Dehumidification systems for private indoor
swimming pools, wellness and therapy areas.
Why install a dehumidification system
in an indoor pool?
A high degree of water evaporation is
common with indoor pools, especially
in combination with elevated air
temperatures, leading to high indoor
humidities and an oppressive atmosphere.
Without controlling the humidity, the
stay in an indoor swimming pool can
feel uncomfortable and the subtropical
climate might lead to cardio-vascular
problems. Furthermore, there is a risk
that the condensation on metal fixtures,
exterior walls or glass surfaces may lead
to the formation of mold, corrosion and
cause mustiness. When this occurs, it could
eventually lead to damage to the building,
resulting in costly renovation and business
interruptions.
An efficient air dehumidification system,
which actively decreases the humidity
levels, ensures a pleasant and comfortable
atmosphere for visitors and staff while
helping to maintain the building.
Method for dehumidifying room air
A current and common way of lowering
the humidity inside a swimming pool is by
a constant and uncontrolled ventilation
of outdoor air. This method uses a fan to
discharge the moist and warm air from
the swimming pool to the outside, while
more arid outside air is drawn into the
indoor pool. Subsequently, this constant
supply of untreated air must be reheated,
which is associated with high energy costs.
Using ventilation in order to lower the air
humidity wastes energy and is an out dated
solution.
Specially designed swimming pool air
dehumidification systems, which operate
on the basis of a closed refrigeration cycle,
are a more energy-efficient approach of
controlling the humidity. Compared to a
simple ventilation system with an intake
and exhaust air system, a swimming
pool dehumidifier can be up to 60% more
efficient.
Types of dehumidifiers
Condair GmbH offers a wide range of
dehumidifier products for all types of pool
requirements:
n
Condair DP-W - chest-type wall mounted units for installation in the indoor
pool area
n Condair DP-R - wall-mounted units for
installation in an adjacent room
n Condair DP - units installed in the equipment room for circulating air operation
n Condair DP-HE - high-efficiency
dehumidifier for outdoor air operation
with cross-flow heat exchanger
All Condair swimming pool dehumidifiers
are based on the heat pump principle. The
heat emitted by the heat pump circuit has
an additional benefit of heating the indoor
pool area. This can lead to a considerable
saving in the operating costs of the heating
system.

CONDAIR DP-W
Wall-mounted dehumidifier
The Condair DP-W swimming pool
dehumidifier is a chest-type unit
mounted directly onto a wall in the
pool area. Five models are available
with a maximum dehumidifying
capacity of 49 to 190 l/day.
Installation is very simple with
low assembly costs and required
connections for just the electrical
power and condensation drain. The unit
has a slim depth of 260mm or 310mm,
with smart and durable housing, in
pure white RAL 9010, to blend perfectly
with the architecture of the swimming
pool area. The units are particularly
recommended for retrofitting. The
efficient R410A is used as refrigerant.
The thermal energy released by the
heat-pump circuit is completely
transferred back to the room, helping
to reduce heating costs. Optional hot
water or electric heaters are available
for additional heating if required to
quickly heat the air to the required
temperature in the swimming pool
area.
The internal control electronics ensure
the economic operation of the system.
All the control functions are easy to
operate. The refrigeration system of
the Condair DP-W incorporates only
high quality, branded components, and
housed inside a compact and stylish
enclosure. Alongside the optional hot
water or electric heater, electronic and
mechanical hygrostats, and standing
feet are also available, to suit the
requirements of the room.

CONDAIR DP-R
Remotely located dehumidifier
The Condair DP-R is recommended for
installations when the dehumidifier
needs to be housed away from the
swimming pool area, either due to
space or aesthetic reasons. With the
compressor and fans housed away from
the pool, any machine noise is reduced
to a minimum.
The Condair DP-R pool dehumidifier
is available in five different sizes with
a maximum dehumidifying capacity
ranging from 49 to 190 l/day.
This model is wall-mounted in a room
adjacent to the swimming pool. The
connection to the pool area is made
by using an optional 90° ducting kit
through the wall, leaving only the
supply and return air grilles visible.
The heat released by the heat pump
circuit is completely transferred back
to the room. This contributes to a
considerable saving in heating costs. In
addition, optional hot water or electric
heaters can rapidly heat the air to the
desired temperature in the swimming
pool area.

CONDAIR DP-C
Ceiling-mounted dehumidifiers
The Condair DP-C is a compact solution
for air dehumidification. The flat
design of this model makes it ideal
for mounting under the ceiling or
in a suspended ceiling. This type of
installation is particularly suitable
where there is no plant room or
the existing plant room is too small
to install a floor-mounted unit.
All emitting components, such as
compressors and fans, are located
outside the swimming pool area.
The Condair DP-C pool dehumidifiers
are available in five different sizes,
with a maximum dehumidifying
capacity of 49 to 190 l/day. As an
alternative to the optionally available
hot water-coil or electrical heaters, a
partial heat recovery unit is available
for transferring the waste heat from
the dehumidifier directly into the pool
water.

