After a specific embodiment of the invention is read in conjunction with the figure, the other features and advantages of the invention will become more clear Chu.
Detailed description of the invention
Fig. 1 is the flow chart based on fixed frequency air conditioner control method 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 flow chart based on fixed frequency air conditioner control method one embodiment of the present invention.
As shown in Figure 1, the embodiment realizes fixed frequency air conditioner control, specifically realizes the mistake to start/stop of compressor control Journey is as follows:
Step 101: operation of air conditioner obtains current indoor temperature and current indoor coil temperature, compares current indoor temperature With current set temperature.
Current indoor temperature, which refers to, uses real-time Indoor Temperature accessed by frequency by temperature detection means, according to setting Degree.For example, the temperature sensor Indoor Temperature obtained for passing through indoor temperature transmitter, machine air inlet indoors being for example arranged Degree.Indoor coil pipe refers to be used accessed by frequency, on indoor set heat exchanger by temperature detection means, according to setting Real-time coil temperature.Current set temperature refers to that the current target temperature of operation of air conditioner is generally that user passes through remote controler Or the indoor target temperature achieved of an expectation set by controlling terminal, it 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 set temperature, is the size for comparing current indoor temperature Yu current set temperature specifically.
Step 102: meeting the compressor under room temperature in the comparison result of current indoor temperature and current set temperature When the condition that shuts down, then compare current indoor coil temperature and current coil pipe target temperature.
The compressor condition of shutting down under room temperature is a known, pre-stored Rule of judgment, if room Interior temperature meets the condition, shows that can control compressor shuts down.Also, whether room temperature meets the condition, It is determined according to the comparison result of current indoor temperature and current set temperature.
The compressor under room temperature is met in the comparison result for determining current indoor temperature and current set temperature to stop Only when operating condition, then compare current indoor coil temperature and 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 set temperature.Specific method of determination can refer to Subsequent description.
Step 103: judging whether current indoor coil temperature and the comparison result of current coil pipe target temperature meet coil pipe At a temperature of compressor shut down condition.If so, executing step 104;Otherwise, step 105 is executed.
The compressor condition of shutting down under coil temperature is a known, pre-stored Rule of judgment, 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 be determined according to the comparison result of current indoor coil temperature and current coil pipe target temperature.
Step 104: control compressor shuts down.
If step 103 determines that the comparison result of current indoor coil temperature and current coil pipe target temperature meets coil pipe At a temperature of compressor shut down condition, then control compressor and shut down.
Step 105: control compressor keeps operating.
If step 103 determines that the comparison result of current indoor coil temperature and current coil pipe target temperature is unsatisfactory for coil pipe At a temperature of compressor shut down condition, then control compressor and keep operating condition without stopping.
Using the method for above-described embodiment, whether shut down by introducing indoor coil pipe as control compressor Condition, indoors temperature meet compressor shut down condition when, and non-controlling compressor directly shuts down, but ties again It closes indoor coil pipe and makees further judgement.If indoor coil pipe is unsatisfactory for the condition that compressor shuts down, control Compressor keeps operating.To reduce the stop frequency of compressor to a certain extent, reduce because of high frequent start and stop Lead to the problem that fluctuations in indoor temperature is big.Also, by introducing indoor coil pipe as control parameter, coil pipe temperature can be utilized The influence to room temperature is spent to stablize room temperature, reduces room temperature due to compressor shuts down relative to set temperature The speed risen or fallen further decreases the fluctuation of room temperature, improves the comfort of fixed frequency air conditioner.
In the above-described embodiments, if it is decided that current indoor temperature and the comparison result of current set temperature are unsatisfactory for interior At a temperature of compressor shut down condition, show that room temperature is also not up to set temperature, then also control compressor keeps fortune Turn state, so that room temperature is approached to set temperature.
