When user triggers humidification function by remote control or humidifying air conditioner control panel, humidifying air conditioner it is automatically controlled Box will detect humidification instruction.Now, it will determine that and humidify humidification type corresponding to instruction, the humidification type may include normal add Wet, powerful humidification etc..It is of course also possible to by increasing by a humidification decision circuitry in electric-controlled box 50, by obtaining Interior Space The current humidity of gas, and by current humidity compared with target humidity, to determine whether to start humidification function.To carry out Humidification, then produce humidification instruction.Detecting module 110 is when detecting humidification instruction, it is determined that humidification type corresponding to humidification instruction.
Humidifying mode control module 120 is specifically used for:
When identified humidification type is normally humidifies, the air conditioner is controlled to be maintained at current operational mode.Example Such as, if current operating modes of air conditioner is refrigeration mode, keep the operational mode of current air conditioner constant, while start and add Wet function, that is, start water pump 51.
When identified humidification type is powerful humidification, the air conditioner is controlled to switch to system by current operational mode Heat pattern.For example, when if current operating modes of air conditioner is refrigeration mode, control air conditioner switches to heating by refrigeration mode Pattern, to lift the temperature on indoor heat exchanger surface.Start humidification function simultaneously, that is, start water pump 51, water pump 51 is by water from water Extracted in case to heat exchanger, and its bottom is flow to by heat exchanger at the top of heat exchanger.The temperature on indoor heat exchanger surface Rise, the evaporation of the water on indoor heat exchanger surface will be accelerated, so as to improve the humidity of the air by indoor heat exchanger surface, entered And improve the humidity of room air.Due under powerful humidifying mode, to control air conditioner to switch to heating mode, if air conditioner is cut Alternatively preceding pattern is just heating mode, then need not switch over.If the pattern before air conditioner switching is refrigeration mode, and When now switching to heating mode for a long time, the comfort level of user will be influenceed, therefore heating mode is being switched to by refrigeration mode Afterwards a period of time, heating mode is switched back into refrigeration mode.Or after heating mode is switched to by refrigeration mode, will be real-time Indoor humidity is detected, if indoor humidity reaches desired value, switches back into refrigeration mode.
When identified humidification type is automatic humidification, current humidity and environment temperature are detected, and judge current humidity Whether reach humidification entry condition with environment temperature, if reaching normally humidification entry condition, control air conditioner starts normal add It is wet;If reaching powerful humidified condition, control air conditioner starts powerful humidification.If not up to humidification entry condition, does not start Humidification.The normal humidified condition can be set according to specific circumstances with powerful humidified condition.By taking powerful humidified condition as an example:When Preceding humidity value is less than target humidity value, and the difference of the target humidity value and the current humidity value is more than preset humidity threshold Value, indoor temperature are less than preset temperature threshold value.Such as:Current humidity value is less than target humidity value and differed greatly with target humidity value In 20%RH, environment temperature is less than 20 DEG C, can automatically turn on powerful humidification function.
It is understood that in order to save humidification power consumption, after humidifying mode is started, indoor humidity will be detected in real time, If indoor humidity reaches target humidity, stop humidification.Or air conditioner is when receiving the humidification halt instruction that user sends, Stop humidification.If the switching of operational mode, the operational mode before switching back into are carried out under humidifying mode.
When starting humidifying mode, water pump control modules 130 control the water pump in water tank 50 to open, so that water tank 50 In water humidifying air conditioner is entered by pipeline, and by the top downstream of the heat exchanger 20 in humidifying air conditioner and under to heat exchanger 20 bottom, then it is pooled in the drip tray 60 of the bottom of heat exchanger 20, finally flows back into water tank 50 again.
