Ventilation system with enthalpy heat exchanger
An 800 m³/h ventilation system with heat recovery as enthalpy heat exchanger was installed on each floor of the office building. Heat exchangers with membranes transfer both temperature and humidity to ensure a pleasant room climate. The system ensures pollen and dust-free supply air, an optimal oxygen supply and minimisation of external noise pollution. The system saves over 50% of heating and cooling energy.
Energy requirement without / with heat recovery
- Energy requirement for heating without: 18,631 kWh/a with: 9300 kWh/a
- Energy requirement cooling without: 6,813 kWh/a with: 3400 kWh/a
- Heat output without: 41.2 W/m² with: 18.7 W/m²
- --> 50% energy saving
Working principle (procedure)
Summer: Cooling of the warm outside air + humidity compensation
Winter: Warming up the cold outside air + humidity compensation
