holding is run in the normal mode, i.e., not
Refrigerating capacity can be reduced, the flow velocity of refrigerant maintains normal flow velocity.Then step S8 is executed, judges whether air conditioner receives and stops
Otherwise the signal only run, returns to step S2, judges current environment again if so, then exiting the control to air conditioner
Whether temperature meets the condition run into preset mode including indoor temperature value, outdoor temp angle value.
As it can be seen that the present embodiment air conditioner by constantly judging indoor temperature value, outdoor temp angle value, can preset
It is toggled between mode and general mode, specifically, the preset mode of air conditioner is small temperature difference operating mode, it is air conditioner chamber
The operating mode when return air temperature of interior machine and the smaller temperature difference of supply air temperature.The present embodiment temperature value, outdoor temperature indoors
Enter preset mode operation when being worth lower, to improve supply air temperature, when indoor temperature value, outdoor temp angle value are higher, exits
Preset mode runs and is back to general mode operation, it is ensured that supply air temperature is lower, makes the human body sensory of indoor occupant more
Comfortably, it avoids crossing the situation generation waken up as low as there is jelly because of supply air temperature.
Applicants experimentally found that central location is a certain in the room when the metope temperature in room is 30 DEG C
The temperature of a position is stablized at 28 DEG C, and the load of air conditioner is 1073W, and the temperature of central location is stablized 27.4 in the room

The temperature of position is stablized at 29.5 DEG C, and the load of air conditioner is 1174W at this time.
If the metope temperature in night room is 30 DEG C or less, air conditioner enters preset mode work, that is, enters small
The work of temperature difference mode, for a rated cooling capacity is the air conditioner of 3500W, indoor unit supply air temperature and return air temperature at this time
The difference of degree is 7 DEG C, and air output is 599M at this time3/ H increases air output by 100M if opening the panel of air conditioner3/ H, i.e.,
Air output increases to about 700M3/ H, supply air temperature and the difference of return air temperature are 6 DEG C at this time.In this way, by increasing air output
Reduce the difference of supply air temperature and return air temperature, i.e., supply air temperature reduces, human body sensory is more comfortable.
It should be noted that temperature when above-mentioned experiment by room inner wall surface temperature as reference, metope temperature is not
Equal to room temperature, also it is not equal to outdoor temperature, but in general, when metope temperature is higher, the return air temperature that indoor unit detects
It spends also higher.