The condition moreover, compressor under room temperature shuts down, including but not limited to: current indoor temperature is equal to and works as Preceding set temperature.In addition to this, the compressor condition of shutting down under room temperature can also be current indoor temperature and current The difference of set temperature is less than some difference namely current indoor temperature is in close proximity to current set temperature.
Compressor under coil temperature shuts down condition, including but not limited to: current indoor coil temperature is equal to and works as Preceding coil pipe target temperature.In addition to this, the compressor condition of shutting down under coil temperature can also be current indoor coil pipe temperature The difference of degree and current coil pipe target temperature is less than some difference namely current indoor coil temperature is in close proximity to current coil pipe mesh Mark temperature.
To cause room temperature to deviate due to avoiding the compressor continuous running under the conditions of room temperature meets compressor shutdown Set temperature is larger and influences the waste of the comfort of room temperature adjusting and meaningless energy consumption, if in step 105 because judgement is worked as The compressor that the comparison result of preceding indoor coil pipe and current coil pipe target temperature is unsatisfactory under coil temperature shuts down item 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 work judge.The condition if it is determined that current indoor temperature satisfaction pressure compressor shuts down When, it also controls compressor and shuts down.Compressor is forced to shut down condition by adding, even if indoor coil target temperature is not Meet the compressor under coil temperature to shut down condition, also compressor is forced to shut down.
As preferred embodiment, forces compressor to shut down condition, includes at least:
The difference of operation of air conditioner refrigeration mode, current set temperature and current indoor temperature is greater than the setting temperature difference;And air-conditioning The difference of operation heating mode, current indoor temperature and current set temperature is greater than the setting temperature difference.For example, the temperature difference is set as 2 DEG C, that , if under refrigeration mode, the difference of current set temperature and current indoor temperature is greater than 2 DEG C namely current indoor temperature is lower than Current 2 DEG C of set temperature, the condition even if compressor under the also less than sufficient coil temperature of current indoor coil temperature shuts down, Control compressor shuts down, and avoids compressor continuous running and makes room temperature deviation set temperature excessive and cause not relax It is suitable.And if the difference of current indoor temperature and current set temperature is greater than 2 DEG C namely current indoor temperature is high under heating mode In 2 DEG C of current set temperature, the condition even if compressor under the also less than sufficient coil temperature of current indoor coil temperature shuts down, Also control compressor shuts down.
The condition it is furthermore preferred that pressure compressor shuts down, further includes:
The difference of operation of air conditioner refrigeration mode, current set temperature and current indoor temperature is greater than the setting temperature difference and continues to set Time;And operation of air conditioner heating mode, the difference of current indoor temperature and current set temperature are greater than the setting temperature difference and persistently set It fixes time.By the way that lasting setting time is arranged, it is greater than the setting temperature difference in temperature difference and the duration reaches setting time In the case of, forced stoppage processing is remake, avoids causing compressor inaccurately to stop by force because of the of short duration mutation of room temperature.Example Such as, setting time 10min sets the temperature difference as 2 DEG C.So, if under refrigeration mode, current set temperature and current indoor temperature The difference of degree is greater than 2 DEG C and continue for 10min, if the compressor under the also less than sufficient coil temperature of current indoor coil temperature stops Only operating condition also controls compressor and shuts down;If under heating mode, the difference of current indoor temperature and current set temperature Greater than 2 DEG C and it continue for 10min, if the compressor under the also less than sufficient coil temperature of current indoor coil temperature shuts down Condition also controls compressor and shuts down.
Current coil pipe target temperature is determined according to current set temperature, is specifically included:
Operation of air conditioner refrigeration mode, from known, set temperature and coil pipe target temperature under refrigeration mode corresponding relationship It is middle to obtain coil pipe target temperature corresponding with current set temperature, as current coil pipe target temperature;Or
Operation of air conditioner heating mode, from known, set temperature and coil pipe target temperature under heating mode corresponding relationship It is middle to obtain coil pipe target temperature corresponding with current set temperature, as current coil pipe target temperature.
