Specific embodiment
The preferred embodiment of the present invention described with reference to the accompanying drawings.It will be apparent to a skilled person that this
A little embodiments are used only for explaining technical principle of the invention, it is not intended that limit the scope of the invention.This field skill
Art personnel, which can according to need, makes adjustment to it, to adapt to specific application.For example, although be in specification with
When carrying out refrigerant recovering, it is described so that the pressure value in pipeline carries out judging whether the state in refrigerant recovering as an example,
But the present invention obviously can use the judgement of other forms, such as the coil temperature of indoor unit, coil temperature when usually freezing
Average value, the difference of the two freezes as long as this method can accurately distinguish out to determine whether be in the state of refrigerant recovering
The different conditions that mode and collection refrigerant mode are shown, by the state to determine whether to collect refrigerant mode.
With reference first to Fig. 1, the refrigerant recovering control method for air conditioner of the invention is described.Wherein, Fig. 1 is
The flow chart of control method of the invention.
As shown in Figure 1, for solve existing air conditioner can not temperature is lower indoors when carry out forced refrigeration, Wu Fashou
Collect refrigerant problem, control method of the invention includes:
S100, indoor environment temperature is obtained.
Indoor environment temperature is obtained by modes such as temperature sensors on air conditioner room unit first.
When S200, indoors environment temperature are not more than the first set temperature, the first offset is increased to indoor environment temperature
And it is stored as indoor environment compensation temperature.
If indoor environment temperature is not more than the first set temperature, illustrating that air conditioner has had been started up at this time prevents user from missing
The protected mode of operation, i.e., maintenance personal can not enter refrigeration mode at this time, in order to eliminate such case, through the invention
Control method one offset is increased to indoor environment temperature, keep collected temperature higher than actual temperature, and then release anti-
The only protected mode of user misoperation.
S300, indoors ambient compensation temperature be greater than the first set temperature when, control air conditioner operation refrigeration mode so as to
Collect refrigerant.
If indoor environment compensation temperature is greater than the first set temperature, illustrate that air conditioner has relieved protection mould at this time
Formula, maintenance personal can enter refrigeration mode, so that operator can easily collect refrigerant, avoid release refrigerant again
The operation of coolant adding, protects environment, also saves customer charge, shortens the maintenance time of maintenance personal, reduces dimension
Repair difficulty.
Further below referring to Fig. 2, the refrigerant recovering control method for air conditioner of the invention is described in detail.
As shown in Fig. 2, the refrigerant recovering control method for air conditioner is as follows in a kind of possible embodiment:
First detect present mode → when detect present mode be refrigerant recovering mode when, obtain outdoor environment temperature →
When outdoor environment temperature is not more than the second set temperature, the second offset is increased to outdoor environment temperature and is stored as outdoor ring
Border compensation temperature → when compensated outdoor environment compensation temperature is greater than the second set temperature, acquisition indoor environment temperature → when
When indoor environment temperature is not more than the first set temperature, the first offset is increased to indoor environment temperature and is stored as indoor environment
Compensation temperature → and when compensated indoor environment compensation temperature is greater than the first set temperature, control air conditioner runs refrigeration mode
The blower antiport of → control indoor unit.
The advantages of above-mentioned set-up mode, is:
Advantage one: by increasing the step of detecting present mode, judge that current air conditioner is to be in refrigerant recovering mode also
It is that if it is refrigerant recovering mode is in, then can operate normally down-stream in normal refrigerating mode, enable maintenance personal
Enough implement forced refrigeration, if it is normal refrigerating mode is in, the program of subsequent compensation will not run, user also cannot be strong
System refrigeration, ensure that user will not maloperation.
It should be noted that judging whether that the parameter in refrigerant recovering mode has much herein, it is not limited to enumerate
Example, when be in refrigerant recovering state when, coolant loop can be closed, refrigerant can be constantly gathered in outdoor unit at this time, complete
At refrigerant recovering, at this point, having the physical features much distinguished with normal refrigerating mode since refrigerant can not be completed to recycle
Show, such as in coolant loop, the pressure difference value of compressor two sides can be big than usual, is passed back at this time by pressure sensor
Data can determine whether in refrigerant recovering state；For another example refrigerant is completed to recycle always due to not having, the coil pipe temperature of indoor unit
Degree will become closer to room temperature, can not freeze always, also may determine that by the difference of the temperature sensor on coil pipe
It is refrigerant recovering mode or normal refrigerating mode.
