When reduce first throttle component 7 aperture.
As a result, by above-mentioned setting, when air conditioner is in refrigeration mode, first throttle component 7 is not saved refrigerant
Stream decompression, so as to prevent 5 surface of refrigerant pipeline from generating condensed water.When air conditioner is in heating mode, the second throttling group
Part 8 does not carry out reducing pressure by regulating flow to refrigerant, so that being also possible to prevent 5 surface of refrigerant pipeline generates condensed water.It thus not only can be right
Electrically-controlled component 6 is effectively radiated, and the running stability of air conditioner can also be promoted.
The control method of air conditioner according to an embodiment of the present invention, operation is more convenient, not only refrigerant pipeline 5 can be made right
Electrically-controlled component 6 is effectively radiated, and can also prevent 5 surface of refrigerant pipeline from generating condensed water, and then can prevent condensation flow
Cause the control circuit of refrigeration system 100 short circuit occur to electrically-controlled component 6, greatly improves the running stability of air conditioner.
As shown in figure 4, in some embodiments of the invention, the control method of air conditioner can also include: that detection is indoor
The surface temperature T1 of heat exchanger 3 can control the aperture regulation of first throttle component 7 extremely when T1 is less than default surface temperature
Minimum is to end refrigerant pipeline 5.For example, above-mentioned default surface temperature can be 0 DEG C.It is understood that working as indoor heat exchanger 3
Surface temperature T11≤0 DEG C when, there is freeze protection in refrigeration system 100 at this time, at this time the running frequency of compressor 1 be 0.But
It is when refrigeration system 100 is before carrying out freeze protection, compressor 1 is constantly in the state of low frequency operation, at this time compressor 1
Delivery temperature and outdoor heat exchanger 4 condensation temperature it is very low.After compressor 1 is shut down under this operating condition, due to cold coal temperature
The temperature of the refrigerant pipeline 5 for drastically reducing and causing 7 downstream of first throttle component of degree is lower than dew-point temperature, thus can be in refrigerant
Condensed water is generated on the outer surface of pipeline 5.Therefore, when T1≤0 DEG C, by controlling the aperture regulation of first throttle component 7 extremely
Minimum, the refrigerant that low temperature can be effectively prevented circulate in refrigerant pipeline 5 and make refrigerant pipeline 5 outer surface on generate condensation
Water, it can be ensured that electrically-controlled component 6 can normally be run.
It needs to be illustrated, the value of above-mentioned " default surface temperature " is not limited in 0 DEG C, can be according to actual
Service condition comprehensive selection, the present invention are not particularly limited this.
For example, in a specific example of the invention, the first temperature sensing can be arranged in 3 surface of heat exchanger indoors
Device, the first temperature sensor can detecte the surface temperature of indoor heat exchanger 3.Wherein, the first temperature sensor and compressor 1 divide
It is not connected with the communication of the control mainboard of refrigeration system 100.3 surface of indoor heat exchanger that first temperature sensor can will test
Real time temperature T1 be transferred to control mainboard, when T1≤0 DEG C, control mainboard control compressor 1 running frequency lower be 0,
Compressor 1 stops working.
As shown in figure 3, in some embodiments of the invention, air conditioner may include outdoor fan, the control of air conditioner
Method can also include: that can detecte the table of outdoor environment temperature T2 and outdoor heat exchanger 4 when air conditioner is in refrigeration mode
Face temperature T3, and determine that the temperature difference △ T between T3 and T2 can control outdoor fan if △ T is in preset temperature range
Revolving speed be less than or equal to 300 revs/min；If △ T is less than preset temperature, it can control outdoor fan and stop operating.For example, when 10
When DEG C T≤17 DEG C △ <, the revolving speed that can control outdoor fan is less than or equal to 300 revs/min.When T≤10 DEG C △, can control
Outdoor fan stops operating.
It is understood that refrigerant needs in outdoor heat exchanger 4 and outdoor air when air conditioner is in refrigeration mode
Sufficiently exchanged heat.If 17 DEG C of △ T >, the temperature difference between the surface temperature and outdoor environment temperature of outdoor heat exchanger 4 can be with
The heat exchange demand for meeting refrigerant can control outdoor fan and keep high speed rotation.For example, revolving speed when outdoor fan high speed rotation
It can be 500 revs/min.If 10 DEG C of T≤17 DEG C < △, between the surface temperature and outdoor environment temperature of outdoor heat exchanger 4
The temperature difference is smaller, is difficult to meet heat exchange demand of the refrigerant in outdoor heat exchanger 4 at this time.Pass through the revolving speed of control outdoor fan at this time
It is decreased to less than and is equal to 300 revs/min, it is possible thereby to reduce the air passage rates on 4 surface of outdoor heat exchanger, outdoor can be promoted and changed
Refrigerant temperature in hot device 4, and then the temperature difference between the surface temperature and outdoor environment temperature of outdoor heat exchanger 4 can be increased,
It can satisfy the heat exchange demand of refrigerant.If T≤10 DEG C △, at this time the surface temperature of outdoor heat exchanger 4 and outdoor environment temperature it
Between close to identical, heat exchange efficiency of the refrigerant in outdoor heat exchanger 4 is extremely low, is stopped operating by controlling outdoor fan, can be fast
Speed promotes the refrigerant temperature in outdoor heat exchanger 4, it is possible thereby to increase the surface temperature and outdoor environment temperature of outdoor heat exchanger 4
Between the temperature difference, meet the heat exchange demand of refrigerant.As a result, by above-mentioned setting, it can not only make the operation of air conditioner more flat
Surely, air conditioner can also be made to meet refrigeration and heating needs.
It needs to be illustrated, the value of " preset temperature range " and " preset temperature " in foregoing description simultaneously not only limits
In this, this can be not particularly limited according to actual service condition comprehensive selection, the present invention.
The control method of air conditioner according to the present invention is described in detail with a specific embodiment below with reference to Fig. 3-Fig. 4,
