Description of the drawings
Fig. 1 is the flow chart based on fixed frequency air conditioner control method one embodiment of the present invention.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below with reference to drawings and Examples,
The present invention is described in further detail.
Fig. 1 is referred to, the figure show the flow chart based on fixed frequency air conditioner control method one embodiment of the present invention.
As shown in figure 1, the embodiment realize fixed frequency air conditioner control, specifically realize to start/stop of compressor control mistake
Journey is as follows：
Step 101：Operation of air conditioner, obtains current indoor temperature and current indoor coil temperature, compares current indoor temperature and works as
Front design temperature.
Current indoor temperature to be referred to and adopt the real-time Indoor Temperature accessed by frequency by temperature detection means, according to setting
Degree.For example, the Indoor Temperature obtained by the temperature sensor of machine air inlet is disposed in the interior by indoor temperature transmitter, for example
Degree.Indoor coil pipe refer to by temperature detection means, according to setting using it is accessed by frequency, on indoor set heat exchanger
Real-time coil temperature.Current design temperature refers to the current target temperature of operation of air conditioner, usually, is that user passes through remote control
Or set by control terminal expects the target temperature reached by interior, can easily be got by air-conditioner controller
Temperature.During operation of air conditioner, current indoor temperature and current indoor coil temperature are obtained in real time, and by current indoor
Temperature is made comparisons with current design temperature, specifically, is the size for comparing current indoor temperature and current design temperature.
Step 102：Compressor indoor temperature under is met with the comparative result of current design temperature in current indoor temperature
During the condition that shuts down, then compare current indoor coil temperature with current coil pipe target temperature.
The Rule of judgment that the compressor condition of shutting down under indoor temperature is known, prestored, if room
Interior temperature meets the condition, shows that can control compressor shuts down.Also, whether indoor temperature meets the condition,
Determined according to the comparative result of current indoor temperature and current design temperature.
Compressor indoor temperature under is met with the comparative result of current design temperature in judgement current indoor temperature to stop
Only during operating condition, then compare current indoor coil temperature with current coil pipe target temperature.Wherein, current coil pipe target temperature is
A known temperature value, and be a temperature value according to determined by current design temperature.Concrete determination mode may be referred to
Description below.
Step 103：Judge whether current indoor coil temperature and the comparative result of current coil pipe target temperature meet coil pipe
At a temperature of compressor shut down condition.If so, execution step 104；Otherwise, execution step 105.
The Rule of judgment that the compressor condition of shutting down under coil temperature is known, prestored, if room
Inner coil pipe temperature meets the condition, shows that can control compressor shuts down.Also, whether indoor coil pipe meets this
Condition, will determine according to the comparative result of current indoor coil temperature and current coil pipe target temperature.
Step 104：Control compressor shuts down.
If step 103 judges that current indoor coil temperature meets coil pipe with the comparative result of current coil pipe target temperature
At a temperature of compressor shut down condition, then control compressor and shut down.
Step 105：Control compressor keeps operating.
If step 103 judges that current indoor coil temperature is unsatisfactory for coil pipe with the comparative result of current coil pipe target temperature
At a temperature of compressor shut down condition, then control compressor and keep operating condition and do not stop.
Using the method for above-described embodiment, by introducing what whether indoor coil pipe shut down as control compressor
Condition, indoors temperature meet compressor shut down condition when, and non-controlling compressor directly shuts down, but ties again
Close indoor coil pipe to determine whether.If indoor coil pipe is unsatisfactory for the condition that compressor shuts down, control
Compressor keeps operating.So as to reducing the stop frequency of compressor to a certain extent, reducing because of high frequent start and stop
Cause the problem that fluctuations in indoor temperature is big.Also, it is used as control parameter by introducing indoor coil pipe, coil pipe temperature can be utilized
Impact of the degree to indoor temperature reduces indoor temperature because compressor shuts down relative to design temperature stablizing indoor temperature
The speed for rising or falling, further reduces the fluctuation of indoor temperature, improves the comfort of fixed frequency air conditioner.
In the above-described embodiments, if it is decided that current indoor temperature is unsatisfactory for interior with the comparative result of current design temperature
At a temperature of compressor shut down condition, show that indoor temperature is also not up to design temperature, then also control compressor and keep fortune
Turn state so that indoor temperature is approached to design temperature.