Advantage two: if outdoor temperature is too low, air-conditioning also will start self judgment function, and confirmation air conditioner is in cold work
Under condition, in order to avoid maloperation, refrigeration mode can also be closed, it is therefore, increase when outdoor environment temperature is set no more than second more
When determining temperature, the second offset is increased for outdoor environment temperature, obtains outdoor environment temperature compensation, when outdoor environment temperature is mended
When repaying greater than the second setting value, next step operation is carried out.It is identical as the compensation way of indoor environment, enable air conditioner to force to transport
Row refrigeration mode collects refrigerant, avoids equally being unable to run refrigeration mode, and then can not collect cold since outdoor temperature is too low
The case where matchmaker.
Advantage three: making the blower antiport of indoor unit, thus prevent the cold wind after indoor mechanism cold from being blown into interior, and
It is that outdoor is partly refluxed to by air pipeline, so that room temperature fall is smaller, ensures that user is warm within doors in this way
Degree improves the experience of user when collecting refrigerant.Also, even if blower reversion also makes cold air part flow into interior, and
Enter from the air inlet of air conditioner, the air inlet of usual air conditioner is arranged at top, directly against user, therefore also just not
It will appear and directly blow to user, the situation for keeping user's body-sensing colder.
Further, as shown in Fig. 2, in a kind of possible embodiment, the refrigerant recovering for air conditioner is controlled
Method further include:
When compensated outdoor environment compensation temperature is still not more than the second set temperature, outdoor environment is compensated again
Temperature carry out the second setting value compensation, until its be greater than the second set temperature, it is ensured that can with force start refrigeration mode,
Similarly, when compensated indoor environment compensation temperature is still not more than the first set temperature, repeatedly increased it
One offset, until it is greater than the first set temperature.
If outdoor environment temperature is greater than the second set temperature, prove that its outdoor environmental conditions meets the item of conventional refrigerant
Part can directly acquire indoor environment temperature without compensation.Similarly, if indoor environment temperature is greater than the first set temperature,
Then prove that its indoor environmental condition meets the condition of conventional refrigerant, can without compensation, be directly entered refrigeration mode, start into
Row refrigerant recovering.
The advantages of above-mentioned set-up mode, is: when the first offset of setting and smaller the second offset, or it is extraneous
When temperature and set temperature gap are excessive, if preset value still cannot be reached after compensation, just need to recycle compensation at this time, prevent
Compensated value is still not up to setting value, and prevents the case where algorithm is from continuing.
Further, the first set temperature is 16 DEG C, and the first offset is 30 DEG C, and the second set temperature is -5 DEG C, the
Two offsets are 30 DEG C, and certain set temperature and compensation temperature are adjustable, and the set temperature of each manufacturer is different,
Offset can also correspondingly change, such as the first set temperature can also be 14 DEG C, and 18 DEG C etc., the second set temperature can be with
It is 0 DEG C, 10 DEG C etc., the first offset can be 10 DEG C, and 8 DEG C etc., the second offset can be 13 DEG C, 15 DEG C etc..
It particularly, can also be of the invention first in order to further prevent user misoperation to enter refrigerant recovering mode
Step: increase by a step before " obtaining indoor environment temperature " and " send refrigerant recovering instruction, control air conditioner enters refrigerant recovering mould
Formula ", the mode for sending instruction can be the Macintosh pressed on air conditioner remote controler, by increase Macintosh, and not to
Mode disclosed in family rests in the method only in maintenance personal's hand of profession, and when needing to run, operating air conditioner device forces system
It is cold, user misoperation can be prevented.Certainly, mode is varied, not necessarily Macintosh, can also be inside indoor unit
A key, the button that user cannot touch will not enumerate herein.
In conclusion by being compensated to room temperature, solve existing air conditioner can not indoors temperature it is lower
Shi Jinhang forced refrigeration, the problem of refrigerant can not be collected.Although the second setting value of outdoor temperature is generally lower, to make outdoor
Temperature generally all meets the requirements, and still, by compensating to outdoor temperature, further avoids air-conditioning due to outdoor temperature too
It is low, the second setting value cannot be reached, and then be unable to the special circumstances of forced refrigeration.By the step for increasing two circulation compensation
Suddenly, it is still not able to meet the first setting value or the second setting value after avoiding single compensation, causes method that cannot continue to execute
The case where occur.Blower reversely rotates so that cold air enters the room reductions, slows down the case where room temperature declines.Increase refrigerant
The judgement order of take-back model, and increase and send refrigerant recovering instruction, and the instruction is not easy to be touched by user, avoids
The maloperation of user causes room temperature opposite with desired value.
It should be noted that above embodiment be used merely to illustrate the principle of the present invention, it is not intended that with limit this hair
Bright protection scope, under conditions of without departing from the principle of the invention, those skilled in the art can be adjusted above structure,
So that the present invention can be applied to more specifical application scenarios.
