Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
With the development of science and technology and the improvement of living standard of people, the function of the IFD (electrostatic precipitator air purification technology) has become an important reference when selecting fresh air equipment such as an air conditioner.
When being equipped with the new trend equipment operation of IFD function, if the IFD function is opened, the granule in the IFD filter core adsorbed air, the time length of central processing unit MCU (micro Controller Unit) record is the operating time length of filter core. When the new trend equipment operation, and the IFD function was closed, the granule in the air naturally fell into the IFD filter core, and the time length of MCU record was for the time length of stewing of filter core this moment.
The result of use of IFD function in the aspect of dust removal purification is good, but as shown in FIG. 1, along with the increase of equipment duration of use, accumulational particulate matter increases on the IFD filter core, and the windage increase of air conditioner return air inlet, intake reduce to fan rotational speed descends in leading to, is less than initial rotational speed, and then the air output of equipment reduces gradually, causes the comfortable nature of user to experience the variation, leads to the user to complain even.
The utility model provides a control method of air output, be used for new trend equipment to control new trend equipment air output invariable, control new trend equipment promptly and not take place the air output to reduce because of long time using, ensure that the air output of new trend equipment all satisfies the initial parameter of leaving the factory at any time, guarantee user's comfortable nature experience.
Because new trend equipment is after operation a period, because of the attached particulate matter causes the windage increase on the IFD filter core to fan rotational speed descends in leading to, makes the air output of new trend equipment reduce, consequently, if will guarantee user's travelling comfort and experience, need ensure that the air output of new trend equipment is invariable, guarantee promptly that new trend equipment can not reduce the air output along with the increase of length of operation.
This is disclosed along with the increase of the length of operation of new trend equipment, suitably compensates to the rotational speed of internal fan to under the power effect of fan including, can overcome the windage on the IFD filter core and keep the air output invariable. That is to say, under the condition of not changing the IFD filter core, in order to continuously overcome the windage that adnexed particulate matter caused on the IFD filter core (this windage is a change value in operation), through according to certain mode along with the increase of the length of time of operation and adjust interior fan rotational speed for the operating rotational speed of interior fan is greater than initial rotational speed, in order to guarantee that the air output of new trend equipment is unanimous with initial air output.
For example, the theoretical operating speed of the internal fan of a certain fresh air device at a strong wind gear is 1500r/min, and after a certain period of operation, for example 3000 hours, the particulate matter attached to the IFD filter element causes a certain wind resistance, and the actual operating speed of the internal fan is reduced to 1400 r/min. At this time, if the air output of the fresh air device is to be kept as the theoretical value, the operation speed of the inner fan needs to be increased, so that the operation speed is greater than the theoretical operation speed.
It should be noted that in the present disclosure, the wind shield value is taken as a description of the wind speed in the operation of the fresh air device.

and S400, determining the running windshield value of the fresh air equipment at a preset gear according to the adjustment coefficient, the actual windshield value and the target windshield value.
According to the control method for the air output, the adjustment coefficient is determined through the historical use time of the filter element in the operation process of the fresh air equipment, the actual windshield value and the target windshield value corresponding to the preset gear of the fresh air equipment are combined, the operation windshield value of the fresh air equipment at the preset gear is determined, the fresh air equipment can be guaranteed to continuously and stably operate at the target windshield value at the preset gear, the closed-loop adjustment of the air output is achieved, and the comfortable experience of a user is guaranteed.
In step S100, the historical service time T of the filter element of the fresh air equipment is obtainedHistory of。
In the present disclosure, the filter cartridge has a historical use duration THistory ofNamely the historical use duration of the fresh air equipment. Take the new trend equipment that possesses the IFD function as an example, the history duration of use of filter core includes the equipment duration of use under the IFD function open mode and the equipment duration of use under the IFD function unopened condition.

The adjustment coefficient K is along with the historical use duration T of the fresh air equipmentHistory ofI.e. the adjustment coefficient is a variable rather than a fixed value as the fresh air device runs. In some embodiments, the adjustment factorK, and according to the historical usage time T in step S100History ofThe acquisition frequencies are consistent.
The rotating speed of the fresh air equipment is adjusted according to the adjusting coefficient K, and the air output of the fresh air equipment can be regulated and controlled. For example, the adjusting coefficient K may be a rotation speed adjusting coefficient of an inner fan of the fresh air device, and the operation rotation speed of the inner fan is adjusted according to the adjusting coefficient K, so that the air output of the fresh air device in the operation process is constant or changes according to a predetermined rule.
In step S300, an actual windshield value R corresponding to the preset gear of the fresh air device is obtainedPractice ofAnd a target windshield value RTarget. Wherein the preset gear is matched with the preset air output. That is to say, the actual windshield value R under the preset gear corresponding to the preset air output to be reached by the operation of the fresh air equipment is obtainedPractice ofAnd a target windshield value RTarget。
Wherein the actual windshield value RPractice ofFor the duration T of the historical use of the new trend equipmentHistory ofThen, before correcting or adjusting the rotating speed of the inner fan, the actually achievable windshield value is obtained; target windshield value RTargetTo achieve the theoretical wind shield value corresponding to the preset wind output. For example, the theoretical rotation speed (factory initial rotation speed) of a certain fresh air device at the middle gear is 1200r/min, namely the target windshield value of the middle gear; in operation THistory ofThe actual operating speed in the mid-range after 2000 hours is 1050r/min, which is the actual windshield value.
In step S400, an operating damper value of the fresh air device at a preset gear is determined according to the adjustment coefficient, the actual damper value, and the target damper value.
According to the current historical use time length T determined in the step S200History ofAdjustment coefficient K, actual windshield value R corresponding to the preset gear obtained in step S300Practice ofAnd a target windshield value RTargetDetermining the running windshield value R of the preset gear under the historical use timeOperation ofSo that the fresh air equipment is in the preset gear and the running windshield value ROperation ofCan stably output presets during operationAir output, the realization air output is invariable, promotes user experience.

For example, with a rest period of time TStanding stillTo the operation duration TOperation ofMultiplying by a first preset coefficient; or with a running time period TOperation ofFor the standard, the standing time length TStanding stillMultiplied by a second preset coefficient.
The first preset coefficient and the second preset coefficient can be obtained by testing the fresh air equipment for a certain time under the conditions that the IFD function is started and not started, and specific numerical values are not limited in the disclosure.
In some embodiments, the historical usage duration THistory ofTime duration TOperation of+ standing time period TStanding stillX the first coefficient η.
Wherein the first coefficient eta is the standing time length TStanding stillTime duration to operation TOperation ofThe efficiency of conversion, that is, the fresh air equipment of same performance and parameter, in same air circumstance, when starting same predetermined gear operation and being the same, does not start the absorbent air of filter core of IFD functionThe ratio of the amount of particulate matter in the air that is adsorbed by the filter element that initiates the IFD function. That is, if it is considered that the adsorption efficiency of the IFD filter element with respect to particulate matter is 1 when the IFD function is activated, the adsorption efficiency of the IFD filter element with respect to particulate matter is η when the IFD function is not activated.
