When device being adjusted to be run with defrosting mode, control air interchanger is closed, and causes room temperature further to decline to avoid ventilation.
To sum up, the control method of the air conditioner proposed according to embodiments of the present invention, after air interchanger unlatching, according to room
Temperature difference between temperature and preset temperature obtains the ventilation running frequency of compressor, and then controls compressor and run according to ventilation
Frequency run.This method adjusts the running frequency of compressor according to temperature difference as a result, and then adjusts the fan-out capability of air conditioner,
To make up the influence that ventilation adjusts air conditioner temperature, it can not only realize healthy ventilation, but also Thermal comfort can be met, improve
User experience.
The present invention has also been proposed a kind of control device of air conditioner.
Fig. 8 is the block diagram of the control device of air conditioner in accordance with another embodiment of the present invention.As shown in figure 8,
The control device of air conditioner includes：Temperature detecting module 100 and control module 200.
Wherein, temperature detecting module 100 is for detecting room temperature；Control module 200 is for controlling air conditioner to heat
Pattern or refrigeration mode operation, and the air interchanger 300 for controlling air conditioner is opened and is taken a breath with default ventilation volume Q, is being changed
After device of air 300 is opened, the ventilation running frequency F of compressor is obtained according to the temperature difference T between room temperature and preset temperature,
And compressor is controlled according to acquired ventilation running frequency F operatings.
Specifically, control module 200 control air conditioner with heat or refrigeration mode run, when control module 200 control
During air interchanger 300 is opened and is taken a breath with default ventilation volume, control module 200 passes through temperature detecting module 10
Room temperature is detected, and the room temperature that temperature detecting module 100 acquires is compared with preset temperature with calculated room temperature
Temperature difference T between degree and preset temperature, and then the ventilation running frequency F of compressor corresponding with the temperature difference T-phase is obtained, and
Control compressor is operated according to corresponding ventilation running frequency F.
The control device of the air conditioner of the embodiment of the present invention adjusts the running frequency of compressor according to temperature difference, and then adjusts
It is comfortable can both to have met room temperature to make up the influence that ventilation adjusts air conditioner temperature for the fan-out capability of whole air conditioner

Further, according to another embodiment of the invention, control module 200 is additionally operable to judge the temperature gap T
Affiliated temperature range, and the corresponding frequency increment Δ f of the temperature range belonging to the temperature difference is obtained, finally compressor is existed
The sum of reference operation frequency f and acquired frequency increment Δ f before air interchanger unlatching is transported as the ventilation of the compressor
Line frequency F.
That is, after exchanging device 300 for and opening, control module 200 is controlled compressor and is transported with acquired ventilation
Line frequency F operations, wherein the running frequency of compressor acquired in acquired ventilation running frequency F=reference operation frequencies f+ increases
Measure Δ f.
The present invention a specific example in, air interchanger 300 open after, control module 200 according to room temperature with
Temperature difference T between preset temperature obtains the ventilation running frequency F of compressor, and controls compressor and run according to the ventilation of acquisition
Frequency F operatings, wherein temperature difference T can be divided into 3 temperature ranges such as T >=5,2≤T<5 and T<2, each temperature range
A corresponding running frequency increment Delta f, such as T >=5 correspond to Δ f=2,2≤T<5 correspond to Δ f=1, T<2 correspond to Δ f
=0, in other words the ventilation running frequency F of temperature difference T and compressor can meet following relationship：
As T >=5, F=f+2；
As 2≤T<When 5, F=f+1；
Work as T<When 2, F=f.
Wherein, f indicates that air interchanger opens the reference operation frequency of preceding compressor.
That is, it is assumed that compressor is run according to frequency f before air interchanger is opened, then air interchanger 300 is opened
Later, frequency f can be used as reference operation frequency, if temperature difference T >=5,2 changing with acquisition are added on the basis of frequency f
Fate line frequency F=f+2, the control compressor of control module 200 is according to ventilation running frequency f+2 operations at this time；If temperature difference 2
≤T<5, then add 1 on the basis of frequency f with the ventilation running frequency F=f+1 of acquisition, the control of control module 200 at this time is compressed
Machine is according to ventilation running frequency f+1 operations；If temperature difference T<2, then using frequency f as ventilation running frequency F, mould is controlled at this time
Block 200 controls compressor according to ventilation running frequency f operations.
According to another embodiment of the invention, when air conditioner is run with defrosting mode, control module 200 is additionally operable to control
Air interchanger 300 processed is closed.
It should be noted that when air conditioner is run with heating mode, outdoor unit of the air conditioner is likely to occur frost,
It controls air conditioner when frosting occurs to run with defrosting mode, the indoor unit of air conditioner is really refrigeration cycle, air conditioner at this time
Heat is not discharged but not into room, it is also possible to absorb the heat in room, room temperature is caused to reduce.Work as sky as a result,
Adjust device when being run with defrosting mode, control module 200 controls air interchanger 300 and closes, to avoid ventilation cause room temperature into
One step declines.
To sum up, the control device of the air conditioner proposed according to embodiments of the present invention, control module air interchanger unlatching after,
According between room temperature and preset temperature temperature difference obtain compressor ventilation running frequency, and then control compressor according to
Running frequency of taking a breath operating.The device adjusts the running frequency of compressor according to temperature difference as a result, and then adjusts the defeated of air conditioner
Output capacity can not only realize healthy ventilation, but also can meet temperature pleasant to make up the influence that ventilation adjusts air conditioner temperature
Property, the user experience is improved.
The invention also provides another air conditioner, air conditioner includes the control device of air conditioner.
Specifically, the control device of air conditioner can be used for controlling air conditioner and be run with heating mode or refrigeration mode, and control
The air interchanger of air conditioner processed is opened and is taken a breath with default ventilation volume, and after air interchanger unlatching, the control of air conditioner fills
