Detailed Description
As shown in fig. 1, the air supply system for the indirect evaporative cooling air conditioner comprises a multi-fan air duct 1, wherein the multi-fan air duct 1 comprises a fan cavity 11 and an air outlet channel 12 which are communicated with each other at a certain angle, and a plurality of fans 2 are arranged in the fan cavity 11 at intervals side by side along the width of the fan cavity. Thus, the fans 2 suck air from the air suction ports facing the reader shown in fig. 1, and discharge the air from the air discharge ports facing away from the reader, and then the blown air is collected upward to the air outlet channel 12 communicated with the fan cavity 11 and discharged through the air outlet of the air outlet channel 12.
And an air partition plate 3 is arranged between every two adjacent fans 2, one end of the air partition plate 3 is fixedly connected with the front end of the fan cavity 11, and the other end of the air partition plate is bent in an arc shape and faces the air outlet of the air outlet channel 12. The wind partition plate 3 is arranged to prevent wind blown out by adjacent fans from interfering with each other, and the arc-shaped bending of the wind partition plate 3 is beneficial to smooth blowing out of the wind blown out by the fans, so that the blowing-out resistance is reduced.
Two sides of each fan 2 are respectively provided with a concave arc-shaped air deflector 4, one end of each air deflector 4 is connected with the air partition plate 3, and the other end of each air deflector is connected with the bottom of the fan cavity 11. The air deflector 4 reduces the eddy current at the dead angle formed by the air baffle 3 and the bottom of the fan cavity 11, improves the fan efficiency, and reduces the fan power consumption and noise.
Generally, the blower cavity 11 and the air outlet channel 12 are arranged vertically, which is convenient for installation.
Referring to fig. 2 to 4, which are schematic structural views illustrating the multi-fan duct for use in an indirect evaporative cooling air conditioner, the multi-fan duct 1 is disposed on the air supply side of the whole air conditioning system, and the air inlet system 5 is disposed on both sides of the air-air heat exchanger 6, and a plurality of fans 2 are disposed side by side in a fan chamber 11 along the length direction of the air-air heat exchanger 6. When the air supply system sends high-temperature indoor return air into the air-air heat exchanger 6 through an air supply outlet, the high-temperature indoor return air in the air-air heat exchanger 6 exchanges heat with outdoor low-temperature air introduced into the air-air heat exchanger to be cooled and then is sucked in through the fans 2, then each fan 2 blows out the cooled indoor return air, the indoor return air is converged into the air outlet channel 12 and then is sent into the room, temperature-controlled indoor circulation is completed, the outdoor low-temperature air in the air-air heat exchanger 6 exchanges heat with the high-temperature indoor return air and then is discharged out of the room, and the temperature-controlled outdoor circulation is.
The air supply system is suitable for being used in the situation that the installation space of the indoor air supply opening is insufficient, the installation direction of the air supply opening needs to be changed at the moment, usually, a plurality of fans are arranged in the fan cavity along the length direction of the air-air heat exchanger 6 in the lateral direction, therefore, when the number of the fans needs to be increased, the fans only need to be arranged along the length direction of the air-air heat exchanger 6, the air outlet channel 12 of the air supply system is perpendicular to the length direction of the air-air heat exchanger 6, the size of the air supply opening is reduced by the arrangement mode, and the air outlet of the air supply system can be installed in a narrow space.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
