Title:
BYPASS STRUCTURE, VENTILATION DEVICE AND VENTILATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/092474
Kind Code:
A1
Abstract:
Disclosed are a bypass structure, a ventilation device, and a ventilation method, wherein the bypass structure is used for the ventilation device. The bypass structure is disposed in parallel with a primary ventilation structure in the ventilation device. The bypass structure comprises a fresh air bypass passage (8) and a discharge air bypass passage (9), which are independent from each other. The fresh air bypass passage (8) is configured to provide a flow passage for outdoor fresh air flowing through the ventilation device from the outdoor side to the indoor side, and the discharge air bypass passage (9) is configured to provide a flow passage for indoor discharge air flowing through the ventilation device from the indoor side to the outdoor side. A first airflow gate (51) is provided in the fresh air bypass passage (8) and a second airflow gate (52) is provided in the discharge air bypass passage (9), for opening or closing the fresh air bypass passage (8) and the discharge air bypass passage (9), respectively. With the bypass structure, the bypass ventilation efficiency is improved, and a pressure difference between the indoor side and the outdoor side can be eliminated, avoiding unfiltered air from directly entering the indoor side and reducing wear and tear of the primary ventilation structure. The ventilation device and method use the bypass structure in ventilation, reducing wear and tear of the primary ventilation structure.
