Abstract

The invention provides an indoor unit and an air conditioning system. The indoor unit comprises an air duct and a cross flow fan blade arranged in the air duct. The air duct comprises a first flow guide wall and a second flow guide wall arranged oppositely; the air duct is provided with an air outlet, the diameter of the cross flow fan blade is D, the length of the air outlet is L2, the width of the air outlet is a1, the width of the air outlet is the minimum distance from the inner wall surface of the first flow guide wall and the inner wall surface of the second flow guide wall, and the relationship between D and L2 meets the condition: D=a*L2-b*L2<^2>-c; and / or the relationship between D and L1 meets the condition: D=d*a1-e*a1<^2>+f*a1<^3>-g, wherein a is ranged from 2.85 to 2.95; b isranged from 1.51*10<^-3> to 1.61*10<^-3>; c is ranged from 1241.3 to 1261.3; d is ranged from 702.3 to 710.3; e is ranged from 6.05 to 6.15; f is ranged from 0.0171 to 0.0183; and g is ranged from 27100 to 27300. The indoor unit provided by the invention can guarantee the air out performance of an air conditioner and reduce the air out noise.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an indoor unit and an air conditioning system. Background technique [0002] For traditional wall-mounted units and some vertical air conditioners, cross-flow fans are generally used to supply air. The unreasonable design of the air duct structure will not only affect the air outlet performance of the air conditioner, but also generate relatively loud noise. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to provide an indoor unit and an air conditioning system, which can effectively ensure the air outlet performance of the air conditioner and reduce the air outlet noise. [0004] In order to solve the above problems, the present invention provides an indoor unit, which includes an air duct and cross-flow fan blades arranged in the air duct, the air duct includes a first guide wall and a second g...