CONDAIR DP
Dehumidifier for the installation in the mechanical room
The Condair DP dehumidifiers can be
used in hotel indoor swimming pools,
wellness centres and therapeutic
areas. These units are installed in a
central utility room with ventilation
ducts channeling the air to the pool
area. This process of recirculating air
ensures a safe and energy-efficient
dehumidification system.
Ten different capacities are available
with dehumidification from 73 to
940 l/day, covering a wide range of
applications.
The recuperated thermal energy
from the high-performance heat
pump circuit is completely returned
to the room air. This helps reduce the
room’s heating costs. As a result of the
high-power output of the equipment,
the thermal energy is often sufficient
to maintain a constant temperature
inside the pool area. An optional
partial heat recovery system can be
installed to channel a portion of the
generated heat into the pool water.
This is particularly useful in a
therapeutic area, where high room
temperatures are needed. A partial
heat recovery system can prevent
overheating inside the pool area. An
optional extra of a hot water coil or
an electric heater can be provided for
additional heating of the indoor air or
to support the existing room heating
system.
A wide range of other options are
available to help meet the specific
requirements of the swimming pool.

CONDAIR DP HE
High-efficiency dehumidifier
The highly efficient Condair DP-HE
swimming pool dehumidifier is used
for humidity and temperature control
with simultaneous heat recovery
and external air supply, which can
be controlled automatically to offer
maximum comfort in the swimming
pool area. Seven models are available
with a maximum dehumidifying
capacity range from 133 l/day to 565
l/day while operating at recirculation
mode. When run at outdoor air
operation mode, the dehumidification
capacities can reach a maximum 1054
l/day.
Functional principle
A fan (G) draws in the very warm and
humid return air from the swimming
pool. The air flows through the air filter
(A) and passed through a cross-flow
heat exchanger (B). When the air flows
cross, some of the enthalpy content is
transferred to the supply air. After the
air passed through the cross-flow heat
exchanger, a part of this air stream
from the fan (C) can be discharged to
8
the outside. The remaining air is passed
through the direct evaporator heat
exchanger (D), where it is dehumidified
to the required level. Downstream
of the evaporator, the dehumidified
and cool air can be added and mixed
with a portion of the outside air (from
0% to 30%). An adjustable external
air flap (E) is used to regulate this
setting. Subsequently, the air mixture
is channelled through the second
inlet of the cross-flow heat exchanger.
The heat from the warm exhaust air
of the swimming pool is dissipated
and added to the cooler mixed supply
air. Consequently, the pre-heated air
passes through the condenser (F) and
is returned to the swimming pool as
supply air.

If the supply air does not reach the
required temperature by passing
though the condenser (e.g., with
very low outside air temperatures), a
downstream hot water heating coil (H)
is used to heat the air.
The proportion of the mixed outside
air is up to 30% of the total nominal
airflow. Adding outside air improves
the quality of the air inside the pool
area considerably. Furthermore,
depending on the outside air
conditions, the cross-flow heat
exchanger is used beneficial as a
pre-dehumidifier of the humid return
air. This requires less energy for the
actual dehumidification process via
the refrigeration circuit.
The twice use of the cross-flow heat
exchanger in the heat recovery leads
to an increased dehumidification
output of up to 30% and a lower
power consumption compared to
conventional dehumidifiers.
The energy efficiency can be further
optimized by using the optional
available energy saving setback
system which can be utilized while the
pool is not in operation.
The flexible control options guarantees
the best possible efficiency in
every operating mode and at every
utilization level.

Efficiency
One traditional method of
dehumidification that is still used
today is a simple ventilation and
exhaust system, where the damp air is
pushed out via a ventilator and drier air
streams come in from the outside. This
external air must then be reheated,
which requires a high amount of
energy.
A more efficient way to run
dehumidifiers is based on a closed
cooling circuit system. All Condair
industrial and indoor swimming
pool dehumidifiers work according
to the heat pump principle. The heat
generated by the heat pump circuit is
recycled to heat the indoor pool area.
This helps reduce operating costs and
makes it up to 60% more efficient when
compared to a standard ventilation
system.
Desiccant driers can be very efficient
when available energy from on-site
steam or warm water is combined with
the electrical regeneration heater. Using
hybrid regeneration heating saves
energy, particularly with larger systems,
to help reduce operating costs.
