Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present inventionCase is clearly and completely described, and obviously, described embodiment is only one of the present inventionDivide embodiment, instead of whole embodiment. Based on the embodiment in the present invention, this area is generalLogical technical staff is not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of method of adjusting outdoor fan rotating speed, as shown in Figure 1,The method comprises:
Step 101, determine that whether air-conditioning is in cryogenic refrigeration pattern.
Wherein, determine whether air-conditioning comprises in cryogenic refrigeration pattern: determine outdoor environment temperatureWhether be less than the 3rd preset temperature, and whether outdoor coil pipe used temperature be less than the second preset temperature, andContinue the first default duration.
If outdoor environment temperature is less than described the 3rd preset temperature, and outdoor coil pipe used temperature is less thanTwo preset temperatures, and continue the first default duration, determine that air-conditioning is in cryogenic refrigeration pattern,Continue execution step 102.
Optionally, the second preset temperature can be set as 30 °, and the 3rd preset temperature can be setIt is 15 °.
Example, suppose that the first default duration is 30s, step 101 determines that whether air-conditioning is in lowTemperature refrigeration mode can be specially: determine whether outdoor environment temperature is less than 15 °, and outdoor dishWhether pipe temperature is less than 30 °, and lasting duration 30s; If outdoor environment temperature is less than 15 °,And outdoor coil pipe used temperature is less than 30 °, and lasting duration 30s, determine that air-conditioning is in low temperature systemCold pattern, continues execution step 102.
If step 102 determines that air-conditioning is in cryogenic refrigeration pattern, detect outdoor coil pipe used temperature to beNoly be greater than the first preset temperature and be less than the second preset temperature.
Wherein, the first preset temperature can be set as 25 °, like this, and according to institute in step 101The outdoor environment temperature of stating need be less than 15 °, is 25 °-30 ° by outdoor coil pipe used Temperature Setting, canTo ensure that outdoor coil pipe used temperature and outdoor environment temperature have the temperature difference of 10 ° at least, to guarantee air-conditioningSystem can be set up high-low pressure pressure reduction, ensures that cold-producing medium can proper flow.
Optionally, at definite air-conditioning, during in cryogenic refrigeration pattern, monitoring that can be real-time is outdoorWhether coil temperature is greater than the first preset temperature and is less than the second preset temperature, also can be periodicallyThe outdoor coil pipe used temperature of detection whether be greater than the first preset temperature and be less than the second preset temperature. ShowExample, can every 120 seconds (s) detect outdoor coil pipe used temperature whether be greater than the first preset temperature andBe less than the second preset temperature.
If whether outdoor coil pipe used temperature is greater than the first preset temperature and is less than the second preset temperature,Execution step 103; If outdoor coil pipe used temperature is less than the first preset temperature, perform step 104;If outdoor coil pipe used temperature is greater than the second preset temperature, perform step 105.
If the outdoor coil pipe used temperature of step 103 is greater than the first preset temperature and is less than the second default temperatureDegree, keeps current outdoor fan rotating speed.
Example, as step 101 and step 102 exemplified, if outdoor coil pipe used temperature is greater than25 ° and while being less than 30 °, keep current outdoor fan rotating speed.
If the outdoor coil pipe used temperature of step 104 is less than the first preset temperature, reduce current outdoor windFan rotating speed to the first rotating speed, the first rotating speed is more than or equal to the first preset rotation speed.
Wherein, the first preset rotation speed can be set as 150r/min (turning/per minute).
Example, as step 101 and step 102 exemplified, if outdoor coil pipe used temperature is less than25 °, reduce current outdoor fan rotating speed to the first rotating speed, the first rotating speed is less than current outdoorRotation speed of the fan, and be more than or equal to the first preset rotation speed.
Further, in the process declining at the first preset temperature for fear of outdoor coil pipe used temperatureTo the frequent adjustment of outdoor fan rotating speed, can prevent by the default transition temperature difference is set.
Concrete, after detecting that outdoor coil pipe used temperature is less than the first preset temperature, sensing chamberWhether outer coil temperature is less than the poor of the first preset temperature and the default transition temperature difference; So, step104 are specially: if outdoor coil pipe used temperature is less than the first preset temperature, and outdoor coil pipe used temperature is less thanWhen the difference of the first preset temperature and the default transition temperature difference, reduce current outdoor fan rotating speed to theOne rotating speed.
Example, suppose that the default transition temperature difference is 2 °, so, as shown in Figure 2, detectingWhen outdoor coil pipe used temperature is less than 25 °, detects outdoor coil pipe used temperature and whether be less than 23 ° (25 °-2 °); If outdoor coil pipe used temperature is less than 25 °, and outdoor coil pipe used temperature is while being less than 23 °,Reduce current outdoor fan rotating speed to the first rotating speed. Like this, can avoid outdoor dish being detectedWhen pipe temperature changes near 25 °, to the frequent adjustment of outdoor fan rotating speed.
