Air duct assembly of air handling equipment and air handling equipment

Abstract

The invention discloses an air duct assembly of air handling equipment and the air handling equipment. The air duct assembly comprises a foam air duct piece, a filtration device and a heat exchange core body. An air return flow path and an air inlet flow path are arranged in the foam air duct piece, the air return flow path comprises an air return inlet air duct and an air return communicating airduct, the air inlet flow path comprises an air inlet air duct and an air inlet communicating air duct, the filtration device is arranged in the air inlet flow path, air flow in the air inlet flow path and the air return flow path exchanges heat in the heat exchange core, in the vertical direction, the length of an inlet end of the air inlet air duct is H, the length of an outlet end of the air inlet air duct is h, the length of an inlet end of the air return inlet air duct is D, the length of an outlet end of the air return inlet air duct is d, and the air inlet air duct and the air return inlet air duct meet the relation formula: h is greater than or equal to 0.3 / H is less than or equal to 0.7 and / or d is greater than or equal to 0.3 / D is less than or equal to 0.7. According to the air duct assembly of the air handling equipment, the action of noise reduction and increasing air quantity can be achieved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the field of air treatment equipment, in particular to an air duct assembly of the air treatment equipment and the air treatment equipment. Background technique [0002] In the related art, the air handling equipment is equipped with a foam air channel structure for air guidance, but the flow resistance of the air flow in the foam air channel structure is relatively large, which not only increases the working load of the air guiding fan, but also reduces the air handling equipment. The air volume is high, and the noise generated by the air flow is relatively large, which greatly reduces the user's comfort. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide an air duct assembly for air handling equipment, which has the advantages of reasonable structural arrangement, increased air v...
