Fujitsu energy recovery ventilation efficient and ecological solution

Fujitsu energy recovery ventilation

What is energy recovery ventilation? In simple words, when a room is cooled or heated, the exhausted cooling or heating energy is recovered by heat-exchange ventilation. Normal ventilation is used in the spring and autumn, when rooms are not cooled or heated. This means that when there is little difference between the indoor and outdoor air conditions. For example, 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 recovery ventilation 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 that 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.

  • More comfort due to quiet operation. Using energy recovery ventilation, it significantly reduce low pressure loss and noise allows low-noise operation.
  • Design flexibility with the extended range of an external static pressure. An external static pressure is improved by adopting a powerful fan motor. This allows for application being used in a wide variety building.

Fujitsu energy recovery ventilation easy to install and maintain

Due to slim shape it is easier to install these applications. 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.
