The VAM HRV units provide for cost effective energy efficient
fresh air ventilation meeting legal and comfort requirements
for offices, public spaces and other commercial applications.
HRV units can be controlled individually or integral with
the air conditioning system (Daikin VRV or Sky Air series).
When used in conjunction with an air conditioning system
the HRV unit enables the cooling or heating load placed on
the air conditioning system to be reduced significantly while
maintaining the required fresh air ventilation rates.
Essentially, the Daikin VAM HRV system takes out dirty indoor
air and pushes in fresh outdoor air to the rooms of your building
exchanging heat and humidity between supply and exhaust air,
which brings outdoor air close to indoor conditions and thus
recovers energy loss.

- The Daikin VAM system can be installed in a false ceiling
or under the floor.
- The heat exchange element uses a High Efficiency Paper
that has superior moisture-absorption and humidifying properties.
- The heat exchange between exhaust and supply air is arranged
automatically. This results in a considerable energy loss
reduction.
- Because of the automatic heat exchange there is 28% less
load on the air-conditioning system. This results in a lighter
(thus cheaper) overall air conditioning installation.
- The exchange in heat reduces the energy consumption of
the air conditioning system. And in mid-season the ventilation
system can work independently and thus replace the air-conditioning
system.
- The unit can work in two modes:
- Total heat exchange mode In total heat exchange
mode the ventilator exchanges the heat between the
exhaust air (from indoor) and the supply air (from
outdoor) by means of a heat exchange element. This
avoids cold draught when the outdoor air is colder
than the indoor air.
- Bypass mode In bypass mode the ventilator will
not exchange heat between exhaust and supply air
by means of bypassing the heat exchange element.
The outdoor air is brought directly into the room.
- The centralised remote control allows the user to choose
a wide range of control systems that integrate air conditioning
and ventilation.

FRESH-UP operation
Both the excessive supply mode and the excessive exhaust
mode are selectable. This function allows the VAM to create
a more comfortable air environment whether the occupied space
is required to be pressurised or de-pressurised.
