Capacity be capacity that capacity that capacity corresponding to 18, No. 3 indoor units is 28, No. 4 indoor units is 71, No. 5 indoor units be 56,
The capacity of No. 6 indoor units is that the capacity that the capacity of 36, No. 7 indoor units is 18, No. 8 indoor units is 18.Wherein, 2,4,5,6,7,8
Number indoor unit is first kind indoor unit (abbreviation DH)；1, No. 3 indoor units are the second class indoor unit (referred to as heating).In addition, first
The operating status of class indoor unit is divided into first state (i.e. A condition) and the second state (i.e. B state), now according to predetermined condition：
First kind indoor unit one is divided into 5 groups, respectively：(2)、(4)、(5)、(6、7)、(8).Give tacit consent to No. 2 interiors
The operating status of the indoor unit that machine operates to A condition as first group, 4,5,6,7, No. 8 indoor units is B state, when No. 2 interiors
Machine is switched to No. 4 indoor units and operates to A condition, the operating status of 2,5,6,7, No. 8 indoor units after 0min runs to 10min
For B state, after No. 4 indoor units run 20min from 10min, it is switched to No. 5 indoor units and operates to A condition, 2,4,6,7, No. 8
The operating status of indoor unit is B state, after No. 5 indoor units run 30min from 20min, is switched to 6, No. 7 indoor units and operates to
The operating status of A condition, 2,4,5, No. 8 indoor units is B state, after 6, No. 7 indoor units run 40min from 30min, is switched to
No. 8 indoor units operate to A condition, and the operating status of 2,4,5,6, No. 7 indoor units is B state.In this way, dehumidifying in need room
Between complete the dehumidifying of a predetermined period, second or more of dehumidifying can be carried out as needed.When indoor unit runs shape
When state changes, such as：2,4,5,6, No. 7 indoor units are switched to first kind indoor unit；1,3, No. 8 indoor units are switched to second
Class indoor unit.It is possible to 2,4,5,6, No. 7 indoor units are grouped again according to predetermined condition, and according to above-mentioned steps
Restart the operating status of control first kind indoor unit.
In the above-mentioned methods, indoor unit is divided into first kind indoor unit and the second class indoor unit, wherein first kind indoor unit
For dehumidifying, the second class is used for indoor machine in heating.The capacity of first kind indoor unit and the second class indoor unit is obtained respectively.By first
Class indoor unit is grouped, and the sum of capacity of every group of first kind indoor unit is respectively less than the sum of the capacity of the second class indoor unit.So
After control every group of first kind indoor unit and run predetermined period of time according to first state, remaining group runs according to the second state.Its
In, first state includes：The unlatching of the first electric expansion valve is controlled, First Heat Exchanger carries out cool-down dehumidification；It is swollen to control the second electronics
Swollen valve is closed, and the second heat exchanger does not work；Second state includes：Control the closing of the first electric expansion valve, First Heat Exchanger not work
Make；The unlatching of the second electric expansion valve is controlled, the second heat exchanger is carried out to prevent the resident control of refrigerant.In this way, when air conditioner is by one
Platform outdoor unit and more indoor units at when, if part indoor unit is in heating operation state, other part indoor unit is in
Between the operating status, such as storing of dehumidifying, toilet, the ground such as kitchen are when needing individually dehumidifying, can solve due to heating operation shape
The indoor unit of state and the indoor unit capacity of dehumidifying operating status mismatch, and lead to the problem that wet-out property is inadequate, to ensure to remove
Wet effect improves the Experience Degree of user.
