Step S803, compares air-out set temperature T and indoor leaving air temp t, in the time of t<T, and execution step S804, in the time of t=T, execution step S806, in the time of t>T, execution step S807.
Step S804, whether the current running frequency f that detects compressor is lower than the default regulating frequency higher limit F1 of compressor, if, while being f<F1, improve compressor operating frequency f, preset after duration d minute through the 5th, return to step S803, until the current running frequency f of compressor equals the default regulating frequency higher limit F1 of compressor, when f=F1, execution step S805.
Step S805, reduces indoor fan rotating speed s, after default duration d minute, returns to step S803 through the 5th.
Step S806, is failure to actuate, and after default duration c minute, returns to step S803 through the 4th.
If indoor actual leaving air temp t equals air-out set temperature T, represent that current indoor actual leaving air temp meets user's demand, therefore control device does not perform an action, and then returns to step S803, proceeds comparison.
Step S807, whether the current running frequency f that detects compressor is higher than the default regulating frequency lower limit F2 of compressor, if, while being f>F2, reduce compressor operating frequency f, preset after duration d minute through the 5th, return to step S803, equal the default regulating frequency lower limit F2 of compressor to the current running frequency f of compressor, when f=F2, execution step S808.
Step S808, improves indoor fan rotating speed s, then, through the 5th default duration d minute, returns to step S803.
In one embodiment of the invention, the span of second default duration a minute is 0.5-10, and the second default duration can be half a minute to 10 minute.The 3rd span of presetting duration b minute is 0.5-10, and the 3rd default duration can be half a minute to 10 minute.The 4th span of presetting duration c minute is 0.5-10, and the 4th default duration can be half a minute to 10 minute.The 5th span of presetting duration d minute is 0.5-10, and the 5th default duration can be half a minute to 10 minute.
