fully mechanical ventilation system, the application of air-to-air heat exchanger
technology is vastly beneficial anywhere in Europe. Mind that this scenario is only
valid when mechanical ventilation is necessary anyway and with high-end HRUs that
combine a high thermal effectiveness (e = 0.8) and low pressure drop.
4.5 Demand-Controlled and Hybrid Ventilation
By modulating the ventilation flow rate to the pollution load, thus providing
ventilation if and when needed, the ventilation heat loss can also be considerably
reduced (Mansson
1993
). In order to do this efficiently, sensors are usually used to
