STRUCTURE AND OPERATING LOGIC
Fig. 2. Unit structure and operating logic
The unit has the following operating logic (fig. 2):
Warm stale extract air from the room flows through the air ducts to the unit, is purified in the extract filter and is supplied to the heat recovery core and exhausted outside
by exhaust fan. Clean cold air from outside is moved by supply fans to the unit where it is purified through the supply filter. Then clean air flows through the heat recovery
core and is supplied to the room by supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air and warms it up. The extract and intake air flows are fully separated during heat recovery which
excludes any transfer of odors and pathogens to supply air. Heat recovery minimizes thermal energy losses, energy demand and heating costs.
