And it is got in the first preset rotation speed R1 work with introducing outdoor air.
The control method and air conditioner 100 of the air conditioner of embodiment of the present invention, pass through the dew-point temperature T3 of outdoor air
It is worked with the difference of indoor air temperature T2 to control the wind turbine 16 of air cleaning unit 10, in this way, introducing outdoor fresh sky
There is condensation and influences the performance of air conditioner 100 in the air that can be avoided enter into air cleaning unit 10 when gas, and

The part either dynamically distributed.Processor 40 can be the processor 40 of the either air conditioner 100 of independent processor 40
It is special or dynamically distribute a part.
Referring to Fig. 1, air cleaning unit 10 can be new blower fan apparatus, and air cleaning unit 10 includes air inlet
Mouth 12, filter screen 14, wind turbine 16 and air outlet 19.Processor 40 controls wind turbine 16 and is rotated such that air inlet 12 with certain wind speed
Outdoor fresh air is introduced into interior, processing is filtered to introduced air by filter screen 14, filter screen 14 can wrap
Include antibacterial and mouldproof primary filter, sponge active carbon layer, cellular activated carbon layer and efficient filter.Processor 40 controls wind turbine 16 and will filter
Air afterwards is sent out via air outlet 19.In this way, indoor air can be purified, it is more advantageous to the health of user.The present invention
In embodiment, the air duct in air cleaning unit 10 is substantially in Z-shaped.In one example, it can detect at air inlet 12
Outside air temperature determines the dew-point temperature T3 of outdoor air.
The dew-point temperature of air refers to that air is all immovable in moisture content and air pressure, is cooled to saturation state
When temperature.If the temperature of air is higher than the dew-point temperature of air, air is in unsaturated state at this time, if air themperature is less than
The dew-point temperature of air, at this time air be in saturation state, air can be condensed into droplet, that is to say, that condensation has occurred in air
The case where.
In the related art, when outside air temperature T1 is more than indoor air temperature T2 (T1 ＞ T2), and air conditioner is opened
When opening fresh air function, the air of outdoor higher temperature is into new blower fan apparatus, and the newly temperature of the air hose internal face of blower fan apparatus
Relatively low, condensation occurs for the air for being easy to cause the outdoor higher temperature for entering aeration device in this way, condenses into droplet, to
The performance of new blower fan apparatus is influenced, and user experience is bad.
And in embodiment of the present invention, the difference of dew-point temperature T3 and indoor air temperature T2 by judging outdoor air
Whether it is less than first threshold Ta, is less than first threshold Ta in the difference of the dew-point temperature T3 and indoor air temperature T2 of outdoor air
When just start air cleaning unit 10 wind turbine 16 start and with the first preset rotation speed R1 to introduce outdoor air into interior, in this way
It can make the outdoor air got in that the feelings of condensation occur to avoid the excessive temperature differentials due to outdoor temperature and indoor temperature
Condition.
It should be noted that if the difference of the dew-point temperature T3 and indoor air temperature T2 of outdoor air reach the first threshold values
Ta, and the air that the first threshold values Ta is outdoor higher temperature enters the sky at the air hose inner wall of the stylish blower fan apparatus of new blower fan apparatus
The critical value of condensation situation just occurs for gas.That is, work as the dew-point temperature T3 and indoor air temperature T2 of outdoor air
When difference is less than the first threshold values Ta, condensation risk will not occur for air conditioner 100 or the probability of generation condensation is extremely low, work as outdoor air
The difference of dew-point temperature T3 and indoor air temperature T2 when being not less than the first threshold values Ta, condensation risk can occur for air conditioner 100.
It should be pointed out that first threshold Ta and the first preset rotation speed R1 can be configured according to practical situation.
In one example, the range of first threshold Ta may be configured as 0 DEG C<Ta<14℃.When first threshold Ta ranging from
9℃≤Ta<At 14 DEG C, the first preset rotation speed R1 is the slow-speed of revolution, for example, 0r/min<R1≤400r/min；When first threshold Ta's
Range takes 5 DEG C≤Ta<9 DEG C, the first preset rotation speed R1 is middle rotating speed, for example, 400r/min<R1≤800r/min；When the first threshold
The range of value Ta takes 0 DEG C<Ta<5 DEG C, the first preset rotation speed R1 is high rotating speed, for example, 800r/min<R1≤1200r/min.
