STRUCTURE AND OpERATINg LOgIC
The unit operating principle is as follows (fig. 2). Warm stale air from the premises extracted by the unit is purified in the extract filter,
then it passes through the heat exchanger and then is exhausted outside through the ducts by the exhaust fan.
Clean cold intake air supplied to the unit is purified in the supply filter.
The air passes through the heat exchanger and then fed into the premises by the supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. The air flows are fully separated.
Heat recovery minimizes thermal energy losses, energy demand and operating costs for heating during winter time.
The unit is equipped with a posistor 350 W electric heater to enable supply air warming up. The heater has overheating protection.
