The unit casing 1
The unit casing consists of a strong
frame construction with sound and
heat insulated panels. The frame
consists of a closed 1,3/1,5 mm
steel profile with surface of alu-zinc
AZ185 for corrosion protection. The
corners are die-cast and painted aluminum corners. The panels are also
corrosion protected with alu-zinc
AZ185 and consist of a sandwich
construction with two 0,8 mm steel
sheets and 50 mm mineral wool. The
unit sections are assembled with an
assembly bracket; Disc-Lock. Large
inspection doors provide easy access
for service and maintenance. It is
possible to lift off the doors, if needed. The doors are provided with lockable handles.
Plug fan DVE 2
The plug fan DVE has the impeller
fitted direct to the motor shaft and is
built into a soundproof unit casing.
The fan is a single inlet, free-blowing
fan where the unit casing acts as fan
housing. DVE has an efficiency of up
to 75% and a low noise level. On
large units, twin fans for parallel
operation are built-in. DVE can be
supplied with EC motor (IE4) in
Danvent DV 10-40, PM motor (IE4)
or AC motor (IE2). Fan impeller and
motor are statically and dynamically
balanced. Motor and fan are mounted on a sturdy frame, which is placed
on rubber vibration isolators, and the
fan inlet is connected to the unit with
a flexible connection.
Heat exchangers 3
The rotary heat exchanger DVC is
supplied in 3 types: Standard, enthalpy and sorption heat exchangers.
Generally, the rotary heat exchanger
has a high efficiency from 75% to
87% depending on operating conditions. It can recover moisture and is
the heat exchanger that requires the
least space. The enthalpy exchanger
recovers more moisture, and therefore contributes to the humidification
of the supply air. The sorption
exchanger dehumidifies the air more,
making it particularly suitable for
dehumidifying the outdoor air, for
example before cooling.
The plate heat exchanger DVQ is supplied in 3 types: Standard, high efficiency and counter flow heat
exchangers. Generally, the plate heat
exchanger has a high efficiency. It has
separated airflows, and thus the
transfer of odors to the supply air is
avoided. There is no transfer of moisture between the two airflows, and
so it can also be used for dehumidification. The standard cross flow
exchanger has an efficiency of up to
65%. The high efficiency cross flow
exchanger has an efficiency of up to
75%. These two types are supplied in
two variants: One made of aluminium
for comfort and one made of corrosion-resistant plastic-coated aluminium for aggressive environments. The
counter flow exchanger has an efficiency of up to 90% and is supplied
only in aluminium. The heat exchangers are fitted with by-pass for capacity control and have a built-in drip tray.
Quick Guide to Danvent DV |
Functions
The run-around coil heat exchanger
DVR has an efficiency of up to 70%
and is used, where the two airflows
must be kept completely separate, or
where the airflows are at a distance
from each other. For example on 2
different storeys. The DVR is a heat
exchanger system with circulating
water-glycol brine between the supply air heating coil and extract air
cooling coil. The transfer of energy is
done through a pipe system. Capacity
regulation is done through a shunt
system and a motor valve or by controlling the circulation pump.
Coils 4
The heating coil DVH is used for heating the supply air. The heating can be
effected by hot water or condensation of refrigerant. These coils consist
of copper tubes and aluminum fins.
Heating can also be affected with
electricity. These coils consist of heating elements of stainless steel and
have built-in safety control system. In
the standard version the coils are
built into the unit. More variants and
options are possible.
The cooling coil DVK is used for cooling the supply air. It can be effected
by cold water or direct evaporative
refrigerant. A cooling coil for evaporation has the liquid distributor
placed in the unit. These coils consist
of copper tubes and aluminum fins.
In the standard version, the coils are
built into the unit. More variants and
options are possible.
The change-over battery DVHK is
basically a cooling coil for cold water,
which can also be used for heating by
changing the water temperature from
cold to warm as required. Typically
used in connection with heat pumps.
Heat pump DVU-HP 5
The DVU-HP is an integrated reversible heat pump system built into a
unit section. The system consists of a
reversible heat pump and a rotary
heat exchanger that enables both
heating and cooling. The DVU-HP can
be supplied for Danvent DV 10 to 80.
