The evaporator 1 is disposed between the upper duct 5 and the lower duct 6, so that the upper duct 5 and the lower duct 6 are separated from each other. Namely, the evaporator 1 is arranged between the first fan 7 and the second fan 8, and the upper air duct 5 and the lower air duct 6 are arranged up and down relatively.
The first fan 7 and the second fan 8 are cross-flow fans.
The air conditioner aims to solve the problems of large vertical temperature difference of refrigeration and heating, no warm foot heating and cold air blowing. The tail end of the upper volute 31 is connected with an upper diffusion baffle 10, and the tail end of the lower volute 32 is connected with a lower diffusion baffle 11.
Specifically, the upper diffuser 10 rotates around the end axis of the upper volute 31; the lower diffuser plate 11 rotates about the end axis of the lower volute 32.
The upper air duct 5 is provided with a first air opening 51, the lower air duct 6 is provided with a second air opening 61, and both the first air opening 51 and the second air opening 61 have air inlet and outlet functions. Namely, when the air conditioning indoor unit heats, the first air port 51 is an air inlet, and the second air port 61 is an air outlet; when the indoor unit of the air conditioner refrigerates, the first air opening 51 is an air outlet, and the second air opening 61 is an air inlet.
Specifically, the air outlet fan blade rotates as an active fan blade, the air inlet fan blade rotates at the optimal rotating speed matched with air outlet according to a two-stage supercharging air inlet technology, the air inlet fan blade drives the air inlet fan blade to enter the air channel after secondary supercharging, supply of the air inlet fan blade is increased, air outlet capacity of the whole machine is improved, and the highest air speed of the air outlet reaches 7m/s (generally 5-6m/s), so that heat exchange efficiency of the evaporator 1 is effectively improved.
More specifically, when the air conditioner heats, air enters the first air opening 51, air exits the second air opening 61, hot air falls to the ground from the range of 0.5m to 5.5m, reaches the wall from the ground by utilizing the wall attachment effect of air flow and then rises to the roof, and then enters the air conditioner again by utilizing the negative pressure of the inlet air to exchange heat, so that the large circulation flow of the air in the whole house is realized, and the room temperature is more uniform. The deviation of the heating temperature is only 1.811 ℃, the temperature difference of the normal activity area of the human body is within 1 ℃ (the existing wall hanging machine is 4.7381 ℃), and the problem of large vertical heating temperature difference is thoroughly solved.
During refrigeration, air enters the second air port 61, air exits from the first air port 51, cold air is naturally deposited from a roof, enters the air conditioner again for heat exchange under the action of the air inlet negative pressure of the second air port 61, indoor air circulation flow is accelerated, the distance from the air conditioner is 6m, the air supply speed in a normal movement range of a human body is below 0.3m/s, the refrigeration temperature deviation is only 0.441 ℃ (the existing wall-mounted unit is 1.551 ℃), a person can not feel cold air when playing a face, only feel natural and comfortable cold air, the soft cooling of the whole room is realized, and the problem that the person blows cold air is thoroughly solved.
The air outlet surge problem is solved when the upper and lower fans rotate at different rotating speeds in a matching way when the upper and lower fans are bidirectionally reversible. An upper diffusion baffle 10 and a lower diffusion baffle 11 which can rotate around an axis are respectively added at the diffusion sections of the upper air duct 5 and the lower air duct 6, the upper diffusion baffle 10 and the lower diffusion baffle 11 flexibly adjust the angle of the diffusion baffles according to different windshields and adapt to the air outlet pressure of different windshields, so that the surge of each windshield is minimized.
Specifically, as shown in fig. 2, when the air conditioner is lower than a low wind speed (including the low wind speed), the diffuser is in a closed state, at this time, since the rotation speed of the fan is low, the air inlet fan is not moved, the air outlet fan is rotated, at this time, the air volume is small, the diffuser is in a closed state, the air outlet angle is increased, and the air volume is increased; when the air conditioner is at the medium wind speed, the diffusion baffle is opened by 25 degrees, the air inlet fan rotates at a lower rotating speed at the moment, the air inlet amount is increased in an auxiliary mode, the angle of the opened part of the diffusion baffle is increased, the air outlet is more concentrated, and the air amount is increased (when the medium wind speed is reached, the 25 degrees of the opened diffusion baffle is compared with the closed state of the diffusion baffle, the air amount is increased by 32-38m3) The slight eddy surge noise caused by auxiliary air inlet of the air inlet fan is reduced; when the air conditioner is in a high wind speed (including a high wind speed), the diffusion baffle is opened to the maximum angle of 50 degrees, the air inlet fan performs auxiliary air inlet at the speed of 700n/s, the air outlet angle is further reduced at the moment, so that high-speed flowing air flow is pressurized at the air outlet, and the air quantity is increased (compared with the closed state of the air channel baffle, the air quantity is increased by 58-63m3) Meanwhile, because the air flow at the air outlet is concentrated, the noise caused by the collision of the turbulent air flow can be effectively reduced, and the surging noise of the fan caused by the up-down reversible air outlet is effectively avoided.
In order to solve the problem of low-speed surge caused by long and narrow air channels of the bidirectional reversible upper and lower air outlet channels, the microporous panel 2 is arranged to form a film micropore effect, so that closed low-frequency and wide-frequency cavity sound easily generated in the long and narrow air channels is effectively released, airflow vortex in the air channels is broken, noise energy which is continuously reflected and amplified by resonance in the long and narrow air channels has countless fine release openings, and is released to the outside through the film micropores, and because the sound-absorbing sponge is adhered outside the microporous panel 2, the noise is effectively reduced; and meanwhile, the sponge is adhered on the outer side to cover the micropores, so that the air leakage of the air duct is avoided while the heat is preserved. The density and size of the micro-holes are determined according to the experimental conditions of a specific air duct.
And because the diffusion baffle is longer in overall size, in order to prevent deformation, the diffusion baffle is integrally divided into a plurality of sections of diffusion plates.
Specifically, the upper diffusion baffle 10 is provided with a plurality of first diffusion plates which are connected into a whole through a rotating shaft; the lower diffusion baffle 11 is provided with a plurality of second diffusion plates which are connected into a whole through a rotating shaft.
