Embodiments in accordance with the present invention, there is provided a kind of state of air-conditioning determines method, the method for the present invention as shown in Figure 1 An embodiment schematic flow sheet.The state of the air-conditioning determines that method can include：
At step S110, current operating parameter of the outdoor fan of the air-conditioning under current state is obtained.Wherein, institute Current state is stated, can be included：The first operation shape when the outdoor heat exchanger of debugging mode, the air-conditioning during installation is unplugged At least one of second running status when state and the non-frosting of the outdoor heat exchanger.
For example：Monitoring to DC fan motor parameter outside air conditioner chamber.
For example：Realize the monitoring of fan of outdoor unit of air conditioner parameter.
For example：The monitoring of fan of outdoor unit of air conditioner (i.e. DC fan motor of outdoor unit of air conditioner) parameter.
Thus, by the acquisition of the current operating parameter to air-conditioning under various current states during debugging, operation etc., Can be to provide to the determination of the current state of air-conditioning and subsequent treatment precisely and reliable foundation, property easy to use is good.
In an optional example, the operational factor can include：At least one of voltage, electric current, power consumption.
For example：Fan electromotor working voltage that can be by more than replaces with running current.
For example：Fan electromotor working voltage that can be by more than replaces with operation power consumption.

In an optional example, the outdoor fan for obtaining the air-conditioning in step s 110 is current under current state One process of operational factor, can include：When the current state can include the debugging mode, obtain in the tune The current operating parameter of the outdoor fan recorded by control chip under examination state.
For example：Example shown in Figure 10, installation personnel are manipulated by plate, make control chip record ring now The working voltage B (commissioning test voltage B when debugging) of the outdoor fan at border temperature and supply voltage.
Thus, the current operating parameter under debugging mode, acquisition modes letter are obtained by way of being recorded by control chip Just, the data reliability of acquisition is high.
In an optional example, can obtain current in the method for the present invention with reference to shown in Fig. 2 under the first running status The schematic flow sheet of one embodiment of operational factor, further illustrates and obtains the outdoor fan of the air-conditioning in step s 110 and exist Another process of current operating parameter under current state.
Step S210, when the current state can include first running status, determines the outdoor heat exchanger Whether block.
It is alternatively possible to combine in the method for the present invention shown in Fig. 5 whether determine outdoor heat exchanger under the first running status The schematic flow sheet of one embodiment of blocking, determines the tool whether outdoor heat exchanger blocks in further illustrating step S210 Body process.
Step S510, obtains the current outdoor environment temperature of the outdoor fan local environment detected by environment temperature-sensitive bag Degree, and obtain the current running voltage of the outdoor fan.
Step S520, according to the current outdoor environment temperature and the current running voltage, determines the outdoor heat exchange Whether device blocks.
For example：First is pre-conditioned, can include：May insure correctly to record each of current fan electromotor working voltage X The condition of kind and restriction, for example：Current operation is not at making frozen condition of outdoor heat exchanger blocking etc..Alternatively, this One is pre-conditioned, can be realized by combining the means such as detection environment temperature-sensitive bag, operation low pressure.
Thus, determine whether outdoor heat exchanger blocks by way of to outdoor environment temperature and working voltage detection, really Determine mode easy, determine that result accuracy is good.
Step S220, when the outdoor heat exchanger is unplugged, obtains by the air-conditioning of control chip record described The current operating parameter under first running status.
For example：Example shown in Figure 11, after installation, when meeting first and being pre-conditioned, control chip record The normal operating voltage X of current fan electromotor.
Thus, obtain current under the first running status of control chip record by determination outdoor heat exchanger when unplugged Operational factor, the promptness and accuracy for obtaining data are preferable.
In an optional example, can obtain current in the method for the present invention with reference to shown in Fig. 3 under the second running status The schematic flow sheet of one embodiment of operational factor, further illustrates and obtains the outdoor fan of the air-conditioning in step s 110 and exist Another process of current operating parameter under current state.
Step S310, when the current state can include second running status, when the air-conditioning once defrosts In the first preset duration afterwards, the outdoor heat exchanger whether frosting is determined.
It is alternatively possible to combine in the method for the present invention shown in Fig. 6 whether determine outdoor heat exchanger under the second running status The schematic flow sheet of one embodiment of frosting, determines the outdoor heat exchanger whether tool of frosting in further illustrating step S310 Body process.
