The distance answered is defined as the distance of outdoor unit and fixed obstacle；Second judgment sub-unit 224 judges that currently condensing saturation degree is
No condensation saturation degree when being more than normal mounting space；When currently condensation saturation degree is more than default condensation saturation degree, on the one hand
It further determined that air conditioner is arranged on small space, on the other hand tentatively judge whether current air conditioner fan-out capability is less than institute
Need ability, then, searching unit 226 according to the air conditioner and the distance of fixed obstacle that prestore, the corresponding relation of output parameter,
Outdoor unit output parameter corresponding with the distance of fixed obstacle is searched, the 3rd judgment sub-unit 228 judges current output parameter
Whether it is less than default output parameter, if whether current output parameter is less than default output parameter, illustrates that now air conditioner is because of installation
Narrow space result in fan-out capability deficiency, then determines current condensation saturation degree and current output parameter meets default bar
Part, control unit 24 control air conditioner to carry out output operation according to required ability output parameter, reduced outside air conditioner chamber again
