waste heat recovery system

ygroscopic and non-hygroscopic or for recovering and transferring heat and possibly moisture from the exhaust air to supply air

Plate heat exchanger is made out of aluminum, or optionally stainless steel or polycarbonate, plates and turbulence channels.

Special sealing maintains separated supply flow and exhaust flow.

Once again, a heat exchanger is used to transfer heat to the air in the ventilation ducts

There are various forms of HVAC systems, however they all operate based off the same thermodynamic principles.