Step S610, after the defrosting of the outdoor heat exchanger terminates, obtains the room detected by environment temperature-sensitive bag The current outdoor environment temperature of outer blower fan local environment, and obtain the current running voltage of the outdoor fan.
Step S620, according to the current environmental temperature and/or the current running voltage, it is determined that the institute after defrosting terminates State outdoor heat exchanger whether again frosting.
For example：Second is pre-conditioned, can include：May insure that outdoor heat converter will not cause windage to increase because of frosting Plus, i.e., correctly record various conditions and the restriction of current fan operation voltage U.Alternatively, second is pre-conditioned, can be by removing Frost terminates rear timing, and combining environmental temperature is realized with the means such as low pressure detection are run.
Thus, whether the outdoor heat exchanger after defrosting is determined by way of detecting to environment temperature and working voltage Frosting again, accuracy are good, and reliability is high.
Step S320, when the non-frosting of the outdoor heat exchanger, obtains by the outdoor fan of control chip record Current first operational factor.
Example shown in Figure 12, after installation, when meeting second and being pre-conditioned, control chip record fan electricity First working voltage U of machine.
Step S330, in the second preset duration after current first operational factor is obtained, obtains by control core Current second operational factor of the outdoor fan of piece record.
For example：Afterwards at interval of L minutes, the second working voltage V of current blower fan is recorded.
Thus, the current operation ginseng under the second running status is obtained during frosting non-by determination outdoor heat exchanger after the frost is removed Number, obtains the opportunity of data precisely, and the data reliability of acquisition is high.
At step S120, under the current state, determine whether the current operating parameter reaches default operation ginseng Number.
Thus, by determining whether the current operating parameter under current state reaches the default operation ginseng under current state Number, it may be determined that ruuning situation of the air-conditioning under current state, ease-to-operate are good, the reliability that state determines are high.
In an optional example, can debugging mode and the first running status in the method for the present invention with reference to shown in Fig. 4 The lower schematic flow sheet for determining whether current operating parameter meets an embodiment of default operational factor, further illustrates step Determine in S120 whether the current operating parameter reaches a process of default operational factor.

Step S420, under the current state, according to the current operating condition and the preset operating conditions, to institute State current operating parameter to be modified, to obtain the amendment operational factor under the current state.
For example：To correct to working voltage B with supply voltage during debugging by environment temperature during debugging, obtain current Magnitude of voltage α (i.e. debugging amendment voltage α) under rated supply voltage.
For example：Under first running status, power supply electricity during environment temperature and normal operation when normally running can be passed through Pressure is corrected to normal operating voltage X, obtains the magnitude of voltage β under current nominal supply voltage.
Step S430, determines whether the amendment operational factor is default more than described with the difference of the default operational factor Operational factor.
For example：When judging to install, whether ventilation situation meets set-mounted requirement, improves reliability when installing.
For example：There is the not smooth situation of ventilation in realization in judging whether to have running, there is provided accident analysis number after sale According to.
For example：Under debugging mode, can pass through to correct the difference of voltage α and A, (debug with default installation decision content Z Decision content Z) contrast, determine whether to meet installation requirement.
For example：Under first running status, by the difference of voltage β and X, with default operation decision content Y contrasts, worked as Front state is not smooth with the presence or absence of ventilation.
Thus, after by being modified to the current operating parameter under debugging mode, the first running status, by amendment operation Parameter is compared with decision content with the difference of default operational factor, with current under determining debugging mode, the first running status Whether operational factor meets default operational factor, and reliability is high, and accuracy is good.
In an optional example, in step S120, determine whether the current operating parameter reaches default operational factor Another process, can include：When the current state can include second running status, first operation is determined Whether parameter is more than the default operational factor with the difference of second operational factor.
For example：Judgement for defrosting condition provides foundation.
For example：The decision condition of defrosting is provided.
For example：By the second working voltage V and the difference of the first working voltage U, contrast with default defrosting decision content P, Whether the outdoor heat exchanger frost layer for obtaining current state reaches defrosting condition.
Thus, by the difference of two current operating parameters under the second running status is compared with decision content, with Determine whether current operating parameter reaches default operational factor i.e. defrosting condition under the second running status, and operating reliability is high, and When property is good.
