Problems solved by technology

[0003] The damper structure is driven by the motor to move the damper attached to the tuyere. After the damper has been in operation for a long time, the hinges may be rusted and loosened, and may be stuck during the movement.
In addition, when the damper is closed, there is inevitably a gap between the damper and the tuyere, so it is difficult to achieve a better sealing effect
Moreover, the large volume of the air valve structure also makes it difficult to install more air valves in the fresh air unit for combination to flexibly realize various functions

Abstract

The invention relates to an air flue assembly and a fresh air unit. The air flue assembly comprises an air flue, a sealing element (7) arranged in the air flue and made of a flexible material, and a sealing state adjustment part for actively adjusting a state of the sealing element (7) so as to enable the air flue to close when the sealing element (7) is in contact seal with a side wall of the airflue and enable the air flue to open when the sealing element (7) is not in seal with the side wall of the air flue. According to the air flue assembly and the fresh air unit provided by the invention, the flexible sealing element is adopted and can tightly fit to a sealing surface under the control of the sealing state adjustment part, and the flexible sealing element can eliminate a contact gapthrough self-deformation, so that a contact pre-tightening force is increased, and a sealing effect is optimized. In addition, a sealing structure is more reliable compared with an air valve structure, and cannot be invalided easily after long-time use. In addition, the air flue assembly can further adapt to various conditions such as planes and irregular surfaces, is higher in adaptability, andcan be beneficial to reducing the requirement on the processing precision on the side wall of the air flue.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a fresh air unit. Background technique [0002] Fresh air haze removal devices are currently widely used in civil comfort occasions such as green buildings, transportation hubs, education and medical treatment. Fresh air units currently on the market usually use a damper structure to open and close the air duct to switch between different working modes such as full heat exchange function, bypass or internal circulation function. [0003] The damper structure is driven by the motor to move the damper attached to the tuyere. After the damper has been in operation for a long time, the hinges may be corroded and loose, and may be stuck during the movement. In addition, when the damper is closed, there is inevitably a gap between the damper and the tuyere, so it is difficult to achieve a better sealing effect. Moreover, the large volume of the air valve structure also makes...
