S209, air-conditioning system carry out low temperature dehumidification, that is, reduce the running frequency of compressor, and the operation for reducing indoor fan turns
Speed, and reduce the aperture of throttle such as electric expansion valve, so as to reduce cold medium flux.Wherein, indoor environment temperature compared with
When low, the running frequency of compressor is reduced, indoor environment temperature rises, and indoor environment relative humidity reduces；Reduce interior simultaneously
The running speed of blower fan, reduce the aperture of electric expansion valve, indoor heat exchanger Guan Wen is less than dew-point temperature, reach the mesh of dehumidifying
, operation power consumption is not only reduced, while also meet the requirement of comfortableness.And carry out low temperature dehumidification operation in air-conditioning system
After 30min, step S204 is again returned to, continues to judge indoor environment relative humidity D1.
S210, air-conditioning system carry out conventional dehumidifying, i.e., do not reduce the running frequency of compressor, reduce the operation of indoor fan
Rotating speed and the aperture for reducing electric expansion valve, reduce refrigerant flow direction, indoor heat exchanger Guan Wen is less than dew-point temperature, reach dehumidifying
Purpose, and cause fluctuations in indoor temperature it is small.After air-conditioning system carries out low temperature dehumidification operation 30min, step is again returned to
S204, continue to judge indoor environment relative humidity D1.
Therefore, in the present embodiment, by by the refrigerating operaton program of air-conditioning system and humid control program effectively coupling
It is combined, realizes indoor temperature and humidity coordinated signals, not only ensures the stability of air-conditioning system refrigerating operaton, also reduce
The fluctuation of indoor temperature and humidity, substantially increase the comfortableness of user.
According to another embodiment of the invention, when the operational mode of air-conditioning system is heating mode and indoor environment temperature
During more than three preset temperatures, the operational mode and indoor environment temperature that judge air-conditioning system meet preparatory condition.
Also, in step s 103, air-conditioning system is controlled according to indoor environment temperature and indoor environment relative humidity
System specifically includes：When indoor environment relative humidity is more than three preset values, control the air-conditioning system continue heating operation with
Carry out heating dehumidifying；When indoor environment relative humidity is more than or equal to the 4th preset value and is less than or equal to the 3rd preset value
When, control the air-conditioning system to keep the heating mode operation.
Further, in step s 103, according to indoor environment temperature and indoor environment relative humidity to the air-conditioning system
System is controlled, in addition to：When indoor environment relative humidity is less than four preset value, indoor environment temperature is determined whether
Whether degree is more than the 4th preset temperature, wherein, the 4th preset temperature is more than the 3rd preset temperature；If indoor environment
Temperature is more than the 4th preset temperature, then reduces the running frequency of compressor in the air-conditioning system, and reduces design temperature,
So that the air-conditioning system carries out decreasing temperature and increasing humidity；If indoor environment temperature is less than or equal to the 4th preset temperature, control
Humidification device in the air-conditioning system is made to be operated.
Specifically, as shown in figure 4, the control method of above-mentioned air-conditioning system comprises the following steps：
S401, judge the present mode of operation of air-conditioning system.

S403, judges whether indoor environment temperature T1 is more than such as 15 DEG C of the 3rd preset temperature.If it is, perform step
S404；If it is not, then return to step S402.Say, when air-conditioning system is run with heating mode, and indoor environment temperature is less than
Or during equal to three preset temperatures, heat process priority.
That is, when air-conditioning system is run with heating mode, indoor environment temperature is detected by indoor temperature transmitter
T1 changes are spent, as 15 DEG C of T1 ＞, initially enter the detection of indoor environment relative humidity；And during T1≤15 DEG C, air-conditioning system continues
Heating operation.
S404, indoor environment relative humidity D1 is detected by humidity sensor, and indoor environment relative humidity D1 is carried out
Judge.Wherein, if indoor environment relative humidity more than the 3rd preset value is D1 ＞ 60%RH, step S405 is performed；If
Indoor environment relative humidity is more than or equal to the 4th preset value and is 40%RH≤D1≤60% less than or equal to the 3rd preset value
RH, then perform step S406；If indoor environment relative humidity is D1 ＜ 40%RH less than the 4th preset value, step is performed
S407。
S405, judging that current indoor humidity is high, control air-conditioning system continues heating operation, and heating dehumidifying is carried out to interior,
Step S404 is then back to, continues to judge indoor environment relative humidity D1.
That is, heating dehumidifying is the air-conditioning system heating operation in the case of low temperature and high relative humidity, indoor temperature is gradual
Height, indoor environment relative humidity gradually reduce, wherein, the relation of temperature and relative humidity is as shown in Figure 5.
S406, it is determined as that current indoor humidity is suitable, humid control part is failure to actuate, and air-conditioning system keeps heating mode fortune
OK, step S404 is then back to, continues to judge indoor environment relative humidity D1.
S407, it is determined as that current indoor humidity is low, humidification action is performed, into step S408.
S408, judges whether indoor environment temperature T1 is more than such as 22 DEG C of the 4th preset temperature.If indoor environment temperature
22 DEG C of T1 ＞, then perform step S409；If 15 DEG C of ＜ T1≤22 DEG C, step S410 is performed.
S409, air-conditioning system carry out decreasing temperature and increasing humidity, that is, reduce the running frequency of compressor, and reducing design temperature will for example set
Constant temperature degree is adjusted to 22 DEG C.Wherein, decreasing temperature and increasing humidity refers to, when indoor environment temperature is more than four preset temperatures, changes air-conditioning system
Design temperature when system is run with heating mode, the design temperature after change is less than current indoor temperature, by reducing compressor
Running frequency cause indoor temperature to reach the design temperature after change, also, indoor environment temperature reduces, and indoor environment is relative
Humidity raises.And after air-conditioning system carries out decreasing temperature and increasing humidity operation 20min, step S404 is again returned to, is continued to indoor environment
Relative humidity D1 is judged.
S410, air-conditioning system carry out conventional humidification, that is, control humidification device to start to act, be then back to step S404, after
It is continuous that indoor environment relative humidity D1 is judged.
Therefore, in the present embodiment, by by the heating operation program of air-conditioning system and humid control program effectively coupling
It is combined, realizes indoor temperature and humidity coordinated signals, while air-conditioning system heating capacity is ensured, has also reached humidity
The purpose of control, ensure the comfortableness of indoor environment, while also ensure the stability of air-conditioning system heating operation, reduce Indoor Temperature
