Air conditioning equipment

Abstract

The invention provides air conditioning equipment which comprises a shell, a volute air duct and a wind wheel, wherein the shell is provided with an exhaust port and a return port, and the area A of the air return port and the area B of the exhaust port meets the following relationship: A / B is greater than or equal to 2.5 but less than or equal to 3.5; the volute air duct is located in the shell and communicates to the exhaust port and the air return port, the volute air duct comprises a volute part and a volute throat part, the volute part is provided with a leaning edge, and the leaning edgeis in contact with the inner end of the exhaust port; the fan is a cross-flow wind wheel which is located in the volute air duct, the intersection line formed by intersecting the inner surface of thevolute part and the middle section vertical to the axis of the wind wheel is a molded line of the volute part, the molded line and the leaning edge have an intersection, and the line length L1 of themolded line from the point nearest to the wind wheel to the intersection, the hole wall length F2 of the exhaust port and the diameter D of the wind wheel meet the following relationship: (F1+F2) / D is greater than or equal to 1.8 but less than or equal to 2.5. According to the air conditioning equipment provided by the scheme, the airflow in the volute air duct is smooth and unhindered in flow line, so that the purposes of reducing the noise of the air flow and reducing the resistance loss are achieved, and the noise reducing effect and the energy efficiency of a product are enhanced too.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner. Background technique [0002] Existing air conditioners such as window air conditioners and mobile air conditioners are equipped with indoor side wind wheels to drive air circulation. In the process of realizing the present invention, the inventor found the following problems in the prior art: when the existing air conditioners are running, There are problems such as unstable wind sound and loud noise on the indoor side, which leads to poor product experience, and leads to low overall energy efficiency and high energy consumption of air-conditioning equipment. Contents of the invention [0003] In order to solve at least one of the above technical problems, the purpose of the present invention is to provide an air conditioner. [0004] In order to achieve the above object, an embodiment of the present invention provides an air conditioner, including:...
