Detailed description of the invention
The attached drawing constituted part of this application is used to provide further understanding of the present invention, schematic reality of the invention
It applies example and its explanation is used to explain the present invention, do not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the air conditioning control method flow chart under heating mode according to an embodiment of the present invention；
Fig. 2 is the structural block diagram of the air conditioning control device under heating mode according to an embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right below with reference to embodiment and attached drawing
The present invention is described in further details.Here, exemplary embodiment and its explanation of the invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
In view of seperated frequency changer is under ultralow temperature heating condition, it may appear that outer machine frosting situation, so as to cause the steaming of outer machine
Sending out temperature reduces and relatively early enters defrost pattern.There are problems that following two in this way:
1) outer machine frosting is comparatively fast to influence to exchange heat；
2) too fast into the time of defrost, to influence comfort.
However, extending into the time before defrost from the tube temperature mode for being lowered into defrost condition merely is clearly not conform to
Reason, because at that time outer machine has had more frost, heat exchange amount is poor.
For inventor it is considered that electric expansion valve is as a kind of electronic type shaping modes, main function is exactly according to default journey
The liquid supply rate of sequence adjusting evaporator.Therefore, it can be controlled by the aperture to electric expansion valve to improve air-conditioning as far as possible and exist
Continuous operating time when worst cold case, and problem that can be excessively serious to avoid outdoor unit frosting.
Specifically, the air conditioning control method under a kind of heating mode is provided in this example, as shown in Figure 1, including following
Step:
Step 101: in the case where air-conditioning is in heating mode, whether the outer tube temperature for detecting air-conditioning is reduced to early warning temperature
Degree；
Primarily as a trigger threshold specifically, early warning can be arranged in above-mentioned early warning temperature in the following way
Temperature: obtaining the outer tube temperature that air-conditioning triggering enters defrost pattern, the outer tube temperature that triggering enters defrost pattern is increased predetermined
The numerical value obtained after temperature value, as early warning temperature.
Wherein, predetermined temperature value can in 1 DEG C to 3 DEG C value, set predetermined temperature value in 1 DEG C to 3 DEG C, mainly
It allows for if taking too big value, runing time of the air-conditioning under efficiency optimum condition can be seriously affected.
The outer tube temperature of air-conditioning can pass through outer machine tube temperature bulb senses.
Step 102: if being reduced to the early warning temperature, to the electric expansion valve being connected in the air-conditioning with evaporator
Aperture be adjusted.
Specifically, the aperture of electric expansion valve is adjusted, is mainly exactly the aperture and reduction for increasing electric expansion valve
The aperture of electric expansion valve, and switched between increase and reduction, for example, can be changed with preset single defrost aperture
The duration of time is as the period；At the radix period, the aperture of electric expansion valve is gradually increased according to predetermined speed；In even number
When a period, it is gradually reduced the aperture of electric expansion valve according to predetermined speed, until meeting preset condition, stops to electronic expansion
The adjustment of valve opening.
For example, it can be controlled in the following way:
1) work as TOuter tube=TEarly warningWhen, electric expansion valve is gradually opened greatly by pre-set velocity；
2) assume that electric expansion valve opens the signal period time of automatic regulation function, i.e. defrost aperture transformation period is
TWhen, work as TWhen=TI becomesWhen, electric expansion valve is gradually reduced according still further to 10B/30S speed.
3) work as TWhen=2TI becomesWhen, electric expansion valve continues to be gradually increased by pre-set velocity, and so on, it is exited until meeting
Condition.
Above-mentioned exit criteria may is that the instruction for receiving and stopping being adjusted to the aperture of electric expansion valve, alternatively, right
The time that the aperture of electric expansion valve is adjusted has reached preset total duration, that is, artificially manually controls and exits as required
The program, or reach the preset end time, such as: TWhen=nTI becomes, then the program is exited.
Wherein, the duration of single defrost aperture transformation period can value, predetermined speed can be in 5 minutes to 10 minutes
It is the aperture that every 30S changes 10 steps, this mainly considers that efficiency can be reduced if variation is too fast, if changing slow, tube temperature
It more difficult may improve in a short time, be still reduction so as to cause outer tube temperature, so that into defrost pattern.
In upper example, in the case where air-conditioning is in heating mode, heating operation is carried out especially under worst cold case
When, an early warning temperature is preset, after detecting the outer tube temperature drop of air-conditioning down to early warning temperature, just to electric expansion valve
Aperture is adjusted to improve outer tube temperature, frequently enters defrost pattern to avoid air-conditioning, solves existing skill through the above way
The technical issues of air-conditioning can not be long lasting for heating operation under worst cold case in art has reached effective promotion air-conditioning in low temperature
Continue the technical effect of heating operation time under operating condition.
Above-mentioned air conditioning control method is illustrated below with reference to a specific embodiment, it is important to note, however, that should
Specific embodiment does not constitute improper limitations of the present invention merely to the present invention is better described.