In other words, the size of first threshold Ta and the size of the first preset rotation speed R1 are negative correlativing relation.It is appreciated that
First threshold Ta is smaller, and the first preset rotation speed R1 is bigger, in other words, the dew-point temperature T3 and indoor air temperature of outdoor air
The difference of T2 is smaller, and the rotating speed that processor 40 controls the wind turbine 16 of air cleaning unit 10 is also bigger.Such benefit is, when
When above-mentioned difference falls into smaller first threshold Ta, above-mentioned difference is smaller, it is possible to the rotating speed for suitably improving wind turbine 16, with
Fresh air is introduced quickly；When above-mentioned difference falls into relatively large first threshold Ta, above-mentioned difference is relatively large, it is possible to appropriate
Ground reduces the rotating speed of wind turbine 16, slowly to introduce fresh air；When above-mentioned difference falls into the first threshold Ta compared with bigger, above-mentioned difference
It is worth bigger, it is possible to the rotating speed for suitably further decreasing wind turbine 16, more slowly to introduce fresh air.
In this way, can be adjusted by adjusting the correspondence of first threshold Ta and the first preset rotation speed R1 into entering the room in this way
Can also avoiding air while interior air capacity, there is a situation where condensations, so as to improve environmental amenity degree, user's body
The property tested is good.
Specifically, in one example, the ranging from 9 DEG C≤Ta of first threshold Ta<14 DEG C, outside air temperature T1 is 40
Degree Celsius, relative humidity 60%, the dew-point temperature T3 that can obtain corresponding outdoor air by searching for table or curve at this time is
30.93 degrees Celsius.If indoor air temperature T2 is 21 degrees Celsius at this time, dew-point temperature T3 and the Interior Space temperature of outdoor air
The difference for spending T2 is 9.93 degrees Celsius, since the difference (9.93 degrees Celsius) falls into the 9 DEG C≤Ta of range of first threshold Ta<14℃
It is interior, therefore the wind turbine 16 that processor 40 controls air cleaning unit 10 is started and is introduced with the rotating speed of the slow-speed of revolution (such as 100r/min)
Outdoor air is got in.
In another example, the ranging from 5 DEG C≤Ta of first threshold Ta<9 DEG C, outside air temperature T1 is 40 Celsius
Degree, relative humidity 60%, the dew-point temperature T3 that can obtain corresponding outdoor air by searching for table or curve at this time are 30.93
Degree Celsius.If indoor air temperature T2 is 23 degrees Celsius at this time, the dew-point temperature T3 and indoor air temperature T2 of outdoor air
Difference be 7.93 degrees Celsius, since the difference (7.93 degrees Celsius) falls into the 5 DEG C≤Ta of range of first threshold Ta<In 9 DEG C, therefore
The wind turbine 16 that processor 40 controls air cleaning unit 10 is started and is introduced with the rotating speed of middle rotating speed (such as 800r/min) outdoor
Air is got in.
In another example, ranging from 0 DEG C of first threshold Ta<Ta<5 DEG C, outside air temperature T1 is 40 degrees Celsius,
Relative humidity is 60%, can obtain the dew-point temperature T3 of corresponding outdoor air by searching for table or curve at this time and be taken the photograph for 30.93
Family name's degree.If indoor air temperature T2 is 26 degrees Celsius at this time, the dew-point temperature T3's and indoor air temperature T2 of outdoor air
Difference is 4.93 degrees Celsius, since the difference (4.93 degrees Celsius) falls into ranging from 0 DEG C of first threshold Ta<Ta<In 5 DEG C, therefore
The wind turbine 16 that processor 40 controls air cleaning unit 10 is started and is introduced with the rotating speed of high rotating speed (such as 1200r/min) outdoor
Air is got in.
Look-up table or curve are storable in air conditioner 100 or are obtained from high in the clouds by air conditioner 100.It is appreciated that first
Threshold value can also be a value, rather than a range.For example, first threshold may be configured as the occurrences such as 5,8 or 10.
In some embodiments, air conditioner 100 includes temperature-adjusting device 20, and control method includes step：
S30 is more than or equal to first threshold in the difference of the dew-point temperature T3 and indoor air temperature T2 of outdoor air
Air cleaning unit 10 is controlled when Ta to be stopped, and controls the refrigeration of temperature-adjusting device 20.
The step S30 of the control method of the air conditioner of embodiment of the present invention can be realized by processor 40.That is,
Processor 40 for execute program with realize the difference in the dew-point temperature T3 and indoor air temperature T2 of outdoor air be more than or
Control air cleaning unit 10 is stopped when person is equal to first threshold Ta, and controls the refrigeration of temperature-adjusting device 20.
Due in the present embodiment, the difference of the dew-point temperature T3 and indoor air temperature T2 of outdoor air be more than or
Air cleaning unit 10 is controlled when equal to first threshold Ta to be stopped, and controls the refrigeration of temperature-adjusting device 20, in this way, in sky
Adjust device refrigeration mode under, in this way can to avoid air conditioner 100, there is a situation where condensations, to which making for air conditioner 100 can be improved
Use performance.
