It will be appreciated to those of skill in the art that in the inventive solutions, the interior of air conditioner of the invention
Machine includes with the first heat exchange branch of parallel relationship setting and the second heat exchange branch, and the first heat exchange branch road is provided with first
Heat exchanger and the first expansion valve, the second heat exchange branch road are provided with the second heat exchanger and the second expansion valve, the dehumidifying control
Method processed includes: to obtain the dew-point temperature of room air；Obtain the saturation evaporating temperature of the indoor unit；According to the Interior Space
The saturation evaporating temperature of the dew-point temperature of gas and the indoor unit is selectively adjusted first expansion valve and/or described
The aperture of second expansion valve.The present invention passes through the dew-point temperature of the room air and the saturation evaporating temperature of the indoor unit
To judge that the vapor in air is liquefied by latent heat form for the ratio of water, to judge the dehumidifying effect energy of the air conditioner
The no dehumidification for meeting user, then the dehumidifying effect further according to the air conditioner is selectively adjusted first expansion valve
And/or the aperture of second expansion valve so that the dehumidifying effect of the air conditioner can always with the dehumidification phase of user
Matching, and then while effect on moisture extraction is effectively ensured, additionally it is possible to the heat exchange amount and air output of the air conditioner is effectively ensured, with
Just the heat exchange range that the air conditioner is effectively ensured is unaffected.
Further, in a preferred embodiment of the invention, if the dew-point temperature of the room air and the interior
The difference of the saturation evaporating temperature of machine is less than first preset temperature, then the controller judges the dehumidifying energy of the air conditioner
Power is insufficient for dehumidification, and in this case, the controller makes the aperture regulation zero of first expansion valve and makes
Second expansion valve maintains current aperture.It is understood that in the case where closing first expansion valve, described first
There is no heat transferring mediums to pass through in heat exchanger, and the evaporating pressure and evaporating temperature of the indoor unit can all drastically reduce, so that institute
The difference for stating the dew-point temperature of room air and the saturation evaporating temperature of the indoor unit is quickly increased, so that described
The dehumidifying effect of air conditioner obtains fast lifting, to enable the air conditioner to meet the dehumidification of user as early as possible.
Further, in a preferred embodiment of the invention, the feelings for being zero in the aperture regulation of first expansion valve
Under condition, the controller can also after a preset time lapses, according to the dew-point temperature of the room air and the interior
The saturation evaporating temperature of machine is selectively adjusted the aperture of second expansion valve.First expansion valve aperture
In the case where being adjusted to zero, the controller be can continue to through the dew-point temperature of the room air and the indoor unit
Saturation evaporating temperature liquefies to judge that the vapor in air passes through latent heat form for the ratio of water, to judge the air conditioner
Dehumidifying effect can meet the dehumidification of user, then further according to the dehumidifying effect of the air conditioner selectively to described
The aperture of second expansion valve is adjusted, so that the dehumidifying effect of the air conditioner can be bonded user demand always.
Further, in a preferred embodiment of the invention, the feelings for being zero in the aperture regulation of first expansion valve
Under condition, after preset time, if the difference of the dew-point temperature of the room air and the saturation evaporating temperature of the indoor unit
Value is less than second preset temperature, then the controller judges that the dehumidifying effect of the air conditioner is still unable to satisfy user and needs
It asks, therefore, the aperture that the controller controls second expansion valve reduces, to make the saturation of the indoor unit evaporate temperature
Degree can further decrease, so that the dehumidifying effect of the air conditioner is further increased, so that the dehumidifying of the air conditioner
Ability can meet user demand as early as possible.
Further, in a preferred embodiment of the invention, the feelings for being zero in the aperture regulation of first expansion valve
Under condition, after preset time, if the difference of the dew-point temperature of the room air and the saturation evaporating temperature of the indoor unit
Value is equal to second preset temperature, then the controller judges that the dehumidifying effect of the air conditioner has been sufficient for user's
Dehumidification, in this case, the controller are not adjusted the aperture of second expansion valve, to be effectively ensured
The dehumidifying effect for stating air conditioner can satisfy user demand.
Further, in a preferred embodiment of the invention, the feelings for being zero in the aperture regulation of first expansion valve
Under condition, after preset time, if the difference of the dew-point temperature of the room air and the saturation evaporating temperature of the indoor unit
Value is greater than second preset temperature, then the controller judges that the dehumidifying effect of the air conditioner at this time has exceeded user and needed
It asks, in this case, the controller increases the aperture of second expansion valve, so that the dehumidifying effect of the air conditioner pastes
The dehumidification at family is shared, and then on the basis of guaranteeing that user's dehumidification is satisfied, additionally it is possible to institute be effectively ensured
State the exchange capability of heat of air conditioner.
Further, in a preferred embodiment of the invention, if the dew-point temperature of the room air and the interior
The difference of the saturation evaporating temperature of machine is equal to first preset temperature, then the controller judges the dehumidifying energy of the air conditioner
Power has been able to the dehumidification for meeting user, and in this case, the controller is not to first expansion valve and described
The aperture of two expansion valves is adjusted, to can satisfy the basis of user demand in the dehumidifying effect of the guarantee air conditioner
On, additionally it is possible to the exchange capability of heat of the air conditioner is effectively ensured.
Further, in a preferred embodiment of the invention, if the dew-point temperature of the room air and the interior
The difference of the saturation evaporating temperature of machine is greater than first preset temperature, then the controller judges the dehumidifying energy of the air conditioner
