When multi-line system present mode of operation is heating mode, multi-line system can recall outdoor from memory space
Relation table between the operation wind file of the operation wind file and the second outdoor fan of environment temperature and the first outdoor fan, and will be above-mentioned
Outdoor environment temperature and the relation table carry out retrieval and match to obtain the operation wind file of the first outdoor fan and second Room exogenous wind
The operation wind file of machine.
S104, controls the first outdoor fan and the second outdoor fan is worked with the operation wind file obtained.
S3, if meeting first between the middle portion temperature of the first outdoor heat exchanger and the middle portion temperature of the second outdoor heat exchanger
Preset relation then carries out upshift control to the operation wind file of the first outdoor fan.Wherein, the first preset relation can be according to practical feelings
Condition is demarcated.
In one embodiment of the invention, when the middle portion temperature and second outdoor heat exchanger to the first outdoor heat exchanger
When relationship between middle portion temperature is judged, the middle portion temperature and second outdoor heat exchanger of the first outdoor heat exchanger are also obtained
The mean temperature of middle portion temperature, wherein when the temperature difference between the middle portion temperature and mean temperature of the first outdoor heat exchanger be greater than etc.
When fiducial temperature, judge to meet between the middle portion temperature of the first outdoor heat exchanger and the middle portion temperature of the second outdoor heat exchanger
One preset relation.Wherein, fiducial temperature can be demarcated according to the actual situation.
For example, when the middle portion temperature of the first outdoor heat exchanger and the temperature difference of above-mentioned mean temperature are more than or equal to fiducial temperature
When, it can control the operation wind file of the first outdoor fan to rise one grade, to guarantee the heat exchange efficiency of the first outdoor heat exchanger.
S4, if meeting second between the middle portion temperature of the first outdoor heat exchanger and the middle portion temperature of the second outdoor heat exchanger