And, the compressor under indoor temperature shuts down condition, including but not limited to：Current indoor temperature is equal to works as
Front design temperature.In addition, the compressor condition of shutting down under indoor temperature can also be current indoor temperature with it is current
The difference of design temperature is less than certain difference, namely current indoor temperature is in close proximity to current design temperature.
Compressor under coil temperature shuts down condition, including but not limited to：Current indoor coil temperature is equal to works as
Front coil pipe target temperature.In addition, the compressor condition of shutting down under coil temperature can also be current indoor coil pipe temperature
Degree is less than certain difference with the difference of current coil pipe target temperature, namely current indoor coil temperature is in close proximity to current coil pipe mesh
Mark temperature.
To avoid because of compressor continuous running under the conditions of indoor temperature meets compressor shutdown causing indoor temperature to deviate
The waste of design temperature is larger and affects indoor temperature to adjust comfortableness and meaningless energy consumption, if in step 105 because judging to work as
The compressor that the comparative result of front indoor coil pipe and current coil pipe target temperature is unsatisfactory under coil temperature shuts down bar
Part, and control compressor keep operating condition during, continue to obtain current indoor temperature, and by current indoor temperature with
Force compressor shut down condition make judge.The condition if it is determined that current indoor temperature satisfaction pressure compressor shuts down
When, also control compressor and shut down.Compressor is forced to shut down condition by setting up, even if indoor coil target temperature is not
Meet the compressor under coil temperature to shut down condition, also force compressor to shut down.
As preferred embodiment, force compressor to shut down condition, at least include：
Operation of air conditioner refrigeration mode, current design temperature are more than the setting temperature difference with the difference of current indoor temperature；And operation of air conditioner
Heating mode, current indoor temperature are more than the setting temperature difference with the difference of current design temperature.For example, the temperature difference is set as 2 DEG C, then,
If under refrigeration mode, the difference of current design temperature and current indoor temperature more than 2 DEG C, namely current indoor temperature less than current
2 DEG C of design temperature, even if current indoor coil temperature also shuts down condition less than the compressor at a temperature of pedal disk pipe, also controls
Compressor shuts down, it is to avoid compressor continuous running and to cause indoor temperature to deviate design temperature excessive and cause uncomfortable.
And if under heating mode, current indoor temperature is more than 2 DEG C with the difference of current design temperature, namely current indoor temperature is higher than to work as
2 DEG C of front design temperature, even if current indoor coil temperature also shuts down condition less than the compressor at a temperature of pedal disk pipe, also controls
Compressor processed shuts down.
The condition it is furthermore preferred that pressure compressor shuts down, also includes：
When the difference of operation of air conditioner refrigeration mode, current design temperature and current indoor temperature is more than the setting temperature difference and persistently sets
Between；And operation of air conditioner heating mode, current indoor temperature and current design temperature difference is more than the setting temperature difference and persistently sets
Time.By arranging lasting setting time, it is more than the setting temperature difference in temperature difference and the duration reaches the feelings of setting time
Under condition, forced stoppage process is remake, it is to avoid cause compressor inaccurately to stop by force because of the of short duration mutation of indoor temperature.For example,
Setting time is 10min, sets the temperature difference as 2 DEG C.So, if under refrigeration mode, current design temperature and current indoor temperature
Difference more than 2 DEG C, and continue for 10min, if current indoor coil temperature also stops less than the compressor at a temperature of pedal disk pipe
Operating condition, also controls compressor and shuts down；If under heating mode, current indoor temperature is big with the difference of current design temperature
In 2 DEG C, and continue for 10min, if current indoor coil temperature also shuts down bar less than the compressor at a temperature of pedal disk pipe
Part, also controls compressor and shuts down.
Current coil pipe target temperature is determined according to current design temperature, is specifically included：
Operation of air conditioner refrigeration mode, obtains in the corresponding relation of design temperature and coil pipe target temperature under known, refrigeration mode
Coil pipe target temperature corresponding with current design temperature is taken, as current coil pipe target temperature；Or
Operation of air conditioner heating mode, obtains in the corresponding relation of design temperature and coil pipe target temperature under known, heating mode
Coil pipe target temperature corresponding with current design temperature is taken, as current coil pipe target temperature.
