Abstract

The invention discloses a new wind machine. The new wind machine comprises a shell, a heat exchange core, a first air flue piece and a first fan assembly; the shell is provided with a first side wall;the heat exchange core is provided with a first air flow passage and a second air flow passage which are spaced apart from each other, the air inlet end of the first air flow passage is in communication with a fresh air inlet, and the air outlet end of the second air flow passage is in communication with a return air outlet; and the first fan assembly is located between the first side wall and the first air flue piece, and the first fan assembly includes a first centrifugal wind wheel, wherein the minimum distance between the rotation center line of the first centrifugal wind wheel and the first side wall is D1, the minimum distance between the first air flue piece and the first side wall is E1, and the D1 and the E1 satisfy the condition that 0.6< / =[(E1-D1) / D1]< / =1.4. According to the new wind machine, the exhaust air rate of the new wind machine can be increased, and the working noise can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a new fan. Background technique [0002] In related technologies, when the fresh air blower is working, the wind resistance in the air duct of the fresh blower is large, which causes the air volume of the fresh blower to decrease and the noise to increase, which affects user experience. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a new fan, which can increase the exhaust air volume of the fresh fan and reduce the working noise. [0004] The fresh air blower according to the embodiment of the present invention includes: a housing having a fresh air inlet, a fresh air outlet, a return air inlet and a return air outlet, the housing having a first side wall; a heat exchange core, the heat The exchange core is arranged in the housing...
