Development of applications for energy efficient demand controlled hybrid ventilation in dwellings

The goal of this project is to develop a Danish concept for hybrid ventilation combined with demand control for dwellings. This will be done based on development of new, more efficient components. This includes components such as electronics for controlling the ventilation, wireless sensors, actuators for regulation of inlet grilles as well as integration of solar cells. Demand control at the inlets secures an optimal distribution of fresh air in the dwelling, which, in turn, will reduce problems with discomfort (draught) as overventilation in periods of strong wind loads or large temperature differences is reduced. The focus in the project is on development of an economically attractive decentral control and electricity supply of the hybrid ventilation, where PV stand-alone solutions are integrated to form a unit which is easy to handle for both the craftsman and the user. A PV stand-alone solution requires no cabling to the individual components, resulting in a much more flexible installation when deployed with wireless control systems.
