Simulation the effectiveness of heat recovery of the regenerative ventilator using different approaches

Today buildings should be designed for energy efficiency class not less than C. This requires ventilation with heat recovery. On the market, there are different compact recovery units decentralized ventilation. Regenerative ventilators represent a promising area of effective exhaust air They operate cyclically inlet and outlet air. These kinds work in blocked pair(s) – one input output each pair. If not, effectiveness will decrease. A mathematical model ceramic regenerator regenerative ventilator “Twin Fresh” by Vents has been created to improve its operation. In previous works, on basis two approaches, operation was simulated. The first uses M. Mikheev’s formula Nusselt number. second is computational fluid dynamic simulation SolidWorks Flow Simulation. coefficients obtained as result had significant difference up 66.5 %. aim find alternative methods adequately determining ventilator. performed using from “Novyi spravochnik khimika i tekhnologa. Protsessy aparaty khimicheskikh tekhnologii”. takes into account Grashof Values significantly both ones times. There no information literature about experimental conditions number, which used simulation. Therefore, we can’t assume, what approach closer regenerator. need conduct studies determine exchanger.
