Fig. 1 is a kind of flow signal carrying out anti-condensation method using automatically cleaning shown according to an exemplary embodiment Figure.As shown in Figure 1, this method includes：

Step S101：It obtains indoor humidity and judges whether to need to carry out anti-condensation operation.

Step S102：If necessary to carry out anti-condensation operation, then controls air-conditioning and carry out automatically cleaning operation to prevent condensation.

In the present embodiment, within air-conditioning systems be directed to whether execute it is anti-condensation operation be preset with Rule of judgment, in difference In air-conditioning system, which can be the same or different.In some optional embodiments, in same air-conditioning system, In the air-conditioning different operating stage, the Rule of judgment is unique, in some optional embodiments, in same air-conditioning system, in air-conditioning The different operating stage, for whether executing anti-condensation operation setting and have different Rule of judgment.

In the present embodiment, there are many modes for obtaining indoor humidity, optionally, is passed by the humidity that air-conditioning system carries Sensor measures, or obtains the indoor humidity detected by other equipment by networking mode, or passes through other data It calculates and obtains indoor temperature.

In the present embodiment, by the indoor humidity of acquisition and the preset Rule of judgment of air-conditioning system determine the need for into The anti-condensation operation of row.

In some optional embodiments, if the Rule of judgment for needing to carry out anti-condensation operation is that indoor humidity RH is more than and sets Determine threshold value RHt.

When the indoor temperature of acquisition meets condition, i.e., indoor humidity is larger, there is the risk for generating condensation, it is thus determined that It needs to carry out anti-condensation operation.Wherein, the value range of the given threshold RHt is between 60%~90%.Optionally, described Given threshold RHt is 60%, 65%, 70%, 75%, 80%, 85% or 90%.The value size and air-conditioning of the given threshold Setting target temperature it is related, the value of the more low then described given threshold of the setting target temperature is smaller, such as：When the mesh When marking 20 DEG C of set temperature, given threshold RHt is 65%, and when 27 DEG C of the target set temperature, given threshold RHt is 80%.When setting target temperature is relatively low, leaving air temp is relatively low, therefore under the conditions of same humidity, and setting target temperature is relatively low When be more also easy to produce condensation, need to carry out anti-condensation operation in advance, then set that target temperature is lower, the value of the given threshold is got over It is small.

In some optional embodiments, if the Rule of judgment for needing to carry out anti-condensation operation is that indoor humidity RH continues greatly Reach setting duration in the time of given threshold RHt.

At this point, when the indoor temperature of acquisition meets condition, i.e., indoor humidity is larger in the poor time, and there are generation condensations Risk, it is thus determined that needing to carry out anti-condensation operation.Wherein, the value size and setting target temperature size phase of duration are set It closes, when mono- timings of the indoor humidity RH, setting target temperature is lower, and leaving air temp is lower, is also easy to produce condensation, it is therefore desirable to carry It is preceding to carry out anti-condensation operation, then it is smaller to set duration value.

In a step 102, when judging result is to need to carry out anti-condensation operation, control air-conditioning carry out automatically cleaning operation to prevent Hydrogenesis in air is frosted or ice sheet by solidifying white stage of automatically cleaning pattern, and is attached to heat exchanger by only condensation Outer surface reduces the humidity of room air, avoids generating condensation, the frost for being condensed heat exchanger outer surface by the defrost stage Melting layer Cheng Shui, water are collected to drip tray discharge, avoid dropping onto generation security risk on other air-conditioning components and reduce empty Adjust the component service life.It realizes anti-condensation by automatically cleaning operation while realizing automatically cleaning to air-conditioning.

Fig. 2 is a kind of flow signal carrying out anti-condensation method using automatically cleaning shown according to an exemplary embodiment Figure.As shown in Fig. 2, this method includes：

Step S201：It obtains indoor humidity and temperature information and judges whether to need to carry out according to the first preset condition anti-condensation Dew operation.

Step S202：If necessary to carry out anti-condensation operation, then controls air-conditioning and carry out automatically cleaning operation to prevent condensation.

In the present embodiment, it is different from previous embodiment, in step s 201, the indoor humidity that air-conditioning system passes through acquisition It determines the need for carrying out anti-condensation operation with temperature information and the preset Rule of judgment of air-conditioning system.

During controlling air-conditioning, common temperature parameter includes：Indoor temperature, outdoor temperature, indoor coil Temperature, outdoor coil temperature, indoor unit intake air temperature, air outlet of indoor set temperature, compressor air suction mouth temperature and compressor Exhaust port temperatures etc..