If the outdoor coil pipe used temperature of step 105 is greater than the second preset temperature, improve current outdoor windFan rotating speed to the second rotating speed, the second rotating speed is less than or equal to the second preset rotation speed.
Wherein, the second preset rotation speed can be set as 500r/min.
Example as shown in step 101 and step 102, if when outdoor coil pipe used temperature is greater than 30 °,Improve current outdoor fan rotating speed to the second rotating speed, the second rotating speed is greater than current outdoor fan and turnsSpeed, and be less than or equal to the second preset rotation speed.
Further, in the process rising at the second preset temperature for fear of outdoor coil pipe used temperatureThe frequent fluctuation of outdoor fan rotating speed, can prevent by the default transition temperature difference is set.
Concrete, after detecting that outdoor coil pipe used temperature is greater than the second preset temperature, sensing chamberWhether outer coil temperature is greater than the second preset temperature and default transition temperature difference sum; So, step105 are specially: if detect, outdoor coil pipe used temperature is greater than the second preset temperature, and outdoor coil pipe used temperatureWhen degree is greater than the second preset temperature and default transition temperature difference sum, improves current outdoor fan and turnSpeed is to the first rotating speed.
Example, suppose that the default transition temperature difference is 2 °, so, as shown in Figure 3, detectingOutdoor coil pipe used temperature is greater than after 30 °, detects outdoor coil pipe used temperature and whether is greater than 32 ° (30 °+ 2 °); If outdoor coil pipe used temperature is greater than 30 °, and outdoor coil pipe used temperature is while being greater than 32 °,Improve current outdoor fan rotating speed to the second rotating speed. Like this, can avoid outdoor dish being detectedWhen pipe temperature changes near 30 °, to the frequent adjustment of outdoor fan rotating speed.
It should be noted that, as shown in Figures 2 and 3, can be by outdoor coil pipe used temperature be enteredRow relatively, determines that outdoor coil pipe used temperature is in ascendant trend or downward trend, is risingIn gesture, outdoor fan rotating speed can not reduce, and in downward trend, outdoor fan rotating speed can not improve,Like this, can make outdoor coil pipe used temperature stable in target zone rapidly, rotation speed of the fan can not produceRaw large fluctuation.
Example, as shown in Figure 3, in the time that outdoor coil pipe used temperature is elevated to 25 ° gradually, canAccording to identical step-length, outdoor fan rotating speed is adjusted to (as shown in solid line in Fig. 3), alsoCan adjust (as shown in chain-dotted line in Fig. 3) to outdoor fan rotating speed according to different step-lengths.For example: in the time that outdoor coil pipe used temperature is elevated to N ° (0 < N < 25) from 0 °, can be to outdoor windFan rotating speed is adjusted faster, in the time that outdoor coil pipe used temperature is elevated to 25 ° from N °, and canOutdoor fan rotating speed is carried out to slower adjustment. While reduction gradually for outdoor coil pipe used temperature, rightOutdoor fan rotating speed also can be adjusted according to identical or not identical step-length, no longer superfluous at thisState.
Further, in step 102, determine that air-conditioning is after cryogenic refrigeration pattern, the partyMethod also comprises: detect outdoor environment temperature and whether be greater than the 4th preset temperature, and continue second pre-If the time, or detect outdoor coil pipe used temperature and whether be greater than the 5th preset temperature, and continue secondDefault duration; If detect, outdoor environment temperature is greater than the 4th preset temperature, and continues second pre-If duration, or outdoor coil pipe used temperature is greater than the 5th preset temperature, and continue second default long,Exit cryogenic refrigeration pattern. Wherein, the 4th preset temperature is greater than the first preset temperature, and the 5thPreset temperature is greater than the second preset temperature.
Optionally, the 4th preset temperature can be set as 20 °, and the 5th preset temperature can be setIt is 38 °.
Example, suppose that the second default duration is 30s, so, at definite air-conditioning in low temperature systemAfter cold pattern, detect outdoor environment temperature and whether be greater than 20 °, and lasting duration 30s, orPerson detects outdoor coil pipe used temperature and whether is greater than 38 °, and lasting duration 30s; Outdoor when detectingEnvironment temperature is greater than 20 °, and lasting duration 30s, or detects that outdoor coil pipe used temperature is greater than38 ° time, and lasting duration 30s, cryogenic refrigeration pattern exited. Like this, can avoid air-conditioningIn the time that needs enter normal refrigeration and unapproachable situation.
