Ventilation is the process of exchanging used air for fresh, which is necessary for the safe functioning of people and the proper working of devices that use air in residential, office, and manufacturing spaces. This is especially important in situations where additional pollutants are present, such as: cigarette smoke, chemical vapors, dust, etc.
Heat recovery, also known as mechanical ventilation is a process of waste heat recovery with a heat exchanger (recuperator). A recuperator controls the inbound and outbound air flow in a room while recovering heat from the air expelled from a building.
