specific Embodiment 2
[0042] When the indoor mechanism of the air conditioner is heated, the upper switch door of the air outlet grille on the upper front panel is opened, and the lower switch door of the left outlet grille on the lower front panel is also opened, and at the same time, the fan speed of the upper volute fan and the lower volute fan are adjusted. The rotation speed of the upper volute fan is adjusted and controlled so that the fan speed of the upper volute fan is lower than the fan speed of the lower volute fan, so that the air enters from the left inlet grille of the upper front panel and the right inlet grille of the upper front panel, and passes through the indoor unit. After the heater, most of the hot air is sent out from the left outlet grille of the lower front panel, and a small part of the hot air is sent out from the outlet grille of the upper front panel, which ensures that most of the hot air is sent to the lower space of the room, and can also Taking care of the demand fo...
specific Embodiment 3
[0043] When the indoor unit of the air conditioner is cold, the upper switch door of the outlet grille on the upper front panel is opened, the lower switch door of the left outlet grille on the lower front panel is closed, and at the same time, the upper volute fan is controlled to open, and the lower volute fan is turned off. At this time, the indoor air enters from the left air intake grille of the upper front panel, the right air intake grille of the upper front panel, and the forward air grille of the upper front panel. Sending out, all the circulating cold air is directly sent to the upper space of the room, so that the cold air sinks to lower the temperature of the lower room, which improves the comfort of the air conditioner.
specific Embodiment 4
[0044] When the indoor unit of the air conditioner is cold, the upper switch door of the air outlet grille on the upper front panel is opened, and the lower switch door of the left outlet grille on the lower front panel is also opened, and at the same time, the speed of the upper volute fan and the lower volute fan are electronically controlled. The transfer of the fan is adjusted so that the speed of the upper volute fan is greater than that of the lower volute fan, so that the air enters from the right inlet grille of the upper front panel, and after passing through the heat exchanger of the indoor unit, most of the hot air flows from the upper front The air outlet grille of the panel is sent out, and a small part of hot air is sent out from the left air outlet grille of the lower front panel and the right air outlet grille of the lower front panel, which ensures that most of the cold air is sent to the upper space of the room, and can also take care of The demand for heat in...
