Abstract: A heat recovery ventilator is provided which includes a heat exchanger having discrete inlet and exhaust passageways extending therethrough for providing heat transfer between respective fluids flowing along the inlet and the exhaust passages. The inlet passageway provides fluid communication between a supply inlet plenum and a supply discharge plenum. The outlet passageway provides fluid communication between an exhaust inlet plenum and an exhaust discharge plenum. The supply inlet plenum has a supply port for admitting supply air into the supply inlet plenum. The exhaust discharge plenum has an exhaust port for discharging air from the exhaust discharge plenum. A transfer port extends between the supply inlet plenum and the exhaust discharge plenum for providing fluid communication therebetween.

Abstract: In a heat recovery ventilator, a housing has an inlet and an outlet for a first fluid flow and an inlet and an outlet for a second fluid flow, and has a heat exchange panel assembly having two sets of panels alternately arranged to form a first and a second flow path for each of the first fluid flow and the second fluid. The first flow path is in fluid communication with the first fluid flow inlet and outlet and the second flow path is in fluid communication with the second fluid flow inlet and outlet. The heat exchange panel is slidably mounted within the housing. A first fan and a second fan is mounted on a fan mounting plate. The fan mounting plate is hingedly mounted to the housing and is pivotable between a servicing position and an operational position.