Specifically, the temperature-adjusting device 20 and air cleaning unit 10 of present embodiment are being wholely set settings.Example
Such as cabinet-type air conditioner, temperature-adjusting device 20 can be located at the top of air cleaning unit 10.Certainly, air conditioner 100 is also to be
On-hook is not particularly limited herein.Temperature-adjusting device 20 can be used for freezing or heat.In the present embodiment, temperature is adjusted
Device 20 is for freezing.
It is appreciated that the range of first threshold Ta may be configured as 0 DEG C<Ta<14℃.In one embodiment, outdoor empty
Temperature degree T1 is 40 degrees Celsius, relative humidity 60%, and the dew-point temperature T3 of corresponding outdoor air is 30.93 Celsius at this time
Degree.If indoor air temperature T2 is 16 degrees Celsius at this time, the difference of the dew-point temperature T3 and indoor air temperature T2 of outdoor air
Value is 14.93 degrees Celsius, since the difference (14.93 degrees Celsius) is not 0 DEG C in the range T of first threshold Ta<Ta<In 14 DEG C,
Therefore the wind turbine 16 that processor 40 controls air cleaning unit 10 is stopped.At this point, 40 temperature controllable regulating device of processor
20 operations are to freeze, under keeping air conditioner 100 in refrigeration mode.
Referring to Fig. 4, in some embodiments, the dew-point temperature T3 of outdoor air passes through following steps in step S10
It obtains：
S12 acquires outside air temperature T1 and outside air humidity RH1；With
S14, according to the relation data of the air themperature to prestore, the air humidity to prestore and the dew-point temperature to prestore determine with
The dew-point temperature T3 of outside air temperature T1 and the corresponding outdoor airs of outside air humidity RH1.
In this way, in this way can be with the dew-point temperature T3 of quick obtaining outdoor air.
Specifically, referring to Fig. 3, air conditioner 100 includes outdoor temperature sensor 50 and outside humidity sensor 60,
Outdoor temperature sensor 50 is for detecting outside air temperature T1, and outside humidity sensor 60 is for detecting outside air humidity
RH1。
It is appreciated that the relation data of the air themperature to prestore, the air humidity to prestore and the dew-point temperature to prestore includes

Outer air themperature T1 and outside air humidity RH1, and the dew point of corresponding outdoor air can be found by curve or look-up table
Temperature T3.
Referring to Fig. 5, in some embodiments, the control method includes step：
S40 judges the dew point temperature of room air when outside air temperature T1 is less than indoor air temperature T2 (T1 ＜ T2)
Whether the difference for spending T4 and outside air temperature T1 is less than second threshold Tb；
S50 is controlled when the difference of the dew-point temperature T4 and outside air temperature T1 of air are less than second threshold Tb indoors
The wind turbine 16 of air cleaning unit 10 is started and is got in the second preset rotation speed R2 work with introducing outdoor air.
The step S40 to S50 of the control method of the air conditioner of embodiment of the present invention can be realized by processor 40.Also
It is to say, processor 40 judges interior for executing program to realize when outside air temperature T1 is less than indoor air temperature T2
Whether the difference of the dew-point temperature T4 and outside air temperature T1 of air are less than second threshold Tb；The dew-point temperature of air indoors
The wind turbine 16 of control air cleaning unit 10 starts and with the when the difference of T4 and outside air temperature T1 are less than second threshold Tb
Two preset rotation speed R2 work are got in introducing outdoor air.
In the related art, when outside air temperature T1 is less than indoor air temperature T2 (T1 ＜ T2), and air conditioner is opened
When opening fresh air function, the air of outdoor lower temperature enters new blower fan apparatus, and the temperature of the outer wall of indoor new blower fan apparatus
It is higher, and the temperature of the air hose internal face of new blower fan apparatus is relatively low, when being easy to cause the air for introducing outdoor lower temperature in this way
So that the room air at indoor new blower fan apparatus outer wall is easy to happen condensation, air condenses into droplet, to
The performance of new blower fan apparatus is influenced, and user experience is bad.
The control method of the air conditioner of embodiment of the present invention passes through dew-point temperature T4 and the outdoor air temperature of room air
It spends the difference of T1 and works to control the wind turbine 16 of air cleaning unit 10, in this way, outdoor can introduced newly to avoid air conditioner 100
There is condensation and influences the performance of air conditioner 100 in room air when fresh air, and embodiment of the present invention can improve
The comfort level of indoor environment, user experience are good.
It should be noted that if the difference of the dew-point temperature T4 and outside air temperature T1 of room air are second threshold
Tb, and the air that second threshold Tb is outdoor lower temperature enters the room at the air hose outer wall of the stylish blower fan apparatus of new blower fan apparatus
The critical value of condensation situation will not just occur for interior air.That is, as the dew-point temperature T4 and outdoor air of room air
When the difference of temperature T1 is less than second threshold Tb, condensation risk will not occur for air conditioner 100 or the risk of generation condensation is extremely low, when
When the difference of the dew-point temperature T4 and outside air temperature T1 of room air are not less than second threshold Tb, air conditioner 100 can occur
Condensation risk.
