Step S30, is more than or equal to the first default indoor environment relative humidity at indoor environment relative humidity φWhen φ 1, and in the difference of described indoor environment relative humidity φ and the first default indoor environment relative humidity φ 1When increase, improve frequency of air condition compressor, indoor motor rotating speed and electronic expansion valve opening.
Step S40, is more than or equal to the first default indoor environment at described indoor environment relative humidity φ relativeWhen humidity φ 1, and at described indoor environment relative humidity φ and the first default indoor environment relative humidity φ 1Difference while reducing, reduce frequency of air condition compressor, indoor motor rotating speed and electronic expansion valve opening.
In the time that indoor environment relative humidity φ is more than or equal to the first default indoor environment relative humidity φ 1, sentenceWhether the difference of disconnected described indoor environment relative humidity φ and the first default indoor environment relative humidity φ 1 increasesIncrease in the difference of described indoor environment relative humidity φ and the first default indoor environment relative humidity φ 1 greatly,Time, improve frequency of air condition compressor, indoor motor rotating speed and electronic expansion valve opening. Described air conditioner compressedThe raising ratio of unit frequency, indoor motor rotating speed and electronic expansion valve opening is corresponding with described difference,When described difference is larger, the amplitude of raising is larger; In difference more hour, the amplitude of raising is less. InstituteWhen stating indoor environment relative humidity φ and being more than or equal to the first default indoor environment relative humidity φ 1, and in instituteWhen the difference of stating indoor environment relative humidity φ and the first default indoor environment relative humidity φ 1 reduces, reduceFrequency of air condition compressor, indoor motor rotating speed and electronic expansion valve opening. And when difference is larger, reductionAmplitude is larger; In difference more hour, the amplitude of reduction is less.
The present embodiment is by air conditioner dehumidification process, by indoor environment relative humidity φ and the first default chamberInterior envionmental humidity φ 1 compares, and is more than or equal to first default indoor at indoor environment relative humidity φAfter envionmental humidity φ 1, whether change to control the dehumidification process of air-conditioning according to difference. Effectively avoid orderFront convertible frequency air-conditioner is also simply according to indoor environment temperature control sky for the control law of dehumidifying operationAdjust dehumidifying operation, make the accuracy of Dehumidification controlling poor, reduced the problem of comfort of air conditioner. Provide oneKind of Dehumidification controlling mode, control the dehumidification process of air-conditioning in conjunction with many kinds of parameters, improved Dehumidification controllingAccuracy and comfort of air conditioner.
With reference to figure 2, the described indoor environment relative humidity of described comparison φ is relative wet with the first default indoor environmentAfter the step of degree φ 1, also comprise:

Step S60, in the time that indoor environment relative humidity φ is greater than the second default indoor environment relative humidity φ 2,Enter dehumidification mode.
In the present embodiment, relative wet with the first default indoor environment at comparison indoor environment relative humidity φAfter degree φ 1, obtaining judged result, is that indoor environment relative humidity φ is less than the first default chamber in judged resultWhen interior envionmental humidity φ 1, judge that indoor environment relative humidity φ is less than the first default indoor environment relativeWhether the state of humidity φ 1 remains unchanged, at described indoor environment relative humidity φ and the first default indoor ringThe difference of border relative humidity φ 1 continues to increase or described indoor environment relative humidity φ and the first default indoor ringThe difference of border relative humidity φ 1 remain unchanged Preset Time (according to air conditioner dehumidification performance and user's request setting,For example, be 1 minute or 2 minutes etc.) after, dehumidification mode exited. Exiting dehumidifying according to aforesaid wayFor example, after pattern, in real time or detect a period of time (, 30s or 1 minute etc.) and obtain current indoor environmentRelative humidity φ, when indoor environment relative humidity φ is greater than the second default indoor environment relative humidity φ 2, entersEnter dehumidification mode, the described second default indoor environment relative humidity according to indoor environment demand, weather and/orHeat pump performance arranges, the wherein said second default indoor environment relative humidity φ 2 > the described first default indoor ringBorder relative humidity φ 1. Relatively wet by be less than the first default indoor environment at indoor environment relative humidity φDegree is when φ 1, and while maintaining Preset Time, exits dehumidification mode; Be greater than at indoor environment relative humidity φWhen two default indoor environment relative humidity φ 2, enter dehumidification mode. More complicated and dehumidifying is accurately providedMode controlling mode, and then improve the degree of accuracy that dehumidification mode moves, improve the comfort level of air conditioner dehumidification.
With reference to figure 3, described in enter the step of dehumidification mode after, also comprise:
Step S70, be less than the first preset temperature t1, and indoor environment is relatively wet at indoor environment temperature T1When degree φ is less than the 3rd default indoor environment relative humidity φ 3, automatically exit dehumidification mode;
Step S80, is more than or equal to preset temperature threshold value t1 at indoor environment temperature T1, or indoor environmentWhen relative humidity φ is more than or equal to the 3rd default indoor environment relative humidity φ 3, carry out in the manner described aboveThe step of air conditioner dehumidification.
Entering after dehumidification mode according to the process of step S60, obtain current indoor environment temperature T1 withAnd indoor environment relative humidity φ, indoor environment temperature T1 and the first preset temperature t1 are compared, and by chamberInterior envionmental humidity φ and the 3rd default indoor environment relative humidity φ 3 compare; Or first by indoor environment temperatureDegree T1 and the first preset temperature t1 compare, then by indoor environment relative humidity φ and the 3rd default indoor ringBorder relative humidity φ 3 compares; Or first that indoor environment relative humidity φ is relative wet with the 3rd default indoor environmentDegree φ 3 compares, then indoor environment temperature T1 and the first preset temperature t1 are compared. The described first default temperatureDegree t1 is according to user's request, weather condition and/or heat pump performance setting, for example, is 26 degree or 27 degreeDeng, the described the 3rd default indoor environment relative humidity φ 3 is according to weather condition, user type and/or air-conditioningCan arrange, for example, be 40% or 50% etc. Be less than the first preset temperature t1 at indoor environment temperature T1,And when indoor environment relative humidity φ is less than the 3rd default indoor environment relative humidity φ 3, automatically exit dehumidifyingPattern. , pleasant in the situation that, exit dehumidification mode in indoor environment; In indoor environment temperatureDegree T1 is more than or equal to preset temperature threshold value t1, or indoor environment relative humidity φ is more than or equal to the 3rd pre-If when indoor environment relative humidity φ 3, carry out the process of air conditioner dehumidification according to the mode in above-described embodiment.The present embodiment is by constantly detecting current indoor environment temperature T1 and indoor environment relative humidity φ, rootDifference according to indoor environment temperature T1 and indoor environment relative humidity φ and preset value is automatically opened or closesClose dehumidification mode, make the control of dehumidification mode more accurate, improve environmental amenity degree in air conditioning chamber.
With reference to figure 4, described method also comprises:
