30%~40%, the revolving speed of the second breeze fan 130 can be the 90%~100% of rated speed, with shorten outdoor air into
Enter indoor flow path, the air quantity of the outdoor air being inhaled into made maximumlly simultaneously, to avoid 140 frosting of indoor heat exchanger,
And guarantee the air quantity of the cold air blown out by the first air outlet 112, the temperature difference of indoor environment is reduced in the vertical direction.Such as the
The revolving speed of one breeze fan 120 can be the 40% of rated speed, and the revolving speed of the second breeze fan 130 can be rated speed
90%；The revolving speed of first breeze fan 120 can be the 33% of rated speed, and the revolving speed of the second breeze fan 130 can be specified turn
The 100% of speed；The revolving speed of first breeze fan 120 can be the 30% of rated speed, and the revolving speed of the second breeze fan 130 can be volume
Determine 95% of revolving speed etc..
In the case where the air humidity of outdoor environment is less than default humidity threshold, when indoor heat exchanger 140 is in heating
When state and outdoor environment temperature are more than or equal to indoor environment temperature, the revolving speed of the first breeze fan 120 can be rated speed
20%~30%, the revolving speed of the second breeze fan 130 can be the 90%~100% of rated speed, with shorten outdoor air into
Enter indoor flow path, the air quantity of the outdoor air being inhaled into is made maximumlly simultaneously, to go out more cold airs through second
Air port 113 is blown out, and the characteristics of floating using hot-air, makes the temperature of indoor environment more uniform in the vertical direction, and improve
Heating efficiency.Such as first breeze fan 120 revolving speed can be rated speed 30%, the revolving speed of the second breeze fan 130 can
It is the 90% of rated speed；The revolving speed of first breeze fan 120 can be the 25% of rated speed, and the second breeze fan 130 turns
Speed can be the 100% of rated speed；The revolving speed of first breeze fan 120 can be the 20% of rated speed, the second breeze fan 130
Revolving speed can be rated speed 95% etc..
In the case where the air humidity of outdoor environment is less than default humidity threshold, when indoor heat exchanger 140 is in heating
When state and outdoor environment temperature are less than indoor environment temperature, the revolving speed of the first breeze fan 120 can be the 90% of rated speed
~100%, the revolving speed of the second breeze fan 130 can be the 20%~30% of rated speed, to make by 112 He of the first air outlet
While the gas flow temperature of second air outlet 113 blowout is uniform, the temperature difference of indoor environment is reduced in the vertical direction.Such as first
The revolving speed of breeze fan 120 can be the 90% of rated speed, and the revolving speed of the second breeze fan 130 can be the 30% of rated speed；
