1 Unit design
Use
The Danfoss Vent heat recovery unit is used for transporting air according to ELSÄK-FS 1999:5-Group B,
i.e. not for transporting flammable and explosive substances, grinding dust and similar. When ventilating
residential buildings, Danfoss Vent transfers the energy in the extracted air to heat transfer fluid in a heat
pump, therefore increasing the heat pump’s heating factor.
Casing
The Danfoss Vent heat recovery unit is made up of dual galvanized plates with intermediate condensation
and sound insulation. The outer casing is available in steel plate and powder-coated versions.
Filter
The unit is equipped with a non-washable G80 filter to protect the fan and the heat recovery coil from
blockages. A filter sensor indicates when the filter must be inspected. Use a vacuum cleaner to clean the
filter. We recommend replacing the filter once a year.
Heat recovery unit
The hot extracted air passes a water coil and transfers its heat to the water that comes from the ground or
rock collector etc. The transferred energy supplies the cold side of the heat pump and therefore increases
the heat factor of the heat pump.
Fan
The Danfoss Vent heat recovery unit has a radial fan with forward angled blades and an external rotor
motor with integrated thermal switch.
Circulation pump
Danfoss Vent has an integrated circulation pump.
Control system
Danfoss Vent’s control equipment is located on the front of the unit. The control unit regulates the fan
capacity from 20%-99%, continuous control of the circulation pump, pump stop during defrost and indica-
tes when the filter needs inspecting.
Connections
The duct connections of the Danfoss Vent heat recovery unit are 160 mm in size with the extracted air to
the right and the exhaust air to the left, seen from the front of the unit.
