I see more push / pull ventilation systems with heat recovery coming. This solution is with a regenerative ventilation principle.
The product works by sucking air out through a regenerator (heat accumulator). Dirty air is sucked out for eg 60 seconds. Then the fan changes direction of rotation and now blows in fresh air which is passed through the regenerator and heated.
I am interested in simulating this process. This means that I have an inlet that after 60 seconds becomes an outlet. I also think the approach should be a transient simulation.
Another challenge is to involve heat recovery. At the beginning of the course the supply air temperature will be high and at the end of the process the supply air temperature is reduced, is there any here who have an idea of how this is set up in the simulation??
