Detailed description of the invention
Fig. 1 is the flow chart based on air-conditioner with fixed frequency halt control method one embodiment of the present invention；
Fig. 2 is the structural block diagram based on air-conditioner with fixed frequency stop control apparatus one embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to drawings and examples,
Invention is further described in detail.
Referring to Figure 1, which show the process based on air-conditioner with fixed frequency halt control method one embodiment of the present invention
Figure.
As schematically shown in Figure 1, which executes the method for shutting down control and includes the following steps:
Step 11: receiving halt instruction in a heating mode.
The halt instruction can be when air conditioner runs heating mode, and user passes through remote controler or air conditioner control panel
Or controlling terminal etc. and input air conditioner halt instruction.
Step 12: outdoor fan power-off shuts down.
When receiving the halt instruction under heating mode, control outdoor fan power-off first shuts down.
In a heating mode, it is shut down by controlling outdoor fan, evaporating temperature can be reduced, also that is, reducing
Therefore evaporating pressure to reduce the condensing pressure of air-conditioner system, reduces compressor operating load.And compressor
The reduction of operating load, compressor and the vibration and stress of piping when helping to improve compressor shutdown.
Step 13: the timing since receiving halt instruction, compressor be delayed the first setting time after power off, stop fortune
Turn.
After receiving halt instruction, compressor is not that power-off shuts down immediately, but from receiving halt instruction
Compressor powers off again after starting timing, reaching the first setting time shuts down.Stop fortune by control compressor delay cut-off
Turn, it can be ensured that condensing pressure there can be sufficient time decline on the basis of outdoor fan stalls.
Step 14: the timing since receiving halt instruction, indoor fan be delayed the second setting time after power off, stop fortune
Turn.
Second setting time is greater than the first setting time, that is, since indoor fan counted receiving halt instruction
When, timing time reach to power off again after the second setting time and shut down, and indoor fan is in compressor power-off, shuts down
It just powers off afterwards.That is, the time that indoor fan shuts down is later than compressor stalling, so as to which the heat of remaining is blown out
Come, waste heat effect is blown in realization as much as possible.
Wherein, the first setting time and the second setting time are pre-stored known times, can easily be adjusted
With, can also by authorization be modified.
As preferred embodiment, the first setting time is 10s, and the second setting time is 20s.
Indoor fan revolving speed is reduced while outdoor fan power-off, shutting down as a kind of specific implementation,
Control indoor fan is with the rotation speed operation after reducing.
Indoor fan revolving speed is reduced, indoor fan is controlled with the rotation speed operation after reducing, specifically includes:
Using the first setting speed as the rotating speed of target of indoor fan, the current rotating speed of indoor fan is set as first and is set
Determine revolving speed, control indoor fan is operated with the first setting speed.
As another specific implementation, for the air conditioner with four-way valve, halt control method further include: from connecing
It receives halt instruction and starts timing, powered off after four-way valve delay third setting time.It is set moreover, third setting time is greater than first
It fixes time and less than the second setting time.
That is, four-way valve power-off time is later than compressor stalling but stalls earlier than indoor fan.The purpose handled in this way is
Commutation causes refrigerant flow direction chaotic and causes to generate biggish vibration when four-way valve powers off in order to prevent.
Wherein, third setting time is also pre-stored known time, can easily be called, can also be by awarding
Power is modified.As preferred embodiment, third setting time is 13s.
Above-mentioned air conditioner halt control method is further described in citing:
The compressor of air-conditioner with fixed frequency heating operation at the 220V/50Hz that powers sends stopping signal by remote controler, this
When start timing.Meanwhile outdoor fan powers off at once, shuts down.The revolving speed of indoor fan is remained unchanged or is reduced.The
After 10s, compressor power-off shuts down.After 3s, four-way valve power-off.After 20s, indoor fan power-off shuts down, room
Interior machine wind-guiding sheet reset.To complete complete stopping process.
Fig. 2 is referred to, which show the structure based on air-conditioner with fixed frequency stop control apparatus one embodiment of the present invention
Block diagram.
As schematically shown in Figure 2, which executes the function of structural unit included by the device for shutting down control, structural unit
And mutual connection relationship difference is as follows:
Halt instruction receiving unit 21, for receiving the halt instruction under heating mode.
Timing unit 22, when by receiving the halt instruction under heating mode since halt instruction receiving unit 21 based on
When.
Outdoor fan control unit 23, for receiving the halt instruction under heating mode in halt instruction receiving unit 21
When, control outdoor fan power-off shuts down.
Compressor control unit 24, for after the timing time of timing unit 22 reaches the first setting time, control to be pressed
The power-off of contracting machine, shuts down.
Indoor fan control unit 25 is at least used for after the timing time of timing unit 22 reaches the second setting time,
Indoor fan power-off is controlled, is shut down.
Wherein, the second setting time is greater than the first setting time.
As another embodiment, for the air conditioner with four-way valve, stop control apparatus further includes four-way valve control
Unit processed, after reaching third setting time for the timing time in timing unit, control four-way valve power-off.Wherein, third is set
It fixes time greater than the first setting time and less than the second setting time.
Each structural unit in the stop control apparatus of the various embodiments described above runs certain software program, according to aforementioned institute
Corresponding halt control method executes the shutdown to air-conditioner with fixed frequency and controls.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although referring to aforementioned reality
Applying example, invention is explained in detail, for those of ordinary skill in the art, still can be to aforementioned implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these are modified or replace
It changes, the spirit and scope for claimed technical solution of the invention that it does not separate the essence of the corresponding technical solution.
