Patent attributes
A ventilation wall system has an air intake end for air entering and an air exhaust end for air exhausting. The ventilation wall system includes a heat exchanger module, a fan module, an electric control module, and an air filter module. The heat exchanger module is configured to exchange heat for air entering the heat exchanger module. The fan module is configured to convey air on one side of the fan module to the other side of the fan module. The electric control module is electrically connected to the fan module and the heat exchanger module. The air filter module is configured to filter air entering the air intake end. When the fan module is disposed on a side that is of the heat exchanger module and that is close to the air exhaust end, air after heat exchange performed by the heat exchanger module is sent out.