For example, the memory storage in air-conditioning control panel has two tables, is design temperature and disk under refrigeration mode respectively
The corresponding table of the design temperature under the corresponding table of pipe target temperature and heating mode and coil pipe target temperature, such that it is able to pass through to look into
The mode of correspondence table gets current coil pipe target temperature corresponding under different current design temperatures.
Air conditioner type is different, territory of use and use the dispar factor of room area, can cause to reach same settings temperature
In the case of degree, corresponding coil temperature there is also difference.To improve the accuracy of control, it is preferred to use air conditioner user is participated in
Form the corresponding relation of design temperature and coil pipe target temperature.
Specifically, user participates in the corresponding relation to form design temperature and coil pipe target temperature, can with but be not limited to
Using following two ways：
First, design temperature passes through following Procedure Acquisitions with the corresponding relation of coil pipe target temperature under refrigeration mode：
Power-on of air conditioner, into coil pipe target temperature Setting pattern, using active user's design temperature as target temperature refrigerating operaton,
Obtain current indoor temperature.Coil pipe target temperature Setting pattern can be started by special instruction；Or, give tacit consent to first in air-conditioning
The pattern is entered after establishing machine on secondary by cable.And, into after the pattern, user input design temperature is pointed out, and, point out setting
The set-up mode of temperature, for example, points out the design temperature of user input to be up to 30 DEG C, minimum 16 DEG C.Also, refrigerating operaton
Using high wind speed pattern.In running, current indoor temperature is obtained in real time.
Current indoor temperature is made comparisons with active user's design temperature, the compression in the case where comparative result meets indoor temperature
Machine shut down condition when, obtain indoor coil pipe now.
Indoor coil pipe now is reduced the temperature after design temperature as corresponding with active user's design temperature
Coil pipe target temperature, stores active user's design temperature coil pipe target temperature corresponding with active user's design temperature and two warm
The corresponding relation of degree.For example, active user's design temperature is 27 DEG C, and design temperature is 2 DEG C, in current indoor temperature and current use
The comparative result of family design temperature meet the compressor under indoor temperature shut down condition when indoor coil pipe be 15 DEG C,
With the coil pipe target temperature corresponding to 27 DEG C of user's design temperature it is then（15℃-2℃）=13℃.Then, store 27 DEG C of use
The corresponding relation of the coil pipe target temperature of family design temperature and 13 DEG C.
Then, change active user's design temperature, the above-mentioned process of repetition obtains multiple user's design temperatures and coil pipe mesh
The corresponding relation of mark temperature is simultaneously stored, and multiple temperature extremely corresponding relation forms design temperature and coil pipe target temperature under refrigeration mode
The corresponding relation of degree.
Same method, under the heating mode, the corresponding relation of design temperature and coil pipe target temperature is by following processes
Obtain：
Power-on of air conditioner, into coil pipe target temperature Setting pattern, using active user's design temperature as target temperature heating operation,
Obtain current indoor temperature.
Current indoor temperature is made comparisons with active user's design temperature, the compression in the case where comparative result meets indoor temperature
Machine shut down condition when, obtain indoor coil pipe now.
Indoor coil pipe now is raised the temperature after design temperature as corresponding with active user's design temperature
Coil pipe target temperature, stores active user's design temperature coil pipe target temperature corresponding with active user's design temperature and two warm
The corresponding relation of degree.For example, active user's design temperature is 22 DEG C, and design temperature is 2 DEG C, in current indoor temperature and current use
The comparative result of family design temperature meet the compressor under indoor temperature shut down condition when indoor coil pipe be 40 DEG C,
With the coil pipe target temperature corresponding to 22 DEG C of user's design temperature it is then（40℃+2℃）=42℃.Then, store 22 DEG C of use
The corresponding relation of the coil pipe target temperature of family design temperature and 42 DEG C.
Change active user's design temperature, the above-mentioned process of repetition obtains multiple user's design temperatures and coil pipe target temperature
The corresponding relation of degree is simultaneously stored, and multiple temperature extremely corresponding relation forms design temperature and coil pipe target temperature under heating mode
Corresponding relation.