In different embodiments, air-conditioning system can pass through the specific data of above-mentioned one or more temperature parameters of acquisition And comprehensive indoor humidity judges whether to need to carry out anti-condensation operation.

In the present embodiment, there are many modes for obtaining temperature data, optionally, is passed by the temperature that air-conditioning system carries Sensor measures, or obtains the temperature data detected by other equipment by networking mode, or passes through other data It calculates and obtains a certain temperature data.

In the present embodiment, comprehensive many kinds of parameters judges whether to need to carry out anti-condensation operation, takes into account the anti-condensation of air-conditioning Other operating conditions except dew operation so that control process is more accurate, and the operating status of air-conditioning more meets the demand of user, keeps away It is big to have exempted from temperature fluctuation in the process of running, discomfort is brought to human body.

In some optional embodiments, in step S201, temperature information includes indoor environment temperature；The first default item Part includes：If indoor humidity is more than the temperature difference t1 of given threshold RHt and indoor environment temperature Troom and target temperature Tset Less than or equal to the first setting temperature difference, then need to carry out anti-condensation operation.

When meeting the first preset condition, when indoor humidity is larger, it is also easy to produce condensation, so anti-condensation phase should be carried out Operation is closed, meanwhile, the temperature difference t1 of indoor environment temperature Troom and target temperature Tset is less than or equal to the first setting temperature difference, Indoor temperature substantially meets user demand, at this time it is contemplated that preferentially carrying out anti-condensation relevant operation, executes step S202 controls Air-conditioning processed carries out automatically cleaning operation to prevent condensation.

In some optional embodiments, in step S201, temperature information includes indoor coil pipe；The first default item Part includes：If indoor humidity is more than given threshold RHt and the temperature difference t2 of indoor coil pipe Tcoi1 and dew-point temperature T1 is small In or equal to the second setting temperature difference, then need to carry out anti-condensation operation.

When meeting first preset condition, when indoor humidity is larger, be also easy to produce condensation, indoor coil pipe Tcoi1 with The temperature difference t2 of dew-point temperature T1 be less than or equal to second setting the temperature difference, coil temperature be less than dew-point temperature, and coil temperature and Difference between dew-point temperature is larger, condensation speed, should quickly carry out anti-condensation, execution step S202 control air-conditioning progress Automatically cleaning is operated to prevent condensation.

In step S202, control air-conditioning carries out automatically cleaning operation to prevent condensation, passes through the solidifying white rank of automatically cleaning pattern Section frosts the hydrogenesis in air or ice sheet, and is attached to the outer surface of heat exchanger, reduces the humidity of room air, avoids Generate condensation, the frost melting layer Cheng Shui for heat exchanger outer surface being condensed by the defrost stage, water is collected to drip tray discharge, It avoids dropping onto and generates security risk on other air-conditioning components and reduce the air-conditioning component service life.It is real by automatically cleaning operation Show anti-condensation while having realized automatically cleaning to air-conditioning.

In the aforementioned embodiment, dew-point temperature is less than by automatically cleaning scheme control indoor heat exchanger surface temperature, makes sky Large quantity of moisture condensation in gas forms frost or ice sheet in heat exchanger surface, melts frost or ice sheet by solidifying white process, is realizing Air-conditioning is self-cleaning while obtaining anti-condensation effect, but automatically cleaning pattern may cause leaving air temp rapid drawdown, gives user Discomfort is brought, therefore, in some embodiments, is carried out before the step in executing above-described embodiment shallower anti-condensation Relevant operation carries out anti-condensation operation when cannot achieve the anti-condensation automatically cleaning pattern that is then turned in the short time.

In some optional embodiments, as shown in figure 3, carrying out anti-condensation method using automatically cleaning and including：

Step S301：It obtains indoor humidity and judges whether to need to carry out anti-condensation operation, if it is desired, then carry out anti-condensation Dew operation.

Due to when outlet frame mouth temperature is relatively low indoor humidity it is larger in the case of than indoor humidity it is smaller in the case of more Condensation easily occurs, therefore when executing anti-condensation operation, using indoor humidity as whether opening the basis for estimation of anti-condensation operation. May be implemented to execute anti-condensation operation as early as possible using indoor humidity as basis for estimation, avoid the occurrence of humidity it is excessive it is anti-condensation not in time The phenomenon that.

It should be understood that when needing to carry out anti-condensation operation, then anti-condensation operation is carried out, is not needing anti-condensation operation When, then maintain current working status constant.