For example, two tables are stored in the memory of air-conditioning control panel, are set temperature and disk under refrigeration mode respectively Set temperature under the correspondence table and heating mode of pipe target temperature and the corresponding table of coil pipe target temperature, so as to by looking into The mode of corresponding table gets current coil pipe target temperature corresponding under different current set temperatures.
Air conditioner type difference, territory of use and the use dispar factor of room area, can to reach same settings temperature There is also differences for corresponding coil temperature in the case where degree.For the accuracy for improving control, it is preferred to use air conditioner user participates in Form the corresponding relationship of set temperature and coil pipe target temperature.
Specifically, user participates in being formed the corresponding relationship of set temperature Yu coil pipe target temperature, can with but be not limited to Using following two ways:
First, set temperature and the corresponding relationship of coil pipe target temperature are obtained by following processes under refrigeration mode:
Power-on of air conditioner is freezed into coil pipe target temperature Setting pattern using active user's set temperature as target temperature Operation obtains current indoor temperature.Coil pipe target temperature Setting pattern can be started by special instruction;Alternatively, default exists Air-conditioning enters the mode after powering on booting for the first time.Moreover, prompting user to input set temperature, moreover, mentioning into after the mode Show the set-up mode of set temperature, for example, prompt user input set temperature be up to 30 DEG C, it is 16 DEG C minimum.Also, it makes Cold operation uses high wind speed mode.In the process of running, current indoor temperature is obtained in real time.
Current indoor temperature is made comparisons with active user's set temperature, the compression in the case where comparison result meets room temperature Machine shut down condition when, obtain indoor coil pipe at this time.
Temperature after indoor coil pipe at this time is reduced set temperature is as corresponding with active user's set temperature Coil pipe target temperature stores active user's set temperature coil pipe target temperature corresponding with active user's set temperature and two temperature The corresponding relationship of degree.For example, active user's set temperature is 27 DEG C, and set temperature is 2 DEG C, in current indoor temperature and current use The compressor that the comparison result of family set temperature meets under room temperature shut down condition when indoor coil pipe be 15 DEG C, Then coil pipe target temperature corresponding to user's set temperature with 27 DEG C is (15 DEG C -2 DEG C)=13 DEG C.Then, 27 DEG C of use is stored The corresponding relationship of family set temperature and 13 DEG C of coil pipe target temperature.
Then, change active user's set temperature, repeat above-mentioned process, obtain multiple user's set temperatures and coil pipe mesh The corresponding relationship of temperature and storage are marked, multiple temperature extremely corresponding relationship forms set temperature and coil pipe target temperature under refrigeration mode The corresponding relationship of degree.
Same method, the corresponding relationship of set temperature and coil pipe target temperature passes through following processes under the heating mode It obtains:
Power-on of air conditioner is heated into coil pipe target temperature Setting pattern using active user's set temperature as target temperature Operation obtains current indoor temperature.
Current indoor temperature is made comparisons with active user's set temperature, the compression in the case where comparison result meets room temperature Machine shut down condition when, obtain indoor coil pipe at this time.
Temperature after indoor coil pipe at this time is increased set temperature is as corresponding with active user's set temperature Coil pipe target temperature stores active user's set temperature coil pipe target temperature corresponding with active user's set temperature and two temperature The corresponding relationship of degree.For example, active user's set temperature is 22 DEG C, and set temperature is 2 DEG C, in current indoor temperature and current use The compressor that the comparison result of family set temperature meets under room temperature shut down condition when indoor coil pipe be 40 DEG C, Then coil pipe target temperature corresponding to user's set temperature with 22 DEG C is (40 DEG C+2 DEG C)=42 DEG C.Then, 22 DEG C of use is stored The corresponding relationship of family set temperature and 42 DEG C of coil pipe target temperature.
Change active user's set temperature, repeats above-mentioned process, obtain multiple user's set temperatures and coil pipe target temperature The corresponding relationship and storage, multiple temperature extremely corresponding relationship of degree form set temperature and coil pipe target temperature under heating mode Corresponding relationship.
