First embodiment
Referring to FIG. 2, Fig. 2 shows a kind of step processes of rotation speed of fan matching process provided in an embodiment of the present invention Figure.Above-mentioned rotation speed of fan matching process can be applied to air conditioner 1, as shown in Fig. 2, above-mentioned rotation speed of fan matching process can wrap Include following steps:
Step S101, the degree of supercooling for controlling the air conditioner 1 reach preset target degree of supercooling.
In embodiments of the present invention, when air conditioner 1 starts rotation speed of fan matching, control air conditioner 1 is run, and passes through tune The revolving speed of whole outer blower 4 makes the degree of supercooling of air conditioner 1 reach preassigned target degree of supercooling.By the degree of supercooling of air conditioner 1 The mode for being adjusted to preset target degree of supercooling can be:When the current degree of supercooling of air conditioner 1 is less than the preset target supercooling When spending, the revolving speed (for example, each 10min promotes 20r) of outer blower 4 is constantly promoted, until acquisition unit 5 detects air conditioner 1 Degree of supercooling reach the preset target degree of supercooling.When the current degree of supercooling of air conditioner 1 is greater than the preset target degree of supercooling, The revolving speed (for example, each 10min reduces 20r) for constantly lowering outer blower 4, until acquisition unit 5 detects the supercooling of air conditioner 1 Degree reaches the preset target degree of supercooling.
Step S102, record reach the air conditioner 1 corresponding first efficiency information when the target degree of supercooling.
In embodiments of the present invention, when detecting that 1 degree of supercooling of air conditioner reaches preset target degree of supercooling, air-conditioning is acquired The running state information of device 1, and corresponding first efficiency information is calculated accordingly.
Step S103 adjusts the target degree of supercooling.
In embodiments of the present invention, upper adjustment may include adjusting in entire embodiment at least twice.Step S103 with Instead of strict sequence, presence do not recycle between step S104.That is, every execution once carries out once target degree of supercooling Adjustment, process enters step S104, and after step S104 is finished, process can also turn again to step S103, directly To the condition for meeting termination circulation.It should be noted that the condition of above-mentioned termination circulation can be determination and efficiency inflection point occurs.It can Selection of land, when first time carrying out the adjustment of target degree of supercooling, by the sum of the preset target degree of supercooling and default degree, as the The primary target degree of supercooling adjusted, and process enters step S104 after target degree of supercooling has adjusted for the first time, to step Rapid S104 obtains corresponding second efficiency information after being performed, and two efficiency information can not determine whether efficiency inflection point, because This, process turns again in step S103, repeats the adjustment of target degree of supercooling.
Optionally, it is greater than when degree of supercooling is adjusted to the second efficiency information corresponding to target degree of supercooling adjusted for the first time The target degree of supercooling adjustment mode used when the first efficiency information for:
Target degree of supercooling is improved using default degree as increment on the basis of target degree of supercooling after the adjustment.And it is adjusting every time After process enter step S104, if still the not up to condition of loop termination, then flow after this time executes step S104 Journey turns again to step S103, to repeat after adjacent primary adjustment on the basis of corresponding target degree of supercooling, with preset degree Number is that increment improves the target degree of supercooling, using as this target degree of supercooling adjusted.It is, realizing with described default Degree is that increment gradually improves the target degree of supercooling.
Optionally, it is less than when degree of supercooling is adjusted to the second efficiency information corresponding to target degree of supercooling adjusted for the first time The target degree of supercooling adjustment mode used when the first efficiency information for:
The target degree of supercooling is reduced for decrement with the default degree on the basis of the preset target degree of supercooling. Process enters step S104 after each adjustment, if after this time execution step S104, the not up to item of loop termination Part, then process can turn again to step S103, and repeat after adjacent primary adjustment on the basis of corresponding target degree of supercooling with Default degree is that decrement reduces target degree of supercooling, using as this target degree of supercooling adjusted.It is, realizing with described pre- If degree is that decrement gradually reduces target degree of supercooling.
Step S104 controls the working condition of blower, and the degree of supercooling of the air conditioner 1 is adjusted to institute adjusted Target degree of supercooling is stated, is adjusted to the corresponding second efficiency letter of the target degree of supercooling adjusted to obtain the degree of supercooling every time Breath.
In embodiments of the present invention, after the target degree of supercooling adjustment every time, the working condition of blower is controlled, it will be described The degree of supercooling of air conditioner 1 is adjusted to the target degree of supercooling adjusted.And it is adjusted in degree of supercooling adjusted described After target degree of supercooling, the second current efficiency information of air conditioner 1 is obtained.
