Classification of fresh air systems

1. Positive pressure air supply system, which only has an air inlet, can directly install an outdoor unit at the air inlet to deliver fresh air indoors.

2. A unidirectional fresh air system, which installs a fan behind the exhaust duct to generate pressure and continuously deliver fresh air indoors. Installed in the bathroom or kitchen, it can exhaust the turbid indoor air through the exhaust outlet and is also a good fresh air system.

3. Compared with unidirectional flow, bidirectional flow has more comprehensive functions, and there are also two types, one is cold and hot exchange, which can recover 70% of the heat. There is also a type that does not have hot and cold exchange, which is quite popular in the market and has many advantages because the air exchange volume is relatively large.
