- •
Mach number on multi-stage perforated plates in HPRV is investigated.
- •
Design method of multi-stage perforated plates for HPRV is proposed.
- •
Influence area of the last perforated plate is larger under higher pressure ratio.
- •
Energy loss of the perforated plate is larger than the valve core.
- •
There is a limited pressure ratio of every perforated plate expect the last one.
