Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details. At this, the exemplary embodiment of the present invention and explanation thereof are used for explaining the present invention, but not as a limitation of the invention.
Consider that split frequency changer is under ultralow temperature heating condition, it may appear that outer machine frosting situation, thus causing outer machine evaporating temperature to reduce and relatively early entering defrost pattern. So there is following two problem:
1) outer machine frosting is very fast thus affecting heat exchange;
2) time entering defrost is too fast, thus affecting comfortableness.
But, it is clearly irrational to the time before extending into defrost from being lowered into the pipe temperature mode of defrost condition merely, because at that time outer machine has had more frost, heat exchange amount is poor.
Inventor contemplates that, electric expansion valve is as a kind of electronic type shaping modes, and Main Function is exactly the liquid supply rate regulating vaporizer according to pre-set programs. Therefore, it can improve the air-conditioning continuous operating time when worst cold case by being controlled the aperture of electric expansion valve trying one's best, the problem that off-premises station frosting is excessively serious can be avoided again.
Specifically, provide the air conditioning control method under a kind of heating mode in this example, as it is shown in figure 1, comprise the following steps:
Step 101: when air-conditioning is in heating mode, whether the outer tube temperature of detection air-conditioning is reduced to early warning temperature;
Above-mentioned early warning temperature, thresholding is triggered, specifically, it is possible to early warning temperature is set in such a way: obtain air-conditioning and trigger the outer tube temperature entering defrost pattern primarily as one, by triggering the numerical value obtained after the outer tube temperature entering defrost pattern increases predetermined temperature value, as early warning temperature.
Wherein, predetermined temperature value can in 1 DEG C to 3 DEG C value, predetermined temperature value being set in 1 DEG C to 3 DEG C, mainly considering, if taking too big value, the air-conditioning operation time under efficiency optimum condition to be had a strong impact on.
The outer tube temperature of air-conditioning can by outer machine pipe temperature bulb senses.
Step 102: if being reduced to described early warning temperature, then the aperture of the electric expansion valve being connected with vaporizer in described air-conditioning is adjusted.
Specifically, the aperture of electric expansion valve is adjusted, the aperture of the main aperture increasing electric expansion valve exactly and minimizing electric expansion valve, and switches between increasing and reducing, for example, it is possible to using the duration of default single defrost aperture transformation period as the cycle; When radix the cycle, it is gradually increased the aperture of electric expansion valve according to predetermined speed; When the even number cycle, being gradually reduced the aperture of electric expansion valve according to predetermined speed, until meeting pre-conditioned, stopping the adjustment to electronic expansion valve opening.
For example, it is possible to be controlled in such a way:
1) T is worked asOuter tube=TEarly warningTime, electric expansion valve is opened greatly gradually by pre-set velocity;
2) assume that electric expansion valve opens the single cycle time of automatic regulation function, i.e. defrost aperture transformation period is TTime, work as TTime=TI becomesTime, electric expansion valve is gradually reduced according still further to 10B/30S speed.
3) T is worked asTime=2TI becomesTime, electric expansion valve continues to be gradually increased by pre-set velocity, by that analogy, until meeting exit criteria.
Above-mentioned exit criteria may is that and receives the instruction stopping that the aperture of electric expansion valve is adjusted, or, the time that the aperture of electric expansion valve is adjusted reaches the total duration preset, namely, artificial Non-follow control exits this program as required, or reach the end time set in advance, for instance: TTime=nTI becomes, then this program is exited.
Wherein, the duration of single defrost aperture transformation period can in 5 minutes to 10 minutes value, predetermined speed can be every 30S aperture changing 10 steps, this mainly considers if changing too fast, reducing efficiency, if changing slow, pipe temperature is likely to more difficult improve in a short time, thus causing that outer tube temperature remains reduction, so that entering defrost pattern.
In upper example, when air-conditioning is in heating mode, particularly in when carrying out heating operation under worst cold case, pre-set an early warning temperature, after the outer tube temperature drop of detection air-conditioning is low to moderate early warning temperature, just it is adjusted improving outer tube temperature to the aperture of electric expansion valve, to avoid air-conditioning to frequently enter defrost pattern, solve air-conditioning in prior art by the way long lasting for the technical problem of heating operation, effective lifting air-conditioning to have been reached under worst cold case, continued the technique effect of heating operation time under worst cold case.
Below in conjunction with a specific embodiment, above-mentioned air conditioning control method is illustrated, it is important to note, however, that this specific embodiment is merely to be better described the present invention, be not intended that inappropriate limitation of the present invention.
By introducing early warning temperature (can value be: TDefrost outer tube temperature+TStay) ensure that air conditioning system is before entering defrost, it is possible to there is sufficiently long Timing electronic expansion valve opening to ensure to extend the time that low temperature runs continuously. Then, evaporating temperature is improved so that proper extension air-conditioning continuous heating under worst cold case runs the time by controlling the mode of electronic expansion valve opening change, further, can also ensure that evaporating temperature will not raise always, can change regularly within the scope of one, in order to ensure that air-conditioner can run in the scope that efficiency is higher.
