VENTILATION DEVICE AND VENTILATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/259022
Kind Code:
A1
Abstract:
Disclosed in the present invention are a ventilation device and a ventilation system. The ventilation device comprises: a ventilator, provided with two ports in the axial direction; a fan, provided in the ventilator so as to enable airflow to pass through the ventilator; and a heat regenerator, provided in the ventilator and used for absorbing heat in the airflow. A blocking part used for blocking airflow is formed on the periphery of the fan in the radial direction, and the blocking part is used for enabling the circulation cross section of the fan to be smaller than that of the heat regenerator. According to the present invention, the circulation cross section of the fan is set to be smaller than that of the heat regenerator, thereby forming reasonable pressure matching and flow velocity matching between the fan and the heat regenerator.