The unit is equipped with 2 scroll
compressors (1 compressor for the
two smallest sizes DV 10 and DV 15),
and cooling/heating capacity is stepless variable in the range 5-100%.
The heat pump is based on R-410A
refrigerant. The DVU-HP is equipped
with a complete control system
which can communicate both with
Systemair Corrigo control system and
other control systems. Tested and
ready for operation from the factory.
Humidifier DVX
The humidifier is made as a complete
unit, which includes humidification
elements, tray and frame made of
stainless steel AISI 304, circulation
pump, irrigation regulation valves,
overflow, bleed-off regulation valve,
float valve for controlling the water
supply to the tray and valve for emptying the tray. The HU-CELL humidification elements are stainless steel
frames which contains corrugated
fiberglass plates arranged in crosschannel configuration. The function
of the humidifier is based on the
natural process that water evaporates when air passes a wet surface.
The humidifier can either be placed
in the supply air after a heating coil
or used as indirect adiabatic cooling
by placing it in the extract air before
a heat exchanger.
Damper 6
The dampers comply with tightness
class 3 according to EN 1751:2014.
The dampers have counter rotating
aerodynamically shaped damper
blades made of aluminium, which
ensures a low pressure loss when
open. The blades are equipped with
tight-fitting, rubber sealings, and are
mounted on sturdy, square shafts and
service-free, synthetic bearings. The
connection between the blades is a
rod drive located outside the airflow.
The bearings in the pivoting system
are made of brass. The blades can be
supplied insulated and/or anodized.
The following types of dampers can
be supplied: DVA shutoff damper with
horizontal connection, DVB shutoff
damper with vertical connection, DVM
mixing damper with 2 built-in dampers, DVP mixing damper with 3 builtin dampers. All dampers are equipped
with position indicator and are prepared for internal damper motor.
Filter 7
The compact filter DVG is a basic filter
class G4 according to EN779:2012 with
a short building length. It is designed
on pleated filter principle. The DVG can
be used as pre-filter and thereby
extend the life of the main filter.

heavy traffic. The filter cells are fixed
with a simple but effective fixing
system of transverse locking rails
which can easily be activated using a
large handle. This ensures that the
filter cells are tight and meet tightness requirement according to
EN 1886:2008.
Sound attenuator DVD
The sound attenuator DVD is an
absorption attenuator with baffles.
DVD is used to reduce the sound
power level from the air handling unit
to the duct system. The baffles have
a surface coating which prevents the
entrainment of the sound absorbing
material. The surface coating is available in two variants: A standard lining, which is a hard wear-resistant
material where the baffles can be
cleaned by dry cleaning. As well as a

Quick Guide to Danvent DV |
SystemairCAD
Danvent DV units are designed in
SystemairCAD. It is an advanced
design programme which ensures an
optimal dimensioning of the unit’s
functions. The programme is free and
can be downloaded from
www.systemair.com. SystemairCAD is
very user-friendly and allows a simple and quick way to combine the
unit functions as required. When the
unit design is finished, SystemairCAD
makes a technical calculation and
automatically generates a complete
technical documentation in pdf format for the selected unit.
The documentation includes the
following highlights:
• Frontpage with a summary of the
most important technical data of
the selected unit: Airflow, external
pressure drop, motor data, overall
dimensions, weight, efficiency of
the heat exchanger, SFP, performance of the heating coil and
sound power level.
•D
etailed drawing of the unit’s construction, dimensions and duct
connections.
• Sound power level divided into
frequency bands.
• Technical specifications of all components included in the unit such as
pressure loss, dimensions, electric
data, efficiencies, air temperatures,
COP, EER, description of materials,
ErP, power input, etc.
• Shipping, dimensions and weights
of all parts.
• The control system including flowchart, external electrical components, description of control functions, alarms, and safety functions,
as well as communication options.
•M
olliere diagram with summer
and winter conditions.
• SystemairCAD includes a feature
that can automatically generate a
complete consultant text adapted
to the selected unit.
The drawn to scale drawings from
SystemairCAD can be exported to
other CAD software. There are the
following options:
• Export of DXF files 2D and 3D
• Export of DMR files to
Autodesk Revit.
• SystemairCAD project files can be
opened directly in AutoCAD via
MagiCAD plugin and in Autodesk
Revit via Revit plugin.
