When the room temperature be greater than or equal to the indoor target temperature, and the indoor relative humidity be greater than the room
When interior target humidity, controls the air-conditioning and enter cool-down dehumidification mode；The cool-down dehumidification mode is mainly used for hot environment, and
And in the case that the indoor relative humidity is more than the indoor objects humidity, in this mode, the air-conditioning freezes, and
It dehumidifies.
When the room temperature be less than the indoor target temperature, and the indoor relative humidity be less than or equal to the room
When interior target humidity, controls the air-conditioning and enter heating moisturizing mode；The heating moisturizing mode is mainly used for low temperature environment, and
And the indoor relative humidity, in the indoor objects humidity situation below, in this mode, the airconditioning control electricity adds
Heat is heated, and is not dehumidified.
When the room temperature be less than the indoor target temperature, and the indoor relative humidity be greater than the indoor objects
When humidity, controls the air-conditioning and enter heating dehumidification mode；The heating dehumidification mode is mainly used for low temperature environment, and described
In the case that indoor relative humidity is more than the indoor objects humidity, in this mode, the airconditioning control electric heating system
Heat, and dehumidify.
The i.e. described step S200 specifically includes the following steps:
Step S210 compares the size of the room temperature and indoor target temperature, the indoor relative humidity and interior
The size of the size of target humidity and the inner coil pipe temperature and real-time dew-point temperature；
Step S220, when the room temperature is greater than or equal to the indoor target temperature, and the indoor relative humidity
When less than or equal to the indoor objects humidity, controls the air-conditioning and enter cooling moisture-retaining mode；
Step S230, when the room temperature is greater than or equal to the indoor target temperature, and the indoor relative humidity

When stating indoor objects humidity, controls the air-conditioning and enter heating dehumidification mode.
Size of the present embodiment by the comparison room temperature and the indoor target temperature, the indoor relative humidity
With the size of the indoor objects humidity and the size of the inner coil pipe temperature and the real-time dew-point temperature so that air-conditioning
It can select to enter different dehumidification modes, so that indoor environment is in constant temperature and perseverance according to indoor actual environment
The state of humidity.
Step S300 controls the running frequency and electric heating of compressor according to the dehumidification mode that the air-conditioning enters
State.
Specifically, in the present embodiment, when the air-conditioning enters cooling moisture-retaining mode, the air-conditioning can control the electricity
Heating is closed, and according to the size of the inner coil pipe temperature and the real-time dew-point temperature, controls the operation frequency of the compressor
Rate；For example, the air-conditioning can control the compressor in the case where the inner coil pipe temperature is greater than the real-time dew-point temperature
With the operation of the first predeterminated frequency；Since inner coil pipe temperature at this time is greater than real-time dew-point temperature, and therefore, the air-conditioning is only
It needs normally to be freezed, that is to say, that first predeterminated frequency may be configured as the compressor of air conditioner and normally freeze
Running frequency；And in the case where the inner coil pipe temperature is less than or equal to the real-time dew-point temperature, the air-conditioning can be controlled
The compressor is made to run with the second predeterminated frequency；Since inner coil pipe temperature at this time is less than real-time dew-point temperature, explanation
Air conditioner refrigerating temperature at this time is too low, and the running frequency of compressor is excessive, therefore, it is necessary to reduce the running frequency of compressor, with
Achieve the effect that constant temperature, that is to say, that settable second predeterminated frequency is less than first predeterminated frequency.
Specifically, in the present embodiment, when the air-conditioning enters cool-down dehumidification mode, the air-conditioning can control the electricity
Heating is closed, and according to the size of the inner coil pipe temperature and the real-time dew-point temperature, controls the operation frequency of the compressor
Rate；For example, the air-conditioning can control the compressor in the case where the inner coil pipe temperature is greater than the real-time dew-point temperature
With the operation of third predeterminated frequency, since inner coil pipe temperature at this time is greater than real-time dew-point temperature, illustrates that the interior of air-conditioning is changed
Hot device does not dehumidify, and needs to improve the working efficiency of compressor, thus achieve the effect that cooling and dehumidifying, it is therefore, settable described
Third predeterminated frequency is greater than first predeterminated frequency；And it is less than or equal to the real-time dew-point temperature in the inner coil pipe temperature
In the case where, the air-conditioning can control the compressor and be run with first predeterminated frequency；Due to inner coil pipe temperature at this time
It is less than real-time dew-point temperature, illustrates that the indoor heat exchanger of air-conditioning is dehumidifying, does not need the operation for improving compressor
Frequency, therefore it may only be necessary to keep normally freezing.
Specifically, in the present embodiment, it when the air-conditioning enters heating moisturizing mode, controls the electric heating and opens,
And close the compressor；It under this dehumidification mode, does not need to dehumidify, it is only necessary to be heated up, therefore, can be closed
Compressor, to reduce the energy consumption of air-conditioning；It is heated by opening the electric heating, so that indoor temperature is constant in some model
In enclosing.
Specifically, in the present embodiment, it when the air-conditioning enters heating dehumidification mode, controls the electric heating and opens,
And it controls indoor fan and is run with deep low gear；In this dehumidification mode, can also according to the inner coil pipe temperature and it is described in real time
The size of dew-point temperature controls the running frequency of the compressor；For example, being less than or equal to the reality in the inner coil pipe temperature
When dew-point temperature in the case where, the air-conditioning can control the compressor and be run with first predeterminated frequency；Due at this time
Inner coil pipe temperature is less than real-time dew-point temperature, illustrates that the indoor heat exchanger of air-conditioning is dehumidifying, and therefore, only needs
Keep the running frequency of compressor constant；And the case where the inner coil pipe temperature is greater than the real-time dew-point temperature
Under, illustrate that the indoor heat exchanger of air-conditioning does not dehumidify, need to improve the running frequency of compressor, therefore, the settable described 4th is pre-
If frequency is greater than first predeterminated frequency.
Specifically, for the control mode of different dehumidification modes are as follows:
1, when entering cooling moisture-retaining mode, control electric heating is closed；Later, pipe dish temperature T in comparingInner tubeWith real-time dew
Point temperature TDewSize；TInner tube≤TDew, control compressor reduction frequency (for example, reducing frequency 2Hz)；TInner tube> TDew, illustrate current
Indoor heat exchanger does not dehumidify, and control compressor keep frequency is constant.
2, when entering cool-down dehumidification mode, control electric heating is closed；Later, pipe dish temperature T in comparingInner tubeWith real-time dew
Point temperature TDewSize；TInner tube≤TDew, it is constant to control compressor keep frequency；TInner tube> TDew, illustrate that current indoor heat exchanger does not remove
Wet, control compressor increases frequency (for example, increasing frequency 2Hz).
