Ventilation Energy Recovery Ventilator
Heat exchange ventilation and normal ventilation
Adopts a highly efficient counter-flow heat exchange element
Heat exchange ventilation
When a room is cooled or heated, the exhausted cooling / heating energy is recovered by heat-exchange ventilation.
This is used in the spring and autumn, when rooms are not cooled or heated, that is, when there is little difference between the indoor and outdoor air conditions. In addition, at night during the hot season, when the outside air temperature drops the outside air is drawn inside without heat exchange, alleviating the load on the air conditioning equipment.
Energy efficiency and ecology
Energy consumption is dramatically reduced by using a counter-flow heat-exchange element. Air conditioning load is reduced by approximately 20%, resulting in significant energy savings. Recovers up to 77% of the heat in the outgoing air.
Features of heat exchange element
With the cross-flow element, air moves in a straight line across the element. With the counter-flow element, air flows through the element for a longer time (longer distance), so the heat-exchange effect remains unchanged.
Significantly reducing low pressure loss and noise allows low-noise operation.
Extended range of an external static pressure
An external static pressure is improved by adopting a powerful fan motor.
This allows for application in a wide variety building.
Easy Installation and Maintenance
Slim shape and easier installation
Counter-flow heat exchange element used for reduced noise and slimmer, more compact body shape.
Reverse mountable direct air supply / exhaust system
Adoption of straight air supply / exhaust system: Duct design is simplified because the air supply / exhaust ducts are straight.
Since each unit can be mounted in reverse position, only one inspection hole is needed for two units: Two units can share one inspection hole so duct work is easier and more flexible.