Optionally, if the target degree of supercooling that need to be adjusted to is target degree of supercooling adjusted for the first time, change described in The running speed of blower will be adjusted to the target degree of supercooling adjusted for the first time in the degree of supercooling of the air conditioner 1.For example, every The running speed of outer blower 4 is improved into 20r every 10min, until reaching target degree of supercooling adjusted for the first time.It is being subcooled After degree reaches the second efficiency information corresponding when target degree of supercooling adjusted for the first time, process can come back to step S103 In, so as to be adjusted again to target degree of supercooling.
After second of target degree of supercooling adjusts, and meets degree of supercooling and be adjusted to target degree of supercooling institute adjusted for the first time When the corresponding second efficiency information is greater than the first efficiency information, the running speed for changing blower is repeated, by the air-conditioning The target degree of supercooling after readjusting is adjusted in the degree of supercooling of device 1, to obtain corresponding second efficiency again Information.And according to the second efficiency information obtained again, whether the circulation between judgment step S103 and step S104 may be used To terminate, specifically, can by judge the second efficiency information that this is obtained whether be less than it is adjacent it is last adjust after it is corresponding The second efficiency information.If it is less, terminating circulation, process enters step S105;If it is not, then process continues Step S103 is returned to, repeats to adjust target degree of supercooling.
After second of target degree of supercooling adjusts, and degree of supercooling is adjusted to corresponding to target degree of supercooling adjusted for the first time The second efficiency information be less than the first efficiency information when, change the running speed of the blower, to lower State the degree of supercooling of air conditioner 1.Specifically, the revolving speed 20r that outer blower 4 is lowered every 10min, until by the air conditioner 1 Degree of supercooling be reduced to the difference between the preset target degree of supercooling and the default degree, lower the supercooling to obtain The second efficiency information after degree.If lowering the second efficiency information after the degree of supercooling to believe less than first efficiency Breath then stops adjusting the target degree of supercooling, i.e. circulation between termination step S103 and step S104, and process enters step S105.If lowering the second efficiency information after degree of supercooling is greater than the first efficiency information, process returns to step S103, Target degree of supercooling is readjusted, and after the adjustment, process returns to step S104, and the operation that repetition changes the blower turns The degree of supercooling of the air conditioner 1 is adjusted downward to the target degree of supercooling after readjusting, to obtain air conditioner 1 again by speed Second efficiency information, further according to obtaining corresponding second efficiency information, following between judgment step S103 and step S104 again Whether ring can terminate.Specifically, can be by judging whether the second efficiency information that this is obtained is less than adjacent last tune The corresponding second efficiency information, determines whether efficiency inflection point occur after section.If it is less, there is efficiency inflection point in determination, Circulation is terminated, process enters step S105;If it is not, then still cannot determine whether that efficiency inflection point process occur continues back To step S103, repeat to adjust target degree of supercooling.It is, until the second efficiency information reacquired is less than adjacent The corresponding second efficiency information after last time is adjusted.
Step S105 determines efficiency inflection point according to the first efficiency information and multiple second efficiency information.
It in embodiments of the present invention, can also be by this space-time in each acquisition and while record the efficiency information of air conditioner 1 Adjust the rotation speed of fan and degree of supercooling record of device 1.So that each efficiency information can correspond to a rotation speed of fan and degree of supercooling.From Maximum energy valid value is determined in first efficiency information and multiple second efficiency information, is turned using the maximum energy valid value as the efficiency Point.As an implementation, according to the corresponding relationship between efficiency information and degree of supercooling, along the direction that degree of supercooling is gradually incremented by First efficiency information and multiple second efficiency information are arranged, the first efficiency information and multiple second energy after obtaining arrangement The peak value in information is imitated, using the peak value as efficiency inflection point.
Step S106, corresponding rotation speed of fan is as matching rotation speed of fan when air conditioner 1 is in efficiency inflection point.
In embodiments of the present invention, the running speed of corresponding outer blower 4 is as most when air conditioner 1 being in efficiency inflection point Good matching rotation speed of fan, the matching rotation speed of fan can take into account the efficiency and degree of supercooling of air conditioner 1.
The rotation speed of fan matching process provided through this embodiment can make each air conditioner 1 that can be most suitable for The rotation speed of fan of itself.While so that each air conditioner 1 is reached optimal degree of supercooling, efficiency can be taken into account, improves making for user With experience.
