Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The air conditioner proposed according to embodiments of the present invention and its control method and control device described below in conjunction with the accompanying drawings.
In an embodiment of the present invention, as illustrated in fig. 1 and 2, air conditioner may include compressor 1, four-way valve 3, outdoor heat exchange
Device 6, indoor heat exchanger 9 and throttle part 8.Wherein, the exhaust outlet of compressor 1 is connected with the first end of four-way valve 3, four-way valve 3
Second end be connected with one end of indoor heat exchanger 9, the other end of indoor heat exchanger 9 is connected with one end of throttle part 8, throttling
The other end of component 8 is connected with one end of outdoor heat exchanger 6, the other end of outdoor heat exchanger 6 and the third end phase of four-way valve 3
Even, the 4th end of four-way valve 3 is connected with the gas returning port of compressor 1.
When air conditioner is run with heating mode, as shown in figures 1 and 3, A/B conductings, the C/D conductings of four-way valve 3, from pressure
A/B end of the high pressure gaseous refrigerant through four-way valve 3 that contracting machine 1 comes out gets in heat exchanger 9 and is exchanged heat and (release heat),
High temperature and pressure gas-liquid two-phase mixture after heat exchange is by 8 reducing pressure by regulating flow of throttle part, the low-temp low-pressure gas-liquid after reducing pressure by regulating flow
Two-phase mixtures body enters outdoor heat exchanger 6 and is exchanged heat and (absorb heat), and the low-temp low-pressure gaseous coolant after heat exchange is through four-way valve 3
C/D ends return to compressor 1.
After air conditioner heat-production shutdown, indoor heat exchanger 9 is in the condition of high temperature, and waste heat is to external diffusion, kernel (indoor heat exchange
Device) in thermal expansion state, air-conditioner shell (indoor unit casing) environment disposed within, since indoor environment temperature is relatively low, shell
Body is in the holding state of shrinkage, it is easy to there is the shrinkage because of housing and the thermal expansion of kernel, and inside and outside causing between parts
Friction and Extrusion sends out abnormal sound.
To solve the above problems, the present invention proposes a kind of control method of air conditioner, it is right after air conditioner heat-production shutdown
The four-way valve of air conditioner carries out commutation processing, without additionally increasing the materials such as sponge, flannelette, adhesive tape, improves air conditioner and is heating
The sound that expands with heat and contract with cold of generation in shutdown process.
Fig. 5 is the flow chart of the control method of air conditioner according to embodiments of the present invention.As shown in figure 5, the present invention is implemented
The control method of the air conditioner of example may include following steps：
S1, after air conditioner heat-production shuts down, control four-way valve commutates, and the indoor fan of air conditioner is controlled to be in and is closed
Closed state.
S2 judges whether four-way valve commutates completion.
S3 if four-way valve commutation is completed, controls compressor start, to control the liquid refrigerant stream by throttle part
Indoor heat exchanger is crossed, so that indoor heat exchanger is in synchronous cooling state with indoor unit shell.
According to one embodiment of present invention, in the start-up course of compressor, also at the outdoor fan of control air conditioner
In closed state, and indoor fan is controlled to remain off.
Specifically, when air conditioner is run with heating mode, A/B conductings, the C/D conductings of four-way valve, as shown in figure 3, from
The high pressure gaseous refrigerant that compressor comes out gets in heat exchanger through four-way valve D/C and exchanges heat, then through throttle part section
Enter outdoor heat exchanger after stream decompression, after outdoor heat exchanger is exchanged heat, compressor is returned to by four-way valve A/B.
After air conditioner heat-production shutdown, commutation processing is carried out to the four-way valve of air conditioner, four-way valve D/A conductings, C/B are led
Logical, as shown in Figure 2 and Figure 4, during commutation, indoor fan is closed.After the completion of four-way valve commutation, compression
Machine starts operation, and during startup, control outdoor fan is closed.After compressor start operation, such as Fig. 2 institutes
Show, the high pressure gaseous refrigerant come out from compressor first passes through outdoor heat exchanger and exchanges heat, and the gas-liquid two-phase after heat exchange mixes
Zoarium makes liquid refrigerants be admitted to indoor heat exchanger after throttle part reducing pressure by regulating flow, and liquid refrigerants absorbs indoor unit heat exchange
The waste heat of device so as to eliminate nuclear heat source in air conditioner, makes kernel synchronous with housing in the state of cooling, and without additionally increasing
The materials such as sponge, flannelette, adhesive tape effectively improve the sound that expands with heat and contract with cold of generation of the air conditioner in shutdown process is heated.
Further, according to one embodiment of present invention, after compressor start runs preset time, compressor is controlled
It is out of service, and four-way valve is controlled to commutate again, to restore to original state.Wherein, preset time can according to actual conditions into
Rower is determined.
It is completed that is, commutating in four-way valve, after compressor start operation a period of time, indoor heat exchanger and indoor unit
Shell is in synchronous cooling state, eliminates the heat source of indoor heat exchanger, is not in the sound that expands with heat and contract with cold, and control compressor stops
Operation, and four-way valve is controlled to commutate again, restore to four-way valve D/C conductings, A/B conductings during original state, i.e. heating operation, with
Air conditioner is made normally to heat, meets user demand.
In conclusion the control method of air conditioner according to embodiments of the present invention, after air conditioner heat-production shuts down, control four
Port valve commutates, and the indoor fan of air conditioner is controlled to be closed, and judges whether four-way valve commutates completion, if four
Port valve commutation is completed, then controls compressor start, flows through indoor heat exchanger by the liquid refrigerants of throttle part to control, so that
Indoor heat exchanger is in synchronous cooling state with indoor unit shell.This method can be effectively improved air conditioner and be closed in heating as a result,
During machine, because of the heat expansion of indoor heat exchanger and the shrinkage of indoor unit shell, friction and Extrusion is sent out between leading to inside and outside parts
Abnormal sound.
Corresponding above-described embodiment, the embodiment of the present invention also proposed a kind of non-transitorycomputer readable storage medium,
Computer program is stored thereon with, which realizes the control method of above-mentioned air conditioner when being executed by processor.
The non-transitorycomputer readable storage medium of the embodiment of the present invention, by the controlling party for performing above-mentioned air conditioner
Method can be effectively improved air conditioner in shutdown process is heated, and because of the heat expansion of indoor heat exchanger and the shrinkage of indoor unit shell, lead
The abnormal sound that friction and Extrusion is sent out between parts inside and outside cause.
