Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below with reference to drawings and Examples, the present invention is described in further detail.
Referring to Fig. 1, this figure show the flow chart of first embodiment of air-conditioner condensation prevention control method of the present invention.
As it is shown in figure 1, the process that this embodiment realizes the anti-condensation control of air-conditioner is as follows:
Step 101: air-conditioner runs refrigeration mode or dehumidification mode.
General, when air-conditioner runs refrigeration mode or dehumidification mode, it is only possible to produce condensation.Therefore, first precondition entering anti-condensation control is that air-conditioner runs refrigeration mode or dehumidification mode.And, the operational mode of air-conditioner is by controller of air conditioner control, therefore, it is very easy to get the present mode of operation of air-conditioner.
Step 102: when air-conditioner runs refrigeration mode or dehumidification mode, detect the rotating speed of indoor machine fan in real time.
Indoor machine fan rotating speed is set by air-conditioner control panel or remote controller by user, and the controller of air-conditioner runs according to setting speed according to user's setup control indoor machine fan.Thus, air-conditioner controller can be easy to know the current rotating speed of indoor machine fan.
Step 103: judge that whether the rotating speed of the indoor machine fan that step 102 detects is less than setting speed.If so, step 104 is performed；Otherwise, perform step 102, continue the rotating speed of indoor machine fan is detected.
In view of air-conditioner be usually the rotating speed of indoor machine fan low to certain value time be only possible to produce condensation, thus pre-set a setting speed, when only the current rotating speed of indoor machine fan is less than this setting speed, just can enter into anti-condensation control.Such as, air-conditioner includes high, medium and low wind speed, and the tachometer value arranging the indoor machine fan corresponding to middle wind speed or low wind speed is setting speed.If the rotating speed of current indoor machine fan is not less than setting speed, condensation will not be produced, do not determine whether and perform anti-condensation process.Only when the rotating speed of current indoor machine fan is less than setting speed, just determine whether, to decide whether to perform anti-condensation process.
Step 104: if the rotating speed of current indoor machine fan is less than setting speed, timing is started less than the moment of setting speed first from rotating speed, judge that whether indoor machine fan sets the time with the rotating speed continuous working period less than setting speed more than one, and this setting time sets time labelling with first.This first setting time can be pre-stored in the memorizer of air-conditioner before air-conditioner dispatches from the factory, and this first setting time is corresponding with a household air-conditioner parameter preset value.If the continuous working period, more than the first setting time, performs step 105；Otherwise, continue timing, until the continuous working period is more than the first setting time.
Step 105: if indoor machine fan is to set the time less than the rotating speed continuous working period of setting speed more than first, owing to indoor set air circulation is few, air outlet of indoor set temperature is low, if indoor air humidity is big, the most as easy as rolling off a log condensation that can produce, therefore, enters anti-condensation control process.
Step 106: enter anti-condensation control process, controls indoor machine fan and runs the first rotating speed, controls outdoor machine fan and runs the 3rd rotating speed.Wherein, the first rotating speed is more than setting speed, and the 3rd rotating speed is more than the running speed of off-premises station before the anti-condensation control process of entrance.
And, the first rotating speed and the 3rd rotating speed are not changeless values, and the first rotating speed preferably enters the anti-condensation rotating speed controlling Cheng Qian to indoor machine fan and is directly proportional, and the 3rd rotating speed preferably enters the anti-condensation rotating speed controlling Cheng Qian to outdoor machine fan and is directly proportional.
After entering anti-condensation control process, control indoor machine fan and run with the first rotating speed higher than setting speed, increase indoor set air circulation, increase the exchange capability of heat with vaporizer, it is possible to increase the air themperature after heat exchange, reduce the possibility that condensation produces.Being additionally, since indoor machine fan rotating speed to raise, air current flow speed is accelerated, even if produce less condensation, it is also possible to the air-flow fast along with flowing velocity and take out of in air, it is to avoid stop at and air outlet, wind guide component internal at indoor set and produce condensation.While controlling the increase of indoor set rotation speed of the fan, control off-premises station rotation speed of the fan also to raise, increase off-premises station exchange capability of heat, and then improve the refrigeration of vaporizer, raise for offsetting the air outlet temperature caused because indoor machine fan rotating speed improves, reach the stable of air outlet temperature or small change, it is to avoid air outlet variations in temperature is excessive and affects the refrigeration comfortableness of user.
And, in this embodiment, by indoor machine fan using rotating speed continuous service certain time of the first setting speed as the precondition entering anti-condensation control, it is possible in time, efficiently perform anti-condensation control.
Refer to Fig. 2, the figure shows the flow chart of second embodiment of air-conditioner condensation prevention control method of the present invention.
As in figure 2 it is shown, the process that this embodiment realizes the anti-condensation control of air-conditioner is as follows:
Step 201: meet anti-condensation control condition, enters anti-condensation control.