It (can be with value are as follows: T by introducing early warning temperatureThe outer tube temperature of defrost+TIt stays) guarantee that air-conditioning system, can be with before entering defrost
There is sufficiently long time adjustment electronic expansion valve opening to guarantee the time of extension low temperature continuous operation.Then, pass through control electricity
The mode of sub- expansion valve opening variation improves evaporating temperature so that continuous heating fortune of the air-conditioning under worst cold case is appropriately extended
The row time, further, it can also be ensured that evaporating temperature will not increase always, can regularly change within the scope of one,
To guarantee that air conditioner can be run in the higher range of efficiency.
In view of general seperated frequency changer heating logic is continuous operation after the outer machine evaporating temperature of control is lower than certain preset value
A few minutes can enter defrost pattern, wherein evaporating temperature generally takes outer tube temperature.
Wherein, TIt staysIt can be with value for 1 DEG C, according to the adjustable T of different type of machinesIt staysValue, but generally no greater than 3 DEG C,
This is mainly considered if TIt staysIf taking too big value, runing time of the air-conditioning under efficiency optimum condition can be seriously affected.
The adjusting of electric expansion valve is typically all to press " step " come what is calculated, for example, electric expansion valve adjustable range is general are as follows:
120B to 480B, the adjustment structure of electric expansion valve are a stepper motors, and the minimum angles range of stepper motor rotation is known as
One step (1B).
The automatic adjustment speed reference of electric expansion valve can change the velocity variations of 10B aperture with every 30S, if become
Change too fast, efficiency can be reduced, if changing slow, tube temperature more difficult may be improved in a short time, be still so as to cause outer tube temperature
It reduces, so that into defrost pattern.
Defrost aperture transformation period TI becomesCan value according to the actual situation, for example, 5min can be taken according to experimental test,
Under normal circumstances, TI becomesValue be no more than 10min, can guarantee in this way expansion valve opening adjust process it is effective rapidly.
Wherein, aperture a reference value is to open the opening value for extending defrost pattern at that moment in system, is come as benchmark
Carry out aperture regular lifting at any time in program.
Specifically, the mode of an extension continuous heating runing time can be set for air-conditioning, and the mode is low with routine
Warm heating mode is different, can be in the case where user's triggering, can just enter the mode.
After starting the control model, detect whether outer tube temperature reaches early warning temperature, it specifically, can be in the following way
Detection: the outer machine tube temperature temperature sensing package temperature of model machine is acquired, T is obtainedOuter tube, work as TOuter tube=TEarly warningWhen, open this program to aperture temporally
It carries out automatically controlling.
It can be controlled in the following way:
1) work as TOuter tube=TEarly warningWhen, electric expansion valve is gradually opened greatly by pre-set velocity, such as: 10B/30S；
2) assume that electric expansion valve opens the signal period time of automatic regulation function, i.e. defrost aperture transformation period is
TWhen, work as TWhen=TI becomesWhen, electric expansion valve is gradually reduced according still further to 10B/30S speed.
3) work as TWhen=2TI becomesWhen, electric expansion valve continues to be gradually increased by 10B/30S speed, and so on, until artificial
It manually controls and exits the program as required, or reach the preset end time: TWhen=nTI becomes, then the program is exited.
That is, mainly bigger according to the aperture of electric expansion valve, outer tube temperature is higher, and (aperture tunes up, and steams in upper example
Send out pressure to improve, outer tube temperature improves, and heats outer tube temperature and is approximately equal to evaporating temperature) principle, it is therefore, swollen by adjusting electronics
The aperture of swollen valve can make outer tube temperature not to be reduced to the outer tube temperature T into defrost quicklyThe outer tube temperature of defrost, to extend into defrost
Continuous operating time before, to improve comfort when air-conditioning heating mode.Further, if electronic expansion valve opening
Automatic adjustment height always just influences whether the efficiency of air-conditioning current working without reducing.It therefore, is that adjustment electronics is swollen in this example
The aperture of swollen valve changes in the aperture section that a decaying will not be excessive.
The air conditioning control method provided in upper example is controlled primarily directed to frequency conversion separating air conditioner low-temperature heating
, primarily directed to those under certain operating conditions, the biggish type of ability decaying, if decaying very little is not need to use this mould
Formula.Specifically, can automatically control expansion valve opening changes evaporating temperature in a relatively reasonable range, both guarantees
Outer tube temperature protection value will not be quickly reached and enter defrost, can be relieved frosting degree, also to improve efficiency indirectly.
In upper example, related design parameter is merely to be better described the present invention, during actually executing,
The value of parameter can be adjusted according to being actual conditions, the application is not construed as limiting this.For example, above-mentioned electric expansion valve
Opening big speed is the aperture pace of change that can refer to according to 1P to 2P air-conditioning, if system is bigger than normal or efficiency grade is higher, is opened
Degree pace of change can be formulated according to system actual conditions.
Can guarantee through the above way air-conditioning enter defrost pattern before (in other words outer machine frosting it is more serious it
Before), evaporating temperature is improved to alleviate frosting symptom, extends low temperature continuous operating time, while model machine ability can be guaranteed most
Fluctuation, solves household fission frequency changer under low-temperature heating operating condition in excellent range, comparatively fast enters comfort caused by defrost
The outer machine frosting occurred under variation and low temperature bad working environments is seriously thus the problem of influencing heat exchange amount.
