Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, first embodiment of the invention proposes a kind of air conditioner room unit, be specially a kind of ceiling type air conditioner indoor unit, this indoor set comprises housing 10, housing 10 surrounds air inlet 20, air outlet 21, be arranged on the heat exchanger 50 in housing 10, also comprise the first blower fan 30, second blower fan 31, controller (not shown) and controlled, drive the first rotating speed controllable motor (not shown) of described first blower fan 30 and drive the second rotating speed controllable motor (not shown) of described second blower fan 31 by described controller; Wherein:
Housing 10 and outside such as roof 60 is fixedly connected with; Described first blower fan 30 is arranged in the first air channel 40, and described first air channel 40 is communicated with corresponding air inlet 20 and air outlet 21; Described second blower fan 31 is arranged in the second air channel 41, and described second air channel 41 is communicated with corresponding air inlet 20 and air outlet 21; This first blower fan 30 and the second blower fan 31 are cross flow fan, and two blower fans 30,31 form two cross flow fan thus, have air channel structure 70 between two blower fans 30,31.
Described first rotating speed controllable motor is connected with controller by the first control line of adjustable rotating speed, and described controller controls the rotating speed of the first rotating speed controllable motor by the first tachometer value of setting;
Described second rotating speed controllable motor is connected with controller by the second control line of adjustable rotating speed, described controller controls the rotating speed of the second rotating speed controllable motor, to make the air quantity in described first air channel 40 and the second air channel 41 same or equivalent by second tachometer value being different from described first tachometer value of setting.
Particularly, in the present embodiment, first blower fan 30 and the second blower fan 31 are cross flow fan, its Shang Liang air channel, cross section perpendicular to axial direction is symmetrical, the symmetrical flow resistance of air-supply passage that makes is similar, namely can realize the same or equivalent technique effect of the air quantity in the first air channel 40 and the second air channel 41 by less adjustment of rotational speed.
As a kind of embodiment, above-mentioned two air channels are symmetrical can be: the air intake passage of the corresponding described heat exchanger left and right sides, two air channels is identical;