Considering that general split frequency changer heats logic is control outer machine evaporating temperature lower than after certain preset value, and namely operation a few minutes can enter defrost pattern continuously, and wherein, evaporating temperature generally takes outer tube temperature.
Wherein, TStayCan value be 1 DEG C, T can be adjusted according to different type of machinesStayValue, but be generally no greater than 3 DEG C, this mainly considers if TStayTake too big value, the air-conditioning operation time under efficiency optimum condition can be had a strong impact on.
The adjustment of electric expansion valve is typically all calculates by " step ", such as, electric expansion valve range of accommodation is generally: 120B to 480B, and the adjustment structure of electric expansion valve is a motor, and the minimum angles scope that motor rotates is called a step (1B).
Electric expansion valve be automatically adjusted speed reference can with every 30S change 10B aperture velocity variations, if changing too fast, efficiency can be reduced, if changing slow, pipe temperature is likely to more difficult improve in a short time, thus causing that outer tube temperature remains reduction, so that entering defrost pattern.
Defrost aperture transformation period TI becomesCan according to practical situation value, for instance, it is possible to take 5min according to experimental test, generally, TI becomesValue less than 10min, so can ensure that the process that expansion valve opening regulates is effective rapidly.
Wherein, aperture reference value is on extending the opening value in defrost pattern system at that moment, carries out aperture regular lifting in time in program as benchmark.
Specifically, it is possible to arranging a pattern extending the continuous heating operation time for air-conditioning, this pattern is different from conventional low-temperature heating pattern, it is possible to is when user triggers, just can enter this pattern.
After starting this control model, whether detection outer tube temperature reaches early warning temperature, specifically, it is possible to detection in such a way: gather the outer machine pipe warming thermometer bulb temperature of model machine, obtain TOuter tube, work as TOuter tube=TEarly warningTime, open this program and aperture is temporally automatically controlled.
Can be controlled in such a way:
1) T is worked asOuter tube=TEarly warningTime, electric expansion valve is opened greatly gradually by pre-set velocity, for instance: 10B/30S;
2) assume that electric expansion valve opens the single cycle time of automatic regulation function, i.e. defrost aperture transformation period is TTime, work as TTime=TI becomesTime, electric expansion valve is gradually reduced according still further to 10B/30S speed.
3) T is worked asTime=2TI becomesTime, electric expansion valve continues to be gradually increased by 10B/30S speed, by that analogy, until artificial Non-follow control exits this program as required, or reaches the end time set in advance: TTime=nTI becomes, then this program is exited.
Namely, in upper example, mainly the aperture according to electric expansion valve is more big, outer tube temperature is more high, and (aperture tunes up, evaporating pressure improve, outer tube temperature improve, heat outer tube temperature and be approximately equal to evaporating temperature) principle, therefore, outer tube temperature can be made will not to be quickly reduced to the outer tube temperature T entering defrost by the aperture of adjustment electric expansion valveDefrost outer tube temperature, thus the continuous operating time before extending into defrost, in order to improve comfortableness during air-conditioning heating pattern. Further, if electronic expansion valve opening automatic adjustment height always, and do not reduce, just influence whether the efficiency of air-conditioning current working. Therefore, in this example be adjust electric expansion valve aperture a decay will not be excessive aperture interval in change.
The air conditioning control method provided in upper example, is primarily directed to what frequency conversion separating air conditioner low-temperature heating was controlled, is primarily directed to those under some operating mode, the ability bigger type of decay, only small need not use this pattern if decayed. Specifically, it is possible to automatically control expansion valve opening and make evaporating temperature change in a relatively reasonable scope, both ensured that will not quickly reach outer tube temperature protection value entered defrost, it is possible to alleviate frosting degree, in order to indirectly improve efficiency.
In upper example, involved design parameter is merely to be better described the present invention, in the process that reality performs, it is possible to according to being that the practical situation value to parameter is adjusted, this is not construed as limiting by the application. Such as, it is the aperture pace of change being referred to according to 1P to 2P air-conditioning that above-mentioned electric expansion valve opens big speed, if system is bigger than normal or efficiency grade is higher, aperture pace of change can be formulated according to system practical situation.
Can ensure that air-conditioning is entering before defrost pattern (machine frosting outside in other words more serious before) by the way, improve evaporating temperature to alleviate frosting symptom, extend low temperature continuous operating time, can ensure that model machine ability fluctuates in optimized scope simultaneously, solving domestic split frequency changer under low-temperature heating operating mode, the very fast comfortableness entering defrost and cause is deteriorated and the outer machine frosting that occurs under low temperature bad working environments is serious thus the problem that affects heat exchange amount.
