Data just accumulate once, the data for reading counter can obtain first number.
Step S60 determines first object duration according to first number and the preset duration；
The product of first number and preset duration is first object duration.
When it is described power on operation duration more than or equal to first object duration when, return execute it is described according to the entrance temperature
Degree and the outlet temperature, the step of judging whether the revolving speed for needing to reduce outdoor fan；
And/or
After the step of control indoor fan reduces current rotating speed, further includes:
Step S70 obtains second number of the current fall-back of the indoor fan；
After air conditioner powers on or after receiving initialization directive, by zeros data in the corresponding counter of indoor fan,
When the revolving speed for determining to be not necessarily to reduce outdoor fan according to above-mentioned steps S10 to step S40, and delivery temperature is more than or equal to default
When temperature threshold, the data in the corresponding counter of indoor fan are just accumulated once, and the data for reading counter can obtain
Two numbers.
Step S80 determines the second target duration according to second number and the preset duration；
The product of second number and preset duration is as the second target duration.
When it is described power on operation duration more than or equal to the second target duration when, return to that execute the judgement exhaust warm
The step of whether degree is greater than or equal to preset temperature threshold.
The efficiency situation of air conditioner is persistently monitored by the above-mentioned means, can realize, and outdoor fan is adaptively adjusted
Revolving speed.The revolving speed of outdoor fan can also be gradually reduced, or in excessive discharge temperature, when energy efficiency of air conditioner is bad to room
The revolving speed of inner blower gradually reduces, to obtain more accurate tachometer value, realizes and protects while improving air-conditioning efficiency and reliability
Demonstrate,proving air-conditioning has exchange capability of heat as big as possible.
In addition, can also determine indoor fan regulation coefficient according to first number, outdoor fan tune is determined according to second number