The corresponding relationship of set temperature and coil pipe target temperature is obtained using the above method, although can accomplish to greatest extent User's participation, it is still, complicated for operation.So, it can also be obtained using the following second way:
Second, set temperature and the corresponding relationship of coil pipe target temperature are obtained by following processes under refrigeration mode:
Power-on of air conditioner is freezed into coil pipe target temperature Setting pattern using active user's set temperature as target temperature Operation obtains current indoor temperature.
Current indoor temperature is made comparisons with active user's set temperature, the compression in the case where comparison result meets room temperature Machine shut down condition when, obtain indoor coil pipe at this time.
Temperature after indoor coil pipe at this time is reduced set temperature is as corresponding with active user's set temperature Currently practical coil pipe target temperature.The specific implementation of the process referring to above-mentioned first way description.
Then, it obtains and works as from the corresponding relationship of set temperature under known refrigeration mode and benchmark coil pipe target temperature Benchmark coil pipe target temperature corresponding to preceding user's set 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 the corresponding relationship of set temperature under refrigeration mode and benchmark coil pipe target temperature Temperature is updated to benchmark coil pipe target temperature and adjusts the difference of the temperature difference, formed under the refrigeration mode that actually calls set temperature with The corresponding relationship of coil pipe target temperature.
Wherein, the corresponding relationship of set temperature and benchmark coil pipe target temperature is usually that air-conditioning factory is preceding under refrigeration mode Through programming to accumulator for air conditioner, relatively reasonable accurate correspondence can be carried out in conjunction with air conditioner type.But can not adapt to difference makes With environment and room area size.Therefore, when air-conditioning enters in user family, using coil pipe target temperature Setting pattern, by User sets a set temperature, the practical corresponding coil pipe target temperature of set temperature institute is got, as currently practical disk Pipe target temperature.Then, by it is being provided in memory, under set temperature current base coil pipe target temperature with it is currently practical The general benchmark coil pipe target temperature that the difference of coil pipe target temperature is provided as memory with consider practical service environment, make With the corrected value of the practical coil pipe target temperature of the factors such as room area, the benchmark coil pipe target that storage is provided with this corrected value Temperature corrects, and obtains the corresponding relationship of the set temperature and coil pipe target temperature actually called in practical control process.It adopts With this method, it is only necessary to which user runs few set temperature, such as 1 set temperature or 2 set temperatures, operation letter It is single.
Likewise, set temperature and the corresponding relationship of coil pipe target temperature are obtained by following processes under heating mode:
Power-on of air conditioner is heated into coil pipe target temperature Setting pattern using active user's set temperature as target temperature Operation obtains current indoor temperature.
Current indoor temperature is made comparisons with active user's set temperature, the compression in the case where comparison result meets room temperature Machine shut down condition when, obtain indoor coil pipe at this time.
Temperature after indoor coil pipe at this time is increased set temperature is as corresponding with active user's set temperature Currently practical coil pipe target temperature.
It is used from being obtained in the corresponding relationship of set temperature under known heating mode and benchmark coil pipe target temperature with current Benchmark coil pipe target temperature corresponding to the set temperature of family calculates current base coil pipe mesh as current base coil pipe target temperature The difference for marking temperature and currently practical coil pipe target temperature, as the adjustment temperature difference.
By all benchmark coil pipe targets in the corresponding relationship of set temperature under heating mode and benchmark coil pipe target temperature Temperature is updated to benchmark coil pipe target temperature and adjusts the difference of the temperature difference, formed under the heating mode that actually calls set temperature with The corresponding relationship of coil pipe target temperature.
When being determined regardless of carrying out coil pipe target temperature using any one of above two mode, the same user is set Determine temperature, can run repeatedly and obtain multiple coil pipe target temperatures, finally using the average value of multiple coil pipe target temperatures as Coil pipe target temperature corresponding to user's set temperature.
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.