The corresponding relation of design temperature and coil pipe target temperature is obtained using said method, although can accomplish to greatest extent
User's participation, but, complex operation.So, can also be obtained using the following second way：
Second, design temperature passes through following Procedure Acquisitions with the corresponding relation of coil pipe target temperature under refrigeration mode：
Power-on of air conditioner, into coil pipe target temperature Setting pattern, using active user's design temperature as target temperature refrigerating operaton,
Obtain current indoor temperature.

Machine shut down condition when, obtain indoor coil pipe now.
Indoor coil pipe now is reduced the temperature after design temperature as corresponding with active user's design temperature
Currently practical coil pipe target temperature.The description implemented referring to above-mentioned first kind of way of the process.
Then, obtain and work as in the corresponding relation from design temperature under known refrigeration mode with benchmark coil pipe target temperature
Benchmark coil pipe target temperature corresponding to front user's design temperature calculates current base disk as current base coil pipe target temperature
The difference of pipe target temperature and currently practical coil pipe target temperature, as the adjustment temperature difference.
By all benchmark coil pipe targets in corresponding relation of the design temperature under refrigeration mode with benchmark coil pipe target temperature
Temperature is updated to the difference of benchmark coil pipe target temperature and the adjustment temperature difference, formed under the refrigeration mode that actually calls design temperature with
The corresponding relation of coil pipe target temperature.
Wherein, before under refrigeration mode, the corresponding relation of design temperature and benchmark coil pipe target temperature usually air-conditioning dispatches from the factory
Jing programmings can carry out relatively reasonable accurate correspondence with reference to air conditioner type to accumulator for air conditioner.But, it is impossible to adapting to difference makes
With environment and room area size.Therefore, when air-conditioning is entered in user family, using coil pipe target temperature Setting pattern, by
User sets a design temperature, gets the actual corresponding coil pipe target temperature of design temperature institute, as currently practical disk
Pipe target temperature.Then, by it is being given in memory, with the current base coil pipe target temperature under design temperature with it is currently practical
The general benchmark coil pipe target temperature that the difference of coil pipe target temperature is given as memory with consider practical service environment, make
With the corrected value of the actual coil pipe target temperature of the factors such as room area, with the benchmark coil pipe target that this corrected value is given to storage
Temperature is corrected, the design temperature actually called in obtaining actual control process and the corresponding relation of coil pipe target temperature.Adopt
With the method, it is only necessary to which user runs few design temperature, such as 1 design temperature or 2 design temperatures, operation letter
It is single.
Likewise, design temperature passes through following Procedure Acquisitions with the corresponding relation of coil pipe target temperature under heating mode：
Power-on of air conditioner, into coil pipe target temperature Setting pattern, using active user's design temperature as target temperature heating operation,
Obtain current indoor temperature.
Current indoor temperature is made comparisons with active user's design temperature, the compression in the case where comparative result meets indoor temperature
Machine shut down condition when, obtain indoor coil pipe now.
Indoor coil pipe now is raised the temperature after design temperature as corresponding with active user's design temperature
Currently practical coil pipe target temperature.
From corresponding relation of the design temperature under known heating mode with benchmark coil pipe target temperature obtain and currently use
Benchmark coil pipe target temperature corresponding to the design temperature of family calculates current base coil pipe mesh as current base coil pipe target temperature
The difference of temperature and currently practical coil pipe target temperature is marked, as the adjustment temperature difference.
By all benchmark coil pipe targets in corresponding relation of the design temperature under heating mode with benchmark coil pipe target temperature
Temperature is updated to the difference of benchmark coil pipe target temperature and the adjustment temperature difference, formed under the heating mode that actually calls design temperature with
The corresponding relation of coil pipe target temperature.
No matter when carrying out coil pipe target temperature using any one in above two mode and determining, for same user sets
Constant temperature degree, can run repeatedly and obtain multiple coil pipe target temperatures, finally using the mean value of multiple coil pipe target temperatures as
The coil pipe target temperature corresponding to user's design temperature.
Above example is only illustrating technical scheme, rather than is limited；Although with reference to aforementioned reality
Apply example to be described in detail the present invention, for the person of ordinary skill of the art, still can be to aforementioned enforcement