Anti-condensation control condition may refer to Fig. 1 embodiment step 101 to the condition described by step 104, namely, air-conditioner runs refrigeration mode or dehumidification mode, indoor machine fan was more than for the first setting time with the rotating speed continuous working period less than setting speed, then judge to meet anti-condensation control condition, enter anti-condensation control.
Step 202: enter anti-condensation control process, controls indoor machine fan and runs the first rotating speed, controls outdoor machine fan and runs the 3rd rotating speed.Wherein, the first rotating speed is more than setting speed, and the 3rd rotating speed is more than the running speed of off-premises station before the anti-condensation control process of entrance.
The principle of this step and effect refer to the description of Fig. 1 embodiment.
Step 203: judge whether the operation time entering anti-condensation control process reaches to set the anti-condensation operation time.If so, perform step 207, exit anti-condensation control；If it is not, perform step 204.
This embodiment pre-sets the setting anti-condensation operation time, and the operation time of anti-condensation control process reaches this setting anti-condensation operation time exit criteria as anti-condensation control process.
Step 204: if the operation time of anti-condensation control process the most not up to set the anti-condensation operation time, continue executing with anti-condensation control, during indoor machine fan and outdoor machine fan are controlled by step 202, then detect indoor set coil temperature and indoor environment temperature.Wherein, indoor set coil temperature can be detected by the temperature sensor being arranged on evaporator coil, and indoor environment temperature can detect with the temperature sensor being disposed in the interior machine air inlet.
Step 205: judge whether the coil temperature that step 204 detects no more than sets the temperature difference less than setting coil temperature and the indoor environment temperature difference.If so, step 206 is performed；Otherwise, go to step 202 and continue executing with step 202 anti-condensation control backward and judgement.
Setting coil temperature is a preset setting value, can be relevant to the household air-conditioner parameter temperature value the most stored when dispatching from the factory of indoor set.The indoor environment temperature difference refers to real time environment temperature indoor during the anti-condensation control that step 204 is detected and the difference entered between the indoor environment temperature before anti-condensation control process, after this difference is used for characterizing anti-condensation control and the temperature rise of indoor environment temperature before anti-condensation control.
Step 206: if the coil temperature of step 205 determination step 204 detection no more than sets the temperature difference less than setting coil temperature and the indoor environment temperature difference, show that now coil temperature is relatively low, as easy as rolling off a log generation condensation, and indoor environment temperature change is little, thus, for preventing the generation of condensation further, then control indoor machine fan and run the second rotating speed.Wherein, the second rotating speed is more than the first rotating speed in step 202.Namely, in the case of the temperature rise of generation condensation relatively low at coil temperature, as easy as rolling off a log and indoor environment temperature is little, improve indoor machine fan rotating speed further, prevent condensation from producing, and the change of indoor environment temperature is still within the scope of air-conditioner user institute is receptible, does not results in being decreased obviously of comfortableness.Then, go to step 203, continue executing with follow-up judgement, it is achieved the persistence of anti-condensation control process.
In this embodiment, first rotating speed, the second rotating speed and the 3rd rotating speed are not changeless value, first rotating speed and the second rotating speed preferably enter the anti-condensation rotating speed controlling Cheng Qian to indoor machine fan and are directly proportional, and the 3rd rotating speed preferably enters the anti-condensation rotating speed controlling Cheng Qian to outdoor machine fan and is directly proportional.
Step 207: if step 203 judges that the operation time of anti-condensation control process reaches to set the anti-condensation operation time, then exit anti-condensation control.
Step 208: when exiting anti-condensation control, the rotating speed of the rotating speed and outdoor machine fan that control indoor machine fan recovers respectively to entering the anti-condensation corresponding rotating speed controlling Cheng Qian, to realize air-conditioner according to the operation of user's setup parameter.
Additionally, when exiting anti-condensation control, the aperture controlling electric expansion valve reduces, to prevent from causing the deterioration of condensation after indoor machine fan rotating speed reduces suddenly.
Step 209: electric expansion valve runs with the aperture after reducing.
Step 210: judge whether the time that electric expansion valve runs institute's continuous service with the aperture after reducing reached for the second setting time.If so, step 211 is performed；If it is not, go to step 209, electric expansion valve still runs with the aperture after reducing.This second setting time is also the time value pre-set according to household air-conditioner parameter.
Step 211: if step 210 judges whether the time that electric expansion valve runs institute's continuous service with the aperture after reducing reached for the second setting time, the aperture controlling electric expansion valve recovers the aperture before extremely reducing, thus, control air-conditioner properly functioning.
Exit anti-condensation control process and electric expansion valve aperture recover to reduce before aperture and properly functioning after, can circulate execution meet anti-condensation condition and enter anti-condensation control and meet exit criteria and exit the process of anti-condensation control.
