Description

Technical Field

[0001] The utility model relates to the field of air treatment, in particular to a thin vertical wall-mounted U-shaped air treatment unit. Background Art

[0002] Combined air-conditioning units can be divided into two categories according to the installation form: horizontal and vertical. Horizontal units occupy a large area, are relatively small in height, and have low utilization of the height space of the machine room. Vertical units have improved floor space, but the positions of the fresh air inlet and return air inlet are relatively low. When the air volume of the unit is small, it does not conform to the positioning of the air duct in the air-conditioning place. Therefore, an air handling unit is needed that can not only ensure the air volume of the unit, increase the air volume of the unit, but also reduce the floor space and improve space utilization. Utility Model Content
