air conditioner

Abstract

The invention provides air conditioning equipment which comprises a shell, a volute air flue, a wind wheel and a heat exchanger. The shell is provided with an air return opening and an air exhaust opening; the volute air flue comprises a volute part and a volute tongue part, the volute part is provided with an abutting edge, and the abutting edge is in contact with the inner end of the exhaust opening; the wind wheel is a cross flow wind wheel, the wind wheel is located in the volute air flue, a molded line of the volute part and the abutting edge have an intersection point, and the length F1of a line from the point closest to the wind wheel to the intersection point on the molded line, the hole wall length F2 of the exhaust opening, the wind wheel diameter D and the wind wheel axial length L meet the conditions that 1.8<=(F1+F2) / D<=2.5, and 3.5<=L / D<=4.6; and the heat exchanger is crossed with a horizontal tangent plane of the lower end point of the wind wheel, and the heat exchangeris provided with a plurality of heat exchange pipes, wherein the number of the heat exchange pipes located on the upper side of the horizontal tangent plane is smaller than the number of the heat exchange pipes located on the lower side of the horizontal tangent plane. According to the air conditioning equipment in the scheme, the flat and smooth airflow flow line in the volute air flue can be achieved, the aims of reducing the airflow noise and reducing airflow losses are achieved, and the product noise reduction effect and energy efficiency can both be improved.

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.
