VTS Ventus VVS650 [22/55] Run around coil

VTS Ventus VVS055 [22/55] Run around coil
Design and application
» Rotor made of aluminum with shaft
suspended on bearings, installed in
steel housing.
» Rotor lling – two layers of
alternately winded aluminium foil
– one at, the other – corrugated –
making small ducts for the air.
» Rotor drive system with smooth
revolutions control enabling to
maintain highest recovery efciency
and to adjust degree of recovery
performance.
» Purge zone reducing the
cross-contamination effect of
contaminated exhaust air to supply
to absolute minimum.
» Set of gaskets installed both on the
wheel outer edge and bar separating
supply from exhaust air being an
additional protection against cross-
contamination.
» Rotary heat wheel recovers sensible
heat from return air to supply, which
passes the unit in opposite direction.
The process enables heat recovery
in winter time, same as cool recovery
in summer.
» Humidity recovery from return
to supply in case the rotor pad
temperature is lower than dew point
of return air – typically during winter
season.
Specication
» Up to 86% of energy recovery,
depending on airow rate and its
velocity in the heat wheel window.
ROTARY HEAT WHEEL
Design and application
» Hexagonal heat recovery
recuperator made of crosswise
stamped aluminum plates, between
which supply and exhaust air
passes alternately in counterow
arrangement.
» As standard, the recuperator is
equipped with by-pass damper,
enabling its securing against
frosting and heat recovery capacity
regulation.
» Optionally, the recuperator can be
equipped with integrated mixing box.
» The recuperator provides sensible
heat recovery for warmer air to the
colder one. For winter season –
recovery of heat from return air to
supply. For summer – recovery of
chill from return air to supply.
Specication
» Energy recovery at very high supply
and exhaust air stream separation
(reaching 99,9%).
» Heat recovery reaching up to 93%
depending on ow rate face velocity
of the air passing the recuperator.
COUNTERFLOW HEXAGONAL RECUPERATOR
Design and application
» Recuperator made of crosswise
stamped aluminum plates, between
which supply and exhaust air
passes alternately in counterow
arrangement.
» As standard, the recuperator is
equipped with by-pass damper,
enabling its securing against
frosting and heat recovery capacity
regulation.
» Optionally, the recuperator can be
equipped with integrated mixing box.
» The recuperator provides sensible
heat recovery for warmer air to the
colder one. For winter season –
recovery of heat from return air to
supply. For summer – recovery of
chill from return air to supply.
Specication
» Energy recovery at very high supply
and exhaust air stream separation
(reaching 99,9%)
» Heat recovery reaching up to 80%
depending on ow rate face velocity
of the air passing the recuperator.
CROSSFLOW PLATE HEAT RECUPERATOR
Design and application
» Set of two water coils – one in
supply, the other one in exhaust
airstream.
» The coil in return airstream recovers
the heat (cooler) and passes it
to the coil in the supply air (heater)
by means of heat-transfer uid
(water-glycol mixture). In case of chill
recovery, entire process is reversed.
» System applied for supply and
exhaust air handling units installed
remotely to each other."
Specication
» Indirect Energy recovery
(sensible heat) at 100% supply
and exhaust airstreams separation.
» Max heat-transfer uid operation
pressure: 1,6MPa=16bar
(tested 21 bar).
» Max glycol concentration: 50%.
RUN-AROUND COIL
Design and application
» Section equipped with two air inlets/
outlets aided with dampers, enabling
regulation of fresh and recirculation
air share (recirculation).
Specication
» Direct Energy recovery (sensible
and latent heat) resulting from partial
mixing of fresh air with return one.
» Control of fresh air share in entire
airow supplied to handled spaces.
» Working temperature range:
-40 ÷ +70°C.