It should be pointed out that second threshold Tb and the second preset rotation speed R2 can be configured according to practical situation.
In the present embodiment, the range of second threshold Tb may be configured as 0 DEG C<Tb<17℃.When the range of second threshold Tb
For 7 DEG C≤Tb<At 17 DEG C, the second preset rotation speed R2 is the slow-speed of revolution, such as 0r/min<R2≤400r/min；As second threshold Tb
Range take 3 DEG C≤Tb<7 DEG C, the second preset rotation speed R2 is middle rotating speed, such as 400r/min<R2≤800r/min；When the second threshold
The range of value Tb takes 0 DEG C<Tb<3 DEG C, the second preset rotation speed R2 is high rotating speed, such as 800r/min<R2≤1200r/min.
That is, the size of second threshold Tb and the size of the second preset rotation speed R2 are negative correlativing relation.It is appreciated that
Second threshold Tb is smaller, and the second preset rotation speed R2 is bigger, that is to say, that the dew-point temperature T4 of room air and outdoor air temperature
The difference for spending T1 is smaller, and the rotating speed that processor 40 controls the wind turbine 16 of air cleaning unit 10 is also bigger.
Such benefit is that, when above-mentioned difference falls into smaller second threshold Tb, above-mentioned difference is smaller, it is possible to suitable
The rotating speed of wind turbine 16 is improved in locality, to introduce fresh air quickly；It is above-mentioned when above-mentioned difference falls into relatively large second threshold Tb
Difference is relatively large, it is possible to the rotating speed for suitably reducing wind turbine 16, slowly to introduce fresh air；When above-mentioned difference is fallen into more more
When big second threshold Tb, above-mentioned difference bigger, it is possible to the rotating speed for suitably further decreasing wind turbine 16, with more slowly
Introduce fresh air.
In this way, can be adjusted by adjusting the correspondence of second threshold Tb and the second preset rotation speed R2 into entering the room in this way
Can also avoiding air while interior air capacity, there is a situation where condensations, so as to improve environmental amenity degree, user's body
The property tested is good.
Specifically, in one example, the ranging from 7 DEG C≤Tb of second threshold Tb<17 DEG C, indoor air temperature T2 is 25
Degree Celsius, relative humidity 60%, the dew-point temperature T4 that can obtain corresponding room air by searching for table or curve at this time is
16.72 degrees Celsius.If the temperature T1 of outdoor air is 7 degrees Celsius at this time, the dew-point temperature T4 and outdoor air of room air
Temperature T1 difference be 9.72 degrees Celsius, since the difference (9.72 degrees Celsius) falls into the 7 DEG C≤Tb of range of second threshold Tb<
In 17 DEG C, therefore the wind turbine 16 that processor 40 controls air cleaning unit 10 starts and with the rotating speed of the slow-speed of revolution (such as 100r/min)
Outdoor air is introduced to get in.In another example, the ranging from 3 DEG C≤Tb of second threshold Tb<7 DEG C, Interior Space temperature
It is 25 degrees Celsius to spend T2, and relative humidity 60% can obtain the dew point of corresponding room air by searching for table or curve at this time
Temperature T4 is 16.72 degrees Celsius.If at this time the temperature T1 of outdoor air be 11 degrees Celsius, the dew-point temperature T4 of room air with
The difference of outside air temperature T1 is 5.72 degrees Celsius, since the difference (5.72 degrees Celsius) falls into the range 3 of second threshold Tb
℃≤Tb<In 7 DEG C, therefore the wind turbine 16 that processor 40 controls air cleaning unit 10 starts and with middle rotating speed (such as 800r/min)
Rotating speed introduce outdoor air get in.In another example, ranging from 0 DEG C of second threshold Tb<Tb<3 DEG C, Interior Space
Temperature degree T2 is 25 degrees Celsius, and relative humidity 60% can obtain corresponding room air by searching for table or curve at this time
Dew-point temperature T4 is 16.72 degrees Celsius.If outside air temperature T1 is 15 degrees Celsius at this time, the dew-point temperature T4 of room air
Difference with outside air temperature T1 is 1.72 degrees Celsius, since the difference (1.72 degrees Celsius) falls into the range of second threshold Tb
It is 0 DEG C<Tb<In 3 DEG C, therefore the wind turbine 16 that processor 40 controls air cleaning unit 10 starts and with high rotating speed (such as 1200r/
Min rotating speed) introduces outdoor air and gets in.
It is appreciated that second threshold Tb can also be a value, rather than a range.For example, second threshold Tb can be set
It is set to the occurrences such as 4,7 or 11.
In some embodiments, air conditioner 100 includes temperature-adjusting device 20, and control method includes step：
